As part of the ongoing effort, a NASA-supported team recently published one of the most detailed maps yet of the seafloor.

A massive deep-sea ravine in the Pacific Ocean has been mapped out in greater detail than any other part of the world's seafloor. The new maps of the "deep-sea Grand Canyon" have a "centimeter-scale ...

An international scientific team recently published a new map of the ocean floor based on Earth’s gravity field, and it is a particularly useful tool. Such seafloor maps can aid submariners and ship ...

Scientists at the Monterey Bay Aquarium Research Institute (MBARI) have created a stunningly detailed seafloor map of the largest submarine canyon off of the US Pacific coast. Using sonar data ...

Oceanographers are using data collected by elephant seals to improve their map of the seafloor on Antarctica’s continental shelf. The new map results from a collaboration between Daniel Costa, a ...

Whirring over a sun-streaked patch of tropical seafloor, a submersible equipped with cameras is helping to provide the most detailed maps ever recorded of underwater shelves and struggling coral reefs ...

Alameda-based aquatic drone-maker Saildrone has returned with a bigger and better version of its unmanned vehicle designed to explore the seas. The newly introduced 72-ft (22-m) Saildrone Surveyor is ...

As it stands, something like 80 percent of the seafloor remains unmapped, despite oceans covering 70 percent of the globe. That would be a lot of terrain for humans to survey, but lately we're seeing ...

New seafloor maps reveal the first clear view of a system of channels that may be helping to hasten the demise of West Antarctica’s vulnerable Thwaites Glacier. The channels are deeper and more ...

– Joint press release of the GEOMAR Helmholtz Centre for Ocean Research Kiel and GEBCO Seabed 2030 – At least twice in the last 20 years, nuclear submarines have collided with previously unknown ...

Marie Tharp, an oceanographic cartographer who drew pioneering maps of the world’s oceans and whose observations from the late 1950s through the 1970s helped scientists reconsider the geology of the ...

Humans have explored an extraordinary variety of strange and harsh environments — from the icy landscapes of Antarctica to the unforgiving surface of the moon. But there's one place right under our ...
