  journal={Geophysical Research Letters},
[1] Field observations and RADARSAT imagery of the Ward Hunt Ice Shelf (lat. 83°N, long. 74°W), Nunavut, Canada, show that it broke in two over the period 2000 to 2002, with additional fissuring and further ice island calving. The fracturing caused the drainage of an ice-dammed epishelf lake (Disraeli Fiord), a rare ecosystem type. Reductions in the freshwater volume of Disraeli Fiord occurred from 1967 to the present and accompanied a significant rise in mean annual air temperature over the… Expand

Ice shelf break-up and ecosystem loss in the Canadian High Arctic
Over the last 3 years, extensive fractures have appeared in the ∼3000-yr-old Ward Hunt Ice Shelf (83°N,75°W).The largest fracture, a north-south-oriented serpentine feature (Figure l), now forms anExpand
Holocene dynamics of the Arctic's largest ice shelf
Sedimentary data indicate that the Ward Hunt Ice Shelf remained stable for almost three millennia before a major fracturing event that occurred ∼1,400 years ago and freshwater was a constant feature of Disraeli Fiord until the catastrophic drainage of its epishelf lake in the early 21st century.

Dynamic response of an Arctic epishelf lake to seasonal and long-term forcing: implications for ice shelf thickness
Abstract. Changes in the depth of the freshwater–seawater interface in epishelf lakes have been used to infer long-term changes in the minimum thickness of ice shelves; however, little is known aboutExpand
A millennial‐scale record of Arctic Ocean sea ice variability and the demise of the Ellesmere Island ice shelves
[1] Sea-ice ice shelves, at the apex of North America (>80° N), constitute the oldest sea ice in the Northern Hemisphere. We document the establishment and subsequent stability of the Ward Hunt IceExpand
Changes in Canadian Arctic Ice Shelf Extent Since 1906
The ice shelves along the northern coast of Ellesmere Island have been in a state of decline since at least the early twentieth century. Available data derived from explorers’ journals, aerialExpand
Limnology of Two Antarctic Epishelf Lakes and their Potential to Record Periods of Ice Shelf Loss
George VI Ice Shelf is the largest ice shelf on the western side of the Antarctic Peninsula and its northern margin marks the southern most latitudinal limit of recent ice shelf retreat. As part of aExpand
Factors Contributing to Recent Arctic Ice Shelf Losses
A review of historical literature and remote sensing imagery indicates that the ice shelves of northern Ellesmere Island have undergone losses during the 1930s/1940s to 1960s, and particularly sinceExpand
Arctic epishelf lakes as sentinel ecosystems: Past, present and future
[1] Ice shelves are a prominent but diminishing feature of the northern coastline of Ellesmere Island in the Canadian High Arctic (latitude 82–83°N). By blocking embayments and fiords, this thickExpand
The Holocene history of George VI Ice Shelf, Antarctic Peninsula
Meteorological records have shown that the Antarctic Peninsula region has warmed at a rate of 3.7 ± 1.6 С during the last century. One of the most publicised aspects of this warming has been theExpand


Ice-shelf collapse, climate change, and habitat loss in the Canadian high Arctic
Abstract Early explorers in the Canadian high Arctic described a fringe of thick, landfast ice along the 500-km northern coast of Ellesmere Island. This article shows from analyses of historicalExpand
The link between climate warming and break-up of ice shelves in the Antarctic Peninsula
Abstract A review of in situ and remote-sensing data covering the ice shelves of the Antarctic Peninsula provides a series of characteristics closely associated with rapid shelf retreat: deeplyExpand
Recent atmospheric warming and retreat of ice shelves on the Antarctic Peninsula
IN 1978 Mercer1 discussed the probable effects of climate warming on the Antarctic Ice Sheet, predicting that one sign of a warming trend in this region would be the retreat of ice shelves on theExpand

Arctic ice shelves and ice islands: Origin, growth and disintegration, physical characteristics, structural-stratigraphic variability, and dynamics
Ice shelves are thick, floating ice masses most often associated with Antarctica where they are seaward extensions of the grounded Antarctic ice sheet and sources of many icebergs. However, there areExpand
Massive, ancient sea-ice strata and preserved physical-structural characteristics in the Ward Hunt Ice Shelf
Two sea-ice layers, one measured as 9 m thick, the other at least 12 m thick and estimated to be 24.5 m thick, have been located by ice core drilling in the west Ward Hunt Ice Shelf. To examine theExpand
Ice Shelf Microbial Ecosystems in the High Arctic and Implications for Life on Snowball Earth
The Ward Hunt Ice Shelf is the largest remaining section of thick (>10 m) landfast sea ice along the northern coastline of Ellesmere Island, Canada, and is similar in several of its physical, biological and geochemical features to the McMurdoIce Shelf in Antarctica. Expand
