(2018). Benthic sediment and faunal sampling in outer Frobisher Bay. Waterloo, Canada: Canadian Cryospheric Information Network (CCIN). Unpublished data. In 2017 and 2018, we sampled about 20 locations across Frobisher Bay, mostly in the deeper portions of outer Frobisher Bay that are only accessible for sampling from large ships. Sample stations were chosen to span the range of depth and slope values in the multibeam sonar dataset, and in 2018 sampling, also included gross bottom morphology, such as ridges and troughs. We also targeted some particular geomorphic features, such as suspected submarine extensions of moraines. In 2017, bottom samples were acquired using box-cores, and small scientific trawl (Agassiz trawl). In 2018, bottom samples were acquired using box-cores, combined with a drop-video camera. Agassiz trawls were collected at two stations in 2018. Sediment samples were described visually and subsamples frozen for grain size and organic content analysis. Where informative, subsamples of lithic fragments within the sediments were kept for mapping. Bottom faunal samples were enumerated and preserved in 2% formalin in seawater, except for larger faunal samples such as soft corals, which were frozen. In order to construct a geological and biological habitat map of the deep outer parts of Frobisher Bay, we collected benthic samples from CCGS Amundsen in areas that had been previously mapped using multibeam sonar from the Amundsen. The benthic samples allow us to ground-truth the multibeam survey and classify bottom types and faunal assemblages.
