Abstract	Submarine canyons are heterogeneous environments known to support a variety of benthic organisms, and often considered biodiversity hotspots. Canyon morphological features facilitate the funneling of organic matter to the seabed, making them significant hubs of food resources for benthic life. In light of this, the DFFE: Oceans and Coasts initiative undertook the collection of benthic tissue data aimed at understanding how hydrography affects food availability for benthic species within and surrounding the Cape Canyon. This effort involved examining 15 stations, comprising six within the canyon and nine outside it, leading to the identification of six distinct trophic groups.
Methods	Samples were collected with an epi-benthic sampler (i.e., a customised dredge with a mouth opening of 30cm × 100cm and mesh-lining of 1cm2). To standardise sampling efforts, dredge transects had a bottom-time of 15 to 20 minutes and constant speed of 0.5 knots. Up to five individuals/specimens from each taxon were targeted, identified to the lowest possible taxonomic level, and dissected following Puccinelli et al's (2018) methodology.
