HE009:
Particle dynamics and particle export in the polar ocean


Session ID#: 28597

Session Description:
Particles play very important roles in biogeochemical processes in the ocean. Yet particular matter and particle processes in the ocean are hugely under-sampled and under-characterized. This is especially true in the polar oceans, for biogenic, lithogenic and anthropogenic particles. Ongoing changes in the polar areas, with less sea ice, thawing permafrost and hydrological cycle intensification, can have dramatic effect on particle dynamics and particle fluxes. Quantifying any change related to these is difficult given the under-sampling.

We invite all investigations with relevance to particles in the polar oceans, be they conducted in the field, in the laboratory or by modelling approaches. We especially invite investigations dealing with erosion, river discharge and particle transport; primary production and cascade within ecosystems; the effects of wind and waves; the effects of fishery, offshore industry and coastal exploitation; the export from coast to shelf and from shelf to deep ocean; the export from the epipelagic to the meso and bathypelagic.
