This project is focused on the dredging impacts on the water quality and biogeochemical processes in two Louisiana sediment borrow areas, namely Sandy Point and Caminada pits. Vessel-based water sampling, tripod, geophysical, and 3-D numerical modeling methods are used to capture the temporal and spatial variations both inside and outside two dredge pits. Our results increase BOEM’s decision making ability (e.g., hypoxia frequency and duration, impact of dredge depth to hypoxia development, pit impact to surrounding water) regarding the development of a monitoring program and provide for better management of valuable sand resources.
