New atlas of the pacific ocean —
a vital tool for better using the mineral resources of the sea


Through the support of the ISTC, a group of Russian experts has developed a major new geological-geophysical atlas of the Pacific Ocean. This atlas is distinguished from more general oceanographic atlases of the world oceans by its extremely detailed and comprehensive descriptions of the geological structure and geophysical fields of the ocean floor, based on original data with minimum subjective interpretation. The atlas is a vital tool for better using the mineral resources in the seas and oceans, as well as use as a teaching material and reference source for universities. The atlas also provides an important new tool for lawyers and specialists in the fields of international maritime and geopolitics.

Previously Russian experts have developed similar atlases of the Indian Ocean (1975) and the Atlantic Ocean (1990). In response to the increasing need and demand for more information, the Pacific Ocean atlas was developed, concluding the creation of the series of geological-geophysical atlases for the major world oceans. In content and to the atlases of the Indian and


structure, the atlas is virtually identical Atlantic oceans, although the date of completion reflects technological advances and progress in the scale of intensity of research. The objective was to give to a broad range of users a more detailed set of information about the geological and geophysical structure of the Earth. The Pacific Ocean Atlas contains 192 pages, and was published in the fall of 2003. It is under consideration to convert all three Atlases into digital form on CD-ROMs.

More than 240 leading scientists from Japan, USA, Russia, China, the United Kingdom, Germany, France and other countries participated in compilation of the Atlas. In the process of the work on the project, data of some of the most complex areas of the world oceans was collected and analyzed using modern technologies. The atlas could be influential in resolving numerous problems of Earth and Oceanic sciences.

The decision to create the Atlas was made by the Intergovernmental Oceanographic


Commission of UNESCO, and the project was funded by the Japanese Government as Project 1696-00 of the International Science and Technology Center (ISTC). The project was guided by an International Editorial Board and carried out at the Vernadsky Institute of Geochemistry, Russian Academy of Sciences. Additional funding was provided by the Margaret Kendrick Blodgett Foundation, USA, Tokai University and the National Research Institute for Earth Science and Disaster Prevention, Japan. The printing of the Atlas was undertaken by the administration of navigation and oceanography in the Ministry of Defense of the Russian Federation.






A new class of microchip lasers


Laser sources are widely used in telecommunications, industry, medicine, modern audio and video technology. In 2003, over 23 billion US dollars’ worth of lasers and products, of which the major elements are lasers, were produced. Modern technologies have an ever-growing requirement for diode-pumped microchip lasers, which have such merits as miniature size, low energy consumption, high efficiency and reliability. However, a problem that has until recently remained unsolved concerned the creation of microchip lasers that simultaneously generate short (trillionth


fractions of a second, 10-11—10-10 sec) and long (tens of kW) laser pulses. Microchip lasers with such features have especial potential for applications in medicine, biology and environment protection.

A group of 35 Belarus scientists from the Stepanov Physics Institute of the Belarus National Academy of Science (25 of who were previously experts in lasers weapons technology) have united under Project B-898, financed by the ISTC, to address this problem. The initial stage of the work commenced in 1999 – 2002 under an ISTC project with


the creation of tunable solid-state lasers. Although this new project, devoted to the development of such microchip lasers, has been underway for less than a year, the researchers have already obtained impressive results. For the first time they are using intracavity pulse compression in microchip lasers, which is based on the effect of forced Raman scattering in crystals. Thanks to this, under an electrical power consumption of 1W, microchip lasers generate repeating pulse sequences with peak power of about 50kW and with a duration of 5ơ10-11 seconds.
