Abstract:

This dataset contains water column measurements made onboard the R/V Endeavor and R/V Weatherbird in May 2012 including temperature, salinity, dissolved oxygen, methane concentrations, del13C, and 14C of dissolved inorganic carbon (DIC).

Purpose:

The collection of this data was in support of identifying the methane concentration and petrocarbon in the water column.
