Atlantic Salmon Smolt Data from the Margaree River, Nova Scotia
PURPOSE:To estimate the abundance of Atlantic salmon smolts in the Margaree River watershed. DESCRIPTION:A rotary screw trap (RST; also known as a smolt wheel) is used to perform a capture-mark-recapture experiment on the main stem of the Margaree River. Smolts are captured at the wheel, a subset are tagged (max 200 individuals daily) and released upriver. Individuals not tagged are enumerated and released at the wheel. A fraction of tagged individuals are recaptured at the wheel. Trap efficiency and smolt abundance can be calculated from this data. USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
Summer Model Outputs and Observations in Discovery Islands, British Columbia
This dataset contains the modelled and observed data used in the publication "Fjord circulation permits persistent subsurface water mass in a long, deep mid-latitude inlet" by Laura Bianucci et al., DFO Ocean Sciences Division, Pacific Region (published in the journal Ocean Science in 2024). An application of the Finite Volume Community Ocean Model (FVCOM v4.1) was run from May 24 to June 27, 2019 in the Discovery Islands region of British Columbia, Canada. Observed temperature and salinity profiles available in this area during this time period are included in the dataset, along with the modelled values at the same times and locations.
Martimes Summer Research Vessel Survey
“Summer” missions occur in June, July and August and these focus on the Scotian Shelf and Bay of Fundy (i.e. 4VWX 5Yb, expanding recently to include the Laurentian Channel and Georges Bank (5Zc). Collected data includes total catch in numbers and weights by species. Length frequency data is available for most species, as are the age, sex, maturity and weight information for a subset of the individual animals. Other data such as ageing material, genetic material, and stomach contents are often also collected, but are stored elsewhere.“Summer” cruises occur in May, June, July and August and these focus on the Scotian Shelf and Bay of Fundy (i.e. 4VWX).Cite this data as: Clark, D., Emberley, J.

Fixed gear sentinel fisheries program - northern Gulf of St. Lawrence
In place since fall 1994, the sentinel fisheries program is the result of a collaboration between Fisheries and Oceans Canada (DFO) and Quebec and Newfoundland commercial fishermen's associations. Under this program, contracts are awarded by tender to fishermen’s associations to carry out fishing activities according to scientific protocols developed by DFO. The main objective of this survey is to collect data that will be used to calculate abundance indices for the northern Gulf of St. Lawrence Atlantic cod stock.Description of fixed gears surveyThe fixed gear sentinel fisheries of the northern Gulf of St. Lawrence are conducted in the sub-division 3Pn and the divisions 4R, 4S of the Northwest Atlantic Fisheries Organization (NAFO) using fixed gillnets or longlines (other fishing gears were also used at the start of the program). Fishing activities with nets must have a mesh size of 5 ½ inches (140mm) and are limited to a maximum of 6 to 20 nets depending on the region and capture and the target immersion time is between 19 to 24 hours. Longline fishing activities, for its part, must be carried out with traditional J #16 or C #12 hooks. The maximum number of hooks varies from 500 to 1000, depending on the catch, and the target immersion time is 4 to 6 hours. Data are collected by observers at sea or by technicians.DataFor each fishing activity, the total catch is sorted and weighed by species. For each species other than Atlantic cod, the number of individuals caught is noted. Atlantic cod are then measured at the fork (cm). Other biological data such as weight (total, gonad, liver and stomach), age, sex and maturity can then be collected on a subsample of cod.The biological data are divided into 4 files: a “Metadata” file containing set information, a “Catches” file containing catches per set for fish taxa, a “Carbio” file containing biological and morphometric measurements per individual, a “Freql” file containing the length frequency of fish.The data collected as part of this program is available below. It is important to note, however, that 1) only traits deemed successful have been retained; 2) historical data may contain inaccuracies; 3) the most recent survey is not available for validation purposes.
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.
NAFO Subareas, Divisions, and Subdivisions
The Northwest Atlantic Fisheries Organization (NAFO) Secretariat, Fisheries and Oceans Canada (DFO) and the Canadian Hydrographic Service (CHS) have collaborated to update the spatial representation of the NAFO Subareas, Divisions, and Subdivisions as defined in Annex 1 to the Convention on Cooperation in the Northwest Atlantic Fisheries (2020) (https://www.nafo.int/Portals/0/PDFs/key-publications/NAFOConvention.pdf). The NAFO Convention does not indicate which datum should be used for spatial representation. The datum used at the time of development of the NAFO Convention would have been North American Datum 1927 (NAD27). However, all datasets were derived using NAD83.International boundaries have been updated based on accepted coordinates between the USA and Canada (http://www.internationalboundarycommission.org/en/maps-coordinates/coordinates.php), and Canada and Greenland (https://www.treaty-accord.gc.ca/text-texte.aspx?id=105136).This version of the NAFO Divisions is not intended to be used for legal purposes and is being provided for mapping / illustrative purposes only.

Soil Texture
This map illustrates the distribution of soil parent material textures in the agricultural region of Alberta. Soil texture is defined by the relative proportions of the sand, silt and clay particles present. Soil textures are identified by classes using the Soil Texture Triangle illustrated below. The Soil Texture Triangle identifies the textural class of a soil at the intersection of the percent sand (x-axis) and the percent clay (y-axis). The percent silt of the soil is the remainder to add up to 100 percent. This resource was created in 2002 using ArcGIS.
