American Society of Limnology and Oceanography (ASLO) Aquatic Sciences Meeting
Nice, France, 25-30 January, 2009

Two special sessions at the upcoming ASLO meeting that may be of interest to those involved with the International Polar Year.
Session titles are below, followed by a session summary.
 
Abstract deadline 3 October, 2008

Special session 099: IPY-GEOTRACES: Trace Elements and Isotopes in Polar Oceans

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.

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.
