"A total of 16 operational longline sets were conducted during the cruise with catch details by gear provided in Tables 1 and 2. Seventeen CTD casts were conducted to document vertical characteristics of the water column. Seven of the casts (mostly near dawn, dusk) were specifically designed to aid in a continuing study of light attenuation at depth, particularly at crepuscular times. Six archival tags and one PSAT tag were affixed to the CTD for this purpose. Barbless hooks were tested as to their efficacy to retain bait and thus catch equivalent numbers as regular barbed hooks. Biological samples for ongoing physiological studies were obtained from select live fish. Narrative reports on the objectives and results from the various cooperative studies are provided"--Narrative summary.
