Abstract

Cruises were conducted in the vicinity of a meander east of 73°W and north of 37°N from September 21 to October 5 (leg 1) and October 12-21, 1988 (leg 2). Relationships of photosynthesis to irradiance (P-I) did not show large horizontal variation, and water column composite P-I curves from leg 1 and leg 2 were similar. Therefore a single P-I curve derived from pooled data was used to model distributions of primary production. Cross sections of the Gulf Stream revealed consistently higher pigment concentrations and primary production on the slope water side. Along-stream variations in pigment distributions and primary production were apparently related to density structure influenced by meander circulation. -from Authors
