The Southern Ocean carbon sink has been overestimated in the past three decades

Communications Earth & Environment
Employing machine learning methods for mapping surface ocean pCO2 has reduced the uncertainty in estimating sea-air CO2 flux. However, a general discrepancy exists between the Southern Ocean carbon sinks derived from pCO2 products and those from ...

Climatic modulation of surface acidification rates through summertime wind forcing in the Southern Ocean

Nature Communications, 2018
The Southern Annular Mode is a dominant climate variability mode in the Southern Ocean. Using observational data, the authors show a strong climatic modulation of ocean acidification via Southern Annular Mode -related winds.

New records of Morid fishes (Teleostei: Gadiformes) from the southermost tip of South America

Scientia Marina, 1999
Three species of morid fishes were collected during the Expedition Antarktis XIII/4 of RV "Polarstern" at the southernmost tip of South America, on the slope east of Isla Nueva, Southern Chile (ca.

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 ...

Temperature Thresholds Govern Microbial‐Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems

Advanced Science, EarlyView.
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Southern Ocean Warming

Oceanography, 2018
The Southern Ocean plays a fundamental role in global climate. With no continental barriers, it distributes climate signals among the Pacific, Atlantic, and Indian Oceans through its fast-flowing, energetic, and deep-reaching dominant current, the ...

Reframing the carbon cycle of the subpolar Southern Ocean [PDF]

, 2019
Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since it is here that deep, carbon-rich layers of the world ocean outcrop and exchange carbon with the atmosphere.

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas

Advanced Science, EarlyView.
To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

Role of zooplankton dynamics for Southern Ocean phytoplankton biomass and global biogeochemical cycles [PDF]

Biogeosciences, 2016
Global ocean biogeochemistry models currently employed in climate change projections use highly simplified representations of pelagic food webs. These food webs do not necessarily include critical pathways by which ecosystems interact with ocean ...
