Late Wisconsinan glaciation and postglacial relative sea-level change on western Banks Island, Canadian Arctic Archipelago
The study revises the maximum extent of the northwest Laurentide Ice Sheet (LIS) in the western Canadian Arctic Archipelago (CAA) during the last glaciation and documents subsequent ice sheet retreat and glacioisostatic adjustments across western Banks Island. New geomorphological mapping and maximum-limiting radiocarbon ages indicate that the northwest LIS inundated western Banks Island after ~ 31 14 C ka BP and reached a terminal ice margin wes…

Re-evaluating the Relevance of Vegetation Trimlines in the Canadian Arctic as an Indicator of Little Ice Age Paleoenvironments
The origin of trimlines associated with the so-called “lichen-free” areas in the Canadian Arctic has been attributed both to perennial snowfield expansion during the Little Ice Age (LIA) and to seasonally persistent snow cover in more recent times. Because of the disparate hypotheses (ecological versus paleoclimatic) regarding the formation of these trimlines, their use as a paleoclimatic indicator has been abandoned for more than two decades. We…
The Younger Dryas and the Sea of Ancient Ice
We propose that prior to the Younger Dryas period, the Arctic Ocean supported extremely thick multi-year fast ice overlain by superimposed ice and firn. We re-introduce the historical term paleocrystic ice to describe this. The ice was independent of continental (glacier) ice and formed a massive floating body trapped within the almost closed Arctic Basin, when sea-level was lower during the last glacial maximum. As sea-level rose and the Barents…
New evidence from the western Canadian Arctic Archipelago for the resubmergence of Bering Strait
Widespread molluscan samples were collected from raised marine sediments to date the last retreat of the NW Laurentide Ice Sheet from the western Canadian Arctic Archipelago. At the head of Mercy Bay, northern Banks Island, deglacial mud at the modern coast contains Hiatella arctica and Portlandia arctica bivalves, as well as Cyrtodaria kurriana , previously unreported for this area. Multiple H. arctica and C. kurriana valves from this site yield…
Changes in late-Neoglacial climate inferred from former equilibrium-line altitudes in the Queen Elizabeth Islands, Arctic Canada
Regional-scale spatial variation in the change in equilibrium-line altitude (ELA) trend surface in the Queen Elizabeth Islands (QEI), Arctic Canada between the `Little Ice Age' (LIA) and 1960 corresponds to Empirical Orthogonal Functions (EOFs) representing specific patterns of summer climate variability found in the modern record. Extreme warm (1953—1962) and cold (1965—1974) decades in the modern record were used as modern analogues of climatic…
Changes in late-Neoglacial perennial snow/ice extent and equilibrium-line altitudes in the Queen Elizabeth Islands, Arctic Canada
Changes in late Neoglaical climate resulted in extensive modification of Arctic terrestrial ice cover. A substantial reduction in terrestrial ice cover in the Queen Elizabeth Islands (QEI) following the `Little Ice Age' (LIA) (~AD 1250—1900), is indicated by widespread, light-toned patches of poorly vegetated terrain, extending back to the modern ice mass. These patches display abrupt outer margins (trimlines), which record the former position an…
A varve record of increased ‘Little Ice Age’ rainfall associated with volcanic activity, Arctic Archipelago, Canada
Varved sediments from Nicolay Lake, Canadian High Arctic, record major summer rainfall events over the last five centuries. Increased incidences of summer rainfall occurred during the coldest periods of the ‘Little Ice Age’ and were strongly clustered in the years immediately following major volcanic events. Comparison of the summer rainfall and proxy air temperature records thus provides a fuller understanding of the nature and causes of natural…
Late Wisconsinan Glaciation of the Central Sector of the Canadian High Arctic
Geomorphic and chronological evidence from Cornwall Island in the Canadian High Arctic Archipelago provides direct evidence for the age and dynamics of the center and northern flank of the Innuitian Ice Sheet that covered the islands during the Late Wisconsonian glacial maximum. Dispersal of erratics and glacial landforms indicate that ice flowed north across the island and converged with ice flowing northwest from Norwegian Bay. Cornwall Island …
An Urgent Appeal to the Government of Canada to Proclaim our Northern Identity
Looming new developments of unprecedented scale now present for Northerners both significant opportunities and challenges, especially if long-term cultural vitality and a sustainable environment are to be maintained. Northern Canada is also a key archive and bellwether for global climate change, and understandably it has become increasingly the focus of foreign researchers, whose resources vastly exceed those of Canadians. In light of this northe…
Canada's Crisis in Arctic Science
Canada has entered a deep crisis in Arctic science. The lack of a formal Arctic Science and Technology Policy has left our highly fragmented efforts in Arctic research exceedingly vulnerable during times of financial stress and left us effectively without a voice. Logistical support, essential for operating in our vast northern territory, has all but disappeared as a facilitator for both government and university research. Within two years, only …
