Movements of satellite-monitored humpback whales on their feeding ground along the Antarctic Peninsula

摘要: Humpback whales were instrumented with sat- ellite transmitters oV the western Antarctic Peninsula in January of 2004-2006 to examine their movement patterns and habitat use. Whales tracked from 4 80 days (mean = 36.5 days). Distance travel rate estimates for nine individuals ranged 223 4,356 km 17 75 km/day, respectively. Considerable individual varia- tion was observed direction, speed range move- ments. The overall pattern characterized by short- long-distance movements between presumed foraging areas relatively short residency times. Travel rates lower at these sites, erratic movements, than during traveling them.
