Abstract: Geological and biological features of three of nine Gulf of
Alaska seamounts surveyed by the National Marine Fisheries Service during
the summer of 1979 are compared and discussed. A modified free vehicle
photographic system, which produced the first photographs of the fauna and
substrate on the summits of Patton, Giacomini, and Quinn seamounts, is
described. Interpretations of echo sounding data, a limited number of rock
samples, photographs from the seamount summits, and exploratory fishing
catches are also presented. Geological features described as characterizing the
summits of the three surveyed seamounts seem consistent with similar features
described from other Pacific basin seamounts (Hess 1946, Menard and Dietz
1951, Murray 1941, Palmer 1966). The taxonomic composition of the observed
epibenthic invertebrate fauna, and demersal and benthopelagic fishes, is
discussed. Patton seamount is described as having the greatest taxonomic
diversity. Photographs from the summits of Patton, Giacomini, and Quinn
seamounts are presented.
