INQUA - SACCOM COMMISSION, President’s Report 2015 SACCOM Mission The Stratigraphy and Geochronology Commission of the International Union for Quaternary Research (INQUA – SACCOM) is devoted to the study of the Quaternary Period through Quaternary stratigraphy and chronology. It provides a forum for Quaternary scientists to discuss and establish stratigraphical investigations and classification throughout the World. It seeks to achieve this through the organisation of regular meetings, publications and publicity. In addition a network of groups with specific mandates are established under the auspices of the Commission. SACCOM Officers President: Philip L. Gibbard, University of Cambridge, England.

Brief summary of activities during reporting year This grant, originally provided in 2013 for a tephra meeting to be held in Chile-Argentina (which was subsequently postponed), was carried over to 2014 (see letter from Koji Okumura and Phil Gibbard dated 14 April 2014) to support a skills-enhancement focussed workshop “Tephra 2014: maximizing the potential of tephra for multidisciplinary science” that ran from 3 to 7 August, 2014, in Portland, Oregon, USA. The “Tephra 2014” workshop, which involved a 1-day field trip, 2 days of papers, and a day of discussions, was organized by Steve Kuehn (Concord University, USA), Marcus Bursik, and Solene Pouget (University at Buffalo, USA). The workshop was convened to discuss major developments best practices and future directions/needs in tephra studies from both volcanological and tephrochronological perspectives. During three days of presentation and discussion, tephra scientists discussed challenges, opportunities and solutions in studies ranging from physical volcanology to archaeology. 6.

Aims and activities, to be included in Quaternary Perspectives The International focus group on tephrochronology and volcanism (INTAV) has three broad aims: (1) to improve the methodologies of tephrochronology and thus, through chronostratigraphy, support and underpin Quaternary projects (such as CELL50K, TRACE, SMART, INTIMATE), (2) to enhance volcanological applications through tephrostratigraphy, tephrochronometry, and petrological studies, and (3) to maintain and extend the capability of the discipline and to promulgate its value to the wider community, both scientific and layperson. INTAV members are working towards these aims via a series of 7 objectives that form the basis of the INTREPID Tephra – II project “Enhancing tephrochronology as a global research tool through improved fingerprinting and correlation techniques and uncertainty modelling (phase II)”, as follows. Objective (1) To evaluate and apply new and emerging technologies to: (a) identify and map proximal-to-distal tephras and cryptotephra deposits (i.e., at a full range of scales); (b) to establish their spatial and stratigraphic interrelationships; (c) to improve understanding of the environmental data preserved in the morphology and distribution of tephra and crypotephra deposits; (d) to facilitate their use as chronostratigraphic units (including developing the use of tephrochronology in cross-scale analysis); and (e) as a basis for documenting volcanic eruption histories. Objective (2) To develop and evaluate new and emerging methods to characterize tephra and cryptotephra constituents mineralogically and geochemically (including isotopically) using formalised protocols that enhance data quality and quantity. Objective (3) To develop and apply improved age models for tephra and cryptotepha deposits. Objective (4) To evaluate and develop objective ways of correlating tephra and cryptotephra deposits from place to places using statistical techniques and numerical measures of (un)certainty of correlation. Objective (5) To develop regional databases (using a uniform global framework) of high-quality mineral, geochemical, and other data (stratigraphic, chronologic, spatial) for tephra and cryptotephra deposits. Objective (6) To maintain and enhance the global capability of tephrochronology for future research through mentoring and training of emerging researchers in the discipline. Objective (7) To improve education to the wider community (outreach) about tephrochronology and its application and relevance. Thus the Tephra 2014 Workshop provided great impetus to helping to attain these objectives, with emphasis on objectives (1), (2) (4), (5), and (6). Previously, little emphasis has been placed on (5) in particular (databases), and so the workshop has provided an exceptionally important lead in helping to develop this aspect of tephra studies. The development of emerging researchers (objective 6) is also seen as a key requirement for INTAV, and the mix of veteran tephrochronologists (Westgate, Sarna-Wojicki) together with emerging researchers provided an ideal opportunity for mentoring and training the next generation of tephrochronologists. 9.

