Upwelling Patterns off Portugalof the coastline which, associated with the nearshore deep features of the Lisboa and Setúbal canyons, apparently causes an offshore separation of the waters upwelled north of the Bay of Setfabal. South of Cape Sines, isotherms again tend to follow the depth contours, but thermal gradients are close

Oxygen isotopes of . document the temperature ranges of the upwelling seasons. The combined isotopic record of . white and . clearly reveals the latitudinal variations of seasonality and the annual mean SST, thus documenting the longterm position of upwelling

On Nutrient Variability and Sediments in Upwelling Regionsution off Peru, may be correlated with changes in the sediment make-up. Shorter term variability . may not leave a recognizable sedimentary imprint, but regions with well developed short-term variability may in general export more biogenic material to the sediments than less variable systems.

Seasonal Variation in Particulate Flux in an Offshore Area Adjacent to Coastal Upwellingpwelling occurs near the coast, colder water, possibly with higher nutrient levels, can be advected rapidly offshore in the form of surface plumes. Satellite images from April through July, 1981, reveal at least three plumes crossing our area during the period June 21-July 29. These cold water plume
