PO14F:
Ocean Circulation and Biogeochemistry in a Water Mass Framework II Posters
Session ID#: 11460
Session Description:
Water masses are the phenomenological expression of large-scale dynamical processes in the ocean, and for this reason have long been the foundation of our characterization and understanding of large-scale ocean circulation. Recent and ongoing advances have focused on dynamically-active tracers (e.g. density, temperature, salinity and potential vorticity), as these lend themselves most directly to characterizing the budgets of heat and freshwater and more generally the overturning circulation. In addition a water mass framework is general, and can provide insight into the dynamical and thermohaline controls on ocean biogeochemistry and the ocean carbon cycle.
Recently significant attention has been devoted to water mass modification processes (formation, erosion) occurring within the ocean interior, and connecting this to surface transformations and the large-scale overturning circulation. Additional efforts have begun to consider this for the case of ocean biogeochemistry as the concepts of interior ventilation and dynamical controls on preformed nutrients and carbon are intrinsically linked to water mass formation processes in the ocean’s surface boundary layer.
This session welcomes studies that exploit in-situ and integrated observations, theory, and numerical modeling-based analysis (both Eulerian and Lagrangian). Abstracts are welcomed that focus on physical processes, biogeochemical processes and/or the interplay between the two.
