The Influence of Ocean Topography on the Upwelling of Carbon in the Southern Ocean

Geophysical Research Letters, 2021
AbstractThe physical circulation of the Southern Ocean sets the surface concentration and thus air‐sea exchange of . However, we have a limited understanding of the three‐dimensional circulation that brings deep carbon‐rich waters to the surface. Here, we introduce and analyze a novel high‐resolution ocean model simulation with active biogeochemistry ...

Seafloor Topography and Ocean Circulation [PDF]

Oceanography, 2004
Introduction Seafloor topography influences ocean circulation in two basic ways. First, it steers ocean flows. Second, it provides barriers that prevent deep waters from mixing, except within deep passageways that connect ocean basins or in hydraulically controlled overflow regions.

Magmatism Controls Global Oceanic Transform Fault Topography

Nature Communications, 2023
Abstract Oceanic transform faults are fundamental features of plate tectonics, accommodating strike-slip motion between two adjacent mid-ocean ridge segments. The continuations of these faults form tectonically inactive fracture zones, creating the longest ‘scars’ on the Earth’s surface.

Research and application of convolutional neural network in mining area prediction

工程科学学报, 2020
Cobalt-rich crusted deposits are found all over the world’s oceans, and their distribution is closely related to the submarine topography. The determination of crusting area is the basic work for the exploration and mining of these deposits. Many factors

Generating synthetic fjord bathymetry for coastal Greenland [PDF]

The Cryosphere, 2017
Bed topography is a critical boundary for the numerical modelling of ice sheets and ice–ocean interactions. A persistent issue with existing topography products for the bed of the Greenland Ice Sheet and surrounding sea floor is the poor ...

Ocean Barotropic Vorticity Balances: Theory and Application to Numerical Models

Journal of Advances in Modeling Earth Systems, 2023
The barotropic vorticity (BV) balance is fundamental when interpreting the ocean gyre circulation. Here we propose an intercomparison of vorticity equations for the depth‐integrated flow applied to ocean models. We review four distinct variants of the BV

Impacts of mean dynamic topography on a regional ocean assimilation system [PDF]

Ocean Science, 2015
An ocean data assimilation system was developed for the Pacific–Indian oceans with the aim of assimilating altimetry data, sea surface temperature, and in situ measurements from Argo (Array for Real-time Geostrophic Oceanography), XBT (expendable ...

Transfer learning reconstructs submarine topography for global mid-ocean ridges

International Journal of Applied Earth Observations and Geoinformation
Mid-ocean ridges are unique, tectonically active geographical units on Earth that profoundly control the ocean environment and dynamics at the global scale.

Integration of the latest Digital Terrain Model (DTM) with Synthetic Aperture Radar (SAR) Bathymetry

Journal of Degraded and Mining Lands Management, 2021
Topography and bathymetry integration is one of the essential things in providing height data. So far, the topography and bathymetry problems are the lack of height data availability, not up to date, and low vertical accuracy.
