Low‐Altitude High‐Latitude Stratospheric Aerosol Injection Is Feasible With Existing Aircraft

open access: yesEarth's Future, Volume 13, Issue 4, April 2025.
Abstract Stratospheric aerosol injection (SAI) is a proposed method of climate intervention in which aerosols or their precursors would be injected into the stratosphere to reduce or halt global warming. It is often assumed that to produce a substantial global cooling, SAI would require a fleet of specially designed high‐altitude aircraft.

Observed interannual variability of the Atlantic meridional overturning circulation at 26.5N [PDF]

open access: yes, 2012
The Atlantic meridional overturning circulation (MOC) plays a critical role in the climate system and is responsible for much of the heat transported by the ocean.

Pore Fluid Origins, Circulation, and Links With Methane Hydrate on the South‐Central Chilean Margin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The chemical composition of marine sedimentary pore waters, notably freshening signals inferred from decreases in dissolved Cl−, have demonstrated a link between methane hydrate accumulation and the circulation of fluids and gases in convergent margin systems.

A New Perspective on Past Export Production in the Subantarctic South Pacific for the Last ∼1.4 Myr

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 2, February 2025.
Abstract Accurate reconstructions of export production in the Subantarctic Zone of the Southern Ocean are crucial for understanding the carbon cycle during Earth's past. However, due to the strong bottom water circulation of the Antarctic Circumpolar Current, sediment redistribution complicates age‐model‐derived bulk mass accumulation rates (BMAR ...

The location of diapycnal mixing and the meridional overturning circulation [PDF]

open access: yes, 2002
The large-scale consequences of diapycnal mixing location are explored using an idealized threedimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong meridional overturning circulation (

Los cabezales líticos tardíos de Tapi Aike (Provincia de Santa Cruz, Argentina): un estudio de las variaciones en forma, tamaño y reducción

open access: yesRevista del Museo de Antropologia
Los enfoques tradicionales suelen basarse en la tipología, que emplea atributos tecno-morfológicos discretos para clasificar los cabezales líticos, lo que tiende a ocultar un componente de variación continua asociado a sus ciclos de vida y procesos de ...
