Geologist Julie Bernier presents findings from the Gulf Coast Subsidence Project at the Louisiana Coastal Neotectonics Workshop

Release Date:

SPCMSC geologist Julie Bernier was invited to present findings from the Gulf Coast Subsidence Project at the Louisiana Coastal Neotectonics workshop, June 3–5, 2020, organized by The Water Institute of the Gulf.

The Water Institute of the Gulf has assembled an expert panel composed of recognized experts in the fields of neotectonics/subsidence and geomorphic/sedimentary response in the Louisiana coastal region. The panel is charged with weighing the data, interpretations, and conclusions presented to them by scientists conducting research related to this topic during the workshop in the context of fostering open discussion of neotectonics and coastal restoration at the planning time scale. Through a series of workshops, the panel provides a forum for scientists to present their research on neotectonics and its potential impacts on management of coastal natural resources. This is the third of three planned workshops. Julie will be presenting results from the Gulf Coast Subsidence Project, ​which investigated the physical processes and human activities that contributed to historical wetland loss in coastal Louisiana and the spatial and temporal trends of that loss.

Regional map showing historical (1932-2004) wetland losses and geologic setting of the Mississippi River delta plain, Louisiana. The delta plain was constructed by sediment transported through distributary channels that began prograding about 7,000 years ago and deposited sediment in overlapping delta lobes. Thick aggradational peats that accumulated in interdistributary areas underlie much of the emergent delta-plain wetlands. White box encompasses study sites where coring and bathymetric surveys were conducted as part of the Gulf Coast Subsidence Project.

Gulf Coast Wetland Shoreline Change

Land and seafloor slopes are generally low along the coasts in the Mid-Atlantic and Gulf Coast states, making wetlands and estuaries vulnerable to sea level change, subsidence, and extreme events (e.g., hurricanes and tropical storms). Land-use change and land loss have been mapped extensively and with increasing frequency, but the link between land loss and the processes responsible for...
