Dunedinite Professor Peter Croot has seen a fair bit of both land and sea during his time as an internationally-respected chemical oceanographer, having lived and worked in the USA, Sweden, Germany, the Netherlands and England before arriving in Galway in 2012. Along with traversing lots of different terra firma, Professor Croot has continued to explore the world's oceans since his early days as a PhD student at the University of Otago, where he remembers battling seasickness aboard the university's research vessel as it charged through morning swells at Taiaroa Head. He's been doing research in the Greenland and Norwegian seas and the Indian Ocean of late, and his previous work has taken him to the oxygen minimum zones of the Pacific and Atlantic and the Antarctic.
