The deglaciation and neoglaciation of Upernavik Isstrøm, Greenland

Quaternary Research, 2013
We constrain the history of the Greenland Ice Sheet margin during the Holocene at Upernavik Isstrøm, a major ice stream in northwestern Greenland. Radiocarbon-dated sediment sequences from proglacial-threshold lakes adjacent to the present ice margin constrain deglaciation of the sites to older than 9.6 ± 0.1 ka.

Lacustrine sedimentary record of ice-dammed Neoglacial Lake Alsek

Canadian Journal of Earth Sciences, 1989
Neoglacial Lake Alsek is an ice-dammed lake in the southwest Yukon that forms when Lowell Glacier rapidly advances from a side valley to block the Alsek River. A sedimentary record of past fillings and catastrophic drainages is preserved in small lakes lying within the Lake Alsek basin.

Delta progradation and Neoglaciation, Laguna Parón, Cordillera Blanca, Peru

Journal of Quaternary Science, 2005
AbstractThe history of Holocene glaciation serves as an important record of glacier mass balance and, therefore, of climatic change. The moraine record of Holocene glaciation in the tropical Andes, however, is fragmentary and poorly dated. In contrast, increases in the rate of accumulation of inorganic sediment in glacier‐fed lakes have been linked to ...

Onset of Neoglaciation in the Southern Hemisphere

Journal of Quaternary Science, 2000
A review of evidence documenting an early Neoglacial (mid-Holocene) advance of mountain glaciers in South America and New Zealand reveals that of 16 glaciers for which radiocarbon age control exists, only two have associated dates that may approximate the culmination of an advance.

Natural-environment dynamics within the Amur basin during the Neoglacial

Geography and Natural Resources, 2014
We examine the natural-environment development dynamics within the Amur basin during the Neoglacial. The study revealed the opposing directedness in climate humidity changes for different parts of the basin. In the maritime and inland parts, a cooling was accompanied by an increase and decrease in humidity, respectively.

Neoglacial Facies in the Colorado Front Range

Arctic and Alpine Research, 1972

A soil chronosequence from neoglacial moraines in western norway

Geografiska Annaler: Series A, Physical Geography, 1999
A soil chronosequence is presented based upon podzols developed on Holocene moraine crests in the Jardalen cirque complex, western Norway. Simple and inexpensive field and laboratory tests provide information on soil depth development, pH changes, silt/clay translocation and B-horizon reddening and thickness with age.

Neoglacial climate in the Southern Coast Mountains, British Columbia

2008
Palaeobotanical records of Holocene climate change in the southern Coast Mountains identify a cooler/wetter Neoglacial period subsequent to 6600 BP. Geomorphic evidence of alpine glacier advance suggests that there were three distinct cooler/wetter periods during the Neoglacial, but this pattern has not been identified in palaeobotanical studies.
