Trace fossils from proglacial lake sediments

Boreas, 1974
Trace fossils have been discovered in Middle Pleistocene proglacial lake sediments from St. Albans, Hertfordshire, England. They indicate that this environment was capable of supporting a variety of benthonic animals. The fossils are described and tentatively assigned to several invertebrate groups.

Sedimentation in proglacial Sunwapta Lake, Alberta

Canadian Journal of Earth Sciences, 1981
The hydrologic and limnologic conditions of Sunwapta Lake, a small proglacial lake in the Canadian Rocky Mountains, were investigated with special reference to the sedimentology of this lake. Discharge and suspended sediment concentrations of the inflowing streams were measured to give estimates of sediment input.

Palaeogeographic reconstruction of proglacial lakes in Estonia

Boreas, 2007
This paper describes a Geographical Information System (GIS)‐based palaeogeographic reconstruction of the development of proglacial lakes formed during deglaciation in Estonia, and examines their common features and relations with the Baltic Ice Lake.

Proglacial Lake Eskdale after Sixty Years

Transactions of the Institute of British Geographers, 1965
SIXTY YEARS ago, P. F. Kendall published a thorough interpretation of 'glacial retreat' in the Cleveland Hills,1 and the ideas contained in his two papers on the subject met with little opposition at that time.2 The anomalous valleys, described as overflow channels, were soon recognized in other areas and used as indicators of the former existence of ...

Proglacial Lakes in High Mountain Environments

2018
Lakes are a characteristic feature of glacial landscapes. They are found in the vicinity of current or past glaciers and ice sheets, in high alpine cirques, inner-alpine valleys as well as lowlands. In recent years, new lakes have emerged in glacier forefields and surface areas and volumes of many proglacial lakes are reported to be growing in many ...

Late‐summer thermal regime of a small proglacial lake

Hydrological Processes, 2011
AbstractThis study was motivated by an interest in understanding the potential effects of climate change and glacier retreat on late summer water temperatures in alpine areas. Fieldwork was carried out between July and September 2007 at Place Lake, located below Place Glacier in the southern Coast Mountains of British Columbia.

The electrochemistry of colloidal particles from a proglacial lake

Chemical Geology, 1987
Abstract The electrophoretic properties of colloidal particles sampled from suspended and deposited sediments of an ice-contact proglacial lake were examined as a function of solution composition and particle size. The finest size fraction of the deposited sediment, which is heavily dominated by mica, provided enough material for surface charge ...

Mer de Glace proglacial lake

2001
In the 90th, a lake appears at the front of the glacier Mer de Glace. At the present days, its dimensions are 125 m X 60, with a surface of about 5000m2 and a volume of 30.000 m3. It could be a real danger in case of outburst.The big storm of October 15th produces a spectacular event.

The radiocarbon reservoir effect in proglacial lakes: Examples from Antarctica

Earth and Planetary Science Letters, 2006
Abstract We studied the apparently old radiocarbon ages from lakes in the dry valleys of Antarctica. The radiocarbon reservoir effect in these lakes results from two components: the inherited age and the residence age. The inherited age is derived from input of old carbon, primarily from subsurface melt of adjacent glaciers.

Bathymetry and Sediment Distribution in Proglacial Malaspina Lake, Alaska

SEPM Journal of Sedimentary Research, 1975
ABSTRACT Glaciolacustrine rhythmites are being deposited in proglacial Malaspina Lake, Alaska. Fathometer profiles of the lake bottom depict irregular subglacial topography little modified by lacustrine sedimentation and areas of flat fleatureless topography that are underlain by sequences of graded lacustrine sediments.
