The Sargasso Sea cruise surveyed marine birds and mammals in the Northeast Atlantic Ocean, during the summer of 2004. This survey onboard the Valiant 40 ocean-going research vessel Balaena, consisted of two survey legs: a sail from Halifax, Nova Scotia to Beaufort, NC (May 5 - 27), and a round-trip from Beaufort, NC to offshore waters north of the Bahamas (June 2 - 22). Seabirds were surveyed during the second leg of this cruise by Lesley Thorne, a graduate student from the Duke University Marine Laboratory.
The seabird survey data summarize the distribution and abundance of marine birds during the Sargasso Sea cruise.
SUPPLEMENTAL INFORMATION: This dataset includes survey effort and sightings during includes (on effort) and during focal follows of sperm whale schools (off effort). The survey track was recorded by logging a position every 10 minutes using the vessel's GPS.
