Long-Term Landscape Evolution of Hall Peninsula, Baffin Island, Nunavut: Insights from Low-Temperature (U-Th)/ He Thermochronology C
Atlantic Geology Volume 49 .. 2013 24 Long-term landscape evolution of Hall Peninsula, Baffin Island, Nunavut: insights from low-temperature (U-Th)/ He thermochronology C. Gabriel Creason and John C. Gosse Department of Earth Sciences, Dalhousie University, Halifax, Nova Scotia B3H 1N5, Canada <[email protected]> The northern coast of Hall Peninsula, Baffin Island, comprises a portion of the eastern Canadian Arctic Rim, an extensive physiographic feature with high relief spanning from southeastern Ellesmere Island to northern Labrador. Much of the high relief (> 1000 m) on Hall Peninsula has been attributed to incision during rift-flank uplift associated with Baffin Island separating from Greenland; however, the mechanisms for maintaining this high relief are poorly understood. In the nearby Torngat Mountains to the south, geophysical and thermochronologic data indicate the presence of a crustal root that induced rapid rift flank uplift. Conversely, thermochronologic data from Cumberland Peninsula to the north does not support the presence of a crustal root, suggesting other mechanisms responsible for the generation of its high relief. In the summer of 2012, 50 low-temperature thermochronology (e.g., apatite and zircon (U-Th)/He) samples were collected along three strategically positioned transects to determine the regional cooling history of the rocks on Hall Peninsula. Spatial distributions of the cooling ages of samples from two horizontal transects, one oriented parallel and one perpendicular to the Baffin rift-margin, will provide insight to the role (if any) of pre-existing drainage systems in the development of the high relief on eastern Hall Peninsula. Data from a vertical transect will be used to determine the rate of exhumation, if it varied with time, and the total amount of rock exhumed. -

Tab 6 Estimating the Abundance Of
SUBMISSION TO THE NUNAVUT WILDLIFE MANAGEMENT BOARD FOR Information: X Decision: Issue: South Baffin Island Caribou Abundance Survey, 2012 and Proposed Management Recommendations Background: Caribou are a critical component of the boreal and arctic ecosystems. They are culturally significant to local communities and provide an important source of food. In some areas, there is still uncertainty on population trends because of the lack of scientific information due to difficult logistics and remoteness. This is particularly true for Baffin Island, where three sub-populations of Barrenground caribou (Rangifer tarandus groenlandicus) are hypothesized, though little is known about their abundance and trends over time (Ferguson and Gauthier 1992). In the past 60 years, only discrete portions of their range have been surveyed and no robust quantitative estimates at the sub-population level were ever derived. For over a decade Inuit from communities on northern Baffin Island, and more recently from across the entire island, have reported declines in caribou numbers, although no quantitative estimates are available. In total 10 communities, representing half of all Nunavummiut, traditionally or currently harvest Baffin Island caribou. At the same time, climate change, including increased arctic temperatures and precipitation, and anthropogenic activities connected to mineral exploration and mining are potentially negatively impacting caribou and their range. Due to the risk of these cumulative negative effects, and the importance of these caribou to communities, the Department of Environment undertook, in 2012, a quantitative caribou abundance aerial survey of South Baffin Island with the support of the NWMB and co- management partners. This area represents the most abundant area of caribou on Baffin Island. -

South Baffin Caribou Fall Composition And
Project #: 2-16-14 South Baffin Caribou Fall Composition/Demographic Surveys Interim Report to the Nunavut Wildlife Management Board February, 2017 Prepared by: Mitch W Campbell1 1 Nunavut Department of Environment, Arviat, Nunavut. Department of Environment 1 Campbell, M.W. Introduction/Summary: Based on an extensive survey of the entire Baffin Island complex in 2014 the Department of Environment estimated there were between 159 and 622 tundra wintering Barren-Ground caribou in North Baffin and between 1,777 and 4,207 in South and Central Baffin (As defined by 2014 survey- not suggesting population boundaries). Inuit Qaujimajatuqangit suggests there are currently less caribou on Baffin Island than there has been in more than 50 years. Caribou are culturally significant to Inuit and provide an important source of food and thus their persistence and recovery is vital to traditional life and food security on Baffin Island. We sought to determine ongoing fall calf recruitment as an indication of whether the caribou population is productive or unproductive. Initial findings in fall 2015 suggested high productivity with calf/100 cow ratios reaching 77 in south Baffin and 71 in central Baffin. Spring 2016 composition studies found that many calves did not make it through the 2015/16 winter season showing a drop to 22 calves/100 cows in the south Baffin and a drop to 27 calves/100 cows in the central Baffin. South Baffin calf:cow ratios between fall (October) 2015 and Oct 2016 dropped from 77 calves/100 cows to 41 calves/100 cows suggesting an overall drop in productivity over the period. -

