Coastal Change Analysis Program (CCAP)

The Coastal Change Analysis Program (C-CAP) uses satellite imagery and aerial photography to monitor areal extent, functional status, and change in these critical habitats. The C-CAP produces a nationally standardized database of land cover and land-change information for the coastal regions of the U.S. C-CAP products provide inventories of coastal intertidal areas, wetlands, and adjacent uplands, with the goal of monitoring these habitats by updating the land-cover maps every 5 years. C-CAP products are developed using multiple dates of remotely sensed imagery and consist of raster-based, land-cover maps for each date of analysis, as well as a file that highlights changes that occurred between these dates and where the changes were located. This map presents the C-CAP land cover analysis of Landsat imagery taken in 1996, 2001, 2006, and 2010 for coastal areas of Texas, Louisiana, Mississippi, Alabama, and Florida.

CMECS Water Column Productivity Modifier

Seasonal five year mean, as estimated from satellite imagery, of chlorophyll in northern Gulf of Mexico. Processed MODIS-Aqua satellite imagery from January 2005 - December 2009 were used to derive chlorophyll concentrations using the OC3 algorithm. In situ data from the Southeast Area Monitoring and Assessment Program (SEAMAP) program were overlaid on the modeled data. Both the satellite data and the SEAMAP data were then reclassified into Coastal and Marine Ecological Classification Standard (CMECS) Water Column component categories. The CMECS is a catalog of terms that provides a means for classifying ecological units using a simple, standard format and common terminology. CMECS offers a way to organize and interpret data about the marine environment, and it provides a common platform for inter-relating data. Measurements are in ug/l. Seasons are as follows: Fall (September - November), Winter (December - February), Spring (March - May), Summer (June - August).

Four-Class Marsh Vegetation Type

Coastal zone managers and researchers often require detailed information regarding emergent marsh vegetation types for modeling habitat capacities and needs of marsh-reliant wildlife. The U.S. Geological Survey, in collaboration with the Gulf Coast Joint Venture, the University of Louisiana-Lafayette, Ducks Unlimited, Inc., and Texas A&M; University - Kingsville, has produced a classification of four types of marsh vegetation for Texas, Louisiana, Mississippi, and Alabama.
