Climate Change in the Deep Sea: Impacts, Interventions, and Cumulative Stressors
Session ID#: 254879
Session Description:
The deep ocean provides 90% of the habitable space on Earth, and hosts high levels of biodiversity. The deep ocean is also the largest carbon reservoir on Earth. Yet, due to the sparse nature of observations and climate studies in the deep sea, low confidence surrounds numerous acutely important and policy-relevant issues. Based on an analysis of uncertainties relating to the deep sea in the IPCC AR6 reports, seven major areas of low confidence were identified: meridional overturning circulation, ocean carbon cycle, primary production and food supply, ocean deoxygenation and acidification, climate change impacts on ocean ecosystems, climate change impacts on fisheries, and ocean-based climate interventions. In preparation for the IPCC AR7 process, we invite submissions to this session on new studies that address these key areas of uncertainty, as well as other studies on how climate change is impacting and will impact the deep sea (defined as the region below 200 m depth). This Ocean Sciences Meeting presents a key window of opportunity to put emphasis on filling these important knowledge gaps before the deadline for considered publications for the IPCC AR7 reports.
