This dataset was collected under the project entitled 'How do deep-ocean turbidity currents behave that form the largest sediment accumulations on Earth?', funded by Natural Environment Research Council (NERC) parent and child grants NE/R001952/1 and NE/R001960/1, with the former parent grant led by Professor Peter Talling, Durham University, and the latter child grant led by Professor Daniel Parsons, University of Hull. Also NERC grant NE/S010068/1 led by Professor Peter Talling. This grant is a second grant awarded to the end of NE/R001952/1 allowing for 3 more cruises. The aim is to improve understanding of turbidity currents, and their wider impacts, by making the first detailed measurements of turbidity currents that runout into the deep (2-5 km) ocean. Data were collected on James Cook cruise JC187 between August and October 2019, and moorings recovered during James Cook cruise JC209 between September and October 2020. Eight moorings were deployed along the Congo Canyon at water depths of 2 to 5 km to measure frequency, duration, and run-out distance of multiple flows; together with their velocity, turbulence and sediment concentration structures; as well as changes in water, sediment and organic carbon discharge. Further cruises are planned and will add to this dataset in the future, details will be included when available.
