Oceans

One of the major consequences of climate change is rising global sea levels.

RV Tangaroa is New Zealand’s only ice strengthened and dynamically positioned deep-water research vessel.

An unavoidable delay in a research ship’s voyage to Antarctica resulted in some surprising and important findings about the behaviour of emperor penguins.

The coldest seawater on earth could help scientists understand why Antarctic sea ice is growing in a warming world

Hull-mounted on the RV Tangaroa, the EM302 multibeam echosounder maps the seafloor using a fan of 288 acoustic beams, producing up to 864 soundings per ping in dual swath mode, providing 100% coverage of the seabed.
