This data set contains concentrations of polyaromatic hydrocarbons in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada.

Our current understanding of the factors that influence where birds nest is incomplete, yet such information is important for accurate demographic assessments. To address questions related to spatial distributions of shorebird nests and to evaluate factors that may affect nest distribution in...

This repository holds underlying data for publications arising from NETCARE activities. Unlike the raw measurements available elsewhere in this archive, these data are specific to a particular publication and may have undergone additional analysis and processing. Data are organized by...

In August 2013, NETCARE scientists conducted a campaign on the west coast of Vancouver Island, British Columbia, Canada. The goal of this campaign was to characterize the nature of ice nuclei in a marine environment. Measurements were conducted on the ambient levels of both deposition and...

This campaign took place in April 2015, with a focus on the characterization of ice clouds and pollutant levels, including black carbon, across the Arctic. The campaign was again a collaboration between NETCARE scientists and The Alfred Wegener Institute (AWI). Along with the POLAR 6, the...

NETCARE scientists were on board the Canadian research icebreaker CCGS Amundsen studying atmospheric and oceanic composition throughout the Canadian Arctic in 2016. NETCARE scientists were aboard the ship from 14 July - 25 August, sailing from Iqaluit to Kugluktuk with a personnel change on 27...

From September 2014 to June 2015 NETCARE scientists conducted an intensive snow sampling campaign at Alert, Nunavut, Canada. Fresh snow samples were collected every few days and analyzed for black carbon, major ions, metals, elemental carbon, and organic carbon. Site Information:...

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...

In 2016 NETCARE scientists conducted two measurement campaigns at the Dr. Neil Trivett Global Atmosphere Watch Observatory (the “Alert Observatory”) on the northeastern tip of Ellesmere Island in the Canadian Arctic (latitude: 82.5163, longitude: -62.3085). The first campaign...

A large-scale aircraft campaign (on the German POLAR6 aircraft) took place in July 2014, based out of Resolute Bay, Nunavut, aimed to assess the different roles that oceanic input and long range transport from lower latitudes play in driving Arctic atmospheric composition. For five days in late...

In this study, the chronic effects of two emerging brominated flame retardants, 1,2-bis(2,4,6-tribromophenoxy)ethane(BTBPE) and 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB) were evaluated in diet exposed juvenile rainbow trout(Oncorhynchus mykiss). FIsh uptake was measured after 28-d of...

In this study, Daphnia magna were exposed over three 21d generations to an environmentally relevant concentration of TBOEP (10 μg/L) and effects were evaluated at the gene transcription, protein, and life-history (i.e., survival, reproduction and growth) levels. Results were published in a...

In this study, Daphnia magna transcriptomic response was measured by microarray to evaluate sublethal effects of TBOEP as part of a multi-level biological approach including specific gene transcription measured by qRT-PCR, enzyme activity, and life-history endpoints (i.e., survival, growth, and...

The transcriptomic response of Daphnia magna exposed to sublethal doses of 1H-benzotriazole (BTR), 5-methyl-1H-benzotriazole, (5MeBTR), and 5-chloro-1H-benzotriazole (5ClBTR) was evaluated using RNA-sequencing and quantitative real-time PCR. Cellular (chitinase activity) and life-history...

The objectives of the present study were to evaluate the chronixc effects of 2 BZT‐UVs alone and in a mixture, 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐bis(1‐methyl‐1‐phenylethyl)phenol (UV‐234) and 2‐(2H‐benzotriazol‐2‐yl)‐4,6‐di‐tert‐pentylphenol (UV‐328), in juvenile rainbow trout (Oncorhynchus mykiss)...

In this study, the chronic effects of 2 BZT-UVs, 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol (UV-234) and 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) were evaluated for each compound alone and in a mixture on the freshwater green algae Chlamydomonas reinhardtii...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Sea ice in Canada indicators provide information on the area of sea in Canada covered by ice during the summer season....

The Precipitation Occurrence Sensor System (POSS) is a small X-band 10.525 GHz continuous-wave bi-static vertically pointing Doppler radar. The system reports precipitation occurrence, type and intensity of precipitation at 1-min temporal resolution. Raw measurements are 960 samples per minute....

The Government of Canada’s Fuel Life Cycle Assessment (LCA) Model is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada.

As part of the sediment stability study in the priority area (Areas of Concern) of St Laurent River near Cornwall, ADCP instruments were deployed during the summer of 2022 to collect the flow data in the river. The data collection program is part of GLAP. The field experiments were carried out...
