Status, Change, and Futures of Zooplankton in the Southern Ocean

Frontiers in Ecology and Evolution, 2022
In the Southern Ocean, several zooplankton taxonomic groups, euphausiids, copepods, salps and pteropods, are notable because of their biomass and abundance and their roles in maintaining food webs and ecosystem structure and function, including the ...

Manganese co-limitation of phytoplankton growth and major nutrient drawdown in the Southern Ocean

Nature Communications, 2021
Residual macronutrients in the surface Southern Ocean result from restricted biological utilization, caused by low wintertime irradiance, cold temperatures, and insufficient micronutrients.

Southern Ocean anthropogenic carbon sink constrained by sea surface salinity

Science Advances, 2021
Observed sea surface salinity constrains past and future anthropogenic carbon uptake in the Southern Ocean. The ocean attenuates global warming by taking up about one quarter of global anthropogenic carbon emissions.

The underappreciated role of anthropogenic sources in atmospheric soluble iron flux to the Southern Ocean

npj Climate and Atmospheric Science, 2022
The atmospheric deposition of soluble (bioaccessible) iron enhances ocean primary productivity and subsequent atmospheric CO2 sequestration in iron-limited ocean basins, especially the Southern Ocean.

Emerging Skill in Multi-Year Prediction of the Indian Ocean Dipole

Frontiers in Climate, 2021
The Indian Ocean Dipole is a leading phenomenon of climate variability in the tropics, which affects the global climate. However, the best lead prediction skill for the Indian Ocean Dipole, until recently, has been limited to ~6 months before the ...

Supercooled Southern Ocean Waters [PDF]

Geophysical Research Letters, 2020
<p>In cold polar waters, temperatures sometimes drop below the freezing point, a process referred to as supercooling. However, observational challenges in polar regions limit our understanding of the spatial and temporal extent of this phenomenon.

High‐resolution multibeam sonar bathymetry of the deepest place in each ocean

Geoscience Data Journal, 2022
Over the course of 10 months, the global Five Deeps Expedition (2018–2019) mapped ~550,000 km2 of seafloor of which 61% comprised new coverage over areas never before surveyed and ~30% was acquired from some of the ocean's deepest trenches and fracture ...

Interannual variations in meltwater input to the Southern Ocean from Antarctic ice shelves

Nature Geoscience, 2020
Ocean-driven basal melting of Antarctica’s floating ice shelves accounts for about half of their mass loss in steady state, where gains in ice-shelf mass are balanced by losses. Ice-shelf thickness changes driven by varying basal melt rates modulate mass
