Alaska Bathymetry: Central Gulf of Alaska Seafloor Changes(pg 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

Seafloor Changes of Central Gulf of Alaska

Katalla Bay Shoreline

Other significant bathymetry changes are more localized. For example, a shoreline accretion of about 600-800 m in Katalla Bay, near the Copper River, occurred between the 1905 (H02768) to 1971 (H09207) surveys, perhaps as a result of heavy sediment deposition in this area (Jeager et al., 1998).
