Six scientists from PMEL are co-authors on a recently published report describing the 2nd decadal ocean survey to be completed as part of the US Repeat Hydrography CO2/Tracer Program. Beginning in 2003, scientists from OAR’s PMEL and AOML contributed to hydrographic surveys at 2,142 stations that cover full ocean depth in all ocean basins with physical and chemical measurements. For the first time, scientists can now compare two decades of measurements to track changes in ocean warming, circulation, acidity, oxygen concentrations and other properties.

PMEL Carbon, Ocean Tracer and Large Scale Ocean Physics programs were integral parts of the decadal survey.  Please visit the U.S. Ocean Carbon and Biogeochemistry website for the full report.
