| Summary: | No abstracts are to be cited without prior reference to the author.Deep basins in the Gulf of Maine act as refuge for a large population of diapausing Calanus finmarchicus during the summer and fall. The current paradigm suggests that this population acts as the primary seed population for Georges Bank in the Spring. Dynamics of the summer-fall population are not well understood however and loss terms from advection and starvation may be large. Observations of the diapausing population during 2001-2002 show strong population growth through the summer followed by a steep decline in animal density through January 2002. To assess energetic limitations and loss from the Gulf of Maine basins a new nitrogen specific respiration model has been developed for the resting stage of C. finmarchicus. Stage CV C. finmarchicus were collected during July and September 2003 from Wilkinson and Georges Basins using a MOCNESS and zooplankton samplers on the Johnson Sea Link II submersible. Metabolic rates were measured using a ... |
