Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust transport to high‐elevation Dronning Maud Land (DML) in Antarctica through analysis of the 1300‐year‐old ISOL‐ICE ice core dust record together

Atmosphere drives recent interannual variability of the Atlantic meridional overturning circulation at 26.5°N [PDF]

, 2013
The RAPID-MOCHA array has observed the Atlantic Meridional overturning circulation (AMOC) at 26.5°N since 2004. During 2009/2010, there was a transient 30% weakening of the AMOC driven by anomalies in geostrophic and Ekman transports.

Camélidos, parásitos y ocupaciones humanas: registros paleoparasitológicos en Cerro Casa de Piedra 7 (Parque Nacional Perito Moreno, Santa Cruz, Argentina) Camelids, parasites, and human settlements: paleoparasitological report from Cerro Casa de Piedra 7 (Perito Moreno National Park, Santa Cruz province, argentina)

Intersecciones en Antropología, 2007
Se analizaron coprolitos asignados a camélidos pertenecientes a un nivel arqueológico de ca. 8000 años C14 AP. Mediante técnicas paleoparasitológicas convencionales se identificaron huevos de Capillaria sp., ascarididos, probablemente Nematodirus sp.

Relative Sea‐Level Change, Tidal Evolution and Energy Dissipation Across the Patagonian Shelf Since the Last Glacial Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Tides play a key role in regulating shelf‐sea environments, influencing sediment dynamics, habitat distribution, long‐term carbon burial, coastal hazards, and water quality, with important socio‐economic consequences. Yet the long‐term evolution of shelf sea tides in response to sea‐level change remains poorly understood. We have developed the

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

Discovery and quantification of the Atlantic Meridional Overturning Circulation: the importance of 25N [PDF]

, 2007
Here we present a review of the history of modern understanding of the strength of the Atlantic Meridional Overturning Circulation (MOC), which arguably originates in 1957.

Projections of Atmospheric Moisture Transport Over South America in a Changing Climate

International Journal of Climatology, Volume 46, Issue 2, February 2026.
End‐of‐century (2071–2100) climate projections show significant contrasts in atmospheric moisture over South America, with increased divergence over Northern Chile and Eastern Brazil and stronger convergence over the La Plata and Magdalena basins. Moisture convergence raises risks of extreme rainfall and floods, while divergence intensifies droughts ...
