GAK_Q50.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (20 of 30) (LCC, 50 m, WGS84)
GLORIA data for the Gulf of Alaska Exclusive Economic Zone (EEZ) were acquired during five cruises over a four year period. The first cruise conducted in 1986 (F-1-86-GA) surveyed an area of the north-central mosaic area and covered an area of approximately 40,000 square kilometers (sq km). The seco...
