Nutrient concentration at the Atlantic Zone Monitoring Program (AZMP)-Quebec’s stations
Time series of dissolved inorganic nutrients (nitrate, silicate, phosphate) (mmol/m2) at the 3 fixed stations and 46 stations, grouped into transects, of the Atlantic Zonal Monitoring Program (AZMP) under the Quebec region responsibility.The mean integrated nutrient data of 2 strata (0-50 m) et (50-150 m) from the last ten years are displayed as 12 layers, 6 for the June survey (2013-2022, 2020 not sampled) and 6 for the autumn survey (2013-2022). Finally, 2 other layers shows the positions of the fixed stations of the program (Anticosti Gyre, Gaspé Current and Rimouski).Each station is linked with a .png file showing the time series of nutrients and with a .csv file containing all the integrated nutrient data acquired at those stations since the beginning of the program sampling (columns : Station, Latitude, Longitude, Date(UTC), Sounding(m), Depth_min/Profondeur_min(m), Depth_max/Profondeur_max(m), Integrated_Nitrate/Nitrate_intégré(mmol/m²), Integrated_Phosphate/Phosphate_intégré(mmol/m²), Integrated_Silicate/Silice_intégrée(mmol/m²)).PurposeThe Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing the Department of Fisheries and Oceans Canada’s (DFO) capacity to detect, track and predict changes in the state and productivity of the marine environment.The AZMP collects data from a network of stations composed of high-frequency monitoring sites and cross-shelf sections in each following DFO region: Québec, Gulf, Maritimes and Newfoundland. The sampling design provides basic information on the natural variability in physical, chemical, and biological properties of the Northwest Atlantic continental shelf. Cross-shelf sections sampling provides detailed geographic information but is limited in a seasonal coverage while critically placed high-frequency monitoring sites complement the geography-based sampling by providing more detailed information on temporal changes in ecosystem properties.In Quebec region, two surveys (46 stations grouped into transects) are conducted every year, one in June and the other in autumn in the Estuary and Gulf of St. Lawrence. Historically, 3 fixed stations were sampled more frequently. One of these is the Rimouski station that still takes part of the program and is sampled about weekly throughout the summer and occasionally in the winter period.Annual reports (physical, biological and a Zonal Scientific Advice) are available from the Canadian Science Advisory Secretariat (CSAS), (http://www.dfo-mpo.gc.ca/csas-sccs/index-eng.htm).Devine, L., Scarratt, M., Plourde, S., Galbraith, P.S., Michaud, S., and Lehoux, C. 2017.

Inventory of macroalgae and benthic macroinvertebrates on the north shore of the Saint-Lawrence Estuary (2019)
This inventory, conducted from September 26th to October 3th, 2019, aimed to describe the community structure of macroalgae and benthic macroinvertebrates of five small estuaries of the Upper North Shore of Quebec, namely Barthélemy Bay and the Colombier, Mistassini, Franquelin and Saint-Nicolas rivers. This inventory is part of a doctoral study of Valentine Loiseau on the global changes in the St. Lawrence system, mainly the study of marine benthic communities in response to changes of salinity, to ensure proper management of the environment in the face of future changes. The main objective is to describe the structure and the levels of specific diversities of mediolittoral communities of benthic macroinvertebrates and macroalgae along a salinity gradient. These five small estuaries were selected because of their similar size, hard substrates and easy access. Three levels of hypoosmotic stress (low, medium, high) and one control level (seawater) were used for each of the selected estuaries, with eight quadrats per stress level. Quadrat positions were randomly selected but had to meet two criteria: (1) regular height in the foreshore to control the influence of other stresses (temperature, exposure); and (2) presence of at least one macroalga to maintain homogeneity. A percentage cover by macroalgal and macroinvertebrate species was estimated, and then all organisms were weighed by species and size group. The salinity of the nearest water point was measured at mid-tide with a portable refractometer and a Castaway-type CTD (Conductivity-Temperature-Density) probe. The inventory was done using a stratified random sampling design and the sampling unit was a quadrat measuring 25 x 25 cm. The three files provided (DarwinCore format) are complementary and are linked by the "eventID" key. The "event_information" file includes the generic information of the quadrat, including date and location. The "additional_information_event_and_occurrence" file includes salinity and substrate type of the quadrat, as well as the total weight of all individuals of the same species caught in the quadrat extrapolated to one square metre of surface. For nudibranchs and barnacles, weight was estimated from the size of the individuals so that they were not removed from the environment. The "taxon_occurrence" file includes the taxonomic inventory of macroalgal and benthic macroinvertebrate species observed in the quadrat, identified to the lowest possible species or taxonomic level and biomass by identified species.For quality control, organisms were identified on the field using the following guide: Chabot, Robert et Anne Rossignol. 2003. Algues et faune du littoral du Saint-Laurent maritime : Guide d'identification. Institut des Sciences de la mer de Rimouski, Rimouski ; Pêches et Océans Canada (Institut Maurice-Lamontagne), Mont-Joli. 113 pages. The taxonomy was checked against the World Register of Marine Species (WoRMS) to match recognized standards and using the R obistools and worrms libraries. The WoRMS match was placed in the "scientificNameID" field of the occurrence file. All sample locations were spatially validated. This project was funded by DFO Coastal Environmental Baseline Program under Canada’s Oceans Protection Plan. This initiative aims to acquire environmental baseline data contributing to the characterization of important coastal areas and to support evidence-based assessments and management decisions for preserving marine ecosystems.
