During five of these flights sonobuoys were dropped in a linear pattern designed to show the temporal and spatial variability of the currents that constitute the gyre. A normal development consisted of approximately 15 sonobuoys dropped along the longitudinal line 4 deg 45 min W from the Spanish coast to within 30 km of the Moroccan coast. During the following 4 hours, the sonobuoys were relocated twice, their positions noted, and their individual drift speeds and directions derived. Aircraft precision radiation temperature and aircraft expendable baththermograph data were collected concurrently with the sonobuoy drops to determine the thermal structure of the water during the drift period. Inertial navigation winds (at the 300-m altitude of the aircraft) as well as other meteorological data, were aslo collected. Analysis of these data shows that at the time of these flights the cold approx. 17c waters along the outer portion of the Alboran Sea Gyre were the main constituent of the jet. These cold waters reached speeds of greater than 1.2m/s as compared to average speeds of 0.6m/s for the warmer water of the gyre. 收起
