Drought and Algae
Behind the News travels to the Fleurieu Peninsula in South Australia, which has been hit by two big environmental disasters – a drought and a devastating algal bloom which is killing local sea life. We find out what’s been happening and how it’s affecting locals.
Waves supply nutrients to marine ecosystems
This video, along with reflection questions, explores the essential role of waves in marine ecosystems by helping to deliver nutrients that support plankton growth and other marine life, ultimately impacting the health of the ocean environment.
Sound waves measure ocean temperatures
This video and activity explains how researchers use sound waves to measure ocean temperatures, a technique that helps monitor climate change and marine environments by providing accurate, real-time data on temperature changes at various depths.
For the Juniors: Fish from the ocean to table
This video and activities introduces children to the journey of fish from the ocean to their plate, exploring topics such as sustainable fishing practices, the impact of overfishing, and how seafood is harvested and processed. The content aims to educate young learners about marine ecosystems and the importance of making responsible food choices.
Catalyst: Seals help climate research
This video highlights how researchers are using seals to gather data on ocean temperatures, currents, and ice thickness, which are crucial for understanding climate change. The seals help collect valuable information from remote regions that are difficult for humans to access, providing new insights into the state of marine ecosystems and the impacts of climate change.
Dr Karl vs the mysterious giant squid
This video explores the fascinating world of the giant squid, including Dr Karl Kruszelnicki's scientific investigation into its size, behaviour, and mysteries, using engaging explanations to uncover facts about this elusive marine creature.
Elliot and the Surfing Scientist: Salt Water Density Experimen
In this video, the Surfing Scientist demonstrates how salt increases the density of water, influencing how objects float or sink. The experiment encourages students to explore the science of buoyancy and density in a fun and interactive way.
Catalyst: Nautical Robots
Watch the report by Ruben Meerman and discover how more than 3000 'nautical robots', known as argo floats, have been placed in the oceans to collect data on variations in temperature, pressure and salinity.
Exploring Australia’s Seafloor
This video explains how marine scientists map the seafloor and the various uses for these maps. It also introduces unique and mysterious sea creatures found in the deep ocean, exploring the experiences of a marine scientist and their passion for glass sponges, infauna, and bioluminescent animals.
For the Juniors: Exploring under the sea
This video takes you on an underwater journey to discover some of the ocean’s strangest and most fascinating creatures. Learn the incredible way starfish eat and explore the mysterious depths of the ocean, where extreme water pressure makes survival impossible for humans.
