Scientists say the topography of the ocean floor is less well known than the surfaces of Mars, Mercury or Venus and that charting the depth and shape of the seabed will help understand the impact ...

Plans to map the entire ocean floor by 2030 are going ahead despite the challenges of the coronavirus crisis, officials leading the project said, with almost a fifth covered so far.

The problem is idealized as interfacial waves propagating on two interfaces of a three-layer density stratified fluid system with large-amplitude bottom topography. The Dirichlet-to-Neumann operators ...

Certain spacecraft carry altimeter instruments that can infer seafloor topography from the way ... rise in different parts of the world, good ocean-floor maps are a must. Much of the data that's ...
