Project Description

The Deepwater Horizon (DWH) oil spill exposed the nationis largest and most productive wetland-estuary, the Mississippi River Delta coastal wetland ecosystem, to an unprecedented level of oil contamination and potential damage. The coastal marshes support a host of environmental and economic services that depend on a healthy, well-functioning plant-soil-microbial complex to drive the food web base. For 7 years, the PIis team has monitored the effects of the DWH oil spill in Louisiana salt marshes through 16 field-based data collections that quantify the impacts and recovery of a broad array of flora, fauna and microbes. Continuation of this research in heavily-oiled shorelines where marsh plants that serve as foundation species suffered severe mortality is critical to assessment of coastal marsh recovery, which to-date is incomplete, and to a better understanding of marsh resiliency to oil contamination. This proposal will (1) document and catalogue the decade-long impact of DWH oil on the coastal marsh plant-soil-microbial complex; (2) quantify rates and controls of long-term recovery; (3) catalogue oil transformation compounds detected in oiled salt marsh sediments up to 10 years after the spill and determine their toxicity; and (4) identify potential correlation between vegetation, microbes and transformed oil compounds in oiled salt marshes.
