DAAN AND M. MULDER This report presents data of the monitoring program o f macrozoobenthos in the Dutch Continental Shelf (DCS) of the North Sea, a cooperation between the National Institute for Coastal and Marine Management/RIKZ (Rijkswaterstaat), the North Sea Directorate (Rijkswaterstaat) and the Department of Marine Ecology (NIOZ) NETHERLANDS INSTITUTE FOR SEA RESEARCH Monitoring Macrozoobenthos of the North Sea NIOZ-RAPPORT 2002-1 Monitoring macrozoobenthos North Sea 2001 1. S u m m a r y In this report the results are presented of a macrobenthos survey on the Dutch Continental Shelf (DCS), carried out in spring 2001. The survey forms part of the 'Biological monitoring programme of marine waters' (MON*BIOLOGIE, generally referred to as ‘BIOMON*) which was initiated by the National Institute for Coastal and Marine Management (RIKZ). The purpose of the programme is to obtain insight into the year-toyear variations of the macrobenthic assemblages and to detect trend-like changes, that possibly indicate anthropogenic influences on the marine environment {e.g. eutrophication, pollution, beam-trawl fishery). Within the framework of this project fieldwork is carried out every year in spring. In 2001 the 100 BIOMON stations were sampled in the period between February 27 and April 4. On the basis o f the results collected in 2001 and previous years an analysis is made of the trends and fluctuations of some selected species and o f basic community attributes over the period 1986-2001. The community attributes studied were the diversity, abundance and biomass of the total macrofauna and of the 4 major taxonomic groups. Temporal variation or trends were investigated separately for each of the four subareas in the DCS i.e. the Coastal, Offshore areas, Dogger Bank and Oyster Ground. The conclusions of this study can be summarized as follows: 1. The sediment composition in the four subareas was quite similar to that found in previous years. Also at most of the individual stations the median grain size and silt content of the sediment had hardly changed. There were only three stations with strong year to year differences in sediment composition. At the stations OFF 2 and OFF 6 the median grain size strongly fluctuated and at station OYS 8 the silt content. It is suggested that these stations are situated at a sharp local gradient. 2. At the community level, there were only a few slight changes compared to preceding years. In the offshore area and in the coastal area there seemed to be a tendency for increased diversity. This was not due to increased species richness but to a more even distribution in the abundance of the various species. With respect to the share of the different taxonomic groups to the total biomass, a decrease has been observed in previous years in molluscs, particularly at the Dogger Bank and in the Oyster Ground. This decrease has come to an end in 2001 and turned into an increase. Since molluscs also increased numerically, the increase in biomass is caused by higher densities rather than by a larger size of the animals. 3. At the Dogger Bank a few species showed a remarkable decrease. The polychaete Nephtys cirrosa shows a decrease from 2000 onwards, the sand star Acrocnida brachiata and the bivalve Mysella bidentata from 1999 and the polychaete Aricidea 1 Monitoring macrozoobenthos North Sea 2001 minuta decreased in 1997 and has no longer been found since 1999. On the other hand the population density of the gastropod Euspira nitida (formerly called Natica alderi) had recovered from a dip in the period 1998 - 2000. The occurrence of Ensis phaxoides is new for the Dogger Bank. Further, living specimens of the bivalve Gouldia minima and the gastropod Turbonilla pusilla have not been found on the DCS before. 4. In the Oyster Ground the decreasing trend that has been observed in previous years in the brittle star Amphiura filiformis and the polychaete Nephtys hombergii had turned into an increase in 2001. However, densities of A. filiform is were still low at the Frisian Front. There was a number of species that have not been found before during the BIOMON programme. The occurrence of the polychaete Nephtys assimilis is new for the Oyster Ground. The records o f the polychaete Sabella penicillus, the bivalves Montacuta tenella and Gari costulata and the gastropods Turbonilla pusilla and Roxania utriculus are probably new to the DCS. 5. In the offshore area, a slightly increasing trend that has been observed in the sea urchin Echinocardium cordatum in the preceding years has come to an end in 2001. In contrast, the gastropod Euspira nitida showed a recovery of populations from 2000 onwards. Station OFF 33 that in 2000 had shown a rich fauna that was clearly different from the other stations in the offshore area was still rich in 2001, but the fauna composition did not show ‘exotic’ elements. 