Migration of Walruses ( Odobenus rosmarus) in the Svalbard and Franz Josef Land area
Thirty‐four walruses ( Odobenus rosmarus ) were fitted with satellite transmitters (PTTs) from 1990 to 1993 in order to study the distribution of the population in the Svalbard area. Twenty‐eight were caught at Svalbard and six at Franz Josef Land. All were males except one female caught at Franz Jo...
