Annual Solar Radiation 1971-2000
The data represents the annual solar radiation in Alberta over the 30-year period from 1971 to 2000. A 30-year period is use to describe the present climate since it is enough time to filter out short-term fluctuation by is not dominated by any long-term trend in the climate. Daily total incoming solar radiation is measured in megajoules per square metre (MJ/m2). Southern Alberta receives the greatest amount of annual global solar radiation with the amount gradually decreasing as you move farther north. However, cropping is successful in the northern (Peace River) area of Alberta because the longer summer day length helps compensate for the less intense solar radiation. Cloud cover in the mountains will reduce the amount of solar radiation received there.The amount of solar radiation received at the earth's surface varies with two factors that depend on latitude: the angle of the sun's rays and the hours of daylight. The distance from the equator, and therefore the intensity of the sun's radiation has the greatest effect on climate. Canada's position in the northern portion of the earth's northern hemisphere means that it receives less solar radiation compared to countries near the equator. The northward decrease in solar radiation is also noticeable within Alberta. Temperatures are generally higher in southern Alberta in comparison to northern Alberta because the south receives more solar radiation. This resource was created using ArcGIS.
Scientific Survey of the Northern Contingent Atlantic Mackerel (Scomber scombrus)
Since 1979, Fisheries and Oceans Canada has conducted near-annual mackerel egg surveys in the southern Gulf of St. Lawrence using a standardized methodology. This survey typically takes place over approximately 10 days in June and aims to quantify mackerel eggs, thereby contributing to the stock assessment of the northern contingent. Sampling is conducted at 66 fixed stations arranged in a predefined grid (see included image for station locations and names). Additional stations—following the same sampling methodology—have also been surveyed off of southwestern Newfoundland, eastern Cape Breton and south of Prince Edward Island, as well as in other regions. The mackerel survey is often coordinated with the Atlantic Zone Monitoring Program (AZMP) for the Quebec region, which takes place around the same time using the same research vessel and similar equipment. While these two surveys are distinct, they are coordinated to complement each other.At each station, a tow using 61 cm bongo nets (333 µm mesh size) is towed following a saw-tooth profile through the upper 50 m of the water column. Tows last approximately 10 minutes at a speed of roughly 2.5 knots. These tows target mackerel eggs and larvae but collect other species and plankton stages. The taxonomic identification and classification of the developmental stages of the samples are then carried out in the laboratory. The number of taxon counted varies between survey years, based on new species encountered and identified. Egg development stages (I–V) are recorded only for mackerel.This dataset includes the records of all ichthyoplankton species sampled during the survey. It includes information for each sampling station, including gear specifications, species identifications, and life history stages. Each unique combination of COLLECTOR_STATION_NAME, COLLECTOR_EVENT_ID, START_DATE, START_LAT and START_LON represents a single sampling event, and all rows sharing this combination correspond to individual samples collected during that event.The dataset covers the period from 1983 to 2024 and is updated annually as new data become available.It is important to note that prior to 2023, nearly all species were systematically counted, with only a few exceptions where presence alone was recorded. However, since 2023, data collection has shifted to presence/absence for all species, except capelin larvae, herring larvae, and mackerel eggs and larvae, which continue to be counted.Note – raw data use with caution – please contact the author if you have any questions.The data processing methods used for the stock assessment are described in detail in the following publication:Lehoux, C., Van Beveren, E., and Plourde, S. 2024.

Paleowind directions in northern North America from stabilized sand dunes
Past wind directions are mapped from stabilized sand dunes in Canada and the northern United States. The map shows the near-surface wind directions responsible for transporting sand when the dunes were active. The directions were mapped by interpreting the orientation of parabolic dunes from open-sourced Lidar (light detection and ranging) derived digital terrain models. The map also shows new dune areas that add to the existing knowledge of dune fields in North America. The interpreted wind directions provide insight into the past atmospheric circulation patterns that occurred during the deglaciation of North America and the transition to modern circulation patterns that occur today.

Harbour seal (Phoca vitulina) counts and haulout locations along BC coast
Harbour seals (Phoca vitulina) are found along temperate and Arctic marine coastlines of the Northern Hemisphere. They are found in coastal waters of the northern Atlantic and Pacific Oceans, as well as those of the Baltic and North Seas. In Canada, they may be found off the coastal waters of British Columbia, Nunavut, Manitoba, Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia, and Newfoundland and Labrador.Population trends and abundance of harbour seals in British Columbia are assessed based on aerial surveys conducted during 1966-2019. Based on counts conducted in Index Areas distributed throughout the province, the trend observed in the Strait of Georgia appears to be generally indicative of harbour seal populations throughout British Columbia. Total abundance of harbour seals on the B.C. coast in 2008 was estimated to be on the order of about 105,000 (95% confidence interval of 90,900 to 118,900) seals. Total abundance was re-estimated in 2022 (estimate and CI pending completion of CSAS process). Historic reconstructions indicate the population was depleted by a period of commercial harvesting during 1879-1914, and subsequently maintained below natural levels by predator control programs until the early 1960s. Already depleted, the population could not sustain a second period of intense commercial harvesting during 1962-1968 and was further depleted, but now appears to have fully recovered.

MUNICIPALITY
The purpose is to provide end users with a digital data representing the boundaries of incorporated municipalities in Manitoba. It also enables users of Manitoba spatial data to identify which municipality selected features fall within.This dataset is comprised of boundary geometry for all of the incorporated municipalities and Northern Affairs Communities within the Province of Manitoba. The boundaries in this dataset represent the descriptions set forth in the Municipal Status and Boundaries Regulation (567/88R) and subsequent amendments, and regulations under The Northern Affairs Act. The geospatial referencing of the Municipal Boundaries is based on the best available land parcel data for each municipality and Northern Affairs Community. Where available, cadastral data based on registered survey plans was used. Otherwise, the Manitoba Property Assessment Information dataset produced by Manitoba Municipal Relations was used. The delineation of the boundaries was established according to the regulation establishing or amending the boundary of a municipality or Northern Affairs Community. Dataset content is subject to: Ongoing changes in municipal status and boundary and Northern Affairs Community boundary alterations that are generated through annexations, amalgamations, dissolutions or formations, all of which are approved by regulations made under The Municipal Act (for incorporated municipalities) and The Northern Affairs Act (for Northern Affairs Communities). This dataset content is current to the most recent effective date of any such regulation amendment. Ongoing development and maintenance of the land parcel datasets. Improvements to the cadastral data are used to improve the positional accuracy of the municipal boundary polygons. As of the publication date of this dataset the following known issues remain: For municipal boundaries and Northern Affairs Communities that include water boundaries, such as in the Lake Winnipeg and Lake Manitoba areas the water boundary portion that best reflects the municipal boundary was used. In some instances, road allowances on a municipal boundary are included in both of the adjoining municipalities. Please visit the Manitoba Municipal Relations website for more information www.gov.mb.ca/mr/land_use_dev/index.html. The Manitoba Municipal Boundaries data reflects the status of municipal boundaries and Northern Affairs Communities at the time of export and was uploaded to Manitoba Maps as a feature layer. Fields Included: OBJECTID: Sequential unique whole numbers that are automatically generated MUNI_NO: Manitoba municipality identifier number MUNI_NAME: Legal name of municipality MUNI_TYPE: Type of municipality MUNI_LIST_NAME: Name of municipality suitable for alphabetical list MUNI_LIST_NAME_WITH_TYPE: Name of municipality suitable for alphabetical list including type
