It’s day three at sea and things are all humming along nicely. We’ve just passed 50 degrees south and any faint sighting of the mainland is long gone. The next time we will see land will probably be the Balleny Islands in a couple of days.
National Institute of Water and Atmospheric Research (NIWA), Antarctica New Zealand and the Australian Antarctic Division are undertaking a six-week research initiative in the Southern Ocean on areas of importance to humpback and blue whales and Antarctic toothfish.
A video has been produced to show how NIWA and a range of partners are collaborating to understand global ocean acidification and how increasing ocean acidity is affecting shellfish and the aquaculture industry.
NIWA scientists are among a small group working to understand why New Zealand's sea lion population is declining. Using a range of methods, they're finding that the cause of the decline is varied, and includes changes in diet, bacterial infection, low pupping rates and low survival rates.
