Relationship of marine birds to oceanic fronts off the northeastern United States. Technical progress report, April-November 1981
The role of fronts as determinants of pelagic distributions of zooplankton-feeding marine birds off the northeastern United States was investigated. Our analyses suggest that the shelf/slope and Cape Cod fronts are not convergent features, which accumulate biological or probably inorganic materials...
