Submarine Fans: Turbidity Current Morphodynamics, their Deposits, and Impacts on Global Climate Change

Session ID#: 161325

Session Description:
Submarine fans form on continental slopes and abyssal plains in deepwater settings and are the ultimate sinks in sediment routing systems. They are crafted by turbidity currents, which arguably move more sediment on Earth than any other transport process and their deposits preserve the thickest accumulations of sediment on Earth. The surface dynamics that result in the formation of these fans influence the fidelity of climate change records housed in their strata, the frequency and severity of geohazards that threaten subsea infrastructures, voluminous geofluid reservoirs, management of marine litter such as microplastics, and burial of particulate organic carbon. We invite contributions that explore submarine fan morphodynamics through observations of the modern seafloor, preserved deposits imaged in outcrop or seismic, and/or that utilize numerical or geological models, and physical experiments.
