Sheila Hynes, Steve Solomon & Dustin Whalen
Field work and airphoto studies were undertaken between 1953-1996 along the Yukon coast of the Beaufort Sea in Ivvavik National Park to determine coastal erosion rates, processes and hazards in relation to archeological and cultural heritage sites, many of which are concentrated along the coast in this region. The work was carried out on behalf of Parks Canada (Canadian Heritage, Western Arctic District, Inuvik) at Niakolik Point, Stokes Point, Catton Point/Ptarmigan Bay, Nunaluk Spit and...

RADARSAT derived monthly ice motion estimates for the Beaufort Sea, 1997-2014

Chris Derksen, Stephen Howell & Mike Brady
Ice motion estimates were derived from RADARSAT-1 and RADARSAT-2 ScanSAR imagery using the Canadian Ice Service Automated Sea Ice Tracking System (CIS-ASITS). The system applies a combination of cross-correlation and phase-correlation methods of feature tracking to sequential SAR-image pairs. Ice drift vectors of varying confidence levels are produced from examining the image pairs at multiple resolution levels. Estimates were gridded at 200 m pixel resolution and organized by month. Using outputs produced by the CIS-ASITS...

Avian predator monitoring at Fosheim Peninsula, Ellesmere Island

Canadian Wildlife Service Josée Lefebvre
Abundance of avian predator species is determine every two days through visual counts from a vantage point and line transects from our arrival at the study until our departure. We also monitor nests of avian predators found opportunistically in our study area.

Monitoring the relative abundance of bird and mammal species at Fosheim Peninsula, Ellesmere Island

Canadian Wildlife Service Josée Lefebvre
The relative abundance of species is recorded as the number of individuals seen per hour spent in the field per observer. Each observer record daily the animal species encountered in the field and the number of individuals observed. To correct for any potential biases the activities and mode of transportation of observers is also taken into account. We also monitor the nests of bird species that are not part of our long-term monitoring and are...

Long-term monitoring of goose forage plant community standing crop on Akimiski Island, Nunavut

Kenneth F. Abraham
Monitoring of the standing crop or primary production of the main goose forage species has been conducted since 1997. Temporary exclosures are erected seasonally to allow comparison of grazed and ungrazed swards of Puccinelia phyrganodes and Festuca rubra. Samples are collected at 5 sites along the north shore, usually at the beginning, middle and end of the growing season, but in some years every 10 days. Other descriptive or experimental work is conducted in concert...

Long-term monitoring of the cycles and success of breeding activity and habitat of shorebirds on Akimiski Island, Nunavut

Kenneth F. Abraham & Erica Nol
A study of semipalmated plovers was initiated in 2002 and is ongoing. Nesting ecology studies include ground searches for nests and monitoring of nests. We record location, nest timing, nest success, habitat characterization at multiple scales, foraging habitats and food supplies. We also band adults and young and follow histories of return, pair membership, etc. of these birds. All data are spatially referenced. ** Data from the IPY years 2007-2009 are available for download. If...

Monitoring of the terrestrial food web dynamics on Akimiski Island, Nunavut

Kenneth F. Abraham
Following ArcticWOLVES protocol, 1-cm3 tissue samples are dissected from freshly dead animals found opportunistically. One large wing feather, or numerous smaller body feathers are taken from avian prey species, and 1 ml of egg (yolk and albumin mixed) are collected from abandoned nests. From mammalian species, a 2 cm2 section of fur is collected. ** If data are downloaded and used for analyses, it would greatly be appreciated that the principal investigator be informed.

Alexandra Fiord Autostation data

Greg Henry
The year 1998 was the warmest on record in Canada and globally, with particularly pronounced warming anomalies located over the Canadian Arctic in the spring and fall seasons. This warming had major implications for snow, ice and permafrost (the cryosphere) in the North e.g., open water formed earlier than had been previously observed, sea ice extent in the Canadian Arctic in September was 25% less than the previous recorded minimum, and there was above normal...

Water column physico-chemical profiles of lakes and fiords along the northern coastline of Ellesmere Island (Ward Hunt Island observatory)

Warwick Vincent, Denis Sarrazin, Andrew Hamilton, Derek Mueller, Dermot Antoniades, Julie Veillette, Luke Copland, Marie Lionard, Sophie Charvet & Sébastien Bourget
This dataset includes physico-chemical profiling records from lakes and fiords along the northern coastline of Ellesmere Island. Measured parameters (conductivity, temperature, salinity, total dissolved solids, pH, oxidation reduction potential, turbidity, dissolved oxygen) varied according to the instruments used (mainly RBR XR-420-CTD, RBR XR-620-CTD, Hydrolab Surveyor 3 and Hydrolab DS5X). This dataset spans from 1954 until 2012. Data prior to 1999 is from historical reports and published data. The most recent data was collected by the...

Long-term monitoring of breeding activity of Greater Snow Geese on Bylot Island, Nunavut

Gilles Gauthier, Marie-Christine Cadieux &
We are monitoring the nesting activity of Greater Snow Geese. We find nests through systematic searches of both fixed and random plots throughout the goose colony. Nests of other goose species are also monitored opportunistically. All nests found are positioned with a GPS and revisited several times to determine nesting density, laying date, clutch size, hatching date and nesting success. Young are marked with web tags at hatch. During brood-rearing, family size is determined periodically....

Long-term monitoring of the cycles and success of breeding activity of shorebirds on Bylot Island, Nunavut

Joël Bêty &
We are monitoring the nesting activity of shorebirds on the island in 2 areas distant of approximately 30 km. We are conducting regular searches throughout the breeding season using the single observer and rope-drag nest searching technique. Every shorebird nests found are monitored throughout the breeding season but the most abundant species are Baird's and White-rumped sandpipers and American golden plovers. Date of nest initiation is estimated for each nest using the egg flotation technique....

Long-term monitoring of plant net primary production, flowering times and goose grazing impact on vegetation of the Cape Churchill Peninsula, Manitoba

Robert L. Jefferies, Emma Horrigan & Robert F. Rockwell
Measurements were taken of above- and below-ground standing crop in wet sedge meadows and an intertidal salt marsh in grazed and ungrazed plots treated with nutrients (NPC, NP, C, control). Plot sizes were 50 cm x 50 cm (n = 3 or 5). The nutrient content of the plant samples will be analyzed and the results of the dry weight of biomass will be used to estimate net primary production. Plots are harvested in early...

Monitoring of breeding activity of Long-tailed Jaegers at Alert, Nunavut

R.I. Guy Morrison
We are monitoring the nesting activity of Long-tailed Jaegers. We find nests through either systematic searches or opportunistically. All nests found are positioned with a GPS and revisited during the breeding period to determine laying date, clutch size, hatching date and fledging success.
