She went north instead ... I think. Two weeks ago, the manatee came visiting the UTMSI boat basin. She stayed almost all day .and I lectured her on· the hydrography of the south Texas coastal waters and bays. "It gets cold," I said. "One time, in December, I measured a temperature of -1.6 degrees under the bridge at Snoopys," I told her (being a Mexican Manatee . I thought, she would understand centigrade, and if I said 29 degrees she might think how cozy that was when, in fact, it was frigid). "Go south," I urged, and I went home when it got too dark to see her any more. The next day, she visited Deep Sea Headquarters and also the Aransas Pass, and then she was gone. "She's gone south," I thought, as the days ::..:. went by and no word of her walrus-like visage came. Then, despite my telling her not to go anywhere near places like the ditch alongside an oil refinery, there came a report of a manatee in Buffalo Bayou. That's the Buffalo Bayou in Houston, a place not known for the quality of its waters which can get just as cold as ours do here. Now, I do not know for sure whether the Houston manatee is "our" manatee, but certainly two weeks is enough time for her to travel that far. 97 30' 9715' 9700' 9645' MANATEE SIGHTINGS; Oct - Nov 1995 I learned a little more about the history of manatees in Texas, thanks to Dr. Wes Tunnel who sent me a copy of an article appearing in the August 1944 issue of Texas Game and Fish magazine, the forerunner to Texas Parks and Wildlife. The article was written by none other than Gordon Gunter, Marine Biologist (as the masthead describes him). 1944 was two years before full time activities really began for UTMSI. Dr. Gunter eventually became Director of UTMSI and we hope will help us in celebrating our 50th Anniversary next year. He said that "there have been reports of Texas fishermen being scared partly out of their wits by a huge black animal that rose and snorted.beside their boats." In 1851, Mexican naturalist Dr. Luis Berlandiere sent a manatee found in the Lower Laguna Madre to the U.S. National Museum. Manatees were seen almost every summer in the Rio Grande and Lower L~guna. One taken alive near Port Isabel was exhibited in various parts of the U.S. Since 1913, Dr. Gunter reported, manatees have not been seen in Texas, although dead ones were found in Capano Bay in 1928, and in Cow Bayou near Sabine Lake in 1937. He described a manatee rib bone he had on his desk at the time. As manatees have the "heaviest 2 type of bone in the animal kingdom," his rib "is as solid as a piece of ivory." It had no hollow for the bone marrow. Since that time, manatees have been reported in 1979 (Corpus Christi), 1986 (Bolivar Peninsula - carcass found and skeleton now in the TAMU College Station collection), 1992 (Lower Laguna), 1993 (Matagorda Peninsula - dead), 1994 (twice in Laguna Madre), September 1995 (cow and calf in Galveston Bay), and then the present sightings, almost certainly the same animal, in Mansfield Channel, the Land Cut, Barney Davis Power Plant [1], the· Naval Air Station [2], Naval Station Ingleside [3], Rockport Harbor [4], Koch Refinery East La Quinta Channel [5], Texas State Aquarium [6]; Ship Channel [7],UTMSI Boat Basin [8], Deep-Sea Headquarters [9], and now ...

The ERF Governing Board presented the award to Drs. Paul Montagna, Ken Dunton, and Terry Whitledge in Corpus Christi last week. The ERF represents about 2,800 scientists that conduct research in coastal watersheds, rivers, bays and shore environments. "The international conference was supported by many Coastal Bend companies including: BP Exploration, Central Power and Light, H .E.B., Hoechst Celanese, Hydrolab Corporation, Lower Laguna Madre Foundation, Oxy Chem-Ingleside, Port of Corpus Christi, Reynolds Metals-Sherwin Alumina Plant, Russell Veteto Engineering, Texas Shrimp Association, Union Carbide-Port Lavaca, and Valero Refinery. The meeting attracted over 700 marine scientists and resource managers from the United States, Europe, South America, Asia and Australia," said Dr. Paul Montagna, Conference Chairperson. "Over 115 graduate students and 12 minority undergraduate students made presentations at the meeting," according to Terry Whitledge, who organized the undergraduate research program. "One of the most popular topics at the conference was how additions of inorganic nitrogen from sewage, 4 fertilizer, or animal wastes by river or groundwater leads to changes in water quality in coastal systems," said Ken Dunton, Program Co-Chair. "Scientists from around the country have noted significant increases in both the frequency and duration of harmful algal blooms and losses of seagrasses."

To understand current patterns and predict future trends, we establish a geologic record of coastal change along the Gulf of Mexico coast. A study examining the natural versus anthropogenic mechanisms of erosion reveals several sand sources and sinks along the upper Texas coast.

  • Galveston Bay the Effects of Freshwater Inflow on Water Temperature
    Galveston Bay The Effects of Freshwater Inflow on Water Temperature David Christiansen Introduction In January of 2012, the Hodges group became involved in a project funded by the Gulf of Mexico Research Initiative (GoMRI). This project will include taking field measurements in several bays along the U.S. coast of the Gulf of Mexico. These measurements will include water velocity, conductivity, temperature, etc. with the end goal of understanding the flow in the bays and creating a model capable of predicting the flow as well as how an oil spill would propagate in the bays. The first bay of interest is Galveston Bay near Houston, TX. This bay was given first priority because of its higher “political” implications (people are worried about another Hurricane Ike) when compared to the other bays to be studied (Corpus Christi Bay, TX and Barataria Bay, LA). Although the group’s particular role in the project does not include any of the modeling of the bay, it would be beneficial to understand the inflows into Galveston Bay and how they affect the flow in the entire bay. Galveston Bay is located in southeastern Texas, about 20 miles southeast of Houston. The bay has two main freshwater inflows: the San Jacinto River flowing in from the northwest and the Trinity River flowing from the north. The Trinity River is the main freshwater source in the system, with a mean daily discharge of 6620 cubic feet per second (cfs) (USGS). The San Jacinto is much smaller, having a mean daily discharge of 372 cfs (USGS). A map of the area can be seen below in Figure 1.

  • Inter-Model Comparison for Corpus Christi Bay Testbed
    TWDB 0904830892 Final Report for Project Technical support – Inter-model comparison for Corpus Christi Bay testbed May 2010 Principal Investigators Y. Joseph Zhang, Ph.D Phone: 503-7481960 E-mail: [email protected] NSF Center for Coastal Margin Observation & Prediction, OGI School of Science & Engineering, Oregon Health & Science University (OHSU), 20000 NW Walker Road, OR 97006 Summary We report results for Corpus Christi Bay circulation using OHSU‟s SELFE model (Zhang and Baptista 2008), as a part of the inter-model comparison exercise for this system. The time period chosen is two wet years (2000 and 2001), although we will focus on year 2000 as the data for 2001 is being withheld from modelers for “blind” comparison. Previously we have conducted model-data comparison for two dry years (1987 and 1988), and demonstrated that the model was able to capture the overall variation of salinity and temperature. However, comparisons were lacking for other hydrodynamic variables such as elevation and velocity, partly due to issues related to the observational data. Here we conduct a comprehensive model skill assessment using long-term data for elevation, salinity and temperature, as well as short time series of velocity data collected by TWDB scientists during the May 2000 survey. We show that the model is able to capture long-term trend of salinity and temperature, and is also accurate for elevation (both tidal and non-tidal components) and velocity. 1. Overall goal The main goal of the exercise is to study the long-term elevation, salinity and temperature trend in the Corpus Christi Bay system.
