MCT Appoints KPMG as Financial Advisers

With Marine Current Turbines' 1MW SeaGen tidal device set to be installed in Northern Ireland's Strangford Lough later this year, and preliminary work underway to develop a commercial tidal farm in U.K. waters within the next three to five years, Marine Current Turbines has appointed KPMG as financial advisers to review all of the company's strategic business options, including an AIM Listing.

Breakthrough for Subsea Compression

Hydro awarded Aker Kvaerner a contract for the Subsea Compression Pilot for Ormen

Lange. This is reportedly a world first for subsea compression. The aim of the project is to evaluate whether a subsea compression station, at approximately 900 m water depth, is a viable alternative to an offshore platform.

Wide-Azimuth, Towed-Streamer Seismic Survey for GOM

WesternGeco said that Shell Exploration will underwrite a major portion of the first explo- ration multiclient wide-azimuth (WAZ) towed-streamer survey in the Gulf of Mexico. The project covers a minimum of 200 Outer Continental Shelf blocks in the central Gulf of

Mexico, about 125 miles off the coast of Louisiana in water depths of 4,400 ft. Seismic data acquisition will begin in mid-July 2006 and conclude as early as December 2006 uti- lizing a unique design co-developed by WesternGeco and Shell.

WHOI Scientists Share Research Findings

Scientists towing an underwater digital microscope across the

Atlantic have found possible missing links to the global nitro- gen cycle, which in turn is linked to ocean productivity. In a recent report in the journal Science, researchers from the

Woods Hole Oceanographic Institution (WHOI) found abundant colonies of Trichodesmium. The multi-celled, fila- mentous organism is thought to play a significant role in the input of nitrogen to the upper layers of the tropical and sub- tropical ocean, nearly half of the Earth's surface. Lead author

Cabell Davis, a senior scientist in the WHOI Biology

Department, and co-author Dennis McGillicuddy, an associ- ate scientist in the WHOI Applied Ocean Physics and

Engineering Department, suggest that nitrogen fixation rates for Trichodesmium may be 2.7 to 5 times higher than previ- ously estimated from traditional sampling.
