I am
IODP Science Steering and
Evaluation Panel (SSEP) delegate for
ECORD,
the European Consortium for Ocean Research Drilling, and
representing The Netherlands. SSEP is responsible for the scientific evaluation
of drilling proposals. Lucas Lourens
replaced me as ESSAC

Urbino Summerschool in Palaeoclimatology
Together with Simone Galeotti (Urbino), Stephen Schellenberg (San Diego) and
Roderik van der Wal (Utrecht), I am co-director of the International Summer School in Paleoclimatology
(USSP) held at the University of Urbino in Italy. The school focuses on teaching
young graduate students and other interested parties various aspects related to the multidisciplinary area of the paleoclimatic
reconstruction and modelling, with more than 50 internationally accliamed senior
scientists. Photos and

Professional Dinoflagellate Cyst Short Courses
Together with Martin Pearce (StatoilHydro), Martin Head (Brock University),
Joerg Pross (Frankfurt University), Jim Riding (BGS), and other colleagues I
organize 1-week professional dinoflagellate cyst short courses, emphasizing
taxonomy, ecology, biostratigraphy and palaeoecology in various locations around
the world. These courses are based on the early ones by Bill Evitt, Graham
Williams, Lew Stover and Sarah Damassa, and have been run in the new form since
1996. In recent years, courses were organized in Tuebingen, Germany (2004),

The Netherlands Academic Year
Prize, 'expedition greenhouseworld'.
In
2007, our joint team from the department of Biology, faculty of Sciences, and
the Earth Science department, faculty of Geosciences Utrecht University won the
prestigeous prize for the best translation of top science to a broad public,
with the project 'Expedition Greenhouseworld'. The 100,000 euro, plus
contributions from sponsors, was spent on the production of an instructive and
appealing
website and DVD, together with multi-media producer
ZCENE, and senior Polar
traveller Marc Cornelissen.
In 2008, the project culminated in taking the prize-winning highschool students
on an actual expedition to Svalbard. Check here to enjoy the
weblog.
WUN Palaeo-Arctic Climate and
Environmentes (pACE)
Together with WUN colleagues
from Penn State University, Southampton University, Leeds University, Sheffield
University, Oslo University, we have formed the
pACE-initiative,
studying ancient Arctic climates and Environments. In 2007, a first workshop was
held in Longyearbyen, Svalbard. Click here for clip and photos.
DARWIN Azolla Project
During
the Arctic Coring Expedition (ACEX) 302 of the Integrated Ocean Drilling Program
(IODP) unique central Arctic drill cores have been recovered from the Lomonosov
Ridge (Backman
et al., 2006; Brinkhuis et al., 2006).
Preliminary analyses of the laminated sediments has shown that enormous
quantities of the free floating, freshwater fern Azolla grew and
reproduced in situ in the mid Eocene (~48,5 Ma) Arctic Ocean for a period
of at least 800 kyrs. Additional cores taken during commercial coring in the
Arctic Basin and in the adjacent Nordic Seas have also been reported to contain
huge amounts of Azolla remains (Brinkhuis
et al., 2006).
Azolla
is a free floating aquatic fern, which nowadays can be found in freshwater
environments in temperate and tropical regions all over the world. It ranks
among the fastest growing plants on Earth and due to its association with the
nitrogen fixing cyanobacteria Anabaena azollae, it is independent of
extern organic nitrogen. In that way Azolla is not only known to fix huge
amounts of carbon, but as well to produce vast amounts of organic nitrogen. The
nutrient, which mainly limits the growth of Azolla, is phosphorous.
From the presence of the
Azolla blooms, covering the entire Arctic basin, interesting information
about the prevailing environmental conditions can be derived. Due to its
intolerance for saline water, its presence implies that at least the surface
waters must have been fresh during extended episodes. Furthermore, it is
believed that this event might have influenced global carbon, nitrogen and
phosphorus cycles. Notably, the Azolla event occurred precisely at the
transition from a Greenhouse to an Icehouse Earth.
From a biogeochemical cycling
as well as from a global climate change perspective we thus identify a strong
need for better constraining the capability of Azolla as a sink for
atmospheric CO2 in a fresh Eocene Arctic Ocean, and assess its
potential role as a regulator of regional and global nutrient cycles. For this
purpose we have set up the
Azolla Project, in the frame of The Netherlands
Darwin initiative.
