LATEX Shelf Data Report
"This report describes the data availability of the SeaData 635-8 wave gauge deployed by the Texas-Louisiana Shelf Circulation and Transport Processes Study of the Louisiana-Texas Shelf Physical Oceanography Program (LATEX). LATEX was funded by the U.S. Minerals Management Service under OCS contract No. 14-35-0001-30509 (Jochens and Nowlin, 1994). This report follows the same format as the LATEX-A Data Report: MiniSpec Directional Wave Gauges (DiMarco et al. 1995a). The two volume MiniSpec Data Report discusses MiniSpec data collected from the beginning of the LATEX field study in April 1992 through December 1994. Kelly et al. (1993) document the calibration and performance of the MiniSpecs during their first year of deployment. This report focuses on the data recorded by the SeaData 635-8 wave gauge. The SeaData wave gauge was deployed six times during the LATEX field program at 3 different locations and recorded bottom pressure only. The observed SeaData pressure records are suitable for estimating wave statistics. One difference between the LATEX Mini- Specs and SeaData data is that the MiniSpecs also recorded current information to provide estimates of the directional wave spectrum. Because the SeaData recorded only bottom pressure, only the non-directional wave spectrum could be estimated. The SeaData instrument also only operated in burst mode and, therefore, did not yield half-hourly seasurface height estimates. Sea surface height may be estimated, however, by averaging the SeaData pressure time series. The availability of sea surface height estimated by the Sea- Data is addressed in the LATEX-A Data Report: Current Meters (DiMarco et al. 1997). In addition to data availability, this report also documents the calculation of wave statistics, such as significant wave height and peak spectral period, which were not provided in the original National Oceanographic Data Center (NODC) distributions submitted to the NODC by the LATEX program. Three data sets per instrument deployment exist for the SeaData wave gauge: the original raw pressure time series, time series of basic wave statistics, and time series of sea surface height. It is clear, however, that the general analyses presented in this report can provide important information and serve as pointers for future, more specific, analyses"--Introduction.
