Correlations of mesospheric winds with subtle motion of the Arctic polar vortex by Y. Bhattacharya, A. J. Gerrard

“…A ground based Michelson Interferometer stationed at Resolute Bay (74°43' N, 94°58' W) in the Canadian High Arctic is used to measure mesopause region neutral winds using the hydroxyl (OH) Meinel-band airglow emission (central altitude of ~85 km). …”

Diet dichotomy between two migrant seabirds breeding near a high Arctic polynya by Isabeau Pratte, Kelly A. Boadway, Shanti E. Davis, Mark Maftei, Mark L. Mallory

“…We used stable isotopes (δ13C and δ15N) to compare the diet of two ground-nesting seabirds, Sabine's gull (Xema sabini) and Arctic tern (Sterna paradisaea), nesting on an island adjacent to a recurring polynya in the Canadian high Arctic in 2008 and 2009. We show that, unlike Arctic terns, the diet of Sabine's gulls appears to include a non-negligible amount of terrestrially derived prey during early incubation, and that overall both species segregate their dietary niche during pre-laying and early incubation.…”

A Hero in the Friendly Arctic: Deconstructing Vilhjalmur Stefansson's Rhetorical Maneuver by Silje Gaupseth

“…The article deals with Arctic explorer and anthropologist Vilhjalmur Stefansson's self-presentation in the expedition account The Friendly Arctic: The Story of Five Years in Polar Regions (1921), which tells the story of his travels and trials in the Canadian High Arctic in the years between 1913-1918. The account has been considered a key text to Stefansson's Arctic career, and provides a textbook example of his characteristic theory of living off the country in the so-called Eskimo way. …”

History of monitoring the endangered Ivory Gull in the Canadian Arctic by Mark L. Mallory, H. Grant Gilchrist

“…The ivory gull (Pagophila eburnea) is a rare seabird found in the Canadian high Arctic. The Seymour Island Migratory Bird Sanctuary has supported the core colony for ivory gull research since the 1970s, but by the 2000s, survey work was extended across the species’ range in Nunavut, prompted by growing Indigenous concerns of population declines, which led to regular monitoring of colonies. …”

Lidar measurements of thin laminations within Arctic clouds by E. M. McCullough, J. R. Drummond, T. J. Duck

“…<p>Very thin ( &lt; 10&thinsp;m) laminations within Arctic clouds have been observed in all seasons using the Canadian Network for the Detection of Atmospheric Change (CANDAC) Rayleigh–Mie–Raman lidar (CRL) at the Polar Environment Atmospheric Research Laboratory (PEARL; located at Eureka, Nunavut, in the Canadian High Arctic). CRL's time (1&thinsp;min) and altitude (7.5&thinsp;m) resolutions from 500&thinsp;m to greater than 12&thinsp;km altitude make these measurements possible. …”

Water sources and composition of dissolved gases and bubbles in a saline high Arctic spring. by Dale T Andersen, Christopher P McKay, Wayne H Pollard, Margarita M Marinova

“…We investigate the water sources for a perennial spring, "Little Black Pond," located at Expedition Fiord, Axel Heiberg Island in the Canadian High Arctic based on dissolved gases. We measured the dissolved O2 in the likely sources Phantom Lake and Astro Lake and the composition of noble gases (3He/4He, 4He, Ne,36Ar, 40Ar, Kr, Xe), N2, O2, CO2, H2S, CH4, and tritium dissolved in the outflow water and bubbles emanating from the spring. …”

Deployment of a Fully-Automated Green Fluorescent Protein Imaging System in a High Arctic Autonomous Greenhouse by Alain Berinstain, Rita Noumeir, Stephen Braham, Thomas Graham, Anna-Lisa Paul, Matthew Bamsey, Talal Abboud, Robert Ferl

“…In 2006 an initial prototype green fluorescent protein imager system was deployed at the Arthur Clarke Mars Greenhouse located in the Canadian High Arctic. This prototype demonstrated the advantageous of this biosensor technology and underscored the challenges in collecting and managing telemetric data from exigent environments. …”

Sympatrically breeding congeneric seabirds (Stercorarius spp.) from Arctic Canada migrate to four oceans by Autumn‐Lynn Harrison, Paul F. Woodard, Mark L. Mallory, Jennie Rausch

“…Here, we report on three related seabird species that migrated across four oceans following sympatric breeding at a central Canadian high Arctic nesting location. Using telemetry, we tracked pomarine jaeger (Stercorarius pomarinus, n = 1) across the Arctic Ocean to the western Pacific Ocean; parasitic jaeger (S. parasiticus, n = 4) to the western Atlantic Ocean, and long‐tailed jaeger (S. longicaudus, n = 2) to the eastern Atlantic Ocean and western Indian Ocean. …”