6. In the Coastal area there seemed to be a recovery of the populations of the gastropod Euspira nitida. After an 8 year period o f very low densities the species returned at 5 stations, albeit in low numbers. The bivalve Tellina fabula also showed a steady increase, after a dip in the second half of the nineties. At stations where banks of Spisula subtruncata or Ensis americanus occurred, biomass values were very high. 2 Monitoring macrozoobenthos North Sea 2001 2. S a m e n v a t t in g In dit rapport worden de resultaten gepresenteerd van een macrobenthos bemonstering die in 2001 werd uitgevoerd op het Nederlands Continentale Plat (NCP). De bemonstering vond plaats in het kader van het ‘Biologische Monitoring Programma Zoute Wateren’ (MON*BIOLOGIE, gewoonlijk aangeduid ais ‘BIOMON’), dat geïnitieerd is door het Rijksinstituut voor Kust en Zee. Met het project wordt beoogd inzicht te krijgen in de jaarlijkse fluctuaties van de macrobenthos gemeenschappen en vast te stellen of er op de langere termijn trendmatige veranderingen optreden. Dergelijke veranderingen zouden onder meer kunnen plaats vinden ais gevolg van anthropogene activiteiten (bijv. eutrofiëring, verontreiniging, boomkorvisserij). In het kader van dit project wordt jaarlijks veldonderzoek uitgevoerd in het voorjaar. In 2001 zijn de 100 BIOMON stations tussen 27 februari en 4 april bemonsterd. Aan de hand van de gegevens die in 2001 en voorgaande jaren zijn verzameld is een overzicht verkregen van de trends en fluctuaties bij een aantal geselecteerde soorten en een aantal kenmerken van de benthische gemeenschap ais geheel over de periode 1986 2001. Deze set kenmerken bestaat uit de diversiteit, de dichtheid en biomassa van de totale fauna en de 4 belangrijkste taxa. Temporele variatie en trends zijn voor vier subgebieden van het NCP, de Kustzone, het Offshore gebied, de Doggersbank en de Oestergronden, afzonderlijk onderzocht. De conclusies van deze studie kunnen ais volgt worden samengevat: 1. De doorsnee sedimentsamenstelling in de vier subgebieden vertoonde grote gelijkenis met die welke in voorgaande jaren werd aangetroffen. Ook op de afzonderliojke stations werden meestal geen grote veranderingen in mediane korrelgrootte of slibgehalte gevonden. Er waren slechts drie stations waar sterke jaar-op-jaar fluctuaties werden gevonden in de sedimentsamenstelling. Op de stations OFF 2 en OFF 6 varieerde de mediane korrelgrootte sterk en op station OYS 8 het slibgehalte. Verondersteld wordt dat deze stations gesitueerd zijn in gebiedjes waar scherpe locale gradiënten voorkomen. 2. Op community niveau waren er slechts enkele kleine veranderingen ten opzichte van de voorgaande jaren. In het offshore gebied en in de kustzone leek er sprake van een toegenomen diversiteit, niet in de zin van een toegenomen aantal soorten, maar meer wat betreft een meer evenwichtige verdeling in de dichtheden van de verschillende soorten. Met betrekking tot het aandeel van de verschillende taxonomische groepen in de totale biomassa is in voorgaande jaren een afname waargenomen bij de mollusken, met name op de Doggersbank en in de Oestergronden. Deze afname is in 2001 3 Monitoring macrozoobenthos North Sea 2001 3. 4. 5. 6. omgebogen in een toename. Aangezien mollusken ook numeriek toenamen moet de biomassa toename eerder verklaard worden door hogere dichtheden dan door een gemiddeld grotere afmeting van de organismen. Op de Doggersbank vertoonden enkele soorten een opmerkelijke afname. De polychaet Nephtys cirrosa neemt af sinds 2000, de slangster Acrocnida brachiata en de bivalve Mysella bidentata vanaf 1999 en bij de polychaet Aricidea minuta zette de afname in 1997 in. Deze laatste soort is sedert 1999 niet meer gevonden. Aan de andere kant bleek de gastropode Euspira nitida (vroeger Natica alderi genoemd) zich te hebben hersteld van een dal in de periode 1998 - 2000. Het voorkomen van de bivalve Ensis phaxoides is nieuw voor de Doggersbank. Verder werden levende exemplaren van de bivalve Gouldia minima en de gastropode Turbonilla pusilla aangetroffen. Beide werden nog niet eerder op het NCP gevonden. In de Oestergronden is aan de afnemende