FOCI mooring ready for deployment in the Bering Sea aboard the NOAA Ship Oscar Dyson.  The M2 surface mooring that has been deployed each spring in the southeastern Bering Sea for over 25 years. This critical mooring provides year-round measurements of temperature, salinity, nitrite, chlorophyll, and currents in this highly productive area. For the last 10 years, partial pressure in CO2 (pCO2) and pH measurements have also been taken at M2.
