30MTRJuly/August2011 Canada, United States, France, Argentina and Norway. The AURAL- M2 is an autonomous underwater sound recording device for passive acoustic. Powered by standard D? battery, it is used for the listening of methane bubbles, marine mammals life, underwater noise pollution, even the Grand North ice cracking. It is designed to record underwater sounds, pressure and water tempera- ture over a period to one year with total autonomy. It is available in three sizes (for short, medium and long deployment). The Instrumental Oceanographic Buoy is available in optical, meteorological and oceano- graphic parameters. The information it collects is sent to a land station viaUHF modem/satellite or a combina-tion of UHF and internet.Other notable Multi-Electronique products include the Winch Counter, Underwater Camera, Bionet, Sample Counter, MC Data Logger and Vertical Net.

Testing Capabilities (ie. test tanks, boats, pressure cham- bers): Oceanscience is located on the west coast of the U.S. on the Pacific Ocean where all ocean testing is com- pleted. Additional tests are completed at the Oceanscience facilities or at Scripps Institute. Number of Employees: 20 Annual Sales (USD): $3m Since 1998, Oceanscience has developed and manufactured oceano- graphic, hydrographic and hydrologic field equipment and instrumentation. The UnderwayCTD, conceived at Scripps Institution of Oceanography and developed at Oceanscience, was designed to provide quick, research- quality data. The fully portable sys- tem was designed to be set up andmanned by one person. Oceanscience has also launched UnderwaySV, which it had developed in partnership with Valeport Ltd. The UnderwaySV, intended for use by hydrographic sur- veyors, offers profiles to 600m depth while underway at 10 knots and free falling at up to 5m/s. Oceanscience also offers surface buoy mounts and seafloor platform frames for acousticDoppler current profilers (ADCP). Custom applications and design proj- ects from large spar buoys to small sensor packages have been created at Oceanscience with the help of the ocean engineering team. THE MARINE TECHNOLOGY REPORTER 100Established in 1965 as a spin out from Imperial College, London, Chelsea Technologies Group (CTG) has developed a reputation as a designer and manufacturer of innovative sensors and systems for the military and civil oceanographic, environmental, acoustics, medical diagnostic and process control markets. CTG was recently asked to provide sensors to monitor and track the oil released into the Gulf of Mexico following the Macondo inci- dent. Chelseas long established UV AQUAtracka fluorimeter with the new FASTocean Fast Repetition Rate Fluorimeter are now being used to monitor the effects of the oil on the primary productivity of the Gulf. Technology Profile: CTG recently launched the FASTocean system designed to improve the accuracy of primary productivity measurements within diverse natural phytoplankton communities. Applications for this system now include pri- mary productivity measurements, coastal monitoring, iron fertilization experiments, algal bloom detection and the protection of water supplies against accidental or deliberate contamination. Following on from the suc- cessful launch of the Lux range of miniature high performance fluorimeters last year, over 150 units are now in the field with users reporting excellent datasets. Chelsea also has an established range of acoustics transducersincluding hydrophones, projectors, towed arrays and military sonar test & evaluation systems. Chelsea has a history of working with UK and overseas navies and has recently supplied the Sonar 2115 oceanographic system for a fleet wide installation onboard the Royal Navys new Astute class submarines.