trend die in de voorgaande jaren is waargenomen bij de slangster Amphiura filiform is en de polychaet Nephtys hombergii een eind gekomen. Bij beide soorten was in 2001 in het algemeen sprake van een toename. Niettemin waren de dichtheden van A. filiform is nog steeds laag op het Friese Front. Er waren meerdere soorten die nog niet eerder gevonden zijn in het kader van het BIOMON-programma. Zo werd de polychaet Nephtys assimilis nog niet eerder in de Oestergronden aangetroffen. Het voorkomen van de polychaet Sabella penicillus, de bivalven Montacuta tenella en Gari costulata en de gastropoden Turbonilla pusilla en Roxania utriculus is waarschijnlijk nieuw voor het NCP. Aan de licht toenemende trend die in de voorgaande jaren in het offshore gebied is waargenomen bij de hartegel Echinocardium cordatum is in 2001 een eind gekomen. Populaties van de gastropode Euspira nitida vertoonden daarentegen een herstel vanaf 2000. Station OFF 33 dat in 2000 een rijke fauna had laten zien, die duidelijk afweek van de overige stations in het offshore gebied, bleek opnieuw rijk, maar de fauna bevatte geen ‘vreemde' elementen. In de kustzone leek er sprake van een herstel van de populaties van de gastropode Euspira nitida. Na 8 jaar van zeer lage dichtheden bleek de soort op 5 stations weer voor te komen, zij het in nog geringe aantallen. De bivalve Tellina fabula vertoonde ook een gestage toename, na een dieptepunt in de tweede helft van de jaren negentig. Op stations waar banken voorkwamen van Spisula subtruncata of Ensis americanus waren de biomassagetallen zeer hoog. 4 Monitoring macrozoobenthos North Sea 2001 3. I n t r o d u c t io n In 1989 the B iological M ONitoring programme of marine waters (project MON* BIOLOGIE) was started with the goal to study the temporal variation of the marine ecosystems on the Dutch Continental Shelf (DCS) including the Wadden Sea and the Delta area. It is an initiative of the National Institute for Coastal and Marine Management (RIKZ) of Rijkswaterstaat in association with several Dutch institutes (Yland, 1995). The biological monitoring programme comprises besides the macrobenthos also plankton, fish, seagrass, hard substrate populations, seabirds and mammals. This report presents the data collected during the macrobenthos survey carried out in spring 2001. Further the results of the 2001 survey are compared with the BIOMON data collected in previous years (1991-2000) and those obtained during the ICES North Sea Benthos Survey (ICES-NSBS, 1986) and the MILZON-BENTHOS programme (1988-1993). In 1990 a pilot study of the BIOMON project was carried out at 7 locations on the DCS and the results are also included in the data base. The aim of the BIOMON programme is to obtain insight in the spatial and temporal variation in the composition of the macrobenthos and to detect possible trendlike changes on the DCS as a whole or in parts of it. During the first years (1991-1994) there were 25 stations located along 5 transects perpendicular to the Dutch coast. At these stations 5 replicate boxcore samples were collected each year. Athough in this way a rather detailed picture was obtained of the fauna composition at each of these stations, it was argued that (changes in) the macrobenthos composition of the DCS as a whole could better be studied by spreading the sampling effort over a larger number of stations. Therefore, from 1995 onwards the sampling strategy changed and each year 100 stations were visited, that were selected according to a stratified random sampling design in each of the 4 subareas of the DCS, i.e. Dogger Bank, Oyster Ground, Offshore area and Coastal area (Fig. 1). The number of stations within each subarea was proportional to its surface area. At each station only one sample was taken. The 100 stations that were selected include the 25 original BIOMON stations. The selection procedure is described in more detail by Essink (1995) and Holtmann et al. (1996) The analysis of the results obtained in previous years (Daan & Mulder, 2001) has shown that there were generally no clear trends at the community level (faunal density, biomass, biodiversity parameters) in the 4 subareas. However, in most subareas there seemed to be a slight decrease in the contribution of molluscs to the total benthic biomass. At the species level there was a clear downward trend in the abundance of the brittle star Amphiura filiform is in the Oyster Ground from 1993 onwards. Particularly at 5 Monitoring macrozoobenthos North Sea 2001 the Frisian Front a dramatic decrease was observed in the abundance of this species. Further there was a decrease in the abundance of the polychaete Nephtys cirrosa and the gastropod Natica alderi in the Offshore area and the Coastal area. The latter species also decreased at the Dogger Bank. The new data will show to what extent the apparent trends observed in previous years continued in 2001. 