Ocean Power wins grant for Australian wave project (Reuters, Nov. 6, 2009)
Renewable energy firm Ocean Power Technologies has won a A$66.5 million ($61 million) grant from the Australian government for a project set to be one of the first to generate power from waves on a utility scale.

Robot fish to swim in schools and test water quality (Mother Nature Network, Nov. 2, 2009)
Engineers at Michigan State University are currently developing robotic fish which can be coordinated to swim in schools, maneuver in moving water, and keep an eye on water pollution in our oceans, lakes and rivers. The research is yet another instance of nature inspiring technology which is more adequately suited to navigate real situations.

Probe to track warming's effects on water (Discovery News, Nov. 2, 2009)
Hoping to untangle a key mechanism by which Earth warms and cools, a new satellite will for the first time make ongoing measurements of the saltiness of Earth's seas and the water content of the land.

Ocean Power Technologies completes successful trials of underwater substation pod (Reuters, Nov. 2, 2009)
Ocean Power Technologies, Inc. announces the successful completion of trials of its Underwater Substation Pod ("USP") product in Spain. The USP, based on the Company's proprietary design, has been developed to facilitate the collection, networking and transforming of power and data generated by up to ten of its PowerBuoys for transmission to a shore-based electricity grid by one subsea power cable. It has been built as an open platform, and can therefore provide "plug and play" connectivity for any offshore energy device linked to it.

Cleaning up polluted harbors with greener ships (TIME, Oct. 27, 2009)
The image of the old wooden junk with orange sails is ubiquitous in Hong Kong lore. It's on matchbooks, advertisements and postcards in this famous port city, but the traditional wind-powered Chinese boat cruising Victoria Harbor is a rare site these days. The reality is a bit less picturesque: The second busiest port in the world is filled with diesel-powered ships, ferries and fishing boats, belching toxins into the infamously polluted Hong Kong skyline.
