A research survey on American lobster (Homarus americanus) has been conducted annually in the Magdalen Islands since 1995 to assess the abundance and structure of lobster populations in this area. Starting in 2007, the main objective was modified to include the diversity and abundance of benthic species associated with lobster habitat. Only benthic species data associated with lobster habitat are presented in this dataset.Surveys were generally conducted during the first two weeks of September from 2007 to 2020 on the entire south side of the Magdalen Islands, from Grosse-Île to Havre-Aubert. The sampling plan consists of 70 trawl tows on 50 fixed stations, between 4 and 35 meters in depth. Some stations had double tows. Specimens were collected using a Nephrops-type door trawl with a total width of 3.04 meters consisting of four Vexar™ lined baskets of 19 millimeter mesh size in order to harvest small individuals. Start and end positions were recorded to calculate the distance traveled at each tow using the geosphere library in R. The year 2011 is not included in the dataset, as biodiversity data were not recorded. Since 2017, the average tow distance has been reduced from 1000 meters to 500 meters. The opening of the trawl is also noted every minute throughout the duration of the tow so that the area sampled can be calculated. The area covered in each tow was the product of the trawl opening and the distance traveled.The two files provided (DarwinCore format) are complementary and are linked by the "eventID" key. The "Event_data" file includes generic activity information, including date and location. The "Occurrence" file includes the taxonomy of the observed species, identified to the species or lowest possible taxonomic level. For abundance and biomass estimates, contact Benoît Bruneau (Benoit.Bruneau@dfo-mpo.gc.ca).For quality controls, all taxonomic names were checked against the World Register of Marine Species (WoRMS) to match recognized standards. The WoRMS match was placed in the "ScientificnameID" field of the occurrence file. Special cases were noted in the "identificationRemarks" field and selected specimens were confirmed with field photos mentioned in "associatedMedia". Data quality checks were performed using the R obistools and WORMS libraries. All sampling locations were spatially validated.

An annual trawl survey is conducted in Southwestern Nova Scotia and the Bay of Fundy to assess the lobster stocks in the area. The survey is conducted with the Northeast Fisheries Science Center Ecosystem Survey Trawl (NEST), a small mesh trawl with a cod end liner, which ensures the capture of various sizes of lobster. The dimensions and location of the trawl are monitored and recorded throughout the tow using an electronic trawl mensuration system. In addition, water temperature and depth are also monitored. The target tow length is 1 kilometer which is tracked using an Olex marine charting system. Vessel crew, DFO science staff and a contracted at sea observer work together to perform required tasks and collect all relevant data. Catch from each tow is separated by species, weighed and counted. Length frequency data is collected on select groundfish and crab species and detailed morphometric data is collected on each lobster.PARAMETERS COLLECTED:Set information and profile - includes set date, time depth and locationCatch summary - weight and number caught of each speciesLength Freqeuncies - completed for up to 100 fish for selected speciesLobster Morphological Data - detailed data collected on each lobsterBottom TemperatureTrawl MetricsNOTES ON QUALITY CONTROL:Data is visually verified and double keypunched.

Ichthyoplankton surveys were conducted in the Strait of Georgia (British Columbia) during 1979-1981 to ascertain the onset of fish spawning, and to explore distributional pattern and estimate total biomass of fish species.Oblique tows were made using 0.25m2 Bongos equipped with 351 micron Nitex nets of modified SCOR design. All sampling gear was black to minimize potential avoidance and resulting catch bias. The tow procedure generally followed that established by CALCOFI.This dataset contains a compilation of corrected catches of juvenile fishes, fish eggs and fish larvae by station.

