A project to harness wave energy on the Chatham Islands has been
awarded funding under the government's Marine Energy Deployment Fund,
Energy and Resources Minister Gerry Brownlee announced today.
The proposal put forward by Chatham Islands Marine Energy Ltd
(CHIME), to install a shore-based device to capture wave energy, has
been awarded $2.16 million, subject to conditions, including receiving
resource consent.
The project will see the construction of an oscillating water column
to power two 110 kilowatt Wells turbines. The device will be installed
on the south-west coast of Chatham Island, and will supply electricity
into the island's electricity network. |

An expansive bloom of phytoplankton (single-celled, plant-like organisms) traced colorful swirls across the
South Pacific Ocean between New Zealand (left) and the Chatham Islands
(right) on December 23, 2009. The colors come from chlorophyll and other
pigments that the phytoplankton use to capture light for
photosynthesis. The milky turquoise parts of the bloom may include
phytoplankton called coccolithophores, which have a chalk-like plating that is very reflective.

The Geological and Nuclear Sciences (GNS) tsunami gauge at Kaingaroa
detected a small tsunami (~40 cm) originating from today's magnitude
8.3 earthquake near Samoa. Rather than being of short duration,
abnormal wave heights were recorded for more than three hours.
Dr Willem de Lange from the Department of Earth & Ocean Sciences at Waikao University said that "The Chatham Islands is exposed to a greater tsunami risk than most of New Zealand because the Chatham Rise acts as a wave guide to trap tsunami. The tsunami waves bounce back and forth along the Chatham Rise, resulting in larger waves at either end (The Chathams and Banks Peninsula). Also because of the deep water around the Chathams, they tend to get the tsunami waves first (Travel faster in deep water). This is why the Chathams were the first location where a tsunami warning gauge was installed. We discovered that the initial site at Waitangi was affected by the waves bouncing, which made them even larger at Waitangi. Hence, the gauges are now located at Kaingaroa, which gives a better indication of how large they will be for the rest of New Zealand".
