Freely Drifting Swallow Float Array: August 1990 NATIVE 1 Experiment (First Deployment)

Representative data collected by the Marine Physical Laboratory's set of Swallow floats during event 1 of the NATIVE 1 experiment are presented. The deployment location was in the northwest Atlantic Ocean around 31 deg 15.6' N, 74 deg 53.2' W, almost 600 km east of Savannah, Ga. Nine...

Description
Summary:Representative data collected by the Marine Physical Laboratory's set of Swallow floats during event 1 of the NATIVE 1 experiment are presented. The deployment location was in the northwest Atlantic Ocean around 31 deg 15.6' N, 74 deg 53.2' W, almost 600 km east of Savannah, Ga. Nine midwater Swallow floats were deployed; two equilibrated at a depth of about 400 m and the remaining seven were staggered about every 100 m starting at 1100 m down to 1700 m. They were put into the water at about the geometric center of a triangle, whose sides were approximately 6.5 km in length, formed by the three remaining floats which were tethered to the 3180m-deep ocean bottom by 3.05-m lines. This report presents the Swallow float deployment positions both in plan view and in depth, the other acoustic sensors in the experiment, the known signal sources during the experiment, a summary of the Swallow float log, and representative Swallow float data.
