Ice in the Sea 



strait is only completely ice-free from July to the end of September (Hegemann, 

 1890; ScHULZ, 1911). To the south and south-west of the Lorenz Island along the 

 east coast of Asia the ice season is still very long; in the Tartar Gulf (between the con- 

 tinent and Sakhalin, 52° N.) it lasts through half the year and in the Gulf of Vladi- 

 vostok (43° N.) 3 months. The climatic conditions of the neighbouring continent with 

 its monsoon-like winds blowing oft' the land carry a strong continental type of cU- 

 mate well out over the ocean, and even in spring when the land already warms up, 

 the cold ocean currents along the coast prevent the break-up of the ice. Ice is still 

 present in the inner parts of the Okhotsk Sea in May and the last only disappears in
