Benthic ecosystem functioning in the Arctic

Samples were collected during the Malina programme at 8 sites ranging in water depth from 47 m to 577 m in July and August 2009 onboard the icebreaker CCGS Amundsen. At each sampling station, an USNEL box corer (50 cm×50 cm×30 cm) was deployed for seafloor sediment collection. From each box core, 3 sub-cores of 10 cm diameter and approximately 20 cm sediment depth were taken for assessing benthic oxygen demand and nutrient remineralisation in microcosm incubations. Six additional sub-cores of 2.4 cm diameter were taken, three of 8 cm

and 1 cm length, respectively, for determining sediment pigment concentration, water content and sediment solid phase composition.

Purpose

The objective was to determine what drives spatial variation in benthic remineralisation function measured as benthic boundary fluxes in the Beaufort Sea/Mackenzie Shelf. We tackle our objective by addressing the following subjects: (1) ineffectiveness of oxygen flux as proxy for spatial patterns in benthic boundary fluxes; (2) timescales and distinct environmental forcings on

different biogeochemical fluxes; and (3) statistical modelling of benthic remineralisation function using environmental parameters.
