Abstract

Maritime weather reports off SE Brazil are summarized to yield distributions of wind stress, Ekman transport, wind mixing index, insolation, cloud cover and sea surface temperature for 2-month segments of the seasonal cycle. Directly downstream of an upwelling center lies the coastal bight between Cabo Frio and Cabo Santa Marta Grande. The near-coastal water column within the bight while vertically homogeneous during winter, becomes stably stratified during summer. This coastal bight constitutes the primary reproductive habitat of the Brazilian sardine. Peak spawning activity during summer serves to place larvae into a stable, enriched environment, where they enjoy high likelihood of retention. -from Authors
