The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Marine zooplankton comprise a phylogenetically and functionally diverse assemblage of
protistan and metazoan consumers that occupy multiple trophic levels in pelagic food webs …

We investigated the seasonal vertical migration of seven dominant arctic copepod species
from October 2007 to July 2008 in Amundsen Gulf. The large herbivore Calanus …

The reduction of sea ice in the Arctic Ocean, which has progressed more rapidly than
previously predicted, has the potential to cause multiple environmental stresses, including …

Zooplankton carcasses are ubiquitous in marine and freshwater systems, implicating the
importance of non-predatory mortality, but both are often overlooked in ecological studies …

During a research cruise to the Arctic Ocean in January 2012, we observed high occurrence
of carcasses of Calanus spp. We analysed live samples to separate living from dead …

We report results from a yearlong, moored sediment trap in the Amundsen Sea Polynya
(ASP), the first such time series in this remote and productive ecosystem. Results are …

Zooplankton carcasses are an important, yet understudied, pathway of the biological
gravitational pump. To understand their contribution to the downward carbon flux in the …

Viruses infect all living organisms, but the viruses of most marine animals are largely
unknown. Crustacean zooplankton are a functional lynchpin in marine food webs, but very …

Recent observations from high-latitude marine ecosystems indicate that non-consumptive
mortality may be particularly high in Arctic zooplankton during the polar night. Here we have …
