Abstract : During the fall of 1994, the Shallow Water Active Classification-1 (SWAC-1) test was conducted in the Malta Channel. The three surface platforms involved in the test were utilized to collect environmental data; SWATH bathymetry, bottom sediment samples, currents, XBT temperature profiles, and CTD profiles. Shipboard weather observations were recorded as well as meteorological data measured by a moored Wind Speed, Direction (WSD) buoy. Oceanographic variability over the Malta Bank is evident in the profiles presented. A mixed-layer is present from the surface to 30-40 m with oscillations in both the thermocline and in the deeper water column. These deeper oscillations produce a sound channel near 70 m in many of the profiles. Sound speeds were computed using Wilson's (1960) equation. The instruments and data collected are described with data listed in four appendices.
