Description

This dataset includes nutrients, pigment concentrations, cell counts and composition, backscatter and spectral absorption coefficients for particles and phytoplankton.

Modification history:
30 March 2011:
Corrected time parameter (hhmm) caused by scripting error during conversion from Matlab to BCO-DMO

29 March 2011:
variable bbp700 upgraded to six decimal places from four to increase resolution

07 January 2011:
Four variables removed at P.I. request:
ap748; ap765; aph748; aph765
