Many of the Pacific Islands are highly dependant on expensive diesel for electricity, which creates a perfect opportunity for offshore renewable energy projects. The Aukland-based firm ARGOenvironmental has begun negotiations with the island of Tongatapu to install a 1-MW oscillating water column (OWC) that collects electricity from turbines driven by compressed air caused by waves. The goal is energy at the cost of around 21 cents per kilowatt hour, which is significantly less than the current cost of 35 cents per kilowatt hour.

Tethys has been constructed on the Semantic MediaWiki (SMW) platform, which is the same open-source software that powers Wikipedia. A competition selects and features one website per month that best makes use of the SMW platform in a creative and effective way. Immediately after Tethys was nominated, it was selected as the "Wiki of the Month" for April 2013. Find out more at http://semantic-mediawiki.org/wiki/Wiki_of_the_Month.

In addition to the new publicly accessible Annex IV information and data on Tethys, the recently released Final Annex IV Report is also available through Tethys. The Annex IV report contains three case studies of specific interactions of ocean energy devices with the marine environment that survey, gather and analyze the best available information in one coherent location.

Last month, the DOE Wind Program announced funding to seven Advanced Technology Demonstration offshore wind projects. Totaling $168 million over six years, the primary goal of these projects are to expedite the deployment of stronger, more efficient and innovative offshore wind power technologies performance while lowering costs. Additionally, the seven demonstrations will help address key challenges associated with installing utility-scale offshore wind turbines, connecting offshore turbines to existing power grids, and navigating new permitting and approval processes.

On October 15, 2012, Pacific Northwest National Laboratory (PNNL) and the U.S. Department of Energy (DOE) hosted the second Ocean Energy Systems (OES) Annex IV Experts’ Workshop in Dublin, Ireland on the environmental effects of marine renewable energy.

Since 1980, the North Atlantic Right Whale (Eubalaena glacialis) population has experienced a rapid decline, mainly due to fishing gear entanglements and collisions with shipping vessels. Prior to 1980 the whaling industry also took its toll on the whales; the North Atlantic Right Whale (NARW) population size is now estimated to be 300-350 individuals and faces a serious threat of extinction.

Twice each year, east Pacific gray whales (Eschrichtius robustus) swim between their breeding grounds in Baja California and their main feeding areas in the Bering Sea. This round-trip swim of about 15,000 to 20,000 km (8100 to 10,800 nmi) is one of the longest known migrations by a mammal {Shelden et al. 2004}. The whales’ migration route is somewhat unusual because it follows very close to the shoreline.
