These data include WATER CTD TEMPERATURE, CTD SALINITY, DISSOLVED INORGANIC CARBON (DIC), TOTAL ALKALINITY (TA), CTD Dissolved OXYGEN, and nutrients (Nitrate, Nitrite, Phosphate, Silicate, and Ammonium). The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Arctic Research Program (ARP) and supported by numerous agencies and institutions including the National Science Foundation (NSF) and the Cooperative Institute for Climate, Ocean, and Ecosystem Studies. The Distributed Biological Observatory (DBO) is envisioned as a change detection array along a latitudinal gradient extending from the northern Bering Sea to the Barrow Arc. DBO sampling is focused on transects centered on locations of high productivity, biodiversity and rates of biological change.

NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. 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. CTD CTD Conductivity-Temperature-Depth probe nutrient autoanalyzer nutrient autoanalyzer Laboratory Instrument Nutrient Autoanalyzer is a generic term describing an automated flow-thru system used to conduct analyses of several different nutrients (nitrate, ammonium, orthophosphate, and silicate) simultaneously from a seawater sample.
