Antarctic climate, Southern Ocean circulation patterns, and deep water formation during the Eocene [PDF]

open access: yes, 2017
We assess early-to-middle Eocene seawater neodymium (Nd) isotope records from seven Southern Ocean deep-sea drill sites to evaluate the role of Southern Ocean circulation in long-term Cenozoic climate change.

Extensive dissolution of live pteropods in the Southern Ocean [PDF]

open access: yes, 2012
The carbonate chemistry of the surface ocean is rapidly changing with ocean acidification, a result of human activities. In the upper layers of the Southern Ocean, aragonite—a metastable form of calcium carbonate with rapid dissolution kinetics—may ...

Slowing of the ocean’s deep breath

open access: yesNature Climate Change, 2023
The deepest reaches of the ocean are ventilated by sinking of cold and relatively saline seawater around Antarctica. Observations from the Australian sector of the Southern Ocean reveal a decline in sinking and abyssal ventilation, linked to dropping ocean salinity on the Antarctic shelf.

Greenhouse Warming Weakens the Seasonal Cycle of the Eastern Boundary Upwelling

open access: yesGeophysical Research Letters, 2023
The response of upwelling in the eastern boundary upwelling systems (EBUSs) to anthropogenic climate change has attracted much scientific attention due to its core role in nourishing marine ecosystems.

A Survey of Ocean Simulation and Rendering Techniques in Computer Graphics [PDF]

open access: yes, 2011
This paper presents a survey of ocean simulation and rendering methods in computer graphics. To model and animate the ocean's surface, these methods mainly rely on two main approaches: on the one hand, those which approximate ocean dynamics with ...

Coccolithophore biodiversity controls carbonate export in the Southern Ocean [PDF]

open access: yes, 2020
Southern Ocean waters are projected to undergo profound changes in their physical and chemical properties in the coming decades. Coccolithophore blooms in the Southern Ocean are thought to account for a major fraction of the global marine calcium ...

Observation of near-inertial waves in the wake of four typhoons in the northern South China Sea

open access: yesScientific Reports, 2023
Based on the velocity and temperature data recorded by two acoustic Doppler current profilers (ADCPs) at a mooring system deployed in the northern South China Sea (SCS), this study investigates the characteristics of near-inertial waves (NIWs) induced by

Passive tracers in a general circulation model of the Southern Ocean [PDF]

open access: yes, 1999
Passive tracers are used in an o?-line version of the United Kingdom Fine Resolution Antarctic Model (FRAM) to highlight features of the circulation and provide information on the inter-ocean exchange of water masses.

Deep Learning Improves Reconstruction of Ocean Vertical Velocity

open access: yesGeophysical Research Letters, 2023
Ocean vertical velocity (w) plays a key role in regulating the exchanges of mass, heat and nutrients between the surface and deep ocean. However, direct observation remains difficult due to its small magnitude and large spatiotemporal variability ...

Artic-North Atlantic interactions and multidecadal variability of the thermohaline circulation [PDF]

open access: yes, 2005
Analyses of a 500-yr control integration with the non-flux-adjusted coupled atmosphere–sea ice–ocean model ECHAM5/Max-Planck-Institute Ocean Model (MPI-OM) show pronounced multidecadal fluctuations of the Atlantic overturning circulation and the ...
