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.

There's an email currently being circulated which is allegedly from the Australian Federal Police and about a computer virus. This is a fake and the warning itself is the "virus', and although a time waster is otherwise harmless.
Any virus warning to come through email is almost certainly a fake and should not be forwarded. This particular one has been in circulation since 2006.

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".
