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 instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, oxygen meter and thermosalinographs. The Chesapeake Bay First Landing buoy was established in April 2018 in collaboration with NOAA Ocean Acidification Program (OAP), NOAA PMEL, U.S. IOOS Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS), and the University of Delaware (UDel) is to produce high quality data and models to monitor the Chesapeake Bay. The new buoy is located beside the First Landing Chesapeake Bay Interpretive Buoy System (CBIBS) site to maximize collaborations with existing research and observational efforts, leverage equipment assets, and integrate with ongoing ship-based surveys and outreach activities. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

Developed by Pacific Marine Environmental Laboratory and Monterey Bay Aquarium Research Institute, the h-shaped bubble equilibrator does not require a water pump to spray water from the top. see Takahashi 1961 for more information. carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water. oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. pH sensor pH sensor generic meter used to measure pH Any of a class of instruments used to quantify pH in a water or other type of sample. salinometer salinometer generic salinometer use salinometer when the instrument type used is unclear but the data include salinity measurements temperature sensor temperature sensor A sensor used to measure temperature. moorings entry created as MOORINGS OF UNITED STATES, but has been used as a generic MOORINGS entry.
