Submit your abstract at the special sesssions n°99 and n°49 (details here below), at the ASLO AQUATIC SCIENCES MEETING - Nice, France, 25-30 January, 2009, http://aslo.org/meetings/nice2009/submittal.html, Abstract deadline 3 October, 2008
099. IPY-GEOTRACES : Trace Elements and Isotopes in Polar Oceans
Convenors: Marie Boye, LEMAR, IUEM, Technopole de Brest-Iroise, France, marie.boye@univ-brest.fr; H.J.W. De Baar, Department Ocean Ecosystems, University of Groningen, The Netherlands, debaar@nioz.nl
Trace elements essential for life, notably iron (Fe), play a key role in marine ecosystems and climate. Isotopes are natural tracers and time-clocks in the sea. The international GEOTRACES program has its flying start in the International Polar Year (2007-2008). The unique quasi-synopsis of IPY-cruises with GEOTRACES issues has the potential to provide new insights into a wide range of ocean processes and dynamics in Polar Oceans. Furthermore multi-tracers approaches and intercalibration exercises achieved during the IPY-GEOTRACES is an important step forward towards the development of analytical techniques that are essential to improve our knowledge of ocean dynamics.
049. The Southern Ocean during the International Polar Year
Convenors: Marie Boye, LEMAR CNRS UMR6539, FR, marie.boye@univ-brest.fr; Sabrina Speich, LPO, FR, speich@univ-brest.fr; Frank Dehairs, VUB, Belgium, fdehairs@vub.ac.be; Damien Cardinal, African Museum Tervuren, Belgium, damien.cardinal@africamuseum.be; François Lacan, LEGOS, FR, Francois.Lacan@legos.obs-mip.fr
In the framework of the IPY (GEOTRACES, ICED & CASO), BONUS-GOODHOPE programme aims at understanding the interactions between the oceanic dynamics, the bio- and geo-chemistry, the sediment and the atmosphere in the Southern Ocean and south-eastern Atlantic Ocean. The multidisciplinary and international MD166 BONUS-GOODHOPE cruise was conducted on board of the French R.V. MARION-DUFRESNE II between 33.58°S 17.14 °E and 57.33°S 00.02°W, from 08/02/07 to 08/03/24. A huge field work was achieved to collect samples and data in seawater (Niskin-CTD; GO-FLO, in situ pumps, underway pumping, XBTs, PROVOR, CPIES, incubations), in the atmosphere (balloons, dust and rain collection, sensors), and in the sediment (surficial multicorer). The unique complementary approach, based on the coupling of multitracers of selected trace elements and isotopes, with the biogeochemistry, the physical oceanography and the atmospheric dynamics, has the potential to provide unique insights into a wide range of oceanic processes and the status of the functioning of the Southern Ocean. Furthermore the synopticity with the German R.V. POLARSTERN (IPY ANT-XXIV/3 cruise) along the Greenwich meridian will bring a complete section of several parameters from the sub-tropical region towards the Antarctic Peninsula. We would like to report here the preliminary results of the BONUS-GOODHOPE cruise.
Furthermore international efforts to organise several Southern Ocean cruises in the framework of IPY have been successfully implemented in the last two years. Submission of abstracts presenting results from these cruises (e.g. SAZ-SENSE, Zero-Drake, SR3-GEOTRACES...) are particularly encouraged.
The first meeting will be held at Brest (at the European Institut of Sea Researches, IUEM, Amphi B), (see the access on the following web-link: http://www.univ-brest.fr/IUEM/contact/plan/plan_acces.htm) from monday 26, march until wednesday 28, march 2007.