4 . M a t e r ia l and m ethods To ensure that any changes that are observed are not due to methodological differences, the procedures for sampling and processing the fauna samples are standardized (Essink, 1991) and have remained unaltered since the beginning o f the monitoring project in 1991. 4.1. S a m p l i n g In 2001 the BIOMON stations were sampled in the period February 27 to April 4. Most stations have a water depth >5 m and were visited with the RV Mitra or the RV Arca (North Sea Directorate, RWS). However, two stations in the Coastal subarea with a water depth less than 10 m, viz. COA 13 & 14 were sampled with the RV. Delta (RWS). Fig. 1 shows the positions of the stations . The exact geographical positions o f the 100 stations, together with the delta codes and selected abiotic characteristics (depth/sediment) of the stations are summarized in Table la/b. More general information about the cruise carried out with the RV. Mitra and the weather conditions during this part of the survey in 2001 can be found in the cruise report of Rijkswaterstaat (Anonymous, 2002). 4 .2 . S a m p l e treatm ents At each station two boxcore samples (0.068 m2, minimal depth 15 cm) were taken. One of the samples was used for sediment analysis and the other sample was washed through a sieve with round holes ( 1 mm) to collect the macrobenthic fauna. For sediment analysis 2 pooled subsamples (3.4 cm 0 , depth 10 cm) were immediately stored at -20°C. The residue of the macrobenthos samples was preserved in a borax-buffered solution o f 4-6 % formaldehyde in seawater and stored at room temperature. In the laboratory the macrobenthos samples were stained with rose-bengal and washed over a set of nested sieves with 0.7 mm as the smallest mesh size to facilitate 6 Monitoring macrozoobenthos North Sea 2001 sorting. The macrofauna was identified to species level, except for some notoriously difficult taxa such as anthozoans, phoronids, priapulids and nemerteans, and subsequently counted. Juvenile macrobenthic animals which because of their size could not be identified to species level were recorded on higher taxonomic levels, usually the genus level. Sizes (nearest 0.5 mm) were recorded for most molluscs and echinoderms. 4 3 . ASHFREE DRY WEIGHT The ash-free dry weight (AFDW) of the different taxa was determined in one of the following ways: • Molluscs and echinoids: By means of length-AFDW relationships of the form W =a*Lb (W=AFDW in g and L=length in mm). • Polychaetes. other worms. larger crustaceans and ovhiuroids: Indirectly, by converting the (blotted) wet weight into AFDW by means of conversion factors provided by Rumohr et al. (1987) and Ricciardi & Bourget (1998). W et weights were measured with a M ettler PJ300 balance to the nearest mg. • Remaining taxa: Directly, by drying a sample at 60 °C for at least 60 hours and subsequently incinerating at 520 °C for 2 hours (Duineveld & W itte, 1987). Small molluscs, amphipods and cumaceans were assigned an average individual AFDW of 0.2-0.5 mg. The same value is used by Holtmann & Groenewold (1992; 1994) in their analysis of macrobenthos from the MTT ZO N -B F N T H O S project in the southern North Sea between 1991 and 1993. This estimated individual weight is based on previous determinations of the AFDW of the taxa in question (Duineveld; Holtmann, unpubl.). 4 .4. S t a t is t ic s In addition to the density (ind./m2) and biomass (g AFDW /m2), the diversity of each macrobenthos sample was calculated. In the literature a suit of biodiversity indices have been used to identify possible changes of the benthic fauna (Hill, 1973; Peterson, 1977; Pearson & Rosenberg, 1978; Harper & Hawksworth, 1994). In this report, we used three indices each representing a different aspect of the faunal diversity. The species richness 7 Monitoring macrozoobenthos North Sea 2001 (Hillo) stands for the number of species per boxcore sample and is the simplest index. The other two indices, the Shannon-Wiener index (H’) (Shannon & Weaver, 1949) and the Simpson index (D) for dominance (Simpson, 1949), are based on the proportional abundances of the individual species in the samples. The Simpson index is sensitive to the abundance only of the more plentiful species and can therefore be regarded as a measure of dominance (Hill, 1973). A high value for Simpsons index means low diversity, whereas a high value for the Hillo or Shannon-Wiener index indicates high diversity. 