Time-series bathymetry of the northern Chandeleur Islands, Louisiana
Interannual time-series of bathymetry data showing infilling of a borrow pit created at the northern end of the Chandeleur Islands in 2010. Bathymetry shows seafloor depth, with red representing shallow water and blue representing deeper water. Sediment originally removed from the borrow pit was placed as a sand berm along the island platform and has been redistributed over the last several years. Using these data, we can estimate modern sediment fluxes and variations in those fluxes year-to-year, helping guide models and coastal restoration planning.
