The samples from Ellesmere Island in Quttinirpaaq National Park, Canadian High Arctic, were taken between 8 and 15 July 2007 from the following sites: Ward Hunt Lake (83.053N,...

At two different thermokarst sites (a drained thaw pond and a thermokarst basin), permafrost dynamics were characterized using probing and high-frequency Ground Penetrating...

A field-widened Michelson interferometer, ERWIN II, is used to measure Doppler shifts and irradiance in airglow emissions during the polar night. Shifts in the phase of...

The CANDAC Raman lidar (CRL) transmits laser pulses at two wavelengths (532 and 355 nm) and records signal profiles as a function of altitude at 355 (elastic), 387 nm (N2...

The CANDAC 35 GHz vertically pointing Doppler radar (MMCR) was commissioned in September, 2007, as a replaced for a comparable NOAA system that had been operating at Eureka...

The instrumentation was installed in June 1988 and was initially maintained by the Arctic Adaptation Division Canadian Climate Centre, Atmospheric Environment Service (CCC/AES)...

The Cape Bounty Arctic Watershed Observatory (CBAWO) utilizes two adjacent, geologically similar watersheds, West and East, which are currently undergoing climate-driven...

We set out to examine possible links between climate warming and increases in mercury concentrations ([Hg]) in landlocked Arctic char (Salvelinus alpinus) in the High Arctic....

Protist samples were taken using a 6.2 L Kemmerer sampler, transferred to acid-washed, opaque 20 L plastic containers and stored in the dark at 4°C until processing. They were...

Water samples for HPLC analyses were taken late May 2005 and late May-early June 2006 with a 6.2 L Kemmerer sampler at 2 m intervals up to 10 m depth, and at 2.5 m intervals to...

The instrument is a Lidar established by Environment Canada in 1992, which has been used to monitor the ozone and temperature profile of the stratosphere over Eureka, Nunavut....

Soil gas probes were used to collect profile data on soil atmosphere greenhouse gas concentrations. Six different vegetation communities at the Alexandra Fjord lowlands and...

The Cloud Physics and Severe Weather Research Section (ARMP) of Environment Canada (EC) deployed three instruments (termed the Precipitation Sensor Suite) to the Zero Altitude...

We monitored shorebird nests found incidentally and we recorded and measured any sightings of chicks to give an indication of timing of breeding.

We are monitoring the nesting activity of Greater Snow Geese and Eastern High Arctic Brant (2007-2008 only). All nests found are positioned with a GPS and most of them were...

During the 2013 field season, we collected data on phenological timing of both flowering and leaf growth across a thermokarst area measuring 0.03 km2 with the adjacent polar...

Air and soil temperatures, relative humidity, wind speed and direction were recorded at an automatic climate station. Measurements were taken every minute by a Campbell...

Thicknesses of the Milne, Petersen and Serson Ice Shelves were measured with a PulseEkko 100 GPR system in early April 2008. These measurements were made from a komatiq sled...

Year-round (365/24) operation of the PEARL complex has been achieved with more than 25 operating instruments and associated data downloads and archiving. A particular strength...

We flew a survey of central Ellesmere Island (Fosheim Peninsula, Raanes Peninsula, and Svendsen Peninsula), Nunavut, between March 8-20, 2017 to update the population estimate...
