| Summary: | This report documents water column measurements made during the 1994 Loch Linnhe experiment, a joint US/UK radar ocean imaging experiment. Part 1 summarizes the profiles of temperature, salinity, density, Brunt-Vaisala frequency, and horizontal currents resolved into along and cross track directions. Internal wave dispersion relations, phase and group velocities, and eigenfunctions for modes 1 and 2 are computed for each profile. The effect of depth on these derived internal wave parameters is examined as well by computing eigenvalues and eigenfunctions for two different depths. The trials were conducted in Loch Linnhe, Scotland during the period from September 4, 1994 to September 17, 1994. The measurements reported herein were made from on board the R. V. Calanus, a research vessel operated by the Dunstaffnage Marine Laboratory (DML). The Calanus was moored approximately 125 meters from the track of the wake generating ship, either the R. V. Colonel Templer or a {open_quotes}Dog{close_quotes} class tug, the Collie. The depth at the mooring location was approximately 45 meters, while the depth at the closest point along the ship track was approximately 80 meters.
