Little is known about the effects of glacier-air interactions on Himalayan glacier mass balance. Until this knowledge gap filled, a reliable projection future changes in glaciers hardly possible. Here, we describe drying effect katabatic winds up-valley summer monsoon flows by creating favorable conditions for local convergence-induced precipitation to occur near fronts. We postulate that retar...

[1] Estimates of 20th Century sea level rise are typically 1.5 to 2 mm/y, with a steric contribution of (0.5 ± 0.2) mm/y. Estimates of the eustatic contribution vary widely between 1.1 and +1.3 mm/y. We attempt an independent estimate of eustatic sea level rise based on the measured freshening of the global ocean, and with attention to the contribution from melting of sea ice (which affects fre...

During the penultimate glaciation vast areas of the Alps were glaciated, with piedmont glaciers protruding into the foreland. In the easternmost part of the northward draining valleys of the Alps, the glaciers did not reach the foreland, but formed valley glaciers confined by the mountainous terrain. This also applies to the Ybbs valley, where samples for luminescence dating out of glaciofluvia...

Abstract Given the substantial groundwater level declines in Central Valley of California, there is an urgent need to supplement recharge systems by implementing managed aquifer recharge. With approximately 170 km 3 (140 million acre-feet) available storage space, water deemed be excess during wet years could spread on ground surface at selected locations allowing it move downward underlying sy...

Geological and geophysical studies in complex valley troughs provide a key record for the reconstruction of paleoenvironmental conditions during Quaternary. Here we present study sedimentary infill El Cervunal kame or trough (Sierra de Gredos, Iberian Central System) by means combined interpretation near-surface techniques supported geomorphological borehole data.

A detailed understanding of microbial ecology in different supraglacial habitats is important due to the unprecedented speed of glacier retreat. Differences in bacterial diversity and community structure between glacial snow and glacial soil on the Chongce Ice Cap were assessed using 454 pyrosequencing. Based on rarefaction curves, Chao1, ACE, and Shannon indices, we found that bacterial divers...

Abstract. Alpine glaciers in the western United States are often associated with late Holocene Little Ice Age (LIA) advances. Yet, recent studies have shown many of these glacial landforms remnants latest Pleistocene retreat only most cirque-proximal moraines preserving LIA activity. Additionally, timing and magnitude advances during Neoglacial–LIA interval remains uncertain, presumed maximum e...

An important paradigm in geomorphology is paraglacial sedimentation, a phrase first used almost 40 years ago to describe reworking of glacial sediment by mass wasting and streams during and after continental-scale deglaciation. The concept has been extended to include nonglacial landforms and landscapes conditioned by glaciation. In this paper we apply the paraglacial concept to volcanoes in so...
