Nearshore currents and water temperatures were measured almost continuously from June 23 through December 22, at five moorings in an array centered 4 km offshore of south Chicago. The mooring array was square, each side 1.6 km long. A current-meter mooring was placed at each corner, with one mooring in the center. One Bendix Q-15 current meter and one YSI temperature sensor were fixed to each mooring line. Each meter and associated temperature sensor was placed at middepth; the water depth averaged about 12 m. The following types of graphs are presented for current and wind observations: (1) U, V flow components versus time, (2) specific kinetic energy versus time, (3) flow speeds and directions versus time, (4) composite velocity histograms and associated U, V-component histograms, and (5) progressive-vector diagrams. Also presented are listings of the component programs used to reduce the data. Currents in the region were dominantly shore-parallel. Water temperatures reflected several episodes of upwelling and downwelling. Detailed analyses of the data will be presented in subsequent reports.
