Scientific Infrastructure

Meteorological Stations

Two weather stations operate with annual, on-site download of data. The main station (MainMet), located between the two watersheds, collects comprehensive temperature, humidity, precipitation, radiation and wind parameters at hourly intervals and the second station (WestMet) located in the headwaters of the West River records air temperature (hourly) and precipitation (event-logging).

Hydrometric Stations

A number of river and stream stations operate seasonally. Stations located on the main rivers include discharge, water temperature, turbidity and electrical conductivity measurements at 10 minute intervals.

Extensive manual samples for water chemistry and sediment load are collected, and regular pump sampling was initiated in 2007. Regular water contaminant and ecological samples are collected at these stations. Stations are manually rated for discharge at regular intervals through the melt season. Additional stream stations are located on tributaries and experimental watersheds. These stations measure discharge, water temperature, turbidity and electrical conductivity.

Soil Temperature and Moisture Stations

Soil pore water pressure is recorded at several locations in support of geotechnical research.  Sensors are located near the base of typical active layer. Numerous soil and permafrost temperature stations are located in smaller watersheds in different vegetation types and permafrost settings.  These stations record soil temperature to 70-90 cm depth (typical active layer depth) and three stations record permafrost temperatures to 7 m depth.

Greenhouse Gas Flux Monitoring

An eddy covariance carbon dioxide flux tower was established in June, 2008 in collaboration with E. Humphreys (Carleton University) and operates seasonally.  Portable chamber measurements of CO2 and gas samples have also been collected in a number of additional fixed locations since 2006.

International Tundra Experiment (ITEX) Site

An International Tundra Experiment (ITEX) site was established in 2008 during the International Polar Year. The experiment utilizes open topped chambers to increase temperature and snow fences to augment snow cover. Vegetation plots have been established in a replicated full factorial experimental design with soil trace gas collar stations and soil moisture and temperature stations.

Lake Monitoring

Limnology stations on both lakes are seasonally instrumented with temperature loggers and moored conductivity-temperature-depth sensors (CTD). Manual sediment traps are located in the water columns and recovered at frequent intervals during the field campaigns. Water samples are collected from the water column at regular intervals along with CTD casts on station. A large number of sediment cores have been collected with emphasis on the locations where limnological measurements have been collected. A comprehensive sidescan sonar and acoustic survey of both lakes was completed in 2015 to enhance limnological and sedimentological research.

Time lapse Cameras

Time lapse cameras were installed in 2012 to capture the timing of ice-on and ice-off on both the West and East Lakes. In 2016, three new time lapse cameras were installed in the mid-catchment of the West River, in the larger Boundary River catchment directly west of camp, and at a retrogressive thaw slump to the north of the East River. These cameras capture images every 15 to 60 minutes.
