Data included in this report were collected at Site A between December 1989 and December 2002 and at Site B from October 1997 to December 2002. The data include current, temperature, salinity, and beam attenuation at 3 depths (nominally 5 m below surface, 10 m above bottom and 1 m above bottom) and bottom pressure. The instrument turnarounds, typically in February, June, and September, resulted in gaps in the data series a few hours long. Instrument malfunctions, biological or mechanical fouling, deployment delays, and accidental disruption of the instrumentation caused longer gaps in the time-series data. In some instances, an entire 4-month deployment period lacks data. Plots of data coverage have been compiled for the entire project, or by year. For each parameter, the figures shows three lines corresponding to the nominal data sampling depths of 5 mbs, 10 mab, and 1 mab. The USGS mooring number is superimposed on the data line.
