Abrupt arid events in the post-glacial (w17.4–10 kyr BP) Dead Sea Basin (DSB) were recorded by significant lake level declines in Lake Lisan and massive deposition of gypsum and salt. Between 17.4 and 16 kyr cal BP, the lake level dropped from its late MIS2 stand of w260 m below mean sea level (m bmsl) to w330 m bmsl, depositing a thick sequence of gypsum. Between w16 and 15 kyr cal BP the lake...

High resolution DEMs obtained from LiDAR topographic data have led to 9 improved landform inventories (e.g. landslides and fault scarps) and understanding of 10 geomorphic event frequency. Here we use airborne LiDAR mapping to investigate 11 meltwater pathways associated with the Tweed Valley palaeo ice-stream (UK). In particular 12 we focus on a gorge downstream of Palaeolake Milfield, previou...

The numerous perennial meltwater ponds distributed throughout Antarctica represent diverse and productive ecosystems central to the ecological functioning of the surrounding ultra oligotrophic environment. The dominant taxa in the pond benthic communities have been well described however, little is known regarding their regional dispersal and local drivers to community structure. The benthic mi...

Abrupt centennial-to-millennial shifts inNorthernHemisphere climate during the last deglaciation are thought to have been triggered by the discharge of large volumes of meltwater and icebergs to the subpolar North Atlantic1. Here we show that meltwater and icebergswere also transporteddirectly from the Laurentide icemargin to the subtropicalNorthAtlantic in a narrow coastal current. We present ...

In glacier-fed systems climate change may have various effects over a range of time scales, including increasing river discharge, flood frequency and magnitude. This study uses a combination of empirical monitoring and modelling to project the impacts of climate change on the glacial-fed Middle Fork Toklat River, Denali National Park, Alaska. We use a regional calibration of the model HBV to ac...

The timing and magnitude of millennial-scale thermal oscillation in the equatorial Atlantic during the last glacial and marine isotope stage 3 have been perceived as merely a response to meltwater-induced perturbations of the northern high latitude climate. The relatively asymmetric distribution of available temperature records has so far impeded testing whether this view is valid across the eq...

Quantifying the contribution of glacier runoff to water resources is particularly important in regions such as High Mountain Asia, where glaciers provide a large percentage of seasonal river discharge and support large populations downstream. In remote areas, direct field measurements of glacier melt rates are difficult to acquire and rarely observed, so hydro-glaciological modeling and remote ...
