Seasonality and physical control of water properties and sinking and suspended particles in Douglas Channel, British Columbia / S.C. Johannessen, C.A. Wright, and D.J. Spear. : Fs97-18/308E-PDF
Water properties and particles in Douglas Channel were characterized during four cruises (July 2013, April, July and October 2014), and with moored sensors and sediment traps (July 2013-June 2014.) An outflowing surface layer 10-30 m thick, driven by Kitimat and Kemano River discharge, overlay a mid-depth layer that exchanged with Hecate Strait. Deep-water renewal in June increased the concentration of oxygen by 1 mL/L to 3.5 mL/L. The surface layer was turbid (beam attenuation coefficient ≤6 m-1). The sinking particle flux at 50 m was 438 g m-2yr-1,and the organic carbon flux 37 gC m-2yr-1. Fluxes of particles and organic carbon peaked in late May, during the river freshet. The concentration of organic carbon in the sinking particles was highest in August and September (12-13%), except for a single peak in mid-November (22%).
