High-resolution ocean and atmosphere pCO2 time-series measurements from mooring CoastalLA_91W_30N in the Coastal Waters of Louisiana and Gulf of Mexico (NCEI Accession 0209137)

Preview graphic

This dataset includes chemical, meteorological, physical and time series data collected from Mooring CoastalLA_91W_30N in the Coastal Waters of Louisiana and Gulf of Mexico from 2017-07-14 to 2021-08-25. These data include air-sea difference - partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 - atmosphere, pCO2 - water, salinity, sea surface temperature, oxygen, pH on total scale, total chlorophyll, nephelometric turbidity unit and salinity-compensated dissolved oxygen. The Moored Autonomous pCO2 [MAPCO2 (trademark of NOAA)] instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter. The Global CO2 Time-series and Moorings Project involves international groups from 18 countries who have mounted sensors on moored buoys to provide high resolution time-series measurements of atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). The CO2 Time-series and Moorings Project is coordinated by UNESCO International Ocean Carbon Coordination Project (IOCCP). The coastal LA buoy is located in 20 m water depth on the Louisiana continental shelf. The northern Gulf of Mexico has extensive wetlands and supports high biological diversity and biomass of fish, shellfish, and sea birds. This region is also the largest zone of oxygen-depleted (or hypoxic) coastal waters in the United States, which makes this region a unique setting to track the combined impacts of ocean acidification (OA) and hypoxia on the biological system. Coastal LA was established in July 2017 in collaboration with Dr. Stephan Howden from the University of Southern Mississippi after being previously deployed off coastal Mississippi. The move to the new location provides better coordination with long-term hypoxia monitoring projects and more opportunities for leveraging research on both hypoxia and OA. The OA observations at coastal LA are supported by NOAA's Ocean Acidification Program and also leveraged by existing activities supported through the Louisiana Universities Marine Consortium (LUMCON) and the Gulf of Mexico Coastal Ocean Observing System (GCOOS).
