Climate Change And Other Threats To Worlds Freshwater Goliath's

The video follows scientists aboard the Blue Heron as they study large lakes, focusing on Lake Superior. The Large Lakes Observatory at the University of Minnesota conducts research on the biology, chemistry, physics, and geology of lakes worldwide. The video highlights the warming of Lake Superior due to climate change, using tools like robotic gliders. It also covers sediment core studies to understand historical climate changes and a study on nitrate build-up in lakes. The research aims to link regional climate changes to lake conditions, providing insights into freshwater ecosystems.