4 .5 . S e d i m e n t a n a l y s is At each station shown in Fig. 1, two subsamples were taken from an intact boxcore sample and subsequently pooled for laboratory analysis o f the sediment composition (e.g. grain size, content of calcium carbonate). The grain size was analysed with a Malvern Particle Sizer by the laboratory of the National Institute for Coastal and Marine Management (RUCZ, Middelburg). Two parameters were derived from the grain size data: the median grain size (pm) and the percentage (by weight) of mud. We here define mud as the total fraction mineral particles < 63 pm. However, for comparison with previous years we also calculated the fraction 16-63 pm. Sediment types were classified on the basis o f the median grain size as follows: Characterisation of the sedimenttype according to the median grain size (after Gullentops et al., 1977). < 175 pm Very fine sand 175 - 250 pm Fine sand 250 - 300 pm Medium-fine sand 300 - 350 pm Medium-coarse sand > 350 pm Coarse sand 8 Monitoring macrozoobenthos North Sea 2001 5. Re s u l t s a n d d is c u s s io n 5 .1 . S e d im e n t c o m p o s it io n The median grain size and silt content of the sediment at the stations sampled are listed in Table 1. Spatial and temporal patterns are illustrated in Fig. 2, 3 and 4. The spatial pattern in the sediment composition in 2001 was quite similar to that in the preceding years. A look at the mean median grain size in the 4 subareas between 1995 and 2001 (Fig. 4) shows that the grain size is not only very stable, but that the variation around the mean is extremely small. Also at most of the individual stations the median grain size did not substantially change compared to preceding years. A comparison between the values measured in 2001 (Fig. 2) and those found in previous years shows that in more than 80% the size class did not change and that in most of the other cases the difference was not more than 1 size class. There are, however, two exceptions. At station OFF 2, north of Schiermonnikoog, the median grain size was about 340 pm in 1997 and 1999, but substantially lower, about 210 pm, in the other years. In our previous report we already suggested that OFF 2 is situated at a sharp local gradient where the sediment changes from fine sand into medium-coarse sand within a short distance. As a consequence, small year to year differences in sampling position could result in rather strong differences in sediment composition. At station OFF 6, west of Texel, a different situation was met. Here the median grain size was 375 pm in 1995 and dropped to values of about 310 pm in the period 1996 - 2000. In 2001 an even lower value of 200 pm was found. It is not clear how this should be explained. Maybe the situation is similar to that at OFF 2, i.e. a sharp local gradient. However, the possibility that there has been a change in sediment composition over time should also be considered. This would imply that there has been either a deposition of fine material at OFF 6 or a disappearance of the larger size fractions. If a deposition of fine material had occurred one might expect that silt concentrations had increased compared to previous years. However the silt fraction was at the same low level (0.5%) as in previous years. On the other hand a selective disappearance of the larger size fractions can only be explained when there has been a local physical disturbance, probably by human activities. It is not known whether such activities have taken place at OFF6. The distribution of silt in the sediment also showed the same spatial pattern as in the preceding years (Fig. 3). There was only one station where a substantial difference was found in the silt content compared to 1999 and 2000. This was station OYS 8, at the southern edge of the Frisian Front. In the preceding years the silt concentrations at OYS 8 were between 22 and 28 % but in 2002 it was less than 9 %. In this case we know that the 9 Monitoring macrozoobenthos North Sea 2001 station is located in an area with a sharp north-south gradient in silt concentrations which is linked up with a relatively steep depth gradient. This means that a small difference in positioning possibly could have a strong effect on the silt content measured. Another explanation could be that the local depth is critical with respect to sedimentation and resuspension of silt. This could be a cause of strong temporal variability of silt contents. 