Antarctic skin temperature warming related to enhanced downward longwave radiation associated with increased atmospheric advection of moisture and temperature

Environmental Research Letters, 2021
We investigate linear trends in Antarctic skin temperatures (temperatures from about the top millimeter of the surface) over the four seasons using ERA5 ensemble mean reanalysis data. During 1950–2020, statistically significant warming occurred over East

Aerobiology in High Latitudes: Evidence of Bacteria Acting as Tracer of Warm Air Mass Advection reaching Northern Antarctic Peninsula [PDF]

Anais da Academia Brasileira de Ciências, 2023
Despite the extent use of geochemical tracers to track warm air mass origin reaching the Antarctic continent, we present here evidences that microorganisms being transported by the atmosphere and deposited in fresh snow layers of Antarctic ice sheets do ...

Short-Term and Long-Term Predictions: Is the Green Crab Carcinus maenas a Threat to Antarctica and Southern South America under a Climate-Change Scenario?

Diversity, 2023
Non-native species can have profound implications on the survival of native ones. This is especially true for some invasive crabs, such as the green crab Carcinus maenas, a native species to the Northern Hemisphere that has been introduced into southern ...

Global southern limit of flowering plants and moss peat accumulation [PDF]

Polar Research, 2011
The ecosystems of the western Antarctic Peninsula, experiencing amongst the most rapid trends of regional climate warming worldwide, are important “early warning” indicators for responses expected in more complex systems elsewhere.

340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core [PDF]

, 2006
Copyright @ 2006 American Geophysical Union (AGU)Precipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of the Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular Mode (SAM)

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

Atmospheric Patterns over the Antarctic Peninsula

Journal of Climate, 2018
Abstract Using clustering analysis for the sea level pressure field of the ERA-Interim reanalysis between 1979 and 2016, five synoptic pressure patterns have been obtained for the Drake area and Antarctic Peninsula (AP) region (45°–75°S, 20°–120°W), and the resulting daily series has been made available to the scientific community.

A 'low-level' explanation for the recent large warming trend over the western Antarctic Peninsula involving blocked winds and changes in zonal circulation [PDF]

, 2004
[1] We demonstrate a mechanism whereby the impact of stronger circumpolar westerly winds on the mountains of the Antarctic Peninsula contributes significantly to the enhanced warming trend observed over its western side in the last 50 years.

Past penguin colony responses to explosive volcanism on the Antarctic Peninsula

Nature Communications, 2017
Changes in penguin populations on the Antarctic Peninsula in recent decades have been linked to environmental factors such as sea ice. Here, the authors show that penguin colony change on Ardley Island, NW Antarctic Peninsula during the last 8,500 years ...
