Alaskan Submarine Cables: A Struggle with a Harsh Environment
Reviews the laying, repair and maintenance of telegraph and cable systems, at one time 86 submarine cables, between Puget Sound and Alaska 1901-60. Failures due to entanglement by whales, bruising and mauling by anchors and fishing trawls and various destructive effects of geologic agents on the sea...
