These include some pristine fragments of ancient ocean floor, plus some very altered remains that are very difficult to interpret. A complex of small oceans, arcs, and microcontinents formed and were rapidly destroyed during the Taconic orogeny (van Staal et al.

The East Sea is a semienclosed backarc basin surrounded by the Asian continent and the Japanese islands. It consists of three deep basins separated by submarine topographic highs such as the Korea Plateau, Oki Bank, and the Yamato Ridge (Figure ).The topographic highs are made of relatively shallow-seated acoustic basements of rifted continental crust and the overlying thin sedimentary.

Another major contribution of still a different sort was the textbook Stratigraphy and Life History (New York, ), written with E. Colbert. The ocean basins are relatively young; most ocean basin rocks and sediments are Cretaceous or younger in age.

A transform plate boundary is characterized by __________. a deep, vertical fault along which two plates slide past one another in opposite directions. The Pacific Ocean will probably disappear, swallowed up by subduction on its margins. The Atlantic will have widened enormously, pushing North and South America into Asia, Indonesia, and Australia.

This new, giant land mass will likely be shoved far to the north by the spreading along the ridges that circle Antarctica, leaving that icy. The lowered oxygen level in the ocean resulted from stimulated algae may be enough to effect the growth of young fishes in the region where UV radiation was increased.

In another study by Kiceniuk and Colbourne (), the oxygen level in the ocean northeast of Newfoundland where cods live was monitored. The result was not encouraging.

Ma   Last week, the New England Fishery Management Council took an important step forward for ocean conservation by agreeing to allocate $, to support fishery research in the struggling groundfish fishery for cod, haddock and flounder.

The Council has funds to support several projects and included bycatch reduction and solutions as themes in the call for research proposals.
