By combining the scientific powerhouses of genetics and geology, University of Otago researchers have identified a new area of coastal uplift, which had been hiding in plain sight.
The Department of Conservation is looking at the decline of 'old growth' kelp beds along the Coast Road and the effects of the marine heatwave on its five marine reserves on the West Coast.
Repeated marine heatwaves have seen most 'old growth' kelp beds along the Coast Road between Greymouth and Westport disappear or dwindle in the past 20 years.

A University of Otago study has revealed how earthquake upheaval has affected New Zealand s coastal species.
Lead author Dr Felix Vaux, of the Department of Zoology, says earthquakes are typically considered devastating events for people and the environment, but the positive opportunities that they can create for wildlife are often overlooked.
For the Marsden-funded study, published in
Journal of Phycology, the researchers sequenced DNA from 288 rimurapa/bull-kelp plants from 28 places across central New Zealand. All specimens from the North Island were expected to be the species Durvillaea antarctica, but unexpectedly 10 samples from four sites were Durvillaea poha - about 150 km from the nearest population on the Kaik?ura Peninsula, Dr Vaux says.
