R/V Miller Freeman
At 215 feet, the Miller
Freeman is the largest of the three vessels used for the Gulf of Alasaka
studies. The Freeman can hold 31 crew and 11 scientists, cruise at 11
knots. Completed in 1967, the vessel was named after Miller Freeman (1875-1955),
a publisher, who was involved in international management of fish harvests.
During this cruise, the Miller Freeman is conducting fish trawls between
Kodiak Island and Yakutat Bay to better determine what biological and
physical factors affect juvenile salmon populations in the Gulf of Alaska.
The study is testing three primary hypotheses about juvenile salmons’
ocean current preferences, association to water temperature and salinity,
and migration routes through the region. Temperature and salinity profiles
are taken at each trawl site as well as zooplankton haul nets. The juvenile
salmons’ diets are being studied in correlation to the zooplankton
distributions. Salmonids are also being identified for hatchery or wild
stock origins, and catch per unit, scientific studies, and predatory factors
are being analyzed to determine the distribution of pink, coho, chum,
and sockeye salmon in the Northern Gulf of Alaska.
