Rnz: Our Changing World

With its steep sides, forested slopes and heavy rainfall, Fiordland has interesting ecosystems both above and below the water. Below the surface of the inner fiords, a variety of sponges, corals, and other filter-feeding animals cling to the cliff-like reefs. Claire Concannon heads to Doubtful Sound with a research team who are habitat-mapping the fiords to better understand what’s there, and how things are changing over time. They are also investigating the resilience of its iconic black corals to local landslides and marine heatwaves.
