Parameter: CTD_sigma_t

Dataset: 
MOCNESS plankton composition and CTD data
Parameter: 
sigma-t
Master parameters information
Short Name:
 sigma_t
Short Description:
 sigma-t
Official Name:
 sigma-t
No Data Value:
 nd
Description:
 

Sigma-t density, often reported in kg/m^3 - 1000. 'Sigma-t' is density minus 1000 (without the effect of pressure). It is normally calculated from observations of temperature and salinity. (See How do we measure the density of sea water?)
