摘要：

The semi-enclosed nature of Long Island Sound makes it ideal for surface and sea-bed drifter studies. A U.S. Coast Guard H-3 helicopter provided a "synoptic" launch within a half tidal cycle. Drifter releases were conducted on 18 June 1973 at a total of 50 stations in Long Island and Block Island Sounds. Drops were made at various altitudes and speeds in order to determine optimum release conditions. As of 18 August 1973 at least one drifter has been returned from 28 of the 50 stations (56%). Surface drifters (one to a station) have been returned from 18 of 50 stations (36%). Total return of 52 of 250 bottom drifters (20.8%) has been logged. The helicopter seems eminently suitable for near-shore launching of drifters where its limited range is not a problem and synoptic deployment is desirable.
