Abstract
Near-bottom current speeds were measured at distances of from 1–3 m above the ocean floor west of Oregon. The instrument used was a temperature-current probe designed to measure temperatures at 8 levels and current speeds at either 1 or 2 levels near the sea floor. Sampling was carried out at 6 positions. A distribution of recorded current speed versus water depth (from 725 to 2900 m) reveals a systematic and significant increase in current speed with decreasing depth. Mean current speeds for depths from 2700 to 2900 m were approximately 2 cm/sec with maxima of up to 6 cm/sec. Mean current speeds for continental slope stations, with depths from 725 to 1700 m, range from 5 to 20 cm/sec with maxima of 20–40 cm/sec depending on water depth.
