    The Stanley Park Winter Waterbird Survey, 1995-2019, was made possible through a co-operative effort between Environment and Climate Change Canada, the British Columbia Institute of Technology’s Wildlife and Recreation Program, and the Stanley Park Ecology Society. The intent of the survey is to collect data to estimate the presence, abundance, and distribution of waterbirds along the Stanley Park foreshore in Vancouver, British Columbia, Canada. This dataset is a compilation of species-level occurrence, abundance and distribution data of marine birds collected systematically for the last 23 years (1995-2019) on roughly a weekly basis between September and April each year along the Stanley Park seawall. This long-term dataset of marine birds, has a high value for analysing spatiotemporal trends in marine bird species.

    As part of a three year study funded by Environment and Climate Change Canada and Natural Resources Canada (ecoENERGY Innovation Initiative, project UOSGQ963; http://www.nrcan.gc.ca/energy/funding/current-fundingprograms/eii/4985) data were gathered to assess and monitor water quality conditions in northeastern British Columbia (BC). Defined in this datasetas portions of the Petitot, Fort Nelson, and Hay River basins, northeast BC is a region subject to both historical conventional oil and gas development and more recent unconventional oil and gas (UOG) development. UOG development in this area is presently focused on the Horn River Basin, Cordova Embayment and Liard Basin shale formations (BCOGC 2010, 2013a). Otherwise, UOG development in BC is centered in the Montney Play, located further south (Adams et al. 2016). Surface water quality assessment and monitoring focused on two river basins in this area: the Petitot River Basin and the Fort Nelson River Basin. Baseline and/or best available surface water quality information was gathered from January 2012 to March 2015. Benthic macroinvertebrates were collected over the same period to complement the water quality study through development of a Canadian Aquatic Biomonitoring Network (CABIN) bioassessment model. Routine Water Quality Monitoring study objectives were to gain a better understanding of water quality conditions in the Petitot River Basin by collecting baseline data using a standard suite of physical-chemical variables and establishing a representative long-term site. Routine water quality sampling sites were selected at locations with known exposure to UOG activity and varying watershed areas; submersible loggers were also installed to collect specific conductance and temperature data. Synoptic Water Quality Monitoring study objectives were to establish patterns of spatial and temporal water chemistry through synoptic water sampling at high and low flow periods and examine potential relationships between UOG activity and surface water quality. Sample sites were selected at microbasin drainage outlets to represent a range of upstream activity and potential contamination. A series of samples were also collected along the mainstem Petitot River at 20-kilometre intervals from the Alberta border to the Highway 77 bridge to capture potential “step-changes” in water chemistry as the river flows through the northeast BC gas production area. Biological Monitoring study objectives were to establish baseline reference conditions based on benthic macroinvertebrate communities and habitat characteristics, and develop a predictive bioassessment model to assess the ecosystem health of streams in the Liard, Fort Nelson, and Petitot River basins exposed to UOG activity. The biological monitoring study design followed CABIN sampling methodology for benthic macroinvertebrate collections in streams and rivers (Environment Canada 2012, http://www.ec.gc.ca/rcba-cabin). Sampling was conducted at 53 reference sites unaffected or minimally influenced by human activity. Thirty five test sites were also selected across a gradient of UOG activity, based on well densities. A preliminary predictive bioassessment model for northeast BC was established and is available through the CABIN website for future assessment of water quality and ecosystem health in the region.

    Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In partnership with the provinces, territories and other agencies, WSC operates over 2500 active hydrometric gauges across the country, maintains an archive of historical information for over 7600 stations and provides access to near real-time (water level and stream flow) provisional data at over 1700 locations in Canada.

    This collection of data summarizes the companies reporting under the Renewable Fuels Regulations. This data set includes total liquid petroleum fuel volumes, renewable fuel volumes, and compliance unit creation. This data set also includes information on compliance by company. The information was provided to Environment and Climate Change Canada under the Canadian Environmental Protection Act, 1999.

    Communities in east Hudson Bay and James Bay are concerned about ecosystem changes observed in recent decades, particularly related to sea-ice conditions, and also about potential impacts of contaminants from long-range atmospheric transport and regional human activities. The Arctic Eider Society’s Community-Driven Research Network (CDRN) was established to measure and better understand large-scale cumulative environmental impacts in east Hudson Bay and James Bay. Building on CDRN collaborations and activities in five communities (Sanikiluaq, Kuujjuaraapik, Inukjuak, Umiujaq, Chisasibi), this Northern Contaminants Program (NCP) community-based project generated new information on metal bioaccumulation that provide a regionally integrated perspective on metal exposure in the marine environment of east Hudson Bay and James Bay.

    The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018. The sites are located in the west coast, prairies, central and southern Ontario and Quebec, eastern Quebec, and Atlantic Canada. Dry deposition fluxes were estimated using the ambient air concentrations and dry deposition velocities of nitrogen and sulfur compounds. Monitored ambient air concentrations are available from CAPMoN’s Air Filter Pack data, and dry deposition velocities were estimated using ECCC’s Global Environmental Multiscale (GEM) model and Moderate Resolution Imaging Spectroradiometer (MODIS) land use data and leaf area index. Monitored wet deposition fluxes were determined using CAPMoN’s Precipitation Chemistry data and precipitation depth. To evaluate whether acidic deposition exceeded critical loads and assess potential ecosystem effects, aquatic and terrestrial critical loads of acidity were estimated using the Steady-State Water Chemistry and Simple Mass Balance models, respectively, and geospatial tools were used to extract the critical loads data surrounding the CAPMoN sites.

    Ambient air is sampled daily, with a nominal 24-hour sampling period, on a Canadian Air and Precipitation Monitoring Network (CAPMoN) sequential sample head located 10 meters above ground. Air is drawn through a three-stage filter pack consisting of 47-millimeter Teflon, nylon and cellulose filters. Particulate Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++ and Mg++ are collected on the Teflon filter, gaseous HNO3 and a small amount of SO2 are collected by the nylon filter, and gaseous SO2 and residual HNO3 are collected by the K2CO3-impregnated cellulose filter. Filter loadings determined by laboratory extraction and analysis are blank corrected and divided by calibrated sample air volume to get atmospheric concentration in micrograms per cubic meter at International Union of Pure and Applied Chemistry (IUPAC) standard temperature and pressure. The sampling and analysis methodology is described in Sirois and Fricke, 1992.