ACCOMPLISHMENTS DURING REPORT YEAR 1) SEQS2014 annual meeting The Quaternary of the Urals: Global trends and Pan-European Quaternary records was the central theme for the 2014 annual meeting of SEQS which took place from 10-16 September 2014, in Ekaterinburg, Russia. There were 78 participants and amongst them an encouraging number of relative young researchers. In two day of lecturing 34 oral and 38 poster presentations were given. The regional Quaternary stratigraphy at the eastern most boundary of Europe was discussed during the pre- en post conference excursions. A full report of the meeting is attached to this report and can also be found on the SEQS website (www.inqua-seqs.org). The book of abstracts and excursion information can be found on the publications page of the SEQS website (http://www.inqua-seqs.org/publications/). 2) Workshop framing EU Quaternary stratigraphy. The workshop took place from 13-14 December in Vienna. There were 12 participants, each representing a country. All participants are experts on Quaternary stratigraphy for their region. Originally the workshop was planned concurrently with the annual meeting but due to complicated time schedules it was decided to postpone the workshop to the end of 2015. The main aim of the workshop was bringing together existing and new data on Europe’s Quaternary in order to establish a new stratigraphical framework for the Quaternary terrestrial deposits in Europe. Basically the compilation is described along a section across the European continent running from the Atlantic seaboard to the Urals. The result of the workshop are being summarised in the first half of 2015 and will be presented at session SA3, during the INQUA congress in Nagoya, Japan. 3) Proceedings SEQS 2013 The proceedings of the SEQS2013 meeting in Constanta (RO) will be published in a special issue of Quaternary International. The volume was nearly finished by the end of 2014. Guest-editors are the organisers of the meeting, Silviu Radan, Nicolae Panin & Sorion-Corneliu Radan. All from GeoEcoMar in Bucharest (RO). 8. LIST OF PUBLICATIONS DURING REPORTING YEAR Publications will appear in the QI special issue of SEQS2013 9. AIMS AND ACTIVITIES, TO BE INCLUDED IN QUATERNARY PERSPECTIVES. SEQS- Section on European Quaternary stratigraphy (rationale and aims) The Quaternary stratigraphy in Europe has been developed over the last 150 years. Initially deposits were differentiated based mainly on rock properties and geomorphological characteristics. Already soon biogeological evidence from plant macro-remains and the fossil remains of small and large mammals were added. Halfway the last century detailed pollen-based subdivisions in stages and substages came into existence. Applications of the 14C method and luminescence dating have added absolute ages for the last 40 Ka and respectively 150 Ka. Palaeomagnetic ages are locally available but due to the fragmentary character of Quaternary continental deposits a well-constrained sequence that spans the full Quaternary is lacking. Furthermore one has to realise that the European Quaternary sequences are not evenly distributed throughout the continent. There are marked regional differences. In brief: the Early Quaternary is relatively well-recorded in and around the North Sea. Mid-Pleistocene sequences seem to be best developed in the Central European plains and southward of the maximum land ice advances. The Alpine glaciation history is traditionally best-studied in the Alpine Foreland while the northern ice sheets left major deposits on the North European Lowlands. Loess covers are widely spread in Central and Eastern Europe and have registered mainly Mid- to Late Pleistocene developments. In addition several parts of the Quaternary geological history are recorded in fluvial systems either by the infill of sedimentary basins or in regionally developed stair cases of fluvial terraces. So, Quaternary stratigraphy in Europe deals with regional and local different stratigraphical schemes derived from a variety of depositional systems. Nevertheless, the available European records provide a huge source of information on climate change and its impact on Earth surface processes. By careful and thorough evaluation SEQS attempts to establish a cross-continental understanding of local and regional developed stratigraphical concepts. The main aim is to develop and up-to-date maintenance a firm stratigraphical framework that serves as guidance for correlation across the European continent, from the Atlantic seaboard to the Urals. Terrestrial deposits and sequences thereby form a special area of interest. Their innate fragmentarily composition and the lack of absolute dating methods for the larger part of the Quaternary