Two major meltwater events are documented in cores from the NW Labrador Sea. These meltwater events coincide with Heinrich (H) layers 1 and 2 from North Atlantic sediments. The AA. hypothesize that δ18O records from these sites close to the former
ice margin should indicate the largest depletion due to meltwater of all North Atlantic sites.

The factors influencing surface denudation by meltwater are bedrock and soils| weather| relief/slope conditions, exposure| anthropogenic activity. Landforms are linked to the combination of geomorphic processes. (DLO).
Dissolved oxygen variations in Alpine glacial meltwaters
Chemical erosion ; Geochemistry ; Glacial features ; Glacier ; Meltwater ; Mountain ; Oxygen ; Switzerland ; Valais
Recent models of chemical weathering in alpine glacial meltwaters suggest that sulphide oxidation is a major source of solute in the distributed component of the subglacial hydrological system. The O2 content of glacial meltwaters depends
The AA. discuss the results of diatom analyses of 4 cores located in different marine settings of the Skagerrat-Kattegat. The AA. focus on how meltwater from the Baltic Ice Lake influenced the oceanography of the Skagerrak-Kattegat. The meltwater
The aim of this paper is to illustrate and describe the meltwater features associated with this expanded Antarctic Ice Sheet that overrode the Transantarctic Mountains. The AA. start by outlining the pattern and process of the long-term landscape
evolution of the mountain blocks in southern Victoria Land. They then turn to the meltwater features indicative of overriding.

A 9.4 m ice core and meltwater were collected in 1995 and 1996 at the glacigenic Galena Creek rock glacier in Wyoming's Absaroka Mountains. The results of the analyses are compared to those from the ice core and meltwater at the Upper Fremont
Glacier to better determine the origin and relative age of the Galena Creek meltwater and ice core. The meltwater from the Galena Creek rock glacier is composed primarily of melted surface snow and rain water rather than melted glacier ice, supporting
A wide range of temporal scales of variability exists in suspended sediment and turbidity records from proglacial meltwater streams. These variations and their causes are illustrated in this paper using data from the stream draining the Haut Glacier

Meltwater flooding in the valley train of the Bas Glacier d'Arolla, (1986 and 1987) produced significant changes in channel form. The general channel response involved switching from a single thread, low sinuosity stream to a wider channel
with zones of braiding. During floods spatial variations in channel adjustment were considerable and contrasts in channel change during different floods were very marked. Meltwater floods cause periodic sediment flushing events which are not necessarily
Suspended sediment transport in glacial meltwater during the initial quiescent phase after a major surge event at Kuannersuit Glacier, Greenland
Cold area ; Glacier ; Greenland ; Ice breakup ; Meltwater ; Sediment transport ; Suspended load
This paper describes a rough estimate of the suspended sediment transport in the bulk meltwater evacuated from Kuannersuit Glacier during the summers of 2000 and 2001, where the drainage system is probably still developing after a major surge event
, which occurred in 1995-98. The focus will be upon relations between sediment transport and meltwater discharge and a comparison of the sediment evacuation from other glaciers of Greenland and High Arctic regions.
Proglacial suspended sediment transport was monitored at Haut Glacier d'Arolla, during the 1998 melt season to investigate the mechanisms of basal sediment evacuation by subglacial meltwater. The AA. use regression analyses to rigorously constrain
evacuation by subglacial meltwater. The wider geomorphic implications of these mechanisms are also discussed.

This article reviews the nature of meltwater runoff models and the variety of ways in which key functional tasks necessary in any such model have been implemented by different modellers. Modelling issues and alternative solutions are exemplified
with reference to 2 widely used but contrasting models (HBV and SRM). This review therefore attempts not just to describe meltwater models but also to show how their variety reflects wider debates in environmental modelling. The emphasis is on seasonal snowmelt
lakes receiving glacial meltwater is discussed. Sediments from four lakes receiving glacial meltwater are discussed, and then compared with sediments from a lake not receiving glacial meltwater. Characteristic differences were observed in the inorganic
