Sinking Dunedin’s flood risk – In the News

Sarah-Jane O'Connor posted in on July 19th, 2016.

Reclaimed land in South Dunedin might be sinking faster than other areas, GNS Science researchers have found, coinciding with a push by the regional council to decide how to handle natural hazard risk in the region. Satellite data from ground stations around Dunedin show land might be sinking about 1mm a year – according to […]

Tūhoe and scientists collaborate on dinosaur hunt – In the news

Laura Goodall posted in on July 7th, 2016.

Ngāi Tūhoe and palaeontologists have teamed up to go digging for dinosaurs and understand more about how these animals lived in New Zealand. The research will focus on searching for fossil remains in streams that flow through Te Urewera National Park, which is managed by Ngāi Tūhoe. “They’re leading the project,” palaeontologist James Crampton from GNS Science […]
