The Changing Carbon Cycle in the Southern Ocean [PDF]

Oceanography, 2012
Various human activities, including fossil fuel combustion and forest clearing, emit about eight petagrams (or billion tons) of carbon in the form of CO2 into the atmosphere annually.

Mechanisms of Interannual Variability of Ocean Bottom Pressure in the Southern Indian Ocean

Frontiers in Marine Science, 2022
The study of ocean bottom pressure (OBP) helps to understand the changes in the sea level budget and ocean deep circulation. In this study, the characteristics and mechanisms of interannual OBP variability in the Southern Indian Ocean are examined using ...

A change in the relation between the Subtropical Indian Ocean Dipole and the South Atlantic Ocean Dipole indices in the past four decades [PDF]

Atmospheric Chemistry and Physics, 2023
We utilized the global atmospheric reanalysis ERA5 and reconstructed sea surface temperature (SST) data from 1979 through 2020 to examine the stability of the relationship between the SST oscillations in the southern Indian Ocean and the Atlantic Ocean ...

Evaluation of MITgcm-based ocean reanalyses for the Southern Ocean [PDF]

Geoscientific Model Development
Global- and basin-scale ocean reanalyses are becoming easily accessible and are utilized widely to study the Southern Ocean. However, such ocean reanalyses are optimized to achieve the best model–data agreement for their entire model domains and their ...

Microbial ecology of the Southern Ocean

FEMS Microbiology Ecology, 2022
AbstractThe Southern Ocean (SO) distributes climate signals and nutrients worldwide, playing a pivotal role in global carbon sequestration. Microbial communities are essential mediators of primary productivity and carbon sequestration, yet we lack a comprehensive understanding of microbial diversity and functionality in the SO.

The Southern Ocean

, 2017
This chapter highlights how satellite altimetry has helped to illuminate the circulation and dynamics of the Southern Ocean and shows how altimetry has been used to identify the position of the Antarctic Circumpolar Current fronts. It describes the use of altimetry to characterize the four-dimensional temperature and salinity structure of the Southern ...

Pliocene to modern Southern Ocean diatom biostratigraphy revised using samples from IODP Expedition 382 [PDF]

Journal of Micropalaeontology
Biostratigraphy is frequently used to generate age models and is significant to understanding the rate and timing of Cenozoic climate change. Records from the Southern Ocean (SO) are particularly valuable in understanding the past behavior of the ...

Sensitivity of Ocean Carbon Sink Estimates to Rare Observations

Geophysical Research Letters
We evaluate the impact of new data in the annual release of SOCATv2024 on air‐sea carbon dioxide (CO2) flux reconstructions. Using the pCO2‐Residual and LDEO‐HPD methods, we reconstruct surface ocean fCO2 based on SOCATv2023 and SOCATv2024.

Highly stratified mid-Pliocene Southern Ocean in PlioMIP2 [PDF]

Climate of the Past
During the mid-Pliocene warm period (mPWP; 3.264–3.025 Ma), atmospheric CO2 concentrations were approximately 400 ppm, and the Antarctic Ice Sheet was substantially reduced compared to today.
