Since the beginning of the 1990's a number of global tracer data sets have been collected, along with global CO2 data sets. These data sets are increasingly being used, frequently in multi-tracer studies, to gain new insight into ocean circulation, water mass transformation processes and rates, and uptake of CO2 by the ocean. This session will highlight new directions of tracer applications in oceanography and ocean carbon studies. Specific topics considered for presentation include: (1) The use of observations in model simulations of ocean circulation and carbon fluxes, (2) The penetration of anthropogenic signals from the surface into the interior of the ocean (locations of fast communication between the surface and the interior, time scales for surface - deep ocean exchange, exchange rates, use of tracers to constrain the problem), (3) Variability of ocean circulation and carbon uptake rates (time scales of variability, methods to observe the phenomenon, model simulations and comparison to observations), (4) observing system design for tracers and carbon (is the repeat hydro section design adequate?), (5) New results from CLIVAR/Carbon repeat lines, and (6) Dissolved oxygen variability and change in the ocean. We encourage contributions addressing the topics listed above using single- or multi-tracer analyses, as well as conceptual or numerical models on local to global scales with emphasis on studies that apply tracers to the problem of anthropogenic CO2 uptake.
