The exchange of CO2 and other gases across the ocean-air interface is an extremely
important component in global climate dynamics, photosynthesis and respiration, and the absorption of
anthropogenically produced CO2. The many different mechanisms and properties that control the air-sea
flux of CO2 can have large spatial and temporal variability, particularly in the coastal environment. The need
for making short-time-scale and small-spatial-scale estimates of gas transfer velocity, along with the physical
and chemical parameters that affect it, provided a framework for the field experiments of the Coastal Ocean
Processes Program (CoOP) Coastal Air-Sea Chemical Exchange (CASCEX) program. As such, the CASCEX
project provided an opportunity to develop some of the first in situ techniques to estimate gas fluxes using
micrometeorological and thermal imagery techniques. The results reported from the CASCEX experiments
represent the first step toward reconciling the indirect but widely accepted estimates of gas exchange with
these more direct, higher-resolution estimates over the coastal ocean. These results and the advances in
sensor technology initiated during the CASCEX project have opened up even larger regions of the global
ocean to investigation of gas exchange and its role in climate change.
