Antarctica

It’s now day 18 on board the RV Tangaroa and spirits are as high as ever. After seven days of amazing weather and a lot of successes with the blue whale work in the northern Ross Sea we have decided to put the last three days allocated to this scientific objective on hold for later in the trip, and to head south to start our third scientific objective which is the demersal trawl survey.

NIWA voyage leader Dr Richard O’Driscoll updates the Tangaroa’s encounter with the planet’s largest living beings – the Antarctic blue whales – and discovers what’s on their menu.

We have now said goodbye to the towering cliffs and vast glaciers of the Balleny Islands and have been heading southeast tracking blue whales by following their low frequency calls. Yesterday we broke into the polynya that is the Ross Sea. The fantastic weather is following us - making it easy to appreciate this surreal part of the world.

The first objective of the New Zealand- Australia Antarctic Ecosystems Voyage was successfully achieved with the completion of the research at the Balleny Islands.

It’s now day 8 at sea and day 3 at the Balleny Islands. The Balleny Islands are a group of volcanic Antarctic Islands situated at 67 degrees south. They are mostly barren rock, with steep cliff faces and covered by massive glaciers, but they are also home to some incredible marine wildlife!

On day five at 9:07 am we all held our breath as we passed 60 degrees south.

Scientists and crew on board Tangaroa are getting their first taste of the deep South’s breath-taking environment as the vessel crosses the 60th parallel, the northern limit of the Southern Ocean.

Voyage leader Richard O'Driscoll reports on voyage progress so far as RV Tangaroa enters the CCAMLR zone.

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.

Our 42 day adventure to Antarctica aboard NIWA’s RV Tangaroa is just beginning! My name is Blake Hornblow and I am a 2014 Blake NIWA Science Ambassador.

Being selected as one of the two 2014 Blake NIWA Science ambassadors is the most incredible opportunity ever. I still remember the phone call at uni late into second semester last year.
