| Summary: | No abstracts are to be cited without prior reference to the author.A suite of physical, chemical and biological variables are measured at stations along a section across the Labrador Sea between southern Labrador and southern Greenland once a year by scientists from the Bedford Institute of Oceanography. Satellite images of sea surface temperature and chlorophyll provide extended coverage over space and time. From 1990 until 2006 near-surface temperatures increased by about 1°C. Over the same period nitrate concentrations in the central basin increased, while silicate concentrations decreased. Total inorganic carbon concentrations, measured since the mid-1990s, increased and pH decreased. The phytoplankton community appeared to respond to these changes with an overall increase in spring/summer chlorophyll concentrations, but with changes in size/species composition. The zooplankton community did not show large changes in biomass or community composition. On the other hand, for Calanus finmarchicus, which ... |