hampers a simple and straightforward solution. Through its activities SEQS also provides an important platform of exchange of stratigraphical knowledge and discussion of new developments. The achievements of SEQS form a perfect base to continue the work and activities in years following 2015. Providing a state of the art on the stratigraphical knowledge of Europe and formulating main research questions on the topic may help to introduce young scientists to get involved in future stratigraphical research. Project: Glacial History of Dinaric Alps DIG – 1st Workshop on DInaric Glaciation: Early/Middle Pleistocene glaciations of NE Mediterranean – filling the gaps in reconstructing its geological history and climate change” that took place in Starigrad-Paklenica in May 2013, was an initiative to involve an international team for further research of the hypothesized extensive Dinaric glaciation and the Quaternary stratigraphy and chronology in Croatia. The Workshop was supported by the Commission onStratigraphy and Chronology and received financial support under category Skills Enhancement. Besides leaders, five senior scientists and six early-career researchers (PhD and Master students) participated in the Workshop, although at least twenty have been expected. This “pilot project” proposal is a follow up with a goal to team-up researchers from all countries of Dinaric Alps and propose/formalize an International focus group for the intercongress period 20152020. Following the conclusions of the Workshop, the 2nd DIG Workshop will take place in Starigrad-Paklenica in May 2014, and annual workshops are planned for the next 3 years. A contribution to this project will also be the 4th Scientific meeting “Geology of Quaternary in Croatia” with international participation that will take place in Zagreb in March 2015, which will attract more researchers to join the focus group.

Brief summary of activities during reporting year As the main part of the Project, the 2nd DIG Workshop was held in May 2014, and repeated in October with 14 participants in total, including five senior scientists from Denmark, Norway, Poland and Croatia, and two doctoral students, three master students and four bachelor students, all from Croatia). Workshop days: Introductory lectures on regional geology and glacigenic sediments were given by workshop leaders, and all participants were engaged in discussion. All four days were spent in the field observing and discussing the following topics: regional geology and glacial sediments in the Velika Paklenica Canyon, Novigrad Sea coastal section - focus on transitional sedimentary successions (glacial-proglacial-periglacial-interglacial), observation from a boat of the lateral and vertical facies transition along the 3 km long coastal section of the Novigrad Sea, glacio-deltaic succession of Seline section, and glacilacustrine sediments of Novigrad, Karin and Zdrilo with Pleistocene macroflora and evidence of glaciotectonics. Workshop conclusions: The field discussion was especially useful for students and young researchers. Participation in this Workshop was crucial for few of the bachelor students to decide to take Master programme in geology, Quaternary in particular. New contacts were made for further studies and project elaboration. 6. Summary of accomplishments during report year Dissemination of knowledge about glaciation of the Dinaric Alps by showing type localities and onsite discussions about glacigenic sediments and processes, as well as engagements of graduate and postgraduate students in Quaternary research, represent major accomplishments of this ongoing project. New connections with other researchers and motivation of students lead to new project proposals for extended research of the Dinarides. Unfortunately, there was no financial aid on national level in 2014 to support the rest of planned project activities. 7. List of publications during reporting year DIG – 1st Workshop on DInaric Glaciation: Early/Middle Pleistocene glaciations of NE Mediterranean - 1306S and Glacial History of Dinaric Alps – 1411/ Report by Ljerka Marjanac / Quaternary Perspectives 21(2)-2014 DIG Workshop Guidebook 8. Aims and activities, to be included in Quaternary Perspectives. Glacial history of Dinaric Alps, the Croatian Dinarides in particular, is mainly based on sedimentological evidence documenting a significant extent of glaciation, and several U-series dates setting the major glacial advance in time of the Middle Pleistocene. Therefore, the aim of a series of dedicated yearly workshops (“DIG – Workshop on Dinaric Glaciation: Early/Middle Pleistocene glaciations of NE Mediterranean – filling the gaps in reconstructing its geological history and climate change” from 2013 