SUMMER SEABIRD DISTRIBUTIONS IN DRAKE PASSAGE, THE CHILEAN FJORDS AND OFF SOUTHERN SOUTH AMERICA
Summary The paper summarizes observations on the pelagic distributions of sea‐birds in Drake Passage and off southern South America, collected by ship‐borne observers between December 1969 and April 1970, and in March and April 1972. The birds' distributions have been related to sea surface tem...
