Earth’s protective ozone layer is on track to recover, with scientists predicting that the hole looming over Antarctica will continue to shrink and could fully repair by 2050. Studies have shown that this restoration would shift westerly winds from Antarctica up toward the equator, potentially leading to lower temperatures in the Southern Ocean and consequently helping to protect both marine creatures and coastal communities 🌊 | Source: CNBC

Kelp helps: Canadian scientists are researching the importance of these brown algae in protecting sea creatures from human-made ocean noise that drowns out the natural soundscape. Using sound science experiments and underwater audio recordings, marine ecologist Kieran Cox is exploring how preserving and restoring kelp ecosystems could reduce sensory harm. Sound waves travel faster and further underwater than they do through air, with marine traffic creating a stressful environment for animals trying to navigate the ocean in peace. But kelp forests are helping to “conserve the soundscape,” providing promising field research and insight into the future of this large seaweed. | Source: The Narwhal

It’s official: The blue whale population in California waters has regained 97% of its pre-whaling numbers! These whales were hunted to near extinction in the twentieth century, and remain an endangered species despite efforts to protect them in and beyond the Pacific Ocean. As policy changes and conservation initiatives develop, we’re seeing hopeful steps in the right direction for the recovery of blue whales 🐳 | Source: KarunaNews
