‘I turned into a solar nerd’: money and fun were the unexpected benefits of installing panels

The Guardian - Wed, 2024-08-07 15:00

Our former environment correspondent had solar panels installed in 2010 and later added a heat pump. He’s totted up the energy generated and cash saved over the years

Eight Australian sea lions were enlisted to map the ocean floor by sticking cameras with satellite tracking to their backs. Almost 90 hours of footage and 500km later, conservationists hope to have much clearer ideas on how to protect the sea lions.  “I can watch this stuff for hours,” says Prof Simon Goldsworthy. “It’s like the best slow TV ever.

‘Best slow TV ever’: scientists mount cameras on endangered sea lions to map Australia’s ocean floor

The Guardian - Wed, 2024-08-07 14:14

Eight females from two seal colonies have filmed almost 90 hours across more than 500km, helping scientists map 5,000 sq km of habitat

The Australian sea lions glide and dart through underwater tunnels, over seagrass beds and rocky reefs, searching for a meal and dancing with dolphins around a giant bait ball of fish – all the action captured by a camera stuck on their back.

“I can watch this stuff for hours,” says Prof Simon Goldsworthy. “It’s like the best slow TV ever. You just don’t know what you’re going to see next.”
