, 2022 Deep-water settings represent one of the most poorly understood sedimentary environments, largely due to a lack of direct observations from modern systems. Technological advancements have recently enabled high-resolution seafloor mapping and water column monitoring that have incited interest in supercritical (Froude number >1) flow dynamics ...
