(This report describes monitoring programs for the Charlotte Harbor National Estuary Program study area.(including the Myakka River).The objectives of this report are to: 1) identify and describe all existing land, air, terrestrial and aquatic wildlife and vegetation, and water monitoring programs that pertain to the study area; 2) provide a summary of those programs both temporally and geographically; 3) help identify areas where monitoring is lacking or where protocols are inconsistent; and 4) assist existing programs in coordinating their efforts and increase understanding of programs across organizations.)

(The article evaluates different spatial interpolation methods for mapping submerged aquatic vegetation (SAV) in the Caloosahatchee Estuary, Florida. Coupled with a GPS system, the Submersed Aquatic Vegetation Early Warning System (SAVEWS) operates from a slow-moving boat and records bottom depth, seagrass height, and seagrass density.)

(The paper describes a method for rapid detection of submersed aquatic vegetation using a high-frequency, high-resolution digital echo sounder linked with GIS equipment. The technique provides good detection and measurement performance over a wide range of conditions for Vallisneria americana and seagrasses Thalassia testudinum, Halodule wrightii, and Syringodium filiforme.)
