Abstract

An array of 15 moorings with 33 current meters was deployed in the deep water across the Continental Rise near 70°W for eight months. The data thus obtained provide the first synoptic view of the large amplitude, long period variability associated with the deep Gulf Stream region, shown here to have meridional scales of 150 km but zonal scales of less than 50 km. These fluctuations are associated with temperature variation of 0.5°C and exhibit a southward phase propagation of 10 cm/sec.