5.2. D is t r ib u t io n o f t h e m a c r o b e n t h ic f a u n a in 2001 5.2.1 Diversity, density and biomass A total number of 208 species/taxa were identified in the 100 boxcore samples in 2001, including 16 that were identified to genus level only (most juveniles) and 12 higher taxa (identified to family level or higher). The total number o f taxa is within the range of previous years (181 - 231). The distribution of the species over the stations (presence/absence) and the scientific names are given in A ppendix-1. The basic data on macrobenthic abundance, biomass and diversity are listed in Appendix-2. The mean number of species per sample (Hill 0) was, like in previous years, the highest on the Dogger Bank and the lowest in the coastal and offshore area (Table 2, Fig. 5,8). There is an overall patterm of high species richness in the North (below the 30 m depth contour) and low species richness in the south. In neither of the subareas a clear long term trend could be observed in species richness. In the offshore area there were four stations with a relatively rich fauna. The samples collected at OFF 1, 4, 5 and 33 all contained more than 30 species. OFF 33 had been identified already in 2000 as a remarkably rich station in an area, that is poor in fauna. The other three stations are situated just south of the 30 m isobath, so close to the rich Oyster Ground. Therefore, the relatively high number of species at these stations is not surprising. The highest Shannon W iener diversity was also observed at the Dogger Bank, whereas Simpson’s dominance was the lowest in this area (Table 2, Fig. 9,10). Numbers o f individuals are more or less equally distributed over the different species and there are no species which strongly dominate the fauna community by number. The lowest Shannon Wiener diversity was found in the offshore and coastal area. However, there seems to be a slight tendency for increasing diversity in these areas since the middle of the nineties. On the other hand Sim pson's dominance seems to decline in this period. This might indicate that dominance by one or a few species is less pronounced than it has been and that the fauna is more equally distributed over the different species. Indeed, it seems that some polychaete species (viz. Lanice conchilega, Magelona mirabilis and 10 Monitoring macrozoobenthos North Sea 2001 Spiophanes bombyx) which often have dominated the fauna in the two areas, were not so abundant in 2001. The mean fauna density was as usual the lowest in the offshore area (Table 2, Fig. 6). The fauna in this area was dominated by crustaceans and polychaetes O f the other three areas the density was the highest in the Oyster Ground, but there were no large differences. The Oyster Ground had particularly high numbers of echinoderms and molluscs. At the Dogger Bank Crustaceans and polychaetes were the dominant groups, in the coastal area molluscs and polychaetes. There were no trendlike changes in fauna abundance (Fig. 11). Biomass values were generally hardly different from those in 2000 (Fig. 12). There does not seem to be a trendlike change. The highest mean biomass, but also the strongest variation was found again in the coastal area (Fig. 7). As in previous years the peak values found at some stations in the coastal area were generally caused by dense populations of the mollusc Spisula subtruncata or by Ensis americanus. W ith respect to the share of the different taxonomic groups to the total biomass a shift has been noticed in some areas in 1999. Particularly at the Dogger Bank and in the Oyster Ground the contribution of molluscs had decreased. Since this decrease was compensated for by other taxa, there was no overall change in biomass. Mollusc biomass in 2000 was still at the low level of 1999. However in 2001 we can see an increase of mollusc biomass, both in an absolute sense and as share in the total biomass. Since molluscs increased also numerically in three of the areas, the increase in biomass is caused mainly by higher densities, rather than by a larger size of the animals. 