Abstract
Chlorophyll detected by Nimbus-7 CZCS satellite imagery was used to calculate the depth-integrated pigment content of the euphotic zone and this value was used in the global algorithm of Morel and Berthon to predict the annual production on the Grand Banks of Newfoundland. Physiological parameters were adjusted to take account of site-specific seasonal variation. Mean primary production computed from the algorithm was 194gCm−2 yr−1 which compared well with the mean shipboard measured value of 186gCm−2 −1. Production profiles by month show greater variation on the northern than on the southern Grand Banks.