The lobster recruitment project is run by the Fishermen and Scientist Research Society (FSRS) through DFO funding. Fishermen participating in the lobster recruitment project collect information about lobster in their fishing area by fishing 2-5 scientific project traps (SPTs) (fished in fixed locations) within the regular commercial season. The SPTs used in all fishing areas are smaller than commercial traps and designed to primarily catch juvenile lobsters below the legal-size limit.These traps are additional to the vessel's legal number of commercial traps. The lobster recruitment project has more than 120 fishers participating from all LFAs along the Atlantic coast of Nova Scotia from LFA 27 in Cape Breton to LFA 35 in the Bay of Fundy (excluding LFA 28, who have not participated to-date).The number of fishermen per LFA and number of SPTs per fisherman are decided on by the LFA Advisory Committees. This decision considers how much additional effort they were comfortable having in the LFA (i.e. number of SPTs) and from how many traps each fisher could be reasonably expected to collect data. It is also important to have fishers dispersed enough to maximize study footprint. DFO Science consults on project design. SAMPLING METHODS: The fishers record the number, sex and length of lobsters captured in each SPT, as well as presence of eggs, tags or v-notch. Bottom temperatures are monitored by placing a temperature recorder in one of their SPTs for the entire lobster season.Cite this data as: Tibbets-Scott, S., Zisserson, B.

A building is a structure that has a roof and walls and stands more or less permanently in one place. Small buildings have only their location recorded. A 'building to scale' is a structure that has one dimension larger than 50 metres for the 1: 20,000 scale and larger than 30 metres for the 1: 10,000 scale. Their extents are recorded. This product requires the use of geographic information system (GIS) software.

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)

PURPOSE:The primary objective of this survey is to obtain an index of the abundance and biomass of American lobster (Homarus americanus) in the Northumberland Strait. This research survey also provides fisheries-independent information for all of the species captured by the trawl.DESCRIPTION:Catch weight, length frequencies, and biological information for crustaceans and fish caught during the annual July-August research vessel trawl survey in Northumberland Strait (NAFO Division 4T). Abundance indices and spatial distribution patterns of commercial and non-commercial crustaceans and other groundfish. PARAMETERS COLLECTED:The full catch is sorted to species, or lowest taxonomic group possible, and weighed. For lobster, carapace length, sex and carapace condition (i.e. stage of moult) are recorded. For female lobster, the presence or absence of eggs is noted and, starting in 2010, the stage of development of the eggs (i.e. new or old) when present was also recorded. Similarly, for crabs, the carapace width, sex and carapace condition (i.e. stage of moult) is recorded as is the presence or absence of eggs (for females). Fish sampling varied over the years but, starting in 2005, length has been recorded for all fish captured.For large catches, the complete catch is sorted and weighed, but sub-sampling, by species, is used for the other measurements.NOTES ON QUALITY CONTROL:Data are checked for irregularities.SAMPLING METHODS:The Northumberland Strait multi-species survey began in 2001 using a stratified random sampling plan. A random selection of sampling sites within the study area is now used. Sampling is completed annually over a 4-week period in July and August. One hundred ten (110) stations are sampled in Northumberland Strait in water depths greater than 4 m at the lowest normal tide. The survey has employed a 286 Rockhopper trawl for all years from 2001 to 2018, except in 2010 and 2011, when a Nephrops trawl was used. In 2019, a new trawl (called the Northumberland trawl) was used in addition to the Rockhopper trawl. The Northumberland trawl is similar to the 286 Rockhopper trawl, but with a smaller footgear and smaller mesh sizes. At each station, the trawl is towed for a set period of time (recently 15 minutes with the rockhopper trawl and 10 minutes with the Northumberland trawl).USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

