Fueling export production: nutrient return pathways from the deep ocean and their dependence on the Meridional Overturning Circulation [PDF]

Biogeosciences, 2010
In the Southern Ocean, mixing and upwelling in the presence of heat and freshwater surface fluxes transform subpycnocline water to lighter densities as part of the upward branch of the Meridional Overturning Circulation (MOC).

Persistent organic pollutants in the Atlantic and southern oceans and oceanic atmosphere [PDF]

, 2017
Persistent organic pollutants (POPs) continue to cycle through the atmosphere and hydrosphere despite banned or severely restricted usages. Global scale analyses of POPs are challenging, but knowledge of the current distribution of these compounds is ...

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

, 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.

Icebergs boost phytoplankton growth in the Southern Ocean [PDF]

, 2008
Icebergs which calve from the Antarctic ice shelves and drift in the Southern Ocean deliver fresh water, dust and minerogenic particles to the surface ocean along the iceberg's path.

Production Country Origin Impact on Soybean Oil Quality

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Previous studies have suggested variability in soybean oil quality depending on geographic origin of the soybeans. In this study, 1035 crude degummed soybean oil (raw oil unrefined except for degumming) samples collected from vessels and crushers over five harvest years (2020–2024) were analyzed for 11 key quality attributes.

Sensitivity of the Atlantic meridional overturning circulation to South Atlantic freshwater anomalies

, 2012
The sensitivity of the Atlantic Meridional Overturning Circulation (AMOC) to changes in basin integrated net evaporation is highly dependent on the zonal salinity contrast at the southern border of the Atlantic.

Impact of hydrothermalism on the ocean iron cycle [PDF]

, 2016
As the iron supplied from hydrothermalism is ultimately ventilated in the iron-limited Southern Ocean, it plays an important role in the ocean biological carbon pump. We deploy a set of focused sensitivity experiments with a state of the art global model

Toward Solution‐Time Advantage With Error‐Mitigated Quantum Annealing for Combinatorial Optimization

Advanced Physics Research, EarlyView.
This paper presents a novel error mitigation technique to address the qubit errors that occur when solving combinatorial optimization problems with quantum annealing. The approach significantly speeds up the computation to reach the global optimum solution for a correlated 3D image segmentation model for material microstructures, demonstrating a ...

Southern Ocean High‐Resolution (SOhi) Modeling Along the Antarctic Ice Sheet Periphery

Geophysical Research Letters
The Southern Ocean plays a major role in controlling the evolution of Antarctic glaciers and in turn their impact on sea level rise. We present the Southern Ocean high‐resolution (SOhi) simulation of the MITgcm ocean model to reproduce ice‐ocean ...

Investigating the role that the Southern Ocean biological pump plays in determining global ocean oxygen concentrations and deoxygenation [PDF]

, 2013
Global ocean circulation connects marine biogeochemical cycles through the long-range transport of nutrients and oxygen with the Southern Ocean (SO) acting as a water mass crossroads. The biological pump in the SO has been shown to play an important role
