What’s it like to live and work on the frozen ocean? A team of researchers is camping out on the sea ice to investigate the small critters that live on the bottom of the ice, and among the sloshy platelet ice layer just below it. From microalgae to krill, these tiny organisms hold up the big complex food web of Antarctica. Scientists are keen to understand these communities, and how they might shift as the sea ice cycle changes.

Voice of the Sea Ice 02 | Antarctica's heartbeat
Step out on the sea ice just outside New Zealand’s Scott Base with researchers studying the physics of its annual cycle. Each year a massive patch of ocean around Antarctica freezes and then melts again come summer – Antarctica’s heartbeat. In winter, the ice effectively more than doubles the size of this already massive continent, and it plays a huge role in controlling our planet’s climate.Guests:Dr Inga Smith, University of Otago Antonia Radlwimmer, University of OtagoProfessor Wolfgang Rack, University of Canterbury Learn more:Read the article that accompanies this episode, Monitoring and measuring Antarctica's heartbeat.Listen to Physics on Ice from 2021 with Emeritus Professor Pat Langhorne and Dr Inga Smith.Alison Ballance's Voices from Antarctica series from 2020 explores what it’s like to live and work in Antarctica.This series was made with travel support from the Antarctica New Zealand Community Engagement Programme.

Voice of the Sea Ice 01 | A land of ice and ambition
Welcome to Antarctica - a land of ice, extremes, and ambition. From historic expeditions to modern day science projects, Antarctic exploration is a unique, and dangerous, experience. We meet one researcher involved in an epic journey across the largest ice shelf in Antarctica, mapping a safe route through a crevassed landscape for others to follow. Plus, we learn about the different types of ice found in this vast, frozen landscape. Guests:Dr Daniel Price, University of Canterbury and Kea AerospaceNgā Taonga Sound and Vision archival audioLearn more:Read the article that accompanies this episode.Daniel did the route-finding for the SWAIS2C project. Veronika Meduna flew out to the camp in the 2023/2024 season to report on their activities.Daniel has spoken to Morning Report about Kea Aerospace’s work developing a solar-powered aircraftHear about other ongoing research in Antarctica from the latest research season, including investigating new methane seeps, and giant glass sponges.Learn more about living, and working, on the ice in the 2020 podcast series – Voices from Antarctica.This series was made with travel support from the Antarctica New Zealand Community Engagement Programme.

Keeping tabs on Fiordland’s sharks and researching our deep-sea realm
Using acoustic tags and a network of receivers attached to the seafloor, researchers are tracking the movements of sevengill sharks in Fiordland. They want to understand how these apex predators adjust to changing ocean temperatures, particularly during marine heat waves. Plus, an international collaboration involving a high-tech German research vessel is exploring New Zealand’s deep-sea realm.Guests:Eva Ramey, PhD candidate, Victoria University of Wellington Dr Alice Rogers, Victoria University of Wellington Coastal Ecology Lab Dr Kareen Schnabel, NIWA Professor André Freiwald, Senckenberg am Meer Research Institute Dr Cornel de Ronde, GNSLearn more:Read the accompanying article. Listen to this 2016 episode about the Great white sharks of Australia and New Zealand.RNZ journalist Kate Green also hopped aboard the RV Sonne to find out about its technology and capabilities.This is not the first time the RV Sonne has been in New Zealand waters, one previous expedition also involved investigations of underwater volcanoes.Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more.Go to this episode on rnz.co.nz for more details

Recruiting the birds to help reforestation, and investigating ADHD and fidgeting
People with ADHD often fidget more than those without. Why might this be? Does it help them focus? Or distract them further? An Auckland Bioengineering Institute researcher has teamed up with the Mātai Medical Institute in Gisborne to investigate this using advanced MRI techniques. And at Waikereru ecosanctuary, local birds are being enlisted in a trial to help speed up the regeneration of native bush.Guests:Professor Justin Fernandez, Auckland Bioengineering InstituteDr Gil Newburn, Mātai Medical Institute Professor Dame Anne Salmond, Waikereru EcosanctuaryLearn more:Read the accompanying articles: Recruiting the birds to bring back the bush and Why fidgeting might be a good idea.In 2017 Alison Ballance did a story about The 1769 Gardenwhere she spoke to the garden designer, curator and local botany expert.To learn about the Mātai Medical Institute, listen to The advances in MRI coming out of Gisborne from November 2024.The Mātai Medical Institute is also involved in research into recovery post meth addiction, concussion in teenage rugby players, and muscle development in children with cerebral palsy.
