Dataset: CTD_Cokelet eco FOCI cruises
Deployment: GP0207-01

CTD casts from surface to near-bottom were collected using a Sea-Bird SBE 25 CTD, Sea-Bird SBE 19 Seacat CTD, or Sea-Bird SBE 911plus Seacat CTD (see dataset-deployment metadata for specific model used on each cruise). Salinity samples were analyzed on shore with an AutoSal, and corrections were applied to the CTD-measured salinities. Chlorophyll-a was inferred from fluorescence by a linear least-squares fit of laboratory-measured chlorophyll extracted from water-bottle samples versus fluorescence measured at the same depth and time.

GP0207 and GP0201 are synonymous. The first is the GLOBEC descriptor, the second is the NOAA descriptor. The eventlog was submitted without a cruise-id, so data managers used the standard yy-mm descriptor. When NOAA submitted the data, the data had the GP0201 designation.

CTD casts from surface to near-bottom or about 200 m (whichever was shallower) were collected using a Sea-Bird SBE 19 Seacat CTD (conductivity-temperature-depth) profiler carrying single, pumped temperature, conductivity and chlorophyll fluorescence sensors. The CTD sampled at 2 Hz and was lowered at 20 m/minute.  Data were averaged into 1-decibar pressure bins.  Sea Bird gives the temperature and conductivity accuracy of 0.01 degrees C and 0.001 S/m, respectively.  On each cast, a Niskin bottle collected discrete water samples alternating between the shallowest and deepest sampling depths.
