Physical, chemical and biological oceanographic data collected in Douglas Channel and the approaches to Kitimat, October 2014-July 2015 / C.A. Wright ... [et al.]. : Fs97-16/200E

"Water, phytoplankton, zooplankton and sediment samples were collected in the Kitimat fjord system in October 2014, March 2015 and July 2015, during the second year of a 2013-2016 research programme funded by the federal government's World Class Prevention, Preparedness and Response for Oil Spills from Ships Initiative. Five instrumented moorings were deployed for a year, one in southeastern Hecate Strait and four in the Kitimat fjord system. All the moorings included sensors to measure temperature, salinity, current and oxygen. At two of the sites (HEC1 in Hecate Strait and FOC1 in Douglas Channel), Baker sediment traps were also deployed at 50 m depth, collecting sinking particles at 12-day intervals over July 2014-July 2015. The moorings with sediment traps also included chlorophyll fluorescence sensors just below the traps. Water column profiles of temperature, salinity, oxygen, transmissivity and fluorescence were collected electronically at various stations during each cruise. Water samples collected at the same stations were analyzed for dissolved oxygen, nutrients, salinity, dissolved inorganic carbon, alkalinity, dissolved organic carbon, coloured dissolved organic matter and oxygen stable isotopes. Turbidity and particle concentration were measured in surface water, and sediment grab samples were collected at a subset of the stations."--Abstract.
