Figure 158. Drift of the Chelyuskin. 



Thus, the general scheme of drift of arctic ice appears fairly clear, and at first glance, 

 simple: from the coast of Alaska, from the North Pole, and from the coasts of the North American 

 Archipelago into Greenland Sea. However, there is very weighty evidence that the ice drift occurs 

 according to a more complex scheme. It is proposed, for example, that the ice drift along the con- 

 tinental slope of Alaska and Asia from east to west is only a part of a broad anticyclonic movement 

 with its center at approximately 83°-85° north, 170°-180° west. Such a supposition was first ex- 

 pressed as a result of the work of the polar expedition on the ship Zarya . Information since re- 

 ceived does not contradict, but to a certain degree even confirms this proposed scheme. 



Figure 160 shows, by means of arrows, surface currents in the Arctic Ocean. For compila- 

 tion of this chart I have used maps of currents of the following authors: Smith (Baffin Bay), Meyer 

 (North Atlantic), Nansen (Norwegian Sea), Berezkin (Greenland Sea), Sakolov (Barents Sea), 

 Kireyev (Kara Sea), Lappo (Laptev Sea), Ratmanov, Gakkel, and Khmyznikov (Chuckchee Sea).
