1. Ocean acidification sessions at the EGU Meeting, Vienna, April 2011

There will be several ocean acidification sessions at the upcoming meeting of the European Geosciences Union (Vienna, 3-8 April 2011).
General information on the meeting is available here: http://meetings.copernicus.org/egu2011/.

The deadline for abstract submission is 10 January 2011. More information: http://tinyurl.com/3a74bqz

2. Abstracts are invited for session BG3.1: Ocean acidification and its impact on polar ecosystems of the EGU meeting, April 2011, Vienna.

Ocean acidity has increased by 30% since preindustrial times due to the uptake of anthropogenic CO2. It is projected to rise by another 100% by 2100 if CO2 emissions continue at current rates. Polar seas are considered to be particularly vulnerable to ocean acidification because the high solubility of CO2 in cold waters results in naturally low carbonate saturation states. CO2-induced acidification will make these waters undersaturated with respect to calcium carbonate and, therefore, corrosive for calcareous organisms. By the time atmospheric CO2 exceeds 490 parts per million (2040 to 2050, depending on the scenario considered), more than half of the Arctic Ocean is projected to be corrosive to aragonite.

Presentations from the EPOCA Svalbard experiments (2009 and 2010) are particularly welcome as are all contributions addressing ocean acidification in polar areas, including observations, experiments and modeling.

*********************************************
OS3.1 SOLAS/IMBER Special session. Sensitivity of marine ecosystems
and biogeochemical cycles to global change.

Achieving a quantitative understanding of the key biogeochemical-physical interactions and feedbacks between the ocean and the atmosphere and how marine biogeochemical cycles and ecosystems interact is a prerequisite to understand how this coupled system affects and is affected by climate and environmental change. Indeed attempts to predict the future global environment depend on a comprehensive understanding of how plankton biodiversity and biogeochemical cycling in the oceans affect the climate system, and of how changes in climate influence the structure and functional properties of oceanic ecosystems. This session calls for contributions related to experimental work at sea or in the laboratory, remote sensing studies, and modelling studies on the responses of key marine biogeochemical cycles, ecosystems and their interactions, to global change. Contributions dealing with exchange processes at the air-sea interface are also welcome.
