Vertical distribution patterns of copepods, chlorophyll, and production in northeastern Baffin Bay

High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species were Calanus finmarchicus, Calanus glacialis, and Calanus hyperboreus V and VI. Copepod layers consisting of C. finmarchi...

Description
Summary:High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species were Calanus finmarchicus, Calanus glacialis, and Calanus hyperboreus V and VI. Copepod layers consisting of C. finmarchicus and C. glacialis were commonly situated ≈3–4 m above the chlorophyll maximum in a depth region corresponding to the peak in the derived vertical profile of primary production. Calanus hyperboreus V and VI coincided with the chlorophyll maximum. Estimates of daily copepod grazing rations based on daily primary production and the density of copepods, with the assumption of steady state, were ≈20% body C· d −1 .
