Última Phytoplankton chlorophyll a distribution and water column stability in the central Atlantic Ocean ArchiMer Agusti, S; Duarte, Cm. The relationship between the vertical distribution of phytoplankton chlorophyll a and the physical structure of the upper central Atlantic Ocean was investigated based on results from a cruise across the tropical Atlantic (27 degrees N to 36 degrees S). The thermocline was very sharp and shallow in the northern part of the transect, off the coast of Mauritania and Senegal, and deepened progressively to reach > 150 m deep between 20 degrees S and 30 degrees S. There was a deep chl a maximum associated with the thermocline throughout the transect, reaching chl a concentrations up to 50 fold greater than those in surface waters. The chl a concentration was greatest off the NW African coast and declined towards the south, parallel to a progressive deepening...

A study was conducted to assess the annual variability in planktonic metabolism and dissolved organic carbon (DOC) utilization in an oligotrophic Mediterranean Bay (Bay of Palma, Spain) and to test the role of elevated DOC concentrations in driving planktonic metabolism off balance. We examined, at monthly intervals over 17 mo, gross primary production (GPP), community respiration (R), net community production (NCP), DOC concentration, total chlorophyll a (chl a) concentration, and, for a smaller subset of 11 to 14 mo, net DOC fluxes, bacterial abundance (BA) and bacterial respiration (BR). The community was net heterotrophic in autumn, winter and the first summer studied, and shifted to net autotrophic towards the end of the study period. This period of...
