Since the early 2000s, NIWA has been part of the international Argo programme. Argo floats take the pulse of the oceans, collecting and distributing temperature and salinity observations from a global network of more than 3700 underwater robots.
The sounds of whales and dolphins rarely seen in New Zealand waters have been recorded by a NIWA scientist in a pioneering underwater sound project.
New Zealand’s coast is sculpted by ocean waves. Some wave conditions bring joy to surfers and beachgoers, but, at other times, waves can cause major hazards at sea or along the shore.
