The NMFS was advised of the situation and, on 10 August 1979, NPS and NMFS representatives met in Seattle, Washington to review available information concerning the nature and possible causes of the departure of whales from the Bay. Another meeting was held in late August to discuss the problem with members of the cruise ship industry. It was agreed that additional research was needed to better define the nature and possible causes of the problem and that a meeting should be held to discuss possible research approaches with other professionals in the marine mammal field. These decisions led to the meeting described in this report.
Subsequent to the meeting reported here, the National Marine Fisheries Service in a letter dated December 3, 1979, responded to the National Park Service's request for a Section 7 consultation. A copy of the NMFS's response is provided in Appendix D of this report.
Humpback whales (_Megaptera novaeangliae_) inhabit the inland waters of southeast Alaska, including Glacier Bay during the summer months (June-August). In the years from 1967 through 1977, 20 to 25 individually recognizable whales were observed feeding in Glacier Bay. In 1978, the whales entered the bay but left earlier than expected. In 1979, only a few humpbacks entered Glacier Bay. The limited information available suggests that increased human activity in the Bay may have been responsible, at least in part, for the observed shift in distribution. Increased human use of coastal waters is not limited to Glacier Bay and the movement of humpbacks from Glacier Bay to areas outside the Bay may be symptomatic of a larger problem.
The purposes of this meeting were: (1) to review available information concerning the nature and possible causes of the movement of whales from Glacier Bay; (2) to review present and planned research and management actions relating to humpback whales in Glacier Bay and southeast Alaska; and (3) to identify additional research or management actions that may be necessary to conserve and protect the North Pacific population(s) of humpback whales.
The meeting was held on the 12th and 13th of October 1979, at the College of Fisheries, University of Washington, Seattle. The meeting agenda is included as Appendix A. Individuals who made formal presentations at the meeting are identified on the agenda. A list of the meeting attendees, their organizations, addresses, and telephone numbers are listed in Appendix B.
