The Matagorda Bay Health Evaluation (MBHE) component of the LCRA/SAWS Water Project (LSWP) Study Plan was created to assess the environmental effects that could result from further changes to inflow patterns in the Matagorda Bay system. Benthic analysis is one of several measures outlined in the MBHE framework to determine bay health. This study examined how benthic macrofaunal community structure has varied over space and time in response to changes in inflow in both the Lavaca and Matagorda Bay systems. In general, the Matagorda stations E, F and D exhibit healthier ecosystem function than the Lavaca Bay stations. The investigation also found direct relationships between inflow and salinity on benthic communities. While there were few significant relationships found between univariate macrofaunal community measures and salinity or wet/dry periods, there were nevertheless distinct station differences in community structure along salinity gradients. Also, there were three indicator species of freshwater inflow effects. The polychaete Streblospio benedicti declined continuously from freshwater stations to marine stations D. The bivalves Macoma mitchelli and Mulinia lateralis exhibited strong declines along the salinity gradient from freshwater to marine. This implies that reduced flows will cause the upstream communities to take on characteristics of downstream communities. Over the next year, more analyses will be performed to assess if trophic levels are as important as species-level data, and if rare species play a significant role in ecosystem function. Neither of these factors were analyzed in the current preliminary report. Thus, further analysis of existing data, as well as possibly more field studies, is needed to more thoroughly assess the relationship between inflow and community structure in the Lavaca-Colorado estuaryItem Item Length-length and weight-length relationships of seven deep-water fishes in the Gulf of Mexico(1988) Matlock, Gary C.; Nelson, Walter R.; Jones, R. S.; Green, A. W.Regression coefficients for equations of the form Y = a + bX were estimated for total length (TL) and whole weight (W) as a function of standard length (SL) and fork length (FL) and vice versa for seven deep-water fishes. All lengths were measured in millimeters and all weights in grams. There was a significant correlation between weight and length and the types of length measurements for all species. However, the amount of variation explained by each regression varied among species. Weight-length regressions were less precise than length-length regression, as they generally are, because weights of small fish measured at sea are more inaccurate than those of large fish.Item Survey and findings of beach debris on Mustang Island, Texas(1988) Amos, Anthony F.Item Quantitation and organic geochemical characterization of petroleum-like materials found on an undisturbed beach of the Padre Island National Seashore(1980) Scalan, Richard S.; Winters, J.

The CAMP project was a multidisciplinary study to detect and evaluate the long-term biological impacts of continental shelf oil drilling and production. The study was centered around a proposed platform site named Julius, which was never put into service. Samples were collected in the Santa Maria Basin on a regional scale (10- 20 km). Harpacticoids are the second most abundant meiofaunal taxa in the Santa Maria Basin. Harpacticoids have been intensively studied in the Atlantic OCS. However, Pacific studies are limited to collections made in shallow water. There are a great number of undescribed species in the CAMP samples taken from the Santa Maria Basin. The present study is rather limited in scope and only touches on some of the dominate species found. It contains full taxonomic descriptions of six species, a pictorial key of 18 dominant species, and drawings of 42 other unknown species.Item Nitrogen cycling in East Matagorda Bay(2002) McCarthy, Mark J.
