 does not support significant changes in the environment between Winnetka and 

 Lake Forest Members, this analysis may have been biased by small sample 

 numbers. (Author).

 Change Associated with South Atlantic Aptian Salt Deposition," Marine Geology . 

 Vol 83, pp 309-312. 



Catastrophic filling of the kind of sub-sea-level depression commonly 

 formed during ocean opening and ocean closing is the only mechanism, other 

 than glacial eustasy, capable of rapidly lowering sea-level (i.e., within 

 10' - 10" years). Aptian evaporites overlying oceanic crust on both sides of 

 the South Atlantic between the Walvis Ridge and the Niger Delta were deposited 

 in such a basin by repeated spilling of ocean water. The final flooding of 

 the South Atlantic north of the Walvis Ridge extracted about 14 X 10* km' of 

 sea water from the world ocean and effected about 10 m. A corollary of our 

 interpretation is that if the catastrophic sea- level lowerings during the 

 Mosozoic era have amplitudes substantially greater than 10 m (e.g.,- 100 m) , 

 then a glacial mechanism to explain them would seem inescapable although the 

 stratigraphic record has not yet yielded any evidence of such glaciation.

 Island, New York, U.S.A.; Response to the Expected Rise in Sea-Level," 

 Northeastern Environment Science . Vol 6, No. 1, pp 1-22. 



Rapid and systematic changes characterize the history of the barrier 

 beaches and islands of Long Island. Several long-term trends are clear: 

 first, westward-drifting littoral currents, flowing past the barrier beaches 

 and islands of Long Island's south shore, are causing the entire barrier 

 system to relocate downdrift (migration). At the same time, the barrier 

 system is responding to the gradual rise in sea- level by moving landward 

 (translocation). As a result, the actual shoreline is recessing (moving 

 landward) at an average of about three ft per year. (Modified Abstract).

Paleogeographic maps showing reconstructed environments of the Eurasian 

 Arctic shelf and coastal zone during the last glacial maximum were compiled. 

 The reconstruction shows conspicuous difference between eastern and western 

 sectors of the Arctic shelf of Eurasia. Large glaciers existed in the west 

 while the eastern Arctic shelf was an emerged ice- fee lowland dominated by
