Narobs
A cold and hostile place the Barents Sea. Generally 230m deep and dropping to 600m to the west in a line from Svalbard via Bjørnøya to Norway.
And very much a nightmare for sailors from 1941 to 1945.
My Grand Uncle Olav had multiple trips on a Nortraship, a Knudsen tanker no less.
6 years he sailed, including a few trips to Arkangelsk. We owe them everything.
I think current, oxygen and general marine life has wore down a lot in the Barent Sea. Regardless , wrecks inside Norwegian territory here are classified as War Graves and off limits.
