Dataset Overview | National Centers for Environmental Information (NCEI)

Dissolved inorganic carbon, total alkalinity, pH, and other variables collected from time series and profile observations using CTD, Niskin bottle, and other instruments near CenGOOS buoy off the coast of Mississippi in the Gulf of Mexico from 2012-10-15 to 2014-04-22 (NCEI Accession 0131199)

Preview graphic

This dataset contains time series profile (discrete bottle) data that were collected at the Central Gulf of Mexico Ocean Observing System (CenGOOS) buoy off the coast of Mississippi. The CenGOOS 3-m discus buoy serves as a platform for a NOAA/PMEL MAPCO2 system. Cruises are conducted on an approximately quarterly basis to take water samples for analyses to validate the MAPCO2 measurements. Water samples for DIC and Total Alkalinity and pH are sent to Wei-Jun Cai's lab at the University of Delaware for analyses.
