PC44B:
Ocean Heat and Carbon Uptake and Storage: Observations, Mechanisms, and Feedbacks III Posters


Session ID#: 11506

Session Description:
Heat and CO2 exchange between the atmosphere and ocean is a major control on Earth’s climate. Climbing atmospheric CO2 concentrations, along with associated radiative impacts, perturbs the ocean state and circulation. These physical changes in the ocean generally feedback positively on atmospheric CO2 levels by reducing ocean carbon uptake. However, the uptake of heat alters the circulation in ways that may feedback negatively (i.e. a stabilizing feedback) or positively on atmospheric warming trends. The sign and strength of these feedbacks depends on the complex interplay between physical and biogeochemical processes in the ocean and their interaction with atmospheric dynamics and radiative feedbacks. Recent advances in observational and modeling capabilities have deepened our understanding of these relevant processes. However the exact mechanisms governing the magnitude and regional distribution of heat and carbon uptake and storage remain poorly understood. This session seeks new and evolving insights into modeling and observational efforts that investigate all aspects of the ocean’s role in anthropogenic CO2 and heat uptake, storage and transport including the role of large-scale overturning circulation, water mass formation, ocean-ice-atmosphere, mixing, mesoscale and biogeochemical processes. We invite contributions that investigate ocean heat and carbon uptake, storage and transport on regional to global scales.
