Description: The oysters data set is a compilation of three data sets. The first data set was developed by Dr. Eric Powell of Texas A&M University's Department of Oceanography under the auspices of the Galveston Bay National Estuary Program. The reefs were mapped using acoustic equipment designed to return echo signal from the bay bottom. In very shallow areas where a smaller boat was used, it was not possible to hang the equipment over the side of the boat; therefore a poling technique was used to determine the location of the oyster reefs. The second and third data sets were both acquired from the Texas Parks and Wildlife Department. One was developed by a team led by Warren Pulich and used aerials circa 1989. The other was developed by Betsi Blair which also used aerial photographs and surveyed submerged aquatic vegetation including oyster reefs. <a href='xml/TX_TNC_ERA_Oysters.xml' target='_blank'><b>Metadata</b><a></br>
