Competing impacts of tropical Pacific and Atlantic on Southern Ocean inter-decadal variability

npj Climate and Atmospheric Science
The observed Southern Ocean sea surface temperature (SST) has experienced prominent inter-decadal variability nearly in phase with the Inter-decadal Pacific Oscillation (IPO), but less associated with the Atlantic Multidecadal Variability (AMV ...

Assessing improvements in global ocean pCO₂ machine learning reconstructions with Southern Ocean autonomous sampling [PDF]

Biogeosciences
The Southern Ocean plays an important role in the exchange of carbon between the atmosphere and oceans and is a critical region for the ocean uptake of anthropogenic CO2.

Gene flow in the Antarctic bivalve Aequiyoldia eightsii (Jay, 1839) suggests a role for the Antarctic Peninsula Coastal Current in larval dispersal

Royal Society Open Science, 2020
The Antarctic Circumpolar Current (ACC) dominates the open-ocean circulation of the Southern Ocean, and both isolates and connects the Southern Ocean biodiversity. However, the impact on biological processes of other Southern Ocean currents is less clear.

High Performance Flexible Optical Fiber Sensor Enabled by Er3+/Yb3+ Co‐Doped near Pure‐Green Upconversion Emission Phosphor for Implantable Temperature Sensing

Advanced Materials Interfaces, EarlyView.
A superior double‐cladding optical fiber temperature sensor (OFTS) is fabricated by utilizing a bright and stable near‐pure green UC phosphor NaLu(WO4)2:Er3+/Yb3+ as sensing material. The OFTS exhibits a high temperature measurement accuracy of 0.155°C at 303 K, excellent measuring repeatability and chemical stability, along with strong resistance to ...

Pathways and timescales of Southern Ocean hydrothermal iron and manganese transport

Communications Earth & Environment
Scarcity of iron and manganese limits the efficiency of the biological carbon pump over large areas of the Southern Ocean. The importance of hydrothermal vents as a source of these micronutrients to the euphotic zone of the Southern Ocean is debated ...

3D Microprinting of Structures with Lanthanide‐Based Fluorophores on Optical Fibers for Multiplexed Sensing

Advanced Optical Materials, EarlyView.
Incorporating lanthanide‐based fluorophores into commercial resists for femtosecond direct laser writing enables a novel platform for multiplexed sensing. Porous, periodic, and solid luminescent microstructures fabricated directly on optical fiber tips are presented.

Glacial heterogeneity in Southern Ocean carbon storage abated by fast South Indian deglacial carbon release

Nature Communications, 2020
A Southern Ocean influences on the carbon cycle is considered a key component of deglacial changes. Here, the authors show spatial differences in glacial Southern Ocean carbon storage that dissipated rapidly 14.6 kyr ago, revealing a South Indian Ocean ...

Mitigating Singlet Exciton Back‐Transfer using 2D Spacer Layers for Perovskite‐Sensitised Upconversion

Advanced Optical Materials, EarlyView.
The efficiency of bulk perovskite‐sensitised upconversion is hindered by parasitic singlet back‐transfer. A 2D perovskite spacer layer is introduced to weaken this loss pathway by increasing the separation between the sensitiser and the emitter. The spacer layer enhances the upconversion efficiency at lower excitation powers and improves the stability ...

Southern Ocean Biological Pump Role in Driving Holocene Atmospheric CO2: Reappraisal

Geophysical Research Letters
Changes in Southern Ocean biological pump efficiency are frequently invoked as a source of glacial/interglacial CO2 variability. It was recently suggested that Southern Ocean biological pump weakening also contributed to Holocene CO2 increase.
