The last BCCR Monday Seminar of the year will be given next Monday (December 15th) by Robert Pickart from the Woods Hole Oceanographic Institution. He will present his work on "Vertical carbon export during an under-ice phytoplankton bloom in the Chukchi Sea".

Abstract

In order to quantify pelagic-benthic coupling on high-latitude shelves it is imperative to identify the different physical mechanisms by which phytoplankton are exported to the sediments. In June-July 2023, a field program documented the evolution of an under-ice phytoplankton bloom on the northeast Chukchi shelf. Here we use in-situ data from the cruise, a simple numerical model, historical water column data, and ocean reanalysis fields to characterize the physical setting and describe the dynamically-driven vertical export of chlorophyll associated with the bloom.
