Fourteen young researchers from across the United States have been studying how climate change is affecting New Zealand, for six weeks on Robert C Seamans, a sail boat with a wet and dry laboratory on board.
They are completing a 12-week programme with the Sea Education Association (Sea) that offers programmes every year for American students to get hands-on experience learning how to sail and carry out research in disciplines from oceanography to history.

She said they were "sailing for science".
One of the students, Julian Swensen, 21, of Oregon, said the programme was a great opportunity for him to explore and travel the world but also complete some of his undergraduate qualification.
The students said they were lucky to make it to Dunedin because previous crews could not make it here because of the weather conditions.

"I was like ‘whoa, I’m awake’."
The students said they had loved being in Dunedin and were looking forward to spending a bit of time in the city after their programme with Sea was finished.
They were keen to explore the peninsula and Tunnel Beach.
