Evidence of Recent Active Volcanism in the Balleny Islands (Antarctica) From Ice Core Records

نویسندگان

چکیده

Volcanism can play a key role in modulating climate; however, lack of historical records has limited our comprehension Antarctic volcanism and its on the cryosphere. Remote sensing provide insight into active Antarctica during satellite era, although evidence is often inconclusive. Here, we use independent from ice cores to validate one such potential volcanic eruption sub-Antarctic Balleny Islands 2001 CE. Multiple downwind site, record elevated input sulfate, microparticles, presence tephra, coincident with eruption. In-phase deposition products confirmed rapid tropospheric transport emissions small-to-moderate, local 2001. Air mass trajectories demonstrated some air parcels were transported over West sheet core sites at time eruption, establishing route for sheet. The data presented here previous remote observations confirms event This newly identified provides case study recent volcanism.

Ice Core Records of Recent Climatic Variability: Grigoriev

Ice cores, 16.5 and 20-meters in length, were recovered under the auspices of a cooperative USSR US glaciological research program on the Grigoriev and It-Tish ice caps in the Tien Shan, Central Asia. These have been analyzed for microparticle concentrations and size distributions, stable isotopic ratios (o18Q and 80), selected chemical species, and Beta radioactivity. The 1)18Q records reveal ...

High Resolution Ice Core Records of Late Holocene Volcanism: Current and Future Contributions from the Greenland PARCA Cores

A suite of spatially distributed, multi-century cores collected since 1995 under NASA's Program for Arctic Regional Climate Assessment (PARCA) provides an excellent archive of volcanic emissions reaching Greenland. As records of equiv­ alent quality from higher accumulation sites in Antarctica become available, their integration will produce a richer, better temporally constrained and more clim...

Corrigendum: Possible recent warming hiatus on the northwestern Tibetan Plateau derived from ice core records

Many studies have reported enhanced warming trend on the Tibetan Plateau (TP), even during the warming hiatus period. However, most of these studies are based on instrumental data largely collected from the eastern TP, whereas the temperature trend over the extensive northwestern TP remains uncertain due to few meteorological stations. Here we combined the stable isotopic δ(18)O record of an ic...
