Coastal Louisiana: Impacts of Hurricanes on Salt Marsh and Mangrove Wetlands
This video describes research conducted by Dr. Karen McKee, USGS Research Ecologist,
and her university partners, Dr. Irv Mendelssohn (Louisiana State University) and
Dr. Mark Hester (University of Louisiana at Lafayette). They are studying the effects
of hurricanes on marsh and mangrove wetlands in the Mississippi River Delta, which
contains over 40% of the U.S. wetlands in the lower 48 states. Although hurricanes
can have devastating effects on human communities, they may provide nourishing sediment
to subsiding wetlands. This video describes an investigation to determine how much
storm sediment from Hurricane Gustav (2008) was deposited in marsh and mangrove
stands and if these different types of vegetation influence sediment capture. McKee
and colleagues carried out their research by helicopter, which is the only way to
sample the vast wetlands in coastal Louisiana. The results of their investigation
will lead to a better understanding of how hurricanes may benefit coastal wetlands.

Effects of Sea-Level Rise on Coastal Wetlands in the Mississippi Delta
This video describes research being conducted by Dr. Karen McKee, USGS Research
Ecologist, and her university partner, Dr. Julia Cherry. Their goal is to better
understand the effects of sea-level rise and other global change factors on coastal
wetlands in the Mississippi River Delta. This region contains over 40% of the U.S.
wetlands in the lower 48 states These wetlands support commercial fisheries, provide
habitat for waterfowl and wildlife, and act as storm buffers, protecting several
important ports and cities such as New Orleans McKee and Cherry are conducting field
and greenhouse experiments to quantify how plant productivity contributes organic
matter to vertical soil building, which helps to counterbalance sea-level rise.
They are also investigating how elevated concentrations of carbon dioxide in the
atmosphere may stimulate plant production and help marshes build vertically and
avoid submergence. Their research is contributing to a better understanding of how
coastal wetlands persist in the face of changing sea levels and how they may respond
in the future.
