Size-fractionated zooplankton biomass and isotopes along the BC coast

This dataset contains size-fractionated zooplankton biomass and isotope data obtained from collecting samples with vertical net hauls by the Hakai Ocean Observing Program. The sample is poured through a series of sieves and filtered onto GF/F filters where weights are taken throughout the process to help determine the biomass prior to being sent for isotope analysis. These samples have been collected biweekly to monthly from 2015-2025 in the northern Strait of Georgia, British Columbia, approximately every 4-6 weeks 2012-2021 between Kwakshua Channel and Rivers Inlet, and the summers of 2015 and 2016 in Johnstone Strait on British Columbia's Central Coast.

This data package includes: - Size-fractionated biomass scaled to the volume of water filtered by the net - Size-fractionated stable isotope results and metadata - Tow metadata corresponding to samples collected

Data packages only include results that have gone through our metadata QC protocol. Users can reach out to request data not included and for collaborative opportunities.

Isotope Analysis done at the University of California Davis Stable Isotope Facility, at the Rhodes University IsoEnvironmental Facility, the Fisk Lab Stable Isotope Facility at the University of Windsor, and a Stable Isotope Lab in the Faculty of Forestry at the University of British Columbia.
