[HTT23-P03] Environmental Monitoring Using Landsat-8 Data for Water Quality of Upper Mississippi River Basin and Hydrodynamic in the Louisiana Coastal Zone
The "dead zone" off the coast of Louisiana forms every year summer and is the second largest hypoxic zone in the world. Since 2000, as apart of the EPA sponsored Star Grant Research Program, several college based research organization in USA and Nihon University remote sensing research unit have contributed closely with the EPA Gulf Breeze Laboratory to develop a coupled hydrodynamic and biogeochemical model for the northern Gulf of Mexico hypoxia region. In this research, we are integrating satellite ocean color remote sensing imagery, hydrodynamic-water quality-sediment diagnosis modeling, and in situ measurements to assess and predict coastal ocean processes (such as nutrient-enhanced primary production) that regulate the development and size of hypoxic bottom waters in the region. The frequency, extent, and severity of coastal hypoxic events are increasing worldwide due to increasing eutrophication.
As a result, satellite-derived optical water mass classification procedures were well-combine with New Orleans land-use model and a model-derived stratification index to estimate the areal extent of coastal hypoxia in the northern Gulf of Mexico.
