Mountains, canyons, plains — these geological features are not only present on land, but also under the sea, where scientists have now charted them in incredible detail in the ocean surrounding Antarctica. The five-year project mapped 18.5 million square miles, and even revealed a new deepest point in the Southern Ocean, a depression lying 7,432 meters (24,383 feet) below sea level called the Factorian Deep. This study and others like it around the world are filling major scientific gaps in our understanding of what the ocean floor looks like, a key part of knowing how to foster ocean health. More mapping also enables us to make an even stronger science-backed case for marine protected areas. If you want to turn this positive progress into action, you can join us today as we call on world leaders to protect Antarctica and secure the largest act of ocean protection in history. We’re close to reaching our goal of 250,000 petition signatures!
What You Need to Know
Bottom trawling is one of the world’s most destructive fishing practices. By dragging weighted nets along the ocean floor — some up to 240 meters wide — bottom trawling devastates coastal habitats, kills marine life indiscriminately, and depletes fish stocks. Just as bulldozing a forest destroys an ecosystem that has taken centuries to grow, bottom trawling decimates the seabed in a single motion, scraping up coral reefs and any other life in its path.
Shockingly, bottom trawling is still permitted in some of Europe’s most fragile underwater ecosystems even though they have been designated as marine protected areas (MPAs).
