Discusses: (1) the physics of ice formation; (2) growth, melting, and regrowth of ice; (3) ice distribution; (4) ice movement; (5) the marginal ice zone; and (6) observations of ice dynamics. (JN)

Examines remote sensing of the arctic seas by discussing: (1) passive microwave sensors; (2) active microwave sensors; (3) other types of sensors; (4) the future deployment of sensors; (5) data buoys; and (6) future endeavors. (JN)

The continuing controversey over offshore oil/gas has given impetus to searching for domestic energy alternatives. The need for and types of several alternative sources are discussed. Indicates that the United States needs to pursue both offshore and other domestic liquid-fuel sources if it is to avoid becoming increasingly dependent on imports.…

Estimates of undiscovered oil resources are developed in two general ways: historical-trend analysis and geological analogy. Each of these methods is discussed. Indicates that only well-defined and repeatable methods project a rather bleak future for United States oil discovery. (JN)

New seismic techniques have been developed recently that borrow theory from academic institutions and technology from industry, allowing scientists to explore deeper into the earth with much greater precision than possible with older seismic methods. Several of these methods are discussed, including the seismic reflection common-depth-point…

Describes acoustical systems utlilized for mapping ocean floors. (SL)

Presents an interpretation of geological and geophysical data, which provides a summary of the structural and sedimentary history of the United States Atlantic Margin. The importance of an understanding of the development of the outer continental shelf to future hydrocarbon exploration is detailed. (BT)