OIC - Quartz Mining Act
Orders in Council (OIC) are regulations or legislative orders in relation to and authorized by an existing Act. This table identifies Yukon lands withdrawn from disposal, usually by Territorial Order in Council. In Corporate Spatial Warehouse (CSW) data is split out into spatial views by Act under which orders are authorized. The tables are comprehensive and include both active and expired orders. Spatial views show only the active data.In this table and spatial views, Regulations by Order in Council (OIC) are spatially represented to provide clarity regarding Yukon lands withdrawn from disposal. Spatial data is viewed by the Act under which the order is authorized. Not all orders are for withdrawal, different levels of withdrawal are common and not detailed in GIS attributes. It is important to read OIC documents for specific details ( [https://legislation.yukon.ca/legislation/page_a.html](https://legislation.yukon.ca:443/legislation/page_a.html) ).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Notice of Work (NoW) Spatial Locations - Public
This point dataset represents both applications for a Mines Act permit and issued authorizations for mining activities proposed in the application. Applications for regional Mines Act permits are known as Notice of Work (NoW) applications. Regional mine permits are issued for mineral and coal exploration activities, sand and gravel production, quarry production, and placer mining. Major mine permits are issued for producing mineral and coal mines. Permits are issued by the chief permitting officer under section 10 of the Mines Act and administered by the ministry. Regional mines include: * Exploration — mineral, coal, rock quarry, industrial mineral or dimension stone * Sand and gravel — aggregate, rock or natural substances used for construction purposes * Placer Most exploration and development activities require a permit under the Mines Act. A decision marks the end of the permitting process for a NoW application. The decision can either be to reject the application or to authorize the mining activities proposed in the NoW. * For new NoW authorizations, a Mines Act permit is issued * For an existing open Mines Act permit, the newly authorized mining activities are amended to the existing permit and the permit is re-issued **NOTE:** Administrative amendments to a NoW are not captured in this dataset. We are currently working to include this addition for a more complete view of the data. For proponents, please log into https://minespace.gov.bc.ca/ to confirm any authorizations on your permits. The ministry is transitioning from point data to polygonal data for permits and authorizations. The polygon dataset is added to when data becomes available. Users should use both the point dataset and the polygon dataset in combination. Polygon representation of permits with authorizations are referred to as Notice of Work (NoW) – Permitted Mine Areas – Regional Mine - Public https://catalogue.data.gov.bc.ca/dataset/c728435d-410e-42f9-81d5-95978c90e44a The downloaded product from the BCGW is a complete set of all the NoW public records. In addition to the records that contain lat/long references to be mapped spatially, this includes records that do not have NoW lat/long or mine lat/long coordinates to spatialize. These records are listed in a CSV file (HSP_NOTICE_OF_WORK_PA_POINT_SV_NullGeom). Notice of Work categories include: Notice of Work application type, Notice of Work application status. **Notice of Work application type** Field: NOW_APPLICATION_TYPE_DESC (NW_APPTYPD) * Coal * Mineral * Placer Operations * Quarry – Construction Aggregate * Quarry – Industrial Mineral * Sand and Gravel **Notice of Work application status** Field: NOW_APPLICATION_STATUS_DESC (NW_APPSTAD) * Approved – mining activities in the NoW application have been authorized * Client Delayed – Client needs to provide additional information or reclamation security * Government Action Required – Government needs to action; this status is triggered once a client has provided the requested information and client delay is no longer valid * Referred – Includes referral to agencies and stakeholders, and consultation with First Nations * Rejected – An application is rejected. Either the application standards are not met or requested documentation or security was not provided * Received – The NoW application has been sent from virtual FrontCounterBC to the ministry database * No Permit Required – Category when an inspector reviews the application and non-mechanized disturbance does not require a permit, for example an IP survey * Referral Complete – Referral and consultation is complete. The government needs to action the next steps * Withdrawn – Client requested the application to be withdrawn * Pending verification – Category for records needing review and verification. Typically, these are historical NoW applications with approvals. Manual review is required * NULL value – missing status and application type **For the public view, please be aware that the ministry:** * Only shows mine commodities of gold or jade/nephrite in the MINE_COMMODITY_DESC (MN_COMD) field. All other commodity values remain NULL (empty)

Assessment Report Geochemistry
The Yukon Geological Survey stores a significant amount of geological information gathered by exploration companies in compliance with the Quartz Mining Act. This information is primarily contained in assessment reports (AR). Since 1920, more than 8000 hardrock assessment reports have been collected, with more than 6000 of these containing geochemical data on surficial samples (e.g., soil, rock, stream sediment, and vegetation). The sheer volume and historical depth of these data provide valuable insight into the mineral potential of the Yukon. Exploration companies rely on data from ARs to search for exploration targets. To aid exploration companies, YGS has developed this database to consolidate geochemical data extracted from assessment reports. This database, the Geochemical Assessment Report Data Extracted database (GARDEd), was created by extracting and compiling data from more than 300 assessment reports. GARDEd was initially populated with data from samples within a 75 km radius of the Casino deposit to evaluate the data extraction procedures and assess the feasibility of the database. Data capture focused on recent ARs because these were available in digital format. The initial release of this database contains approximately 10% of the geochemical data from surface samples within Yukon ARs.YGS encourages users to send feedback to [geology@yukon.ca](mailto:geology@yukon.ca) to assess the usefulness of the dataset and determine how much effort should be invested to capture older, non-digital ARs.Distributed from [GeoYukon](https://mapservices.gov.yk.ca/GeoYukon/) by the [Government of Yukon](https://yukon.ca/) .
