Description: This data represents natural historic oyster reefs along the Texas coast and bays in 1975. The reefs were digitized from a NOAA technical report called Cooperative Gulf of Mexico Estuarine Inventory and Study - Texas: Area Description by Ricahard A. Diener.Complete reference: http://galveston.ssp.nmfs.gov/publications/pdf/189.pdf

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.

Description: In 2006 and 2007 the NOAA Coastal Services Center purchased services to process existing and new digital multi-spectral imagery and create digital benthic habitat data from this imagery for selected Texas coastal bend bays. The Center worked cooperatively with Fugro-Earthdata, the Texas Parks and Wildlife Department (TPWD) and the Texas A University Center for Coastal Studies to develop benthic habitat data, primarily Submerged Aquatic Vegetation (SAV) for several coastal bays. This data will support the state's recently adopted Seagrass Monitoring Program which calls for regional mapping of SAV for status and trends assessment. The Center, Texas A, and TPWD have coordinated on the requirements of this project. Source: NOAA Coastal Services Center http://www.csc.noaa.gov/texasatlas/

Description: The Coastal Island Bird Rookery shapefile dipicts bird rookery locations on the coastal islands of Texas. The file is in progress. Over 130 features were added to an origional file of unknown origin containing 154 features. The update represented in this files includes the additional features, which were digitized based on 2008 naip imagery and ESRIs “ESRI_Imagery_World_2D” online layer.

Description: To address the issues of concern, and in response to the requirements of the Coastal Coordination Act, the Coastal Coordination Council has designated Oyster Reefs as a coastal natural resource area requiring special management under the Coastal Management Program and defined as Natural or artificial formations in intertidal or subtidal areas that are composed of oyster shell, live oysters, and other organisms and that are discrete contiguous, and clearly distinguishable from scatter- ed oysters. Oyster reefs not only support the oyster fishery but also serve as habitat, forage ground, or hiding places for numerous estuarine species.

Description: Bathymetry was constructed from xyz hydrographic survey data from the northwest Gulf of Mexico Continental Shelf and inshore areas. The underlying source data are about 3.5 million soundings from 300 historic hydrographic surveys conducted in 1930-2005 by the U. S. Coast Survey, and available from the NOAA National Geophysical Data Center. Vector contours were derived from the source data sets using the GMT (Generic Mapping Tools) software package. Editing of source data reconciled: differences in zero datum; land subsidence with time; a diversity of survey methods and depth units; various other errors/ inaccuracies; and changes in nearshore bathymetry with time. The data were gridded, surfaced, smoothed, and re-gridded prior to contouring. Editing of contours was carried out in the Adobe Illustrator software package. The vector contours were imported from Adobe Illustrator into Arc-GIS, where GIS-compatible files containing the contours were created. As a final step, the contours were subjected to line smoothing.

Description: Salinity maps of estuarine habitat have been developed for all estuaries in the Gulf of Mexico. Each map consists of five depth-averaged salinity zones (0-0.5, 0.5-5, 5-15, 15-25, >25 parts per thousand) for four salinity (hydrographic) seasons (low, increasing, high, and decreasing). In addition, a regional portrayal of salinity has been organized by calendar seasons for all these estuaries. This enables a user to look at a consistent seasonal time period across multiple estuaries to compare and contrast salinity habitat.

Description: The Texas Coast portion of the Gulf of Mexico includes nine major bay systems. The entire region is part of the Western Gulf Coastal Plain ecoregion. The coastal plain is characterized by a gently sloping, lowland environment. Historical periods of coastal flooding and intense sediment deposition have sculpted the Gulf of Mexico shoreline. Today, much of the coastal region is comprised of large bays, lagoons, extensive wetlands, sandy beaches, and barrier islands. The estuaries are typically bordered by tidal marshes and mud-sand flats. Most of the Texas estuaries are shallow, have turbid water due to suspended sediment, and are semi-enclosed by barrier islands. This file shows the boundaries of the Texas bays.

Description: All shellfish in Texas waters must be harvested from approved or conditionally approved areas. The status of shellfish growing waters in Texas estuaries is subject to change by the Texas Department of State Health Services at any time. These changes may be due to high rainfall and runoff, flooding, hurricanes and other extreme weather conditions, major spills, red tides, or the failure or inefficient operation of wastewater treatment facilities. The current status of shellfish harvesting areas may be obtained from the local Texas Parks and Wildlife office. This layer dipicts classification of shellfish harvesting areas.
