Researchers have mapped the path of a giant submarine avalanche that tore through the Agadir Canyon — a deep trench in the Atlantic seafloor off the coast of Morocco — 60,000 years ago.

Torrential rainfall, damaging wind gusts, and severe thunderstorms were lashing the U.S. regions on Tuesday afternoon.

Thanks to Tharp’s hand-drawn renditions of the ocean floor, I can imagine a walk across the Atlantic Ocean bottom from New York City to Lisbon.

Ocean explorers have long tried to chart the contours of the seafloor, but today's maps still pale in comparison to those of distant planets.

Cassano said Deep Energy deployed a submersible but it was only able to reach a depth of 8,858 feet. The Titan’s debris was located on the seafloor about 12,500 feet underwater. Pelagic’s team ...

An ultra-detailed map of the ocean floor uses gravity-based data collected by satellite. NASA and CNES launched the satellite to survey Earth’s surface water.

It’s part of a long-term effort, funded by governments and nonprofits around the world, to map the entire seafloor for the first time. And it’s got major global economic implications.

"It's crazy to think that we don't have a complete map of our planet," one researcher involved in a project to map the entire seafloor by 2030 told Live Science.

Golden State Wind will start sound surveys to map the seafloor in the Morro Bay Wind Energy Area off the coast of San Luis Obispo County, California.

The California Coastal Commission approved a permit for an offshore wind developer to map the ocean floor in state waters near San Luis Obispo County.

What caused them? Even NOAA's scientists aren't sure. Okeanos Explorer is investigating the Mid-Atlantic Ridge, a largely unexplored area of seafloor that's home to a massive underwater mountain ...
