A)
EXECUTIVE SUMMARY
Hydrographic Surveys Ltd. was instructed by Wicklow County Council, to undertake a combined
bathymetric survey, bottom sampling and side scan sonar survey at the dredging disposal site used
as part of EPA Dumping at Sea License S0002-01 off the coast of Arklow, County Wicklow.
Dredging took place between May 2014 and Sep 2014.
This survey fulfils requirements as set out in EPA Dumping at Sea License S0002-01.
The bathymetric survey results with contours were plotted to Chart Datum on and are shown for
the entire survey area in APPENDIX B: DRAWINGS Drawing No. PH17008_D01.
The sea bed indicates gradual gradient sloping seawards, from a minimum high of 4.7m in the
North-West corner to a maximum depth of 12.2m in the South-East corner of the survey area.
The Side Scan Sonar results and mosaic are shown in APPENDIX B: DRAWINGS Drawing No.

Several targets were selected from the side scan imagery however, none of the targets identified
appear to have any relation to the disposal pit.

SITE LOCATION & DESCRIPTION
Hydrographic Surveys Ltd. was instructed by Wicklow County Council, to undertake a combined
bathymetric survey, bottom sampling and side scan sonar survey at the dredging disposal site used
as part of EPA Dumping at Sea License S0002-01 off the coast of Arklow, County Wicklow.
The bathymetric survey, side scan survey and bottom sampling surveys were undertaken on the
18th & 19th of September 2017.
B.2)
SURVEY OBJECTIVES AND EXTENTS
The main objectives of the survey were as follows:
Establish seabed depth and profile in disposal pit and surrounding area
•
Aid in the location of possible obstructions on the sea bed.
•
Examine and determine sea bed sediments.

Based on the location of the original disposal pit, the bathymetric and side scan survey area
extended to limits 500m north and south and 250m east and west of the disposal pit.

METHODOLOGY
A full list of the equipment used on site is given in APPENDIX A: EQUIPMENT LIST AND SPECS.
C.1)
HORIZONTAL CONTROL
Horizontal control for the survey was provided by a Trimble DGPS receiver with broadcast
differential signal corrections from monitoring stations. The GPS signal interfaced to the Hypack
survey software for logging and for online navigation. The unit has a sub-metre horizontal
positioning accuracy. On-line transformation of WGS’84 Latitude and Longitude to Irish National
Grid (ING) took place within the survey programme. All plotting of data is to Irish National Grid.

site by the bar-check method. A bar check was undertaken prior to and on completion of the survey
and is archived in paper format. The sounder was interfaced with the dGPS via Hypack 2016 survey
software thereby providing a digital record with related position fixes.
Line spacing for the bathymetric survey within the dump site was at approximately 25m intervals,
Co

orientated perpendicular to the coastline, in accordance with the requirements of the survey.
All bathymetric levels were reduced to Chart Datum. Tidal variations were recorded at Arklow
Harbour using a Valeport Tidemaster vented tide gauge. Tidal height was recorded every 3 minutes
for the duration of the survey. Tidal heights were recorded at an established TBM and levels
reduced to the required datum, i.e. Chart Datum.
The location and results of the bathymetry survey are shown in APPENDIX A: DRAWINGS
Drawing No. PH17008_D01 and PH17008_D02.
C.3)
SIDE SCAN SURVEY
The side scan sonar survey was undertaken to identify any potential obstructions located on the
seabed surface. Sidescan sonar imaging was obtained using a C-Max digital, dual frequency
100/325kHz, sonar. Data was logged utilizing a rugged CM2 sonar transceiver connected to a PC
running Maxview acquisition software. The DGPS signal was interfaced in Maxview and Hypack
survey software.

ARKLOW DISPOSAL SITE – TWO YEAR MONITORING SURVEY
Survey lines were undertaken at 25m line intervals, running perpendicular to the coastline to
acquire a 100% data overlap and achieve maximum data resolution.
Processing was undertaken utilizing C Max View processing software and mosaics produced in
AutoCAD charts using Hypack survey software.
The results of the side scan survey are shown in APPENDIX A: DRAWINGS Drawing No.

The Samples were taken using a stainless steel Van Veen grab sampler. Once recovered the samples
were sealed in specialised sample pots and labelled accordingly.
A 1 kg sample from each of the 5 no. sample locations were preserved using a mixture of
formaldehyde (diluted) and borax (powder form) and sent via courier to APEM Laboratories for
benthic macroinvertebrate analysis. The benthic macro-invertebrate analysis results were released
on the 11th October 2017
2 no. 450ml pots (one plastic and one aluminium) were collected for each of the 5 no. sample
locations and sent via courier to RPS Laboratories for granulometry and sediment chemistry
analysis. The granulometry and sediment chemistry analysis results were released on 11th October

RESULTS
The survey results and interpretations are discussed below.
D.1)
BATHYMETRIC SURVEY RESULTS
The bathymetric survey results with contours were plotted to Chart Datum on and are shown for
the entire survey area in APPENDIX B: DRAWINGS Drawing No. PH17008_D01.
The sea bed indicates gradual gradient sloping seawards, from a minimum high of 4.7m in the
North-West corner to a maximum depth of 12.2m in the South-East corner of the survey area.
A comparison has been made between the current and the previous survey (August 2016). The
differences were gridded at a 3 x 3m spacing and are presented in Drawing No. PH17008_D04 as
coloured soundings. In general, there has been very little difference in seabed levels across the
whole survey area between August 2016 and September 2017. In some areas close to the disposal
ru
se
.
site there has been a slight deepening in seabed levels (average of 0.1m, maximum of 0.4m).

In addition to the contractual Drawing No. PH17008_D01, an extra drawing, Drawing No.
PH17008_D02, is included in this report. This displays the disposal pit at a scale of 1:500, and was
produced to assist in the comparison of previous 1:500 scale drawings of the pit.

SIDE SCAN SONAR SURVEY RESULTS

The Side Scan Sonar results and mosaic are shown in APPENDIX B: DRAWINGS Drawing No.
In general, the side scan results were very similar to the previous monitoring survey conducted in
August 2016. The side scan records were dominated by a light gold colour indicating a sandy
smooth sea bed. There were some small dark spots on the records, indicating small rocks/boulders.
The numerous side-scan profile lines were processed and a selected number were used to create
the final mosaic. Both the mosaic and identified targets were corrected for layback. Due to overlap
of the mosaic image when plotted, the identified target positions should be used for locating targets.
Several targets were selected from the side scan imagery however, none of the targets identified
appear to have any relation to the disposal pit.

Deviating Samples
Report No.: 17-65371-1
Customer Reference: Not Supplied
Customer Order No: P09990
Our policy on Deviating Samples and reference list of Holding Times applied can be supplied on request. These have been implemented in accordance with UKAS Policy on Deviating Samples (TPS63).
RPS is not responsible for the integrity of samples as received, unless RPS personnel performed the sampling, and it is possible that samples submitted may be declared to be deviating.
Where applicable the analysis method remains UKAS accredited, however results reported for a deviating sample may be invalid. The reason for a sample being declared to be deviating is indicated below.
Where no sampling date was supplied, samples have been declared to be deviating. However, if a date of sampling can be supplied, the results may be reissued with the deviating sample status removed.
Where the sample container used was unsuitable, the appropriate Holding Time was exceeded, or the sample is flagged as deviating for some other reason, re-sampling/re-submisson may be required.
