Mesoscale and seasonal variability of community production and respiration in the surface waters of the N.E. Atlantic Ocean
Gross community production (GCP) and dark community respiration (DCR) rates were measured in the N.E. Atlantic Basin (38-451N and 15120 0-21120 0 W) during the Programme Oce´anographique Multidisciplinaire Me´so-Echelle (POMME). Three cruises were conducted over a one-year period (2001), and GCP and...

description |
Gross community production (GCP) and dark community respiration (DCR) rates were measured in the N.E. Atlantic Basin (38-451N and 15120 0-21120 0 W) during the Programme Oce´anographique Multidisciplinaire Me´so-Echelle (POMME). Three cruises were conducted over a one-year period (2001), and GCP and DCR were measured at 20 stations using seawater taken from 5 m. In winter, GCP is light limited whereas DCR, which is mainly due to bacteria, is limited by substrate availability. GCP and DCR were under the influence of mesoscale features, with the cyclonic structure enhancing the autotrophy. In spring, light and resource availability remain the major controlling parameters, which are constrained by north-south zonation, rather than mesoscale features. The most productive area is south of 411N at the start of the bloom and is associated with greater DCR as autotrophs contribute to community respiration. The late-summer period is oligotrophic, which contrasts with the previous winter and spring period, characterised by a large quantity of TOC accumulated (+13.2 mM C from spring to late-summer |
