Today, IRS data is being used for a diverse range of applications such as crop acreage and production estimation of major crops, drought monitoring and assessment based on vegetation condition, flood risk zone mapping and flood damage assessment, hydro-geo-morphological maps for locating underground water resources, irrigation command area status monitoring, snowmelt run-off estimation, land use and land cover mapping, urban planning, biodiversity characterization, forest survey, wetland mapping, environmental impact analysis, mineral prospecting, coastal studies, integrated surveys for developing sustainable action plans and so on.

and Atchafalaya Rivers. The rivers usually flood in spring and sometimes into
summer, producing a stratified water column. The river-borne nutrients fuel
large phytoplankton blooms on the shelf. These physical and biological
processes can result in hypoxia on the shelf, and the "dead zone".
The Ocean Color Monitor (OCM), with 8 spectral bands similar to NASA's SeaWiFS
sensor, is used to estimate chlorophyll a concentrations as well as to quantify
suspended sediments. "True color" enhancements can provide additional
information on cloud cover, water mass color/types, vegetation health, and
bottom type. The fate of river waters and the location of ocean eddies can be
determined using various channels and channel combinations from "ocean color
sensors". One big advantage of the OCM sensor is that its pixels are 360m, in
contrast to SeaWiFS and MODIS which have 1 km pixels.
It is important to clarify that satellite-derived chlorophyll measurements can
be effected by CDOM, suspended sediments, and bottom reflectance. Thus, caution
should be taken when interpreting the patterns in coastal waters.C1214621397-SCIOPS1970-01-01T00:00:00.000Z/Oceansat Imagery from the Earth Scan LaboratoryLSU_ESL_OCEANSATNot providedSCIOPSLSU/ESLLSU/ESLCARTESIAN-90 -180 90 180falsefalsefalsefalsefalsefalsefalse0.65https://cmr.earthdata.nasa.gov/opensearch/collections.atom?uid=C1214621558-SCIOPSCMRechodev@echo.nasa.govReal Time Monitoring of Coastal and Estuarine ProcessThe Louisiana Coastal ocean receives the discharge from the Mississippi and
Atchafalaya Rivers through the "bird-foot" delta and through Atchafalaya Bay.
Over thousands of years, these river sediments have built the extensive
Louisiana wetlands, many of which are now in a state of decline. In support of
coastal research and management, we have developed satellite image products
that enable frequent surveillance of surface water temperatures, suspended
sediment concentrations, and pigments (chlorophyll a and CDOM ) along the coast
and in Louisiana's shallow lakes and bays where coastal restoration, via river
diversions, is underway. The MODIS "true color " images are particularly useful
for detecting river waters and studying sediment transport in Louisiana coastal
waters (see image above). In addition, selected clear sky NOAA AVHRR
temperature and atmospherically-corrected reflectance images (showing suspended
sediments) of the Mississippi and Atchafalaya Bay regions are available for
viewing extending back to 1999. Our highest resolution ocean color imagery is
acquired in real-time by the Oceansat-1 Ocean Color Monitor (OCM).The derived
chlorophyll 'a' product should be viewed as a gross estimate as it is usually
higher than true values due to the effect of CDOM and suspended sediments, both
of which occur in high concentrations along the Louisiana Coast.

measurements are providing daily updates on water quality and algal blooms in
Lake Pontchartrain and surrounding coastal areas in the aftermath of KATRINA.
We will be evaluating the bloom features through the collection and analysis of
water samples in key locations. HPLC measurements, spectro-radiometer data, and
phytoplankton identifications will assist in our assessments.
