Neoglacial climate in the Southern Coast Mountains, British Columbia
… 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. By …

Palaeoceanographic conditions and palaeoproductivity changes from the sub-Antarctic island South Georgia since the late deglacial, using marine micropalaeontology and geochemistry
… glacial outwash-derived iron. The late Holocene Neoglacial (from ca. 4.2 cal. kyr BP) is characterised by cooling, increased sedimentation, and renewed productivity, consistent with Neoglacial advances. Cooler temperatures caused a northward migration of the SWW towards South Georgia, increasing …

4000 years of environmental and climate change at Eilandvlei : a palynological investigation into the late Holocene palaeoenvironment of the Wilderness Embayment
… three events that typify the late Holocene: the Neoglacial, the Medieval Climate Anomaly and the Little Ice Age. The record also encompasses the arrival of European colonists in the region ca. 1800 AD, marked by the appearance of Pinus, with subsequent notable fluctuations in other taxa, e.g. …

The interaction of climate, tectonics, and topography in the Olympic Mountains of Washington State: the influence of erosion on tectonic steady-state and the synthesis of the alpine glacial history
… growth curve for lichenometric dating of neoglacial moraines is developed and applied to four moraines at the base of Royal Glacier on Mt. Deception. The moraines range in age from 1839±45, 1895±45, and 1963±45, to less than 20±45 years. The estimated equilibrium line altitude (ELA) for …

Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach
… onset of Neoglaciation in eastern Iceland. The Neoglacial expansion of Eyjabakkajökull caused the glacier to begin to surge ca. 2200 years BP. During the last 1700 years, the glacier has surged at a fairly constant periodicity except for the later part of the Little Ice Age (ca. 1600-1900 AD), …

Antarctic phytoplankton and climate change using Holocene sedimentary DNA, fossils and chemical proxies.
… bays. The study interval (~1.5 ka) spans the Neoglacial, the Medieval Climate Anomaly, the Little Ice Age (LIA) and twentieth-century Recent Rapid Warming. There are four aims:. (i) Build new chronologies and multiproxy records of fjord sea ice, sediment input and productivity. (ii) Test the …

A Glacial Sedimentary System in Northwest Spitzbergen
… glacier presence in Signedalen. Evidence of Neoglacial cooling, between approximately 3,000 yr BP and 1,500 yr BP, is found in lichenometric recorckof talus deposits, although precise dating of the inception, and duration of this cooling is problematic. No moraine sediments are recorded from …

Lake and fjord sediments as Late Glacial to Holocene environmental and climate archives of the southernmost Andes at 53°S, Chile
… climate fluctuations. Evidence for pronounced Neoglacial conditions, as reported from some glaciers in the Andes (40° to 50°S) and the South Atlantic between 5000 and <1000 cal. years B.P. have not been found in the sediment records of the Andean transect. However, in the superhumid high …

INVESTIGATION OF DEAD OCEAN QUAHOGS (ARCTICA ISLANDICA) SHELLS ON THE MID-ATLANTIC BIGHT CONTINENTAL SHELF
<p>Ocean quahogs, <em>Arctica islandica</em>, are a long-lived, widely dispersed, biomass dominate in the Mid-Atlantic; therefore, quahog shells are valuable resources for studying climate change over time. Recently, dead ocean quahog shells were discovered south and inshore of the present …
