  • Description:
    "A total of seven operational longline sets were conducted during the cruise (Table 2) with catch details by gear provided in Tables 1 and 2. A medical situation and later medevac to Christmas Island, adverse sea and weather conditions plus STCW regulations prevented scientists from conducting operations on approximately 7 days of the cruise (cruise was delayed at the onset by 6 days because of ship's mechanical problems). Nevertheless, scientists and crew were able to perform some cruise activities. Trolling operations were important in capturing blue marlin to be tagged with PSATs. Barbless hooks were tested as to their efficacy to retain bait and thus catch equivalent numbers as regular barbed hooks. Seven light-gathering archival and PSAT tags were affixed to the Oscar Elton Sette's superstructure in the observation platform (above the wheelhouse) to acquire long term ambient light-level data. Scientists (Anders Neilsen, John Sibert, and Mike Musyl) at University of Hawaii/JIMAR are optimizing a new light-based geolocation algorithm. Especially important will be the data collected during the crossing of the Equator and the abilities to improve calculations during Equinox periods. Biological samples for ongoing physiological and hearing studies were obtained from select live fish. Narrative reports on the objectives and results from the various cooperative studies are provided"--Narrative Summary.
