OB24D:
Marine Deoxygenation in a Changing Climate: Drivers, Detection, and Ecosystem Impacts II Posters

Session ID#: 84415

Session Description:
Oxygen sustains life in the ocean and present observational evidence suggests its declining trend. Over the 21st century, with climate warming, Earth system models project continued deoxygenation and expanded oxygen minimum zones. This, in turn, could affect the cycling of nutrients and other chemical tracers, which could alter the biologically mediated carbon pump and feedback to climate system. Advancement in deoxygenation predictions as well as better understanding of its drivers, spatial extents, rates, and impact on ecosystem (functioning, service, biodiversity, etc.) are essential to develop future management and adaptation strategies in respond to changing marine ecosystem functions and resources. This session invites regional-to-global scale (i) observational and modeling contributions that elucidate the role of climate-induced changes in ocean’s physical and biogeochemical properties on the oxygen variability, (ii) novel model-data analysis approaches to determine the rates of and to provide early detection of oxygen changes, and (iii) studies that uncover evidence of past deoxygenation from paleo-proxies in elucidating its ecosystem impacts.
