Abstract

In March 1976, the Bureau of Economic Geology began an extensive program to sample the submerged lands of Texas. Using precise radionavigation techniques, benthic samples were taken on a 1-mile interval from rivers to 10.36 statute miles (3 leagues) offshore. By January 1978, 6,697 samples had been collected.

Sample analysis included:

textural studies geochemical (trace element, organic carbon, uranium equivalent) determinations bathymetry geophysical data biological studies This report on the biology of the Galveston-Houston area will provide preliminary information on benthic macroinvertebrate distribution and diversity. Further analyses would provide a more extensive biological data base to help assess and predict the problems and potential impact of development on State submerged lands.
