Abstract
Application of Acoustic Basemaps and Real Time GIS in Shallow Water Track: Ocean, Coastal, and Marine Resources Author(s): Yvonne Allen, Charles Wilson, Harry Roberts Coastal Louisiana faces continual impacts from natural and anthropogenic processes that rapidly alter estuary configuration. Yet shallow depths and high turbidity often combine to limit what is known about the distribution and extent of habitats in the subsurface environment. LSU's Coastal Fisheries Institute has developed several innovative applications that use ArcPad with acoustic basemaps, realtime GPS display and acquisition, and other relevant geospatial data layers to advance research, industry, and management goals. This combination was used to guide field operations for ecological and geological research. We demonstrate the potential for using acoustic basemaps with realtime positioning and geospatial data to assist in spatially-based management of oyster harvest and production. Acoustic surveys can also be a valuable reference for coastal restoration and enhancement projects. We have conducted acoustic surveys to establish current conditions to guide future planning, as well as to mark a baseline against which future alterations may be measured.
