Накратко на български

Южният океан и конкретно субантарктичните води се изследват, за да се разбере как те абсорбират въглероден диоксид от атмосферата. Това помага за по-доброто разбиране на процесите, които смекчават последиците от климатичните промени.

Southern Ocean Carbon Uptake

The Southern Ocean is a disproportionately important region, relative to its size, for mitigating the consequences of the anthropogenic climate change, being responsible for 43% and 75% of the ocean uptake of anthropogenic CO2 and heat, respectively. The MSCA SO-CUP aims at shedding light on the processes underpinning the role of the Southern Ocean as a major sink of atmospheric carbon dioxide (CO2). Most of the heat and carbon uptake in the Southern Ocean is carried out by a group of water masses termed Sub-Antarctic Mode Waters (SAMW), which originate in deep surface mixing layers to the North of the Antarctic Circumpolar Current (ACC). As for most of the oceans’ water masses, SAMW properties are determined during winter, when large volumes of water are exposed to the atmosphere. However, the dynamical processes that control the formation of SAMW and the associated drawdown of carbon are not well understood due to the scarce data in this remote region during winter, which represents a critical bottleneck for the understanding of the current state and future evolution of the Southern Ocean carbon sink. The observational gap was significantly relieved in recent years, with the advent and large-scale deployment of autonomous technologies for ocean observation. Since 2014, the US SOCCOM program deployed in the Southern Ocean hundreds of autonomous profiling floats equipped with biogeochemical sensors, allowing for an unprecedentedly thorough observation of the Southern Ocean carbon cycle. The main scientific goal of the MSCA SO-CUP is to leverage the ongoing explosion in situ observations to identify and quantify the ventilation pathways and processes that govern the drawdown of atmospheric carbon by SAMW.

Цел на проекта

The Southern Ocean (SO) is a disproportionately important region, relative to its size, for mitigating the consequences of the anthropogenic climate change, being responsible for 43% and 75% of the ocean uptake of anthropogenic CO2 and heat, respectively. The Subantarctic Mode Water (SAMW) and Antarctic Intermediate Waters (AAIW) effect the bulk of this uptake. Yet the dynamical processes that control the formation of these water masses in the thick winter mixed layers to the north of the SubAntarctic Front (SAF), and the associated drawdown of carbon, are not well understood, primarily as a result of the scarcity of data during winter in this remote region. Hence, the present and future evolution of the SO carbon sink remains the subject of vigorous debate. The main goal of the SO-CUP project is to identify and quantify the processes that control the amount of inorganic carbon that is subducted with the SAMW/AAIW. To do so, the work plan integrates the use of recent in situ observations from biogeochemical Argo floats and a state-of-the-art data-assimilating, high-resolution coupled biogeochemical-physical ocean model (B-SOSE). Through analysis of these novel datasets, which allow for unprecedented data coverage of the SO in winter, the SO-CUP project will produce a major step forward toward understanding the ventilation and carbon uptake processes in the SO, and will help to predict their response to ongoing and future climatic changes. This proposal will also enable Dr. Fernández-Castro to decisively broaden his expertise on ocean physics and biogeochemistry, and to gain experience in the state-of-the-art technologies in these disciplines. These new skills and knowledge will propel Dr. Fernández-Castro’s career toward a status of independent scientist with high international visibility. Further, the SO-CUP project will establish new links between the EU and US communities for the investigation of the fundamental role of the SO in the climate system.
