Riding Waves & Tides to a Cleaner Energy Future
When one thinks of offshore renewable energy, one usually thinks of offshore wind. For the first time progress is being made in the U.S. to develop offshore wind resources. The first steel foundation jacket has been placed in the ocean floor to support the Deepwater Wind project off the coast of Block Island, Rhode Island. (See www.dwwind.com/press/#/1). But recently, progress is also being made in the development of tidal and wave energy resources closer to shore, which are known as marine hydrokinetic or MHK resources.
NOAA Updates Cobscook Bay Area Chart
Northern Maine vessels will be able to navigate more safely around the dangerous Cobscook Bay thanks to an updated version of the area's nautical chart issued by NOAA. The latest chart includes a new detailed illustration-called a "chart inset"-of the waters around Falls Island, providing safer passage for mariners who transit those waters. While NOAA cartographers had updated Chart 13394 (Grand Manan Channel) over the past several years, using depth measurements and obstruction locations acquired during a major hydrographic survey in 2010, a new inset was needed specifically for Falls Island. "Larger, more detailed scale coverage helps mitigate the dangers to navigation in these areas," explained Cmdr. Shep Smith, chief of NOAA Office of Coast Survey's Marine Chart Division.
Coast Guard, ORPC Tidal Energy Program
U.S. Coast Guard Sector Northern New England (SNNE) crews partner with Ocean Renewable Power Company (ORPC) members to demonstrate the nation's most robust tidal energy program on, Aug. 24, 2010. Gov. John Baldacci, Congressman Mike Michaud and Capt. James McPherson, SNNE’s commander, will unite at Coast Guard Station Eastport to celebrate the first-ever successful implementation of tidal energy at a federal facility. Massive tidal ranges in the ocean waters surrounding Eastport represent some of the largest in the country, rising and falling over 20 feet.
