The Mobile Bay National Estuary Program (MBNEP) contracted Barry A. Vittor and Associates, Inc. to conduct digital aerial image surveys of submerged aquatic vegetation (SAV) in and around Mobile Bay, Alabama in 2002. Two data sets were the result: digital vector data from imagery collected during summer 2002, and GPS field points data collected between July 2002 and April 2003 to groundtruth the imagery.

This projects primary goal was to provide data on occurrence and abundance of SAV resources within the fresh to saline coastal waters of the northern Gulf of Mexico, and to relate these findings to key environmental variables. The data set provides the collected data from 2013, 2014 and 2015 on site location, discrete water quality, aquatic vegetation cover and biomass by species. The same 384 sites were collected each year, between June and September.

Historic black and white aerial photographs of coastal Alabama (Mobile Bay and adjacent waters) from 1940, 1955, and 1966 were digitized and georeferenced using Blue Marble Geographic Transformer version 5.1. Outlines of distinguishable submerged aquatic vegetation (SAV) signatures in the aerial photography were digitized in a GIS environment, supplemented by visual examination of the photographic prints. ESRI polygon coverage of SAV beds was created in ArcView version 3.2.

These Submerged Aquatic Vegetation data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the rooted vascular plants such as seagrasses and freshwater/brackish species that grow in the intertidal and subtidal zones. It includes discrete samples, field observations, field photographs and related files originating from the Submerged Aquatic Vegetation Technical Working Group (TWG). The data were compiled by the NOAA Office of Response and Restoration (OR&R) and Trustees in the Data Integration, Visualization, Exploration, and Reporting (DIVER) data warehouse prior to being archived by the NOAA National Centers for Environmental Information (NCEI). The collection of files include environmental data used to determine the extent and magnitude of injury to the Gulf of Mexico ecosystem from the Deepwater Horizon oil spill. These data were used as part of the Programmatic Damage Assessment and Restoration Plan (PDARP) developed through the Natural Resource Damage Assessment (NRDA) conducted as a result of the April 20, 2010 explosion and subsequent sinking of the Deepwater Horizon offshore drilling rig in the Gulf of Mexico, about 40 miles (60 km) southeast off the Louisiana coast, that led to a major oil spill in the region.

This data set includes bi-monthly data on submerged aquatic vegetation species composition, percent cover, above and below ground biomass and environmental data at coastal sites across the fresh to saline gradient in Barataria Bay, LA.

Digitized maps of Mobile Bay and other coastal areas of Alabama, showing habitat types and species compositions of the vegetation in three broad categories of wetland: swamps, marshes, and submersed grassbeds. All areas in the Alabama Coastal Zone of less than 10 feet elevation above sea level, up to the fork of the Tombigbee and Alabama Rivers, were included in the inventory. Habitat boundary delineations were based on aerial photographs from 1979 and 1980, with transects by boat or foot for field verification in 1980-1982. Dataset includes habitat type classifications based on species compositions, and identifications of dominant species at each location.

Data and information collected by the submersible Johnson Sea-Link II at waypoints along its track during one dive of the 2002 "Islands in the Stream - Outer Shelf and Slope Habitats" expedition sponsored by the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration, August 5 - 15, 2002. Measurements and information include sub's position and depth; personnel assignments; dive, mission, target, and vehicle ID's; dive comments; hyperlinks to CTD plots; water temperature; and salinity. The Marine Operations Division of the Harbor Branch Oceanographic Institution provided the original submersible data. Quality assurance included a comparsion and synchronization of dive log waypoint depths and CTD depths, review of minimum and maximum values, and deletion of bad values.
