Rapid environmental assessment

Article Abstract:

The SACLANT Undersea Research Centre in La Spezia, Italy, has actively worked on a research area involving rapid environmental assessment, or REA, since roughly 1996. REA seeks to enhance the process of littoral maritime environmental support by accelerating the gathering, analysis and distribution of environmental information. SACLANT has developed a concept of REA operations that, used in tandem with technologies jointly developed by the research center and other firms, will furnish the communications links that will make REA a reality for military forces at sea.

Dual use of transient detection: protecting marine mammals by passive sonar

Article Abstract:

FWG Kiel researcher Peter Vossen has found, in a study, that marine mammals' voice signals can be localized against even strong stationary noise from different sources by using sophisticated signal processing. His method works purely passively and thus enables sonar operators to ensure that marine mammals are sufficiently far away before switching on high- power sonar signals. Vossen's technique works best within ranges comparable to the array length and the frequency regime for which the array has been designed.

Rapid environmental assessment

Article Abstract:

The Rapid Environmental Assessment (REA) is the SACLANT Undersea Research Centre's research program which is focused on the enhancement of littoral maritime environmental support by accelerating the pace of collection, analysis and dissemination of environmental data. Among the technologies advanced by REA are satellites which can gauge ocean color by using wavelengths used by water-penetrating lasers. These can also recognize seabed objects for Mine Countermeasures activities.
