Impact of geothermal heating on the global ocean circulation [PDF]

, 2001
The response of a global circulation model to a uniform geothermal heat flux of 50 mW m-2 through the sea floor is examined. If the geothermal heat input were transported upward purely by diffusion, the deep ocean would warm by 1.2°C. However, geothermal

Nonlinear El Niño impacts on the global economy under climate change

Nature Communications, 2023
The El Niño-Southern Oscillation (ENSO) is a consequential climate phenomenon affecting global extreme weather events often with largescale socioeconomic impacts.

Pore fluid constraints on deep ocean temperature and salinity during the Last Glacial Maximum [PDF]

, 2001
Pore water records of δ^(18)O and [Cl] from ODP Site 1063A on the Bermuda Rise constrain the change in seawater δ^(18)O and salinity from the Last Glacial Maximum (LGM) to the Holocene to be 0.75±0.05‰ and 2.5±0.1% respectively.

Externally forced symmetric warming in the Arctic and Antarctic during the second half of the twentieth century

Geoscience Letters, 2022
In recent decades, the two polar regions have exhibited strikingly different changes, with much greater warming in the Arctic than the Antarctic. However, the warming asymmetry between the two polar regions is quite small during the second half of the ...

Eddy heat fluxes from direct current measurements of the Antarctic Polar Front in Shag Rocks Passage [PDF]

, 2008
Determining meridional heat flux in the Southern Ocean is critical to the accurate understanding and model simulation of the global ocean. Mesoscale eddies provide a significant but poorly-defined contribution to this transport.

Development of electromagnetic drop weight release mechanism for human occupied vehicle

Scientific Reports
In a human-occupied vehicle (HOV), the drop weight mechanism is used to adjust the ascent/descent motion. In this paper, a new innovation has been developed through the effective integration of a permanent magnet and an electromagnet.

Southern hemisphere eastern boundary upwelling systems emerging as future marine heatwave hotspots under greenhouse warming

Nature Communications, 2023
The biologically productive eastern boundary upwelling systems (EBUSs) are regarded as thermal refugia in a warming climate. However, the authors here show that Southern Hemisphere EBUSs are likely to become hotspots of future marine heatwaves.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

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
