NIWA’s smaller research vessel, Kaharoa, leaves Wellington tomorrow (Thursday 21 April) on a 2-month voyage to deploy high-tech 'Argo' floats all the way to Hawaii and back.
Already, the crew of Kaharoa have deployed more Argo floats (141 so far) than any other vessel in the world. By the end of this trip, they will have deployed over 200 floats and clocked up over 40,000 nautical miles on Argo missions. That is almost the equivalent of sailing to the UK and back twice. (A round trip to the UK is approximately 24,000 nautical miles.)
Go to the east coast of the North Island, and the climate will be about 1.2 degrees Celsius warmer, on average, than at the same latitude on the west coast.
The reason: subtropical water brought across the Tasman Sea on an ocean current known as the Tasman Front. It’s an extension of the East Australian Current – the playground of surfing sea turtles in the movie, Finding Nemo.
NIWA’s research vessel Tangaroa leaves Wellington tomorrow tonight for the Southern Ocean on one of New Zealand’s largest oceanographic research surveys. The 30 scientists on board, from 17 organisations in 6 countries, will study how the ocean controls climate through the uptake and release of crucial greenhouse gases such as carbon dioxide.
A New Zealand research vessel will set sail from Wellington Harbour this Sunday bound for Chile as part of a major international project to understand and predict the phenomena influencing the world’s climate.
Scientists thought they had seen the last of a drifter buoy lost during an experiment in the Southern Ocean in 1999. But to their amazement, the buoy has turned up halfway around the world in the Falkland Islands – albeit looking a little worse for wear.
New Zealand’s marine and freshwater environments are extremely important for our economic and social welfare, but they are under constant pressure from human uses and introductions of new invasive species.
There are more than 150 exotic marine species in New Zealand’s coastal waters already, and at least one new species arrives every year according to a report in NIWA’s new Aquatic Biodiversity & Biosecurity newsletter, published today.
