520 3 |a Pelagic amphipods from the North American Slope Water, the Sargasso Sea, and from the core of two Gulf Stream cyclonic rings, Ring "D" and Ring "Bob" were identified. The samples were collected on two cruises which visited Ring D at six and nine months of age and two cruises which visited Ring Bob at one and five months of age. Correspondence analysis revealed the amphipod assemblage of a newly detached ring to be typical of the amphipod assemblage found in the Slope Water at the time of detachment. As a ring remained isolated from the parent Slope Water, the amphipod assemblage was found to be increasingly similar to the assemblage found in the Sargasso Sea and more dissimilar to the assemblage found in the Slope Water. The Slope Water assemblage was found to be variable in composition spatially and temporally. The Sargasso Sea assemblage was found to be stable in composition spatially and temporally. Physical and environmental parameters correlated with the changes in the amphipod assemblage in the core of a ring were temperature, salinity, standing stock of zooplankton, and standing stock of gelatinous zooplankton. Canonical correlation analysis delineated five groups of taxa. Taxa were grouped according to the correlation of their abundance with environmental parameters. Temperature, salinity and light were important physical parameters in delineating these five groups. The presence of salps and siphonophores were important biological parameters in the delineation of several of the groups. The relationship between these parameters and the distribution of the taxa are discussed.
