Surveying and mapping are providing insights into some of the underwater risks facing New Zealand from landslides and ...

Unlike the sediment-covered deep-sea plains, the above areas have complex topography due to frequent geological activity, which has greatly constrained the accuracy of seafloor classification using ...

A new discovery reveals the immense power of the asteroid that wiped out the dinosaurs, leaving behind 'mega ripples' on the ...

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are ...

The deep-sea, covering more than 60% of the Earth's surface, is a realm of mystery. It hosts a diverse range of geological features, which are all subject ...

Independent researchers from the MiningImpact project and the German Federal Institute for Geosciences and Natural Resources ...

On the abyssal plains, at depths between 3,000 and 6,000 meters, polymetallic nodules are scattered across millions of square ...

As methane migrates from subsurface sediments to the seafloor, it can become trapped as solid hydrates in cold seep environments, preventing its release into the ocean and atmosphere. This study ...

Seagrass meadows, mangroves and kelp forests are carbon sinks. Restoring or protecting them addresses both biodiversity loss and the climate crisis.

“It is like a CAT scan of the Earth, with seismic surveying penetrating deep into the crust to map geological structures, while acoustic mapping maps shallower features like the seafloor depth and ...

By analysing their internal dynamics in detail, scientists can better predict their impact on seafloor infrastructure and refine models of sediment and carbon transport in the ocean.