5 .2 .2 . T e m p o r a l v a r i a t i o n in d e n s i t y a n d b io m a s s o f i n d i v i d u a l s p e c i e s Figs. 13-16 illustrate the temporal variation in density or biomass of a number of individual species in the 4 subareas during the period 1986-2001. D o sser Bank (Fig. 13a-c) On the Dogger Bank there were a few species that showed a remarkable decrease in 2001. The sand star Acrocnida brachiata, the bivalve Mysella bidentata and the polychaetes Nephtys cirrosa and Arcidea minuta occurred in lower densities than ever in the nineties. A. brachiata and M. bidentata show a decrease since 1999, but of these species there were still several tens of individuals per m 2 on average in 2001. N. cirrosa occurred already in 11 Monitoring macrozoobenthos North Sea 2001 low abundance in 2000, but that was supposed to be only a temporal dip. However, in 2001 there was a further decrease and the species was found at only two stations. In A. minuta the decrease had started already in 1997 and from 1999 onwards the species has no longer been found. The gastropod Euspira nitida (formerly called Natica alderi) showed an increase compared to previous years. The species was found in low numbers by the end of the nineties, but in 2001 population densities have recovered to a level similar to that before 1998. The densities of other species that in previous years have been found to be relatively abundant were more or less stable in 2001. The brittle star Amphiura chiajei that colonised the Dogger Bank area in 1999 (Daan & Mulder, 2001) was abundant again in 2001. On average it was found in densities of 150 in d .m '. The occurrence of Ensis phaxoides is new for the Dogger Bank. The species was found at two stations. We could find only a very few mentions of living E. phaxoides on the DCS. The species has been found in beam trawl hauls at two stations in the offshore area in the seventies by van Noort et al. (1979, 1984). Further the species was found in two van Veen grab samples in the south-western Oyster Ground (Creutzberg, unpubl. data). Further we found two species that probably are new to the Dutch malacofauna. Living specimens of the bivalve Gouldia minima and the gastropod Turbonilla pusilla. have, to our knowledge, not been found on the DCS before. We found living T. pusilla also at one station in the Oyster Ground and at one station in the offshore area. In previous years we sometimes found empty shells of the species. The occurrence of some new species on the Dogger Bank did not lead to increased diversity in this area. Both, the number of species per sample and the Shannon-Wiener index were in the same order as found in previous years. Apparently, the number of samples in which the species were found was too low to have a substantial effect on the diversity. However, the total number of species (87) on the Dogger Bank in 2001 was higher than found in any of the previous years (66 to 80) and the new species have certainly contributed to this overall high species richness. Oyster Ground (Fig. 14a-c) In previous years a declining trend has been observed in the brittle star Amphiura filiformis and the polychaete Nephtys hombergii. In 2001 this decrease seems to have come to an end. Both species showed an overall increase in their abundance. Nevertheless, the densities of A. filiformis at the Frisian Front were still low compared to 12 Monitoring macrozoobenthos North Sea 2001 the numbers that were found here in the early nineties. Further, relatively high numbers were found of the bivalves Corbula gibba and Nucula nitidosa (formerly called N. turgida). The other more or less abundant species showed stable densities. There was a number of species that have not been found before during the BIOMON programme, or that are even completely new to the Dutch fauna. The polychaete Nephtys assimilis that was found at OYS 36 has previously been found only in the ‘Loswal' area west of Scheveningen (Aquasense, 1996,1997; Kluijver & van Nieuwenhuizen, 1998). For another polychaete, Sabella penicillus, we could not find any reference for its occurrence on the DCS. The other new species are all molluscs. The bivalve Montacuta tenella was found at four stations in the Oyster Ground. This species is known to live as a commensal of the echinoid Brissopsis lyrifera (Ockelman, 1965). Indeed, B. lyrifera was found in two of the four samples too. We have inspected some older data and found that B. lyrifera was found in 1997 in combination with Montacuta spec. (Holtmann et al., 1998). A reidentification revealed that this was M. tenella. B. lyrifera was found at four stations in 2001. This indicates that the species occurs in