Found 10 records similar to Northern marine coastal and ecosystem studies in the Canadian Beaufort Sea—water quality data

Federal

The objective of this project was to gather data to develop a model of the food web of the lower trophic levels of the nearshore area of the Beaufort Sea. Sampling took place from 2005 to 2008 using the CCGS Nahidik. The multidisciplinary character of the Nahidik program produced measurements of biology/ecology (primary production, phytoplankton, zooplankton, benthos, fish), chemical and physical oceanography, contaminants, geology and hydro acoustics. The data were collected in July and August of each year.

The park monitors water quality of streams and ponds (lakes) on a triennial cycle, reporting on total organic carbon, acidity, phosphorus, nitrogen, dissolved oxygen, turbidity, and Chlorophyll A. These metrics are compiled into a water quality index (WQI) that summarizes overall water quality.

Between 2017 and 2019, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope in August and early September each year. Sampling was conducted from the F/V Frosti at 144 stations along nine multi-year transects, and 32 non-transect stations. Standardized sampling was conducted at pre-determined depth stations (20-40, 75, 200, 350, 500, 750, and 1000 m) using a variety of sampling equipment including benthic fishing trawls, plankton nets, sediment cores, and CTD and water sample profiles. Presented here is the information on the sampling locations, and the sampling gear deployed at each station.

This dataset includes water chemistry data for the La Salle River near Elie, Manitoba, Canada (Water Survey of Canada Hydrometric Station 05OG008) for the time period of 2009 – 2015. The data was collected for hydrological and water quality modelling as part of Agriculture and Agri-food Canada’s Red-Assiniboine Project. Chemical parameters include total dissolved nitrogen, total nitrogen, total dissolved phosphorus, total phosphorus, and total suspended solids. The frequency of data collected ranges from multiple samples per week during high discharge periods from 2013 to 2015 to weekly or sub-monthly frequency from 2009 to 2012 and during periods of low stream discharge.

Many processes and functions in wetlands are driven by water quality, this measure can therefore determine the composition and health of wetland species. Point Pelee National Park collects several parameters to monitor water quality in the park wetlands such as turbidity, total suspended solids, total phosphorus, total nitrogen, and specific conductivity.

The Lake Simcoe lake monitoring program provides measurements of chemical and physical water quality limits such as total phosphorus, nitrogen, chlorophyll a, pH, alkalinity, conductivity, dissolved organic and inorganic carbon, silica, other ions, water transparency, temperature and dissolved oxygen. Samples are collected biweekly during the spring, summer and fall. *[pH]: potential of hydrogen

This record contains satellite-sensed chlorophyll-a concentration images of the Canadian Beaufort Sea at 1.1 km resolution. The dataset consists of 276 images, aggregated into two-week composites by calculating the mean value at each pixel, comprising years 1998 through 2020. The dataset spans two ocean colour sensors, MODIS-Aqua and SeaWiFS. The Arctic Ocean Empirical algorithm was used to calculate chlorophyll-a concentration, after images were corrected for atmospheric effects using the NIR-SWIR switching algorithm, and Remote Sensing Reflectance (Rrs) were produced.

The concentrations of contaminants in seawater influence what is detected in marine mammals and seabirds and levels and time trends of the contaminants in the ocean has been identified as a knowledge gap by the Northern Contaminants Program (NCP). Samples were analyzed for persistent organic pollutants (POPs) including brominated flame retardants (BFRs), perfluorinated substances and mercury. Repeated sampling at the same location and time of year will help develop temporal trend information for contaminants seawater. Supplemental Information

The Northern Contaminants Program(NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DBA.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples.

This record contains two-weekly minimum sea ice concentration images of the Canadian Beaufort Sea at 1.1 km resolution. The dataset originated from the Canadian Ice Service (CIS) Digital Archive weekly regional charts for the western Arctic (See “additional credit” for a link to these data), created by synthesis of remotely-sensed, ship and airborne observations (Fequet, 2005). These vector ice charts were gridded at 1.1 km resolution and aggregated into two-week composites by calculating the minimum sea-ice concentration at each grid cell over each two-week interval in each year. Week numbers were defined using the ISO 8601 convention, and sea-ice concentration isrepresented in tenths (with 0/10 corresponding to an ice-free pixel, ranging to 10/10 corresponding to 100% pixel coverage with sea-ice).
