With accelerated melting of alpine glaciers, understanding the future state of the cryosphere is critical. Because the observational record of glacier response to climate change is short, palaeo-records of glacier change are needed. Using proglacial lake sediments, which contain continuous and datable records of past glacier activity, we investigate Holocene glacier fluctuations on northeastern...

Core MD99-2323 was extracted from the Snorri Drift at a water depth of 1062 m, just south Denmark Strait, and ~120 km Last Glacial Maximum (LGM) margins Iceland East Greenland Ice Sheets. The core chronology (~7.5 to 240 cal ka) is derived radiocarbon dates, marker tephra, paleomagnetic excursion, correlation with North Atlantic δ18O records on Neogloboquadrina pachyderma (δ18ONp). Sedimentatio...

equilibrium-line altitudes (elas) of former glaciers in the zardkuh mountain of the zagros mountain range were reconstructed from glacial-geologic data on former ice limits by using various methods. in the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. the results suggest that ela were depressed 1433 m below to prese...

Thick, late Quaternary sediment sections were recovered at several sites on the leeward slope of Great Bahama Bank during Leg 166 of the Ocean Drilling Program. These sections have paleoceanographic records with potentially high temporal resolution. To make an initial assessment of the records corresponding to the Holocene highstand of sea level, we have identified and dated the sediments from ...

Radiocarbon dating of Late deposits has shown that erosion of old organic materials and their redeposition in younger sediments ages that are too old. Also, the humid climate and leaching pedogenic environment of much of Tasmania translocation humic acids down profile through porous sediments. The humic acids may then be perched by impermeable clay or may be adsorbed/ absorbed by older clay and...

The miniature paleocontinent in the region of São Francisco River valley, eastern Brazil, holds record two different glacial epochs. late Cryogenian Jequitaí Formation from Bambuí Group is up to 100 m thick and covers areas mainly central craton. Evidences for sedimentation are beautifully preserved E-W grooves striations, dropstones within fine-grained rocks, a full set diamictites enclosing r...

The stratigraphic and compositional study of three sediment cores recovered close to the Po River near Ostiglia provides clues on changes in fluvial dynamics at transition from last glacial present interglacial. Upper Pleistocene units are dominated by sands with high content volcanic lithics, denoting supply south-Alpine fluvio-glacial tributary system. Early–Mid Holocene unit, peat-rich barre...

Two cores of Holocene sediment, collected on opposite flanks of the Vanderford Glacier in Vincennes Bay, while contemporaneous sedimentation, have different sediment characteristics, with a relatively lower biogenic content on the western side than on the east. These sedimentological signatures are attributed to differences in circulation patterns. Circulation involves landward flow at depth, b...

The morphology of glacial valley can be described in terms of power law or quadratic equations fitted to valley cross-profiles. These two models are used to study the cross-profiles of 86 valley cross-profiles in the Zardkuh Mountain in order to understand the evolutional patterns of valleys. Assessment of using the power law function indicates that b values for both valley sides range from 1.0...
