The utilization of natural resources in the Bering and Okhotsk Seas is affected by the presence of highly dynamic seasonal sea-ice covers. The means to observe these ice covers during periods of cloud cover and darkness by the Electronically Scanning Microwave Radiometer (ESMR) which operated on the Nimbus-5 satellite from December 1972 to December 1976, has greatly improved our knowledge of their structure and motion. Both of these ice covers are composed of first-year and younger sea-ice types, and both are highly dynamic because they have unconstrained southern boundaries and exist in areas of intense meterologic activity. Sequential ice-concentration maps derived from ESMR imagery show that both ice covers undergo great variation in ice concentration at short time scales. Ice concentration and extent for the years 1973 to 1976, as deduced from ESMR imagery, show significant seasonal and annual variations.
Figures & Tables
The energy and mineral resources of the vast Pacific basin and its neighboring land areas play a vital role in meeting the ever-growing needs of society worldwide. Building on the foundation of a highly successful conference held in 1978, this volume contains 51 of the 135 papers presented there. Subjects included are general and specific in nature--oil, gas, and coal resources; geothermal fields, uranium; tin; evaporites, trace elements; water resources; magma energy and fuels from magma. Geological and geophysical techniques, and also the new tool of remote sending for petroleum and minerals exploration are represented. Tectonics, structure fundamentals, subsurface hazards, international treaties and the law of the deep sea are discussed. Seventeen countries and regions are represented in these papers: Thailand, Nicaragua, the United States, Japan, Peru, Antarctica, El Salvador, Australia, Mexico, Taiwan, New Zealand, China, Chile, Indonesia, Canada, and the Pacific Ocean.
