Abstract
Water level data from Corpus Christi Bay, Texas, collected during a 53-day period in early 1972 are used to obtain a time series of computed Bay volumes. Spectral analysis indicates exchanges occurring primarily at tidal periods, and over time intervals longer than about 50 h. Atmospheric pressure data from three locations in South Texas are used to compute regional pressure gradients. Coherence-squared spectra computed from time series of Bay volumes and surface pressure gradient components suggest that meteorologically forced exchanges between the Gulf of Mexico and Corpus Christi Bay are primarily due to Ekman transport across the continental shelf, maintained by quasi-steady winds paralleling the coast, and onshore-offshore winds at periods of 60–100 h.