onwards) is to show and discuss sedimentological evidence within broad scientific community dealing with Quaternary issues of global interest, especially past and future climate and environments. Other activities include networking of researchers from Dinaric Alps countries and other experts working on relevant topics, creation of DIG website with continuous updating, elaboration of a list of palaeo-glacial geoheritage sites, promotion of Quaternary geology. ICS-SQS activities 1. The Subcommission on Quaternary Stratigraphy (SQS) of the International Commission on Stratigraphy (ICS) has continued to work actively on several topics concerned with the formalisation of the division of Quaternary time. This year a marked effort was placed on the divisions to be proposed for subdividing the Holocene. The working group responsible is lead by Professor Mike Walker and includes a group of active Holocene workers from around the world. A second working group is focused on the possible definition of a formal division to be termed 'Anthropocene'. This group has been very active during 2014, having produced a series of articles and a book on the Stratigraphy of the Anthropocene. The group also held a very effective meeting in Berlin in September 2014. This group is chaired by Dr Jan Zalasiewicz. During the year, the latest version of the Quaternary chronostratigraphical chart was posted for free download on the SQS website. The chart is regularly updated and produced by P.Gibbard and K.M.Cohen. SQS President is Professor Martin Head (Brock University, Canada). Details of all the activities of SQS are available on the website: Quaternary.stratigraphy.org 2. Field Workshop on the Lower–Middle Pleistocene transition in Italy (AIQUA, INQUA-SACCOM, ICS Subcommission on Quaternary Stratigraphy joint meeting) Workshop at Bari, 11th October,2014; Field trip 12th–13th October, 2014. Led by Neri Ciaranfi (1) & Martin J. Head (2) (1) – Dipartimento di Scienze della Terra e Geoambientali, Università degli Studi “Aldo Moro”, Bari, Italy (2) – Department of Earth Sciences, Brock University, St. Catharines, Ontario, Canada The field workshop meting on the Lower–Middle Pleistocene transition in Italy was organised by AIQua (Associazione Italiana per lo studio del Quaternario), sponsored by INQUA-SACCOM and the International Subcommission on Quaternary Stratigraphy, and supported by the Department of Earth & Geoenvironmental Sciences of the University “Aldo Moro” in Bari, Italy. The workshop presented the latest multidisciplinary studies on two Italian marine sequences, Montalbano Jonico in Basilicata and the Valle di Manche in Calabria, both candidates for the Middle Pleistocene Subseries global boundary stratotype section and point (GSSP). A presentation on a third GSSP candidate (the Chiba section in Japan) was also given. Two significant Lower– Middle Pleistocene lacustrine intra-penninic successions, San Lorenzo in the Sant’Arcangelo Basin (south Italy) and the Sulmona Basin (central Italy), were also discussed. A two-day field excursion included visits to Montalbano Jonico and the Valle di Manche, and also to the lacustrine deposits of the Sant’Arcangelo Basin. The following comments about the state of the studies on the two Italian candidate GSSP sections arising from this meeting are as follows: The Ideale section at Montalbano Jonico has detailed foraminiferal and nannofossil biostratigraphy, robust paleoclimatic data based on pollen and ostracods, δ18O isotope stratigraphy clearly identifying Marine Isotope Stage (MIS) 19 and its substages (19.1, 19.2, 19.3), astronomical calibration, and nine tephra layers (V1–V9) of which all are geochemically characterized and two (V3, V4) 39Ar/40Ar dated. Furthermore, the lower part of the Montalbano Jonico section together with the Vrica section in Calabria potentially represent a Unit Stratotype for the Calabrian Stage (e.g. see Cita et al., 2012). The good preservation of the section and its easy access are guaranteed by its inclusion within a 'Special Natural Reserve of the Montalbano Jonico Badlands' instituted under Law 3/11 of the Basilicata Region. The Valle di Manche section clearly shows the Matuyama–Brunhes reversal just below the peak of MIS 19, and has detailed foraminifer and nannofossil biostratigraphy, pollen ecostratigraphy, palaeoclimatic data, δ18O stratigraphy, and good chronology around the M–B boundary. It also has good exposure and good access, and the Pitagora Ash, which is close to the M–B boundary, provides a convenient local marker bed. The two lacustrine sections of San Lorenzo and Sulmona can be easily correlated to the Montalbano Jonico section by means of their well-dated tephra layers and through palynological assemblages.
