    Humpback Whale Research: Breeding Grounds

     
         
     

    The Provincetown Center for Coastal Studies performs collaborative research at three oceanic breeding grounds: the West Indies (North Atlantic), the Hawai'ian Islands (North Pacific) and American Samoa (South Pacific). For detailed information on our research findings, check our scientific publications. For more general information about humpback whales, look here.

    West Indies

    PCCS began studying humpback whales on their North Atlantic wintering grounds in the late 1970s. Study areas have included several areas off the Dominican Republic (Silver and Navidad Banks, as well as Samana Bay), Puerto Rico, Virgin Bank and the northern Leeward Islands. Our work in these areas has focussed primarily on the composition of the wintering population, distribution and habitat use, migration and aspects of the mating system.  Photo-identification data have played a particularly important role in determining the feeding ground origin of individuals, as well as the movements of individuals among breeding areas.

    A few publications that have resulted from this research are as follows:

    Our largest West Indies field effort was part of the international Years of the North Atlantic Humpback Whale project (YoNAH) in 1992 and 1993. The details of that study and its results are described here.

    American Samoa

    American Samoa is a South Pacific humpback whale breeding area in Oceania.  Humpback whale stocks in Oceania were depleted by commercial whaling and their recovery status remains uncertain. PCCS has performed collaborative research at the main island of Tutuila annually since 2003. The goal of this work is to define the local population, to clarify its relationship to other parts of Oceania and to identify its Antarctic migratory destinations. Additionally, our work has contributed to the understanding of local dolphin populations.

    This research is done in partnership with the Hawaiian Islands Humpback Whale National Marine Sanctuary. Other collaborators and supporters include the American Samoa Department of Marine and Wildlife Resources, the Fagatele Bay National Marine Sanctuary, the US National Park Service, the US National Marine Fisheries Service, the Government of Samoa, the Antarctic Humpback Whale Catalog and the South Pacific Whale Research Consortium.
