Topic: Buried or fried? Understanding sedimentation and temperature effects on native species restoration in the South Slough National Estuarine Research Reserve and the Coos estuary

Designated one of Oregon’s three “deep draft development” estuaries, the Coos estuary has many diverse users who share a need for better information about water and sediment flows under current and future conditions. In particular, we are focused on how estuarine circulation influences eelgrass health and native oyster restoration projects. Working closely with the South Slough NERR and the Partnership for Coastal Watersheds, a local stakeholder group, to accomplish these management objectives, we are collecting new sediment core data to characterize sedimentation over various time and space scales. In addition, we are adding water temperature as a variable to existing, validated hydrodynamic simulations to explore temperature patterns across the estuary. Finally, we put these new data in context with previous work that investigated the estuarine response under very different historic bathymetric conditions and compare them to present day and a future proposed deepening and widening of the estuary channel.
