San Luis Pass

Cover: The cover photo is a Landsat Thematic Mapper image of San Luis Pass, Texas. San Luis Pass is located about 45 km southwest of Galveston, Texas, on the Gulf of Mexico. The image is about 20 Km across with San Luis Pass in the lower right, Galveston Island to the northeast, and Follets Island to the southwest. This false color composite image assigns PC (Principal Component) band 1 to red, PC band 2 to green, and PC band 3 to blue. The red areas represent vegetation on the mainland and on the barrier islands. The green areas are shallow water and shoals in the bays and lagoons behind the barrier islands. The blue water of the Gulf of Mexico is bordered by pale green breaking waves in the surf zone and a plume of brackish water at the mouth of San Luis Pass.

The image was generated by Rebecca Thomas `96 and Maryellen Sault of SUNY College, Buffalo, during a Keck Geology Consortium summer research project held at Trinity University in San Antonio, Texas. The results of the research, "Shoreline Changes of San Luis Pass, Texas, from 1930 to 1990," were presented at the Eighth Keck Research Symposium in Geology at Pomona College, Claremont, California, April 1995. The Keck research project entitled "Geologic Remote Sensing and Multispectral Image Processing" was directed by Glenn C. Kroeger, Trinity University, San Antonio, Texas, with William T. Fox, Williams College, and Richard C. Stenstrom, Beloit College, as faculty members on the project. William Fox also served as Rebecca Thomas's faculty advisor for the project after her return to Williams. The project was jointly sponsored by grants from the W. M. Keck Foundation and the National Science Foundation.
