-
The organic matter production/respiration balance in the coastal water column was
examined, both the primary production and community respiration being measured
with the oxygen light-and-dark bottle method. Community respiration (CR) was
always lower than the gross primary production (GPP) measured at a standard
light intensity of 390 μE m−2 s−1, which amounted, on average, to 30% of GPP.
During most of the in situ sampling period, the coastal system (6–7 m depth)
was found to be autotrophic, with depth-integrated GPP ranging from 6.7 mmoles
O2 m−2 d−1 in December to 214.2 mmoles O2 m−2 d−1 in August, and CR ranging
correspondingly from 6.0 to 177.7 mmoles O2 m−2 d−1. However, on some occasions
heterotrophic conditions were recorded: depth-integrated GPP
