Book excerpt: Submarine canyons are some of the most prominent features of the world’s continental margins creating heterogeneity in the terrain, influencing local and global hydrodynamics and often creating hotspots of biodiversity, both on the seafloor and in the water column. Canyon morphology and location on the margin make them the main conduits between the shelf and the deep sea, focussing the transport of sediments, organic matter, nutrients, and increasingly pollutants and litter. The focus of this Research Topic is highlighting human connections to the deep sea. Previous studies have underlined the need for a better understanding of anthropogenic impacts on submarine canyons, and how they fast-track our human footprint to the deep sea. Besides a better assessment of the extent and nature of human activities in submarine canyons, it primarily requires a holistic understanding of submarine canyons as systems, governed by the interplay of geological, sedimentological, oceanographic and biological processes. The goal of this Research Topic, based on the recent INCISE2021 International Symposium on Submarine Canyons, aims to fill that gap by gathering the latest observations of human activities in submarine canyons, the latest insights in submarine canyon functioning, and the latest interpretations on how the two are influencing each other.
