INQUA-NL Committee inter congress period 2008-2011

In July 2008, the INQUA-NL committee has reconsituted. Wim Hoek replaces Thijs van Kolfschoten (chair 2003-2007) as chair. Wim Westerhoff continues as secretary. Fred Janssen (NIOZ) has retired and Jos Deeben and Jan-Berend Stuut have joined.


Dutch scientists participate in organisatorial efforts to aid progress in Quaternary Research and to close gaps between disciplines, amongst others within INQUA commissions and subsommissions (restructured at the 2003 INQUA congress). In 2006-2008, dutch memberships of INQUA commissions were : Thijs van Kolfschoten (vice-chair Commission on Stratigraphy and Geochronology), Wim Hoek (secretary Palaeoclimate subcommision INTIMATE: Integration of Icecore, Marine and Terrestrial Records project), Jef Vandenberghe (Commission on Terrestrial Processes, Deposits and History), Jan-Berend Stuut (Palcom project PASH2) and Wim Westerhoff (secretary of SEQS: the Subcommission on European Quaternary Stratigraphy).

Dr. Kim M. Cohen (Utrecht University; Deltares)

Kim Cohen (1973) is employed at Utrecht University, Dept. of Physical Geography, where he studied and obtained his Ph.D. on Neotectonics in the Rhine-Meuse delta between 1993-2003. Kim Cohen has worked for the Max Planck Institute of Biogeochemistry (Jena, Germany) and was a visiting scholar of the University of Cambridge (U.K.) in 2003-2004. He returned to Utrecht University in 2005. Since 2008, he bridges between the Fac. of Geosciences and the national delta institute, Deltares, Dept. of Applied Geology and Geophysics and TNO Geological Survey of the Netherlands, working on sea level rise, river flooding, palaeo-groundwater rise and 3D subsurface mapping and dating.

Kim Cohen maintains this INQUA-NL website. Kim Cohen co-maintains the chart pages of the IUGS Subcommission on Quaternary Stratigraphy. Kim chairs the Sedimentological Circle of KNGMG (Royal Netherlands' association for professionals in applied and academic earth Sciences).

Interests include:

Jos Deeben (RCE)

Jos Deeben graduated in Human Geography in Nijmegen and Prehistory in Amsterdam. Therafter, he studied the transition from Late Palaeolithic to Mesolithic hunter-gatherers in the low countries (NWO 1988-1992; University of Amsterdam 1992-1995). Since 1995 he was employed as senior researcher at the National Archaeological Survey (ROB, now RCE, a.k.a. RACM inbetween). Since 2002 Deeben is Head of Archaeological Heritage at the National Service for Cultural Heritage (RCE).

Dr. Jan-Berend Stuut (NIOZ)

Jan-Berend Stuut (1971) is employed at the Royal Netherlands Institute for Sea Research (NIOZ) in the department of Marine Geology. Since his graduate studies in Utrecht University (1996) he has been trying to contribute to a better understanding of modern and past marine sedimentation processes, with main focus on aeolian-marine deposition. Being educated as a sedimentologist he is working with the physical, chemical and mineralogical properties of aeolian dust, both recent and dust found in sedimentary archives. In 2001 he received his PhD from Utrecht University and the Netherlands Institute for Sea Research in marine geology and sedimentology. Before returning to NIOZ in 2009 he worked for 7.5 years in Bremen, Germany at the MARUM - Center for Marine Environmental Sciences.

Jan-Berend has been actively participating in INQUA GA's since Durban, Reno and Cairns amongst others by organizing scientific sessions on aeolian dust and the environmental history of the southern-hemisphere. Since 2004 he co-chairs (with Peter Kershaw, Monash Univ., Melbourne, Australia) the Palcom project PASH2: "Land-Ocean correlation of long records from the Southern Hemisphere on orbital and sub-orbital timescales".

Interests include:

  • Main interest is climate-related sedimentation processes with special attention for aeolian dust.
  • The major approach is to study wind-blown sediments from source to sink.
  • Archives of aeolian dust: high-resolution Holocene sediment archives (sedimentation rates < 1m/kyr; both lacustrine and marine)
  • Late Quaternary marine sediment archives to reconstruct palaeoenvironmental conditions in the source areas of the sediments.
  • Present-day meteorological, physical, chemical, and mineralogical characteristics of dust source areas, and changes from source to sink(s).

  • Dynamics of fluvial systems:
    morphological, ecological and sedimentary processes and developments;
    mainly in relation to climate and climate changes.
