No Data Value:
 nd
Description:
 

Observation/sample depth below the sea surface. Units often reported as: meters, feet.

When used in a JGOFS/GLOBEC dataset the depth is a best estimate; usually but not always calculated from pressure; calculated either from CTD pressure using Fofonoff and Millard (1982; UNESCO Tech Paper #44) algorithm adjusted for 1980 equation of state for seawater (EOS80) or simply equivalent to nominal depth as recorded during sampling if CTD pressure was unavailable.

No Data Value: 
nd
Description: 

Depth of sample. Sea-water sample depths are reported as positive values. For sediment and borehole samples, elevation was set equal to the depth of the seafloor (all values negative) and depths into the seafloor are reported as positive values.