JACOBS SATELLITE IMAGE ATLAS OF GLACIERS OF THE WORLD Edited by RICHARD S. WILLIAMS, Jr., and JANE G. FERRIGNO U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 1386–J–1 The glaciers on Baffin Island are primarily ice caps or ice fields and associated valley outlet glaciers and include numerous small glaciers as well. The two largest ice caps, the Barnes Ice Cap (5,935 km2) and the Penny Ice Cap (5,960 km2) are thought to be the last remnants of the Laurentide Ice Sheet. Approximately 8 percent of Baffin Island is covered by glaciers (36,839 km2). Nearby Bylot Island is heavily glacierized; it has 4,859 km2 of its area covered by glaciers, about 45 percent of the island.

Abstract This study is part of the Canada-Nunavut Geoscience Office’s Hall Peninsula Integrated Geoscience Program, a multiyear bedrock and surficial geology mapping program with associated thematic studies. Baffin Island is characterized by fault- line bounded physiographic provinces that reflect lithological and structural elements inherited over the past two billion years. The northern coast of the Hall Peninsula half-horst is a rugged highland that constitutes a portion of the eastern Arctic Rim, a mountain range extending from northern Labrador to southern Ellesmere Island. Although Quaternary ice sheet and alpine glacial erosion has increased the relief of the mountain range, it appears from thermochronology and marine stratig- raphy that much of the relief was generated by incision through isostatically and thermally uplifted lithosphere accompany- ing rifting from Greenland. In the past decade, offshore geophysical surveys have provided a firmer understanding of post- rift processes and the nature of the continental-ocean crust boundary in Baffin Bay and Davis Strait. -

FEA TURE and Photography Part Two: Through the Looking-Glass: The Photographs of Robert J. Flaherty and Peter Pitseolak BY AMY ADAMS' n August 14, 1913, a young prospector named Robert Flaherty sailed out Oof St. John's harbour in Newfoundlandaboard the steam schooner Laddie, northward bound forthe Hudson Strait, Baffin Island and the Belcher Islands. His mission was to explore these regions in search of iron ore deposits; it was his third prospecting and exploration journey to the Canadian North. Upon reaching Hudson Strait, with winter freeze-up threatening, Flaherty and his crew sought shelter at Amadjuak Bay on southern Baffin Island, establishing a winter camp there with the help of local Inuit. During the 10 months of winter that followed, many Inuit from the camps in the surrounding area came to visit and trade with them. Flaherty also made several trips inland and onto the Foxe Peninsula, surveying the land and prospecting for ore, travelling and living with his Inuit crew members and the families they came across (Griffith 1953; Calder-Marshall 1963; Flaherty 1924). Among the many Inuit Flaherty met that winter was a boy of about 11 named Peter Pitseolak. Their meeting might have been unremarkable had it not been for the seemingly innocuous fact that Flaherty had brought a camera with him. Flaherty had long been fascinated with the Inuit and their way of life, photographing the land and people on his early journeys purelyout of personal interest. He eventually began bringing a movie camera as well as his usual still camera, his effortsculminating in the well-known film Nanook of the Narth ( 1924). -

Department of Earth Sciences, Dalhousie University, Halifax, NS, B3H 3J5 Canada The Foxe Peninsula lies north of the former Hudson Strait ice stream and along the southern margin of the Foxe Dome of the Laurentide Ice Sheet, placing the peninsula in a salient loca- tion to record glaciologically significant events such as marine incursion in Hudson Strait and Foxe Basin. Field data collected in 2006, as part of the Southwest Baffin Integrated Geoscience Project (SWBIG), have led to an improved model of ice flow and deglaciation in the area, based on ice-flow indicators, ma- rine-limit features, distribution of erratics, till geochemistry and radiocarbon dating. At full glacial conditions, ice flowed toward the east in Hudson Strait.

The western sector experienced more changes in ice flow, where the potentially full ice configuration flow was toward the southeast, possibly from the Foxe Divide, radiating from the Foxe Dome. Later, flow in the western sector shifted southward, as an apparently greater control was exerted from the Amadjuak Divide.
