  ‘Remarkable’ freshwater turtles face quiet decline

  May 28, 202632 minS1

  <p>This is an episode from our new podcast, It Starts With... available on Apple, Spotify and ConnectSci.</p><br><p>If you enjoy this, check out part 2 of our turtles chat on It Starts With... </p><br><p>Australia’s freshwater turtles are some of the country’s most fascinating and under-appreciated animals.</p><p>They can live for decades, survive incredible injuries, help clean river systems and in some cases even breathe underwater through specialised adaptations. But despite how remarkable they are, turtle populations across Australia are quietly declining and most people do not even realise it is happ...

  4500m deep: remote observatory expands climate knowledge

  Mar 22, 202631 minS1

  <p>David Boldeman speaks with CSIRO marine biogeochemist Dr Elizabeth Shadwick about one of Australia’s most important long-running ocean climate observation programs, the Southern Ocean Time Series south of Tasmania.</p><br><p>Anchored in waters around 4500 metres deep, this remote ocean observatory allows scientists to measure how the Southern Ocean absorbs heat and carbon dioxide from the atmosphere, and how these processes influence the global climate system.</p><br><p>Dr Shadwick explains how carbon dioxide moves from the air into the ocean, how physical circulation and deep water formation can store that carbon away from the atmosphere fo...

  How do you give a whale a hearing test?

  Mar 19, 202618 minS1

  <p>Host David Boldeman speaks with ConnectSci science journalist Imma Perfetto about new research that has, for the first time, measured the hearing range of humpback whales in the wild.</p><br><p>The discussion explores why understanding whale hearing is critical, particularly because whales rely heavily on sound for communication, navigation and finding food in the dark ocean environment. </p><br><p>Imma explains that studying Baleen Whale hearing has long been difficult since these massive animals cannot be kept in captivity. This means scientists previously relied on indirect estimates based on anatomy and vocalisation patterns.</p><br><p>...

  How is ocean temperature measured?

  Mar 16, 202622 minS1

  <p>David Boldeman is joined by science journalist Ellen Phiddian to explore a deceptively simple question: how do scientists actually know the oceans are warming?</p><br><p>The conversation unpacks the global network of measurements that allow researchers to track heat across the world’s oceans, from early ship-based observations to modern satellite systems and autonomous Argo floats that dive thousands of metres beneath the surface.</p><br><p>Along the way, the episode explains why ocean heat content is one of the most important indicators of climate change, how scientists distinguish long-term warming from natural variability, and why th...
