Seasonal diversity & behaviour of internal tidal bores revealed by year-long direct monitoring within a submarine canyon: implications for particulate transport

Submarine canyons are the primary conduits for particulate transport from the continents to the deep sea, including sediments, organic carbon, and pollutants. Previously, focus has primarily been on transport due to downslope gravity currents. There is increasing recognition of the role internal tides may play, however, a lack of long-term seabed monitoring limits understanding of their significance. Here, we present novel near-seafloor monitoring data of breaking internal tides (‘bores’), spann
