Tanfilev noted that in 1884 some divers, examining a cutter which had sunk in 1807 on the 

 Copenhagen route, discovered that the cutter and other sunken vessels alongside it were filled 

 with stones, which could only have been carried there by ice.

Section 131. Currents and Fast Ice 



As has already been mentioned, the speed of sea currents usually decreases with depth. In 

 particular, the speeds of coastal currents decrease with depth according to the parabolic law. 



The sea currents extending vertically to the bottom undergo friction not only with the bottom 

 but also with the lower surface of the ice. Theoretically, since the current speeds are equal to
