Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:

Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.

Abstract:

Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...

Abstract:

Outcrops of old strata at the shelf edge resulting from erosive gravity‐driven flows have been globally described on continental margins. The reexposure of old strata allows for the reintroduction of aged organic carbon (OC), sequestered in marine sediments for thousands of years, into the modern carbon cycle. This pool of...
