  Description:
    Abstract: ABSTRACT: A data file which contains the locations and depths of the stations used to check for the presence of halibut. Each station is spaced no more than 2 kilometers from another station in such a pattern as to allow complete coverage of the lower bay by circular searches (by turning) from each station with a maximum detectable distance of 1 kilometer. One kilometer has been determined to assure close to 100% delectability with the current hydrophones and sonic tags in depths up to 400 meters. PURPOSE: These data were collected as part of an effort to quantify the ecosystem level effects of the commercial harvest of halibut as part of a 10 year study to evaluate the commercial harvest of halibut in Glacier Bay National Park. Knowledge of the home range size and shape as well as the degree of site fidelity was lacking for halibut and was determined to be necessary to evaluate what effects the commercial harvest has on Glacier Bay.

  Access_Constraints: Some Glacier Bay Ecosystem Project data sets may contain data with access constraints. Such areas include sensitive information on the locations of endangered species or cultural artifacts and data which contain private or confidential information. Data sets which are not complete may have access constraints until completion. Please contact the Infromation Management Systems Administrator at the Glacier Bay Field Station for details on any access constraints.
  Use_Constraints: Some Glacier Bay Ecosystem Project data sets may contain data with use constraints. Such areas include sensitive information on the locations of endangered species or cultural artifacts and data which contain private or confidential information. In addition some data sets are collabrative efforts with outside researchers and represent unpublished work for which we request respect for intellectual rights. Some data sets are not complete and if access is given the use may be restricted until completion. Please contact the Infromation Management Systems Administrator at the Glacier Bay Field Station for details on any access constraints.