A research survey on American lobster (Homarus americanus) and rock crab (Cancer irroratus) has been carried out annually on the Magdalen Islands since 1995 to assess the abundance and structure of populations in this area. The survey is carried out during the first two weeks of September and covers the southern part of the Magdalen Islands, from "Baie de Plaisance" to "Grande-Entrée", extending slightly eastwards between "Havre-aux-Maisons" and "Grande-Entrée". The survey lasts 8 to 15 days, depending of the weather conditions, and covers a maximum of 48 stations. Approximately half of the stations are surveyed in duplicate (two tows per station). The tows always cover 500 meters, with a slightly variable trawl opening (as explained above), averaging around 10 meters.The gear used is a Nephrops trawl, a benthic trawl originally developed for langoustine fishing in Brittany, but slightly modified to target lobster. The trawl is deployed from the CCGS Leim and the harvested organisms are hauled aboard and sorted. Cephalothorax length, sex and shell stage are recorded for all lobsters. This is supplemented by information on reproductive conditions for certain size classes, and dissections of 25 males and 25 females per mission. Rock crabs are also included in the survey and are counted with additional measurements of shell width, sex and shell condition that are recorded on predetermined stations. For other stations individuals data are collected depending on the time available between trawl hauls.The publication contains 4 files; the "Information_stations" file which contains the data of the stations, the "Data_homard_lobster_survey" file which contains the measurements of each lobster, the "Nombre_crabe_crab_number" file which contains the count of rock crabs, the "Mesure_crabe_crab_measurement" file contains the characteristics measured for each crab. Each of the files can be linked by the "date", "st", "tr" columns. The “bat” column notes the boat code, because the gear is not deployed in the same way on each boat.*This record consist of raw data and quality has not been verifiedAssociated species are identified and semi-quantitatively counted directly on the sorting table, and the results are presented in the following publication: https://open.canada.ca/data/en/dataset/99cb7034-f3d5-4da4-a5bc-e81315cfb8eb

In 2018, Fisheries and Oceans Canada initiated the Multidisciplinary Arctic Program (MAP) – Last Ice, the first ecosystem study of the poorly characterized region of Tuvaijuittuq, where multiyear ice still resides in the Arctic Ocean. The program MAP-Last Ice takes a coordinated approach to integrate the physical, biochemical, and ecological components of the sea ice-ocean connected ecosystem and its response to climate and ocean forcings. This program provides baseline ecological knowledge for Tuvaijuittuq and, in particular, for its unique multiyear ice ecosystem. The database provides baseline data on fatty acid composition and stable isotopes signatures of sea ice communities in multi- and first-year ice in Tuvaijuittuq. The data were collected during the 2018 spring field campaign of the MAP-Last Ice Program, offshore of Canadian Forces Station (CFS) Alert, in the Lincoln Sea.

This report outlines the results of a project that created a series of maps tracking inshore historical Lobster fishing district boundaries from 1899 to present. This work has been part of Fisheries and Oceans Canada’s (DFO) Blue Economy Lobster Team (BELT) pilot project on the Lobster fishery. To provide the context for the use of historical information within fisheries research, this report provides a brief summation of the discipline of history, its purpose, and its methods. It also describes the different ways that historical data has been used to support the analysis of fisheries, and some of the ways that historians have integrated the techniques of natural and social sciences into their own work. It provides an overview of how the BELT has incorporated historical methods and methodologies into the team’s overall work. The report presents two sets of maps that outline geographical changes in Lobster fishing districts (called Lobster Fishing Areas after 1985) as well as changes in minimum legal size (MLS) and season length information. These maps help to inform a larger understanding of the historical Lobster fishery in the present-day Maritimes Region, and highlight several themes within the fishery. This includes the increasingly intensive regulation of the fishery over time, the inshore nature of the Lobster fishery for the majority of the twentieth century, the variability in the boundaries of Lobster districts over time, and the broad transition from a cannery-based market to a live Lobster market. The maps taken as a whole help to demonstrate consistency of the regulatory approach to Lobster over the twentieth century. However, there are limitations to the interpretive capacity of these maps, as more work should be done to investigate the specific reasoning behind why each change occurred.**Note: The outer boundaries depicted from 1899-1974 are not meant to represent areas where DFO or its predecessor departments had complete or authoritative control of the inshore fishery. In past regulations, districts were described as “on and along the coast.” The outer boundaries assigned to maps prior to 1985 were chosen to make the maps easy to understand relative to current lobster fishing areas.
