The "Canadian Database of Geochemical Surveys" has two long-term goals. Firstly, it aims to catalogue all of the regional geochemical surveys that have been carried out across Canada, beginning in the 1950s. Secondly, it aims to make the raw data from those surveys available in a standardised format. Over 1,500 surveys have been catalogued. Of these, the raw data for over 300 have been converted to a standardised format. The catalogue can be searched at https:\\geochem.nrcan.gc.ca

The bank of oblique photographs of Northern Quebec is composed of georeferenced photos taken on board planes or helicopters during flights carried out as part of the program for the acquisition of ecological knowledge in Northern Quebec as part of the economic, social and environmental development project “Plan Nord”. During these overflights, the personnel on board were equipped with high-resolution cameras connected to a satellite geolocation system (GPS). The photos obtained in this way served as control points to improve the various thematic maps. __Note:__ For the purposes of distributing this bank, the photos could be modified slightly in order to improve the shooting. Georeferencing photos on the map refers to the location of the plane or helicopter at the time the shot was taken. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

PURPOSE:Given the paucity of information on Arctic char along western Hudson Bay, in 2018, Fisheries and Oceans Canada (DFO) hosted an Arctic char workshop in Rankin Inlet, Nunavut, bringing together local resource users, knowledge holders, and co-management groups (e.g., Hunters and Trappers Organizations, Regional Wildlife Organization) to identify and discuss community-based Arctic char research priorities across the Kivalliq region of Nunavut. Communities were especially interested in examining “what Arctic char were eating” and “why the colour of their muscle is different” along the western Hudson Bay coastline, and in the summer of 2018, a regional community-based Arctic char monitoring program was implemented across the region. DESCRIPTION:Climate-induced alterations to Arctic sea ice dynamics are influencing the availability and distribution of resources, and in turn, the nutrient and energy intake of opportunistic predators across the food web. These temporal changes in local prey communities likely influence the availability of carotenoid-rich prey types, as well as the foraging ecology of opportunistic predators that forage in the marine environment, such as anadromous Arctic char (Salvelinus alpinus). Despite its socioeconomic importance across its range, anadromous Arctic char foraging ecology and its influence on muscle pigmentation, particularly in relation to sea ice dynamics, remains understudied. Here, over two years (2021, 2022) with contrasting sea ice dynamics, we investigated the foraging ecology of anadromous Arctic char and its influence on their muscle pigmentation at a southern (Rankin Inlet) and northern (Naujaat) location along western Hudson Bay using a combination of stomach contents, stable isotopes (δ¹³C and δ¹⁵N), highly branched isoprenoids, carotenoid spectrophotometry, and a standard muscle colour scale (DSM SalmoFan). Spatiotemporal variation in Arctic char diet occurred, where Rankin Inlet Arctic char generally consumed more fish and phytoplankton-based carbon sources, occupied a higher trophic position, and displayed a similar isotopic niche breadth compared to Arctic char in Naujaat. Invertebrates were higher in carotenoid concentration than fishes, and in association with a more invertebrate-based diet, Arctic char in Naujaat contained higher muscle carotenoid concentrations (e.g., astaxanthin) compared to Rankin Inlet Arctic char in 2021. In 2022, however, muscle carotenoid concentrations in Naujaat and Rankin Inlet Arctic char were more similar, as the diet of Arctic char in both locations was largely fish-based despite muscle colour remaining redder in Naujaat Arctic char. Overall, the observed plastic foraging ecology of Arctic char highlights this species' ability to adjust to inter-annual variability in environmental changes, which then impacts their muscle carotenoid concentration. Such inter-annual variation in Arctic char foraging ecology is anticipated to increase with unpredictable climate-driven environmental changes in the region, which could therefore negatively affect local resource users over the long term, resulting in socioeconomic impacts across the Arctic.Collection/sampling methodology:Arctic char were collected by angling and gillnetting (5.5” mesh, regularly checked) between June and August in the estuarine and marine environments near the communities of Rankin Inlet and Naujaat, Nunavut. In 2021, Naujaat Arctic char were collected by community fishers as part of a community-based sampling program. Concurrently, invertebrate prey types were opportunistically collected in the vicinity of Arctic char sampling sites using a conical zooplankton net (200-μm mesh; 10-minute tows) or obtained fresh from Arctic char stomachs. Additionally, marine fishes were opportunistically collected by angling or obtained fresh from Arctic char stomachs over both years in Rankin Inlet, while samples from the Naujaat area were collected in 2018 and 2019.The Kivalliq Wildlife Board (Rankin Inlet, NU) and Arviq Hunters and Trappers Association (Naujaat, NU) each supported this community-formulated research project and assisted with sample collections throughout the duration of the project.

11 tagged Blue whales (Balaenoptera musculus) were tracked during the daytime movements as well as the feeding behaviour in the St. Lawrence River estuary. Kernel density was applied to derminate the high density feeding areas of all individuals combined (30, 40, 50, 60, 75, 95 %).Doniol-Valcroze T, Lesage V, Giard J, Michaud R, 2012.

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 Nahidik program provided data to provide a baseline for future studies as well as an information source for environmental assessment.

The food desert is a sector offering poor access to food stores (grocery stores, supermarkets and public markets), i.e. a distribution area (AD) in which residences are located on average more than 1 kilometer from a food store in urban areas and more than 16 kilometers in rural areas, and characterized by very high material deprivation (quintile 5). Accessibility to food stores is a quantitative measure used to assess the geographic ease of access with which individuals or populations can access food stores (grocery stores, supermarkets, and public markets) from where they live.For more information on the food desert index, you can consult * [Identifying Food Deserts] (https://www.inspq.qc.ca/boite-a-outils-cooperative-alimentaire/identification-deserts) *.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The term “geotechnical investigation site” refers to locations where geotechnical (surveys and instrumentation) and geophysical data are available. This data includes:Geotechnical investigation sites (site_inv_geotech_p): Geotechnical surveys produced by or for the Ministry from the 1990s, from the active database of the Directorate of Geotechnics and Geology (DGG). Data is added as it is validated.This file is accompanied by a Stratigraphic Characteristics table (site_inv_geotech _STRATI.csv). This contains stratigraphic information for the majority of sites and can be linked to the location file using the “NO_UNIQUE” primary key.BDG geotechnical investigation sites (site_inv_geotech_bdg_p): Geotechnical drilling and drilling from an “inactive” database entrusted to the DGG by the Ministry of Natural Resources and Wildlife (MRNF), since the mid-1980s. These are drilling and survey data compiled by the MRNF in the 70s and 80s for “predictive” or “geotechnical soil suitability” mapping campaigns.As it is an inactive database (not evolving), there are no updates to be expected.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