increasing numbers in the Oyster Ground, which implies that M. tenella may also increase in abundance in this area. The gastropod Turbonilla pusilla was found at station OYS 38. The species also occurred at the Dogger Bank and in the offshore area. In previous years only empty shells of this species have been found. Completely new are the bivalve Gari costulata (found at OYS 17) and the gastropod Roxania utriculus (found at OYS 3). Both have, to our knowledge never been found on the DCS before. In spite of the relatively high number of new species in the Oyster Ground, there was no increased diversity in the area. The mean number of species per sample and the Shannon W iener index were within the range of values found in previous years. Also the total number of species (158) in the Oyster Ground was not particularly high compared to previous years (135 to 178). This is explained by the fact that there was a number of species that have been found now and then in previous years, but were not found in 2001. The absence of the latter species apparently neutralized the presence of the new species, so that the diversity did not change. Offshore area (Fig. 15a-c) The plots of the population densities o f 11 of the commonest species do not indicate that there were substantial changes in 2001. From 1995 onwards, there has been a slightly increasing trend in the sea urchin Echinocardium cordatum, but this increase has come to an end. The opposite holds for the gastropod Euspira nitida (formerly called Natica 13 Monitoring macrozoobenthos North Sea 2001 alderi): a decrease during the second half of the nineties and a recovery of population densities from 2000 onwards. The Offshore area had, as usual, the poorest benthic fauna. Total fauna densities, biomass and diversity were, like in previous years, the lowest in this area. In 2000, however, there was one station with a remarkably rich fauna, that was clearly different from all the other stations. This station (OFF 33), situated west of Umuiden, showed high densities of the crustacean Callianassa subterranea and the brittle star Amphiura chiajei and there were four mollusc species that were not or only very sparsely found alive before. It was suggested that the sample could have been taken close to a ship's wreck. In 2001 the station appeared to be very rich again. However, in spite of the high species richness (the sample contained 35 species), the species composition was not particularly different from that at the other stations. The gastropod Turbonilla pusilla was found at station OFF 11. It is remarkable that this species of which in 2001 for the first time living specimens were found, did occur at the Dogger Bank, the Oyster Ground and in the offshore area. Apparently, the species does not seem to have a specific preference for a particular sediment texture. Coastal area (Fig. 16a-c) In the coastal area there seemed to be a recovery of the population densities o f the gastropod Euspira nitida (= Natica alderi). This species had strongly decreased in 1992 and 1993 and occurred in very low numbers up to 2000. However, in 2001 the species returned at 5 stations. There was also an increase in the bivalve Tellina fabula. After a dip in 1996 and 1997 the species shows a steady increase up to 2001. The apparent increase in the densities of the bivalve Mysella bidentata is caused by the extremely high density at one station. At this station, COA 14, about 2000 individuals occurred per m". The other more or less abundant species did not show substantial differences with the preceding years. The densities of the polychaete Nephtys cirrosa were still at a low level. After a steep decline in 1996 this species has never reached its former densities. N. cirrosa is a species of sandy sediments and also occurs at the Dogger Bank and the offshore area. Since the species showed low densities also at the Dogger Bank and, to a lesser extent, in the offshore area, there seems to be a trend that covers the whole DCS. Like in previous years, high biomass values were found at stations where banks of bivalves occurred. Particularly high values were found at the stations COA 4, 9 and 12. The banks at these stations were formed by Spisula subtruncata and/or Ensis americanus. At stations where such banks were absent, the biomass values were generally low. For example, an extremely low value of 0.2 g AFDW per m2 was found at station COA 13, in front of the coast of Zeeland. 14 Monitoring macrozoobenthos North Sea 2001 6.
