An experiment to investigate the directional nature and the possible generation mechanisms for waves on the Arctic Ocean, an ocean almost entirely covered with sea ice, is described. The waves under consideration have periods between 10 and 100 seconds and amplitudes between 0.001 and 2.0 centimeters. In the present work an array of two continuously recording gravimeters 1,240 meters apart was established at drift station ARLIS II. Observed waves with distinct periods were associated with a storm over Siberia. A continuously recording microbarograph sensitive to atmospheric micropressure oscillations in the 10- to 100-second period range was also installed at ARLIS II. Distinct oscillations were observed in this period range having amplitude of from 20 to 400 dynes/sq cm. Power spectra of micropressure records made before, during, and after a storm show that oscillation amplitude is proportional to the period of the oscillation and speed of local winds. Cross correlation between the micropressure records and wave records taken with a gravimeter at the same location as the microbarograph shows a positive correlation between the micropressure waves and the ocean waves. This correlation appears to vary with the direction of the local surface wind. These micropressure waves contained sufficient force to bend the ice and generate the observed water waves. (Author).

The Arctic Ocean is the smallest ocean in the world. Located on the North Pole, it touches Asia, Europe, and North America. For many months, the sun does not rise over the Arctic, and when summer arrives, the ice barely melts! Young readers will enjoy finding out more about this unfamiliar ocean and its impact on the world.

"In the 1990s, researchers in the Arctic noticed that floating summer sea ice had begun receding. This was accompanied by shifts in ocean circulation and unexpected changes in weather patterns throughout the world. The Arctic's perennially frozen ground, known as permafrost, was warming, and treeless tundra was being overtaken by shrubs. What was going on? Brave New Arctic is Mark Serreze's riveting firsthand account of how scientists from around the globe came together to find answers"--Publisher's description

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 68. Human activities in the polar regions have undergone incredible changes in this century. Among these changes is the revolution that satellites have brought about in obtaining information concerning polar geophysical processes. Satellites have flown for about three decades, and the polar regions have been the subject of their routine surveillance for more than half that time. Our observations of polar regions have evolved from happenstance ship sightings and isolated harbor icing records to routine global records obtained by those satellites. Thanks to such abundant data, we now know a great deal about the ice-covered seas, which constitute about 10% of the Earth's surface. This explosion of information about sea ice has fascinated scientists for some 20 years. We are now at a point of transition in sea ice studies; we are concerned less about ice itself and more about its role in the climate system. This change in emphasis has been the prime stimulus for this book.
