Sediment from Lakes

Polycyclic aromatic hydrocarbons (PAHs), 47 elements including numerous metals, and visible reflectance spectroscopy or VRS-chla have been determined in sediment core samples collected in 2012, 2013 and 2014 from 16 small (surface area 4-97 ha; maximum depth ~1-5 m deep), hydrologically simple lakes located 30 to 120 km from major oil sands development areas. Canadian Council of Ministers of the Environment (CCME) guidelines are available for 13 of the 53 PAHs reported here. Sediment concentrations did not exceed Canadian Council of Ministers of the Environment (CCME) probable effects levels (PELs), which define the level above which biological adverse effects are expected to occur, for PAHs in any lake. Exceedances of the CCME interim sediment quality guidelines (ISQG) for the protection of aquatic life occurred for 4 PAHs (naphthalene, 2-methyl naphthalene phenanthrene, and benzo(a)pyrene) in 8 lakes.

Ten NETCARE scientists were on board the Canadian Coast Guard Ship Amundsen, a research icebreaker, studying atmospheric and oceanic composition throughout the central Arctic in 2014. The cruise departed from Quebec City on July 8, entered Lancaster Sound on July 17, underwent a partial exchange of scientists at Resolute Bay, Nunavut on July 24, and then headed west through the Northwest Passage. All NETCARE scientists left the ship on August 14 in Kugluktuk, Northwest Territories. The research goal was to assess the impact of the ocean in promoting the formation of atmospheric aerosols.

The Respiratory Virus Detection Surveillance System collects data from select laboratories across Canada on the number of tests performed and the number of tests positive for influenza and other respiratory viruses. Data are reported on a weekly basis year-round to the Centre for Immunization and Respiratory Infectious Diseases (CIRID), Public Health Agency of Canada. These data are also summarized in the weekly FluWatch report.

Mountain goats are a key species in the alpine tundra in Kluane National Park and Reserve. The potential impacts of climate change on snow depth, the frequency of rain-on-snow-events and the position of altitudinal treeline may influence goat foraging, predator dynamics and thus the survival rates of goats. Aerial survey counts of total goats (all adults and young of year) within a defined survey area on Goatherd Mountain have occurred approximately every two years since 1977. Surveys are performed in mid to late-July from a helicopter.

A digital grid of the top of the Empress Fm. Unit 3 sand and gravel, (the uppermost unit in the Empress Formation), where present, or the topography of the surrounding landscape, where Unit 3 is absent. The unit is originally modeled from borehole data and adjusted to the bedrock surface, the surfaces of units 1 and 2 of the Empress Formation, the and present-day land surface. The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.
