Maritimes Region Fisheries Atlas: Catch Weight Landings Mapping (2010–2014)

DFO’s Oceans and Coastal Management Division (OCMD) in the Maritimes Region has updated its fisheries landings maps for 2010–2014. These maps will be used for decision making in coastal and oceans management, including mitigating human use conflicts, informing environmental emergency response operations and protocols, informing Marine Stewardship Council certification processes, planning marine protected area networks, assessing ecological risks, and monitoring compliance and threats in coral and sponge closures and Marine Protected Areas. Fisheries maps were created to identify important fishing areas using aggregate landed weight (kg) per 2 x 2-minute grid cell for selected species/gear types.

This dataset has been filtered to comply with the Government of Canada's privacy policy. Privacy assessments were conducted to identify NAFO unit areas containing data with less than five vessel IDs, license IDs and fisher IDs. If this threshold was not met, catch weight locations were withheld from these unit areas to protect the identity or activity of individual vessels or companies.

Maps were created for the following species/gear types: 

1. Atlantic Halibut
2. Bluefin Tuna
3. Bottom Longline Groundfish
4. Bottom Trawl Groundfish
5. Cod
6. Cod, Haddock, Pollock
7. Cusk

Minimum Two-weekly Sea Ice Concentration in the Canadian Beaufort Sea (1998-2020)

This record contains two-weekly minimum sea ice concentration images of the Canadian Beaufort Sea at 1.1 km resolution. The dataset originated from the Canadian Ice Service (CIS) Digital Archive weekly regional charts for the western Arctic (See “additional credit” for a link to these data), created by synthesis of remotely-sensed, ship and airborne observations (Fequet, 2005). These vector ice charts were gridded at 1.1 km resolution and aggregated into two-week composites by calculating the minimum sea-ice concentration at each grid cell over each two-week interval in each year. Week numbers were defined using the ISO 8601 convention, and sea-ice concentration isrepresented in tenths (with 0/10 corresponding to an ice-free pixel, ranging to 10/10 corresponding to 100% pixel coverage with sea-ice). The result is 12 composite images per year in 1998 through 2020 (23 years), corresponding to https://open.canada.ca/data/en/dataset/ee27e86f-7b18-4e3f-8444-0c5efb6110a4.

Epifauna Diversity on Dockside Surface Perimeters in Burrard Inlet and Fraser River Delta, British Columbia

These data sets provide information pertaining to epifauna and substrate estimates collected at dockside perimeters of floating docks located in Burrard Inlet and Fraser River Delta, British Columbia, between August and November, 2020. Data sets were compiled and formatted by Meagan Mak.

Epifauna diversity was examined along surface perimeters of floating docks in Burrard Inlet and Fraser River Delta in southwestern British Columbia. Diversity estimates were obtained from video surveys collected over three depth-intervals: 1) Splash zone (SZ): depth-interval directly 15-cm above air-water interface; 2) Subsurface zone (SSZ): depth-interval (0-21 cm) below air-water interface; and 3) Deep-water zone (DZ): depth-interval below the SSZ (21-41 cm). Dock substrate consisted of combinations of wood, concrete, tires, plastic-floats, and metal, while epifauna and epiflora included anemones, tunicates, sponge, tube-worms, sea stars, bivalves, crabs, nudibranchs, urchins, barnacles, limpets, chitons, isopods, macroalgae and seagrass. Mussels ranged between 46% and 95% coverage across docks (median: 93%), while frequency of occurrence ranged between 85% and 100% (median: 99%), providing a biological-based substrate for other epifauna. The splash-zone consisted of outcropped mussels, encroached macroalgae from the waterline, and invertebrates above the waterline (limpets, chiton). If present, Ulva spp. typically formed a consistent narrow band (2-3 cm) above the waterline across all docks. Benthic (pipefish, sculpin) and pelagic (perch) fish were associated with epifaunal coverage and pelagic (open-water medium) settings. The Coast Guard Sea Island dock may experience episodic low-salinity intrusions supporting marine organisms at this site (ochre star, sculpin, limpet).

Sea Pen Fields in the Eastern Arctic (Cosmos Trawl Sample)

Polygons denoting concentrations of sea pens, small and large gorgonian corals and sponges on the east coast of Canada have been identified through spatial analysis of research vessel survey by-catch data following an approach used by the Northwest Atlantic Fisheries Organization (NAFO) in the Regulatory Area (NRA) on Flemish Cap and southeast Grand Banks. Kernel density analysis was used to identify high concentrations and the area occupied by successive catch weight thresholds was used to identify aggregations. These analyses were performed for each of the five biogeographic zones of eastern Canada. The largest sea pen fields were found in the Laurentian Channel as it cuts through the Gulf of St. Lawrence, while large gorgonian coral forests were found in the Eastern Arctic and on the northern Labrador continental slope. Large ball-shaped Geodia spp. sponges were located along the continental slopes north of the Grand Banks, while on the Scotian Shelf a unique population of the large barrel-shaped sponge Vazella pourtalesi was identified. The latitude and longitude marking the positions of all tows which form these and other dense aggregations are provided along with the positions of all tows which captured black coral, a non-aggregating taxon which is long-lived and vulnerable to fishing pressures.

These polygons identify sea pen fields from the broader distribution of seapens in the region as sampled by Cosmos trawl gear in the Eastern Arctic biogeographic zone. A 0.1 kg minimum threshold for the sea pen catch was identified as the weight that separated the sea pen field habitat from the broader distribution of sea pens with these research vessel tow data and gear type.

Mapping Inshore Lobster Landings and Fishing Effort on a Maritimes Region Statistical Grid (2012–2014)

Fisheries landings and effort mapping of the inshore lobster fishery on the DFO Maritimes Region statistical grid (2012-2014). This report describes an analysis of Maritimes Region inshore lobster logbook data reported at a grid level, including Bay of Fundy Grey Zone data reported at the coordinate level. Annual and composite (2012–2014) grid maps were produced for landings, number of license-days fished, number of trap hauls, and the same series standardized by grid area, as well as maps of catch weight per number of trap hauls as an index of catch per unit effort (CPUE). Spatial differences in fishing pressure, landings, and CPUE are indicated, and potential mapping applications are outlined. Mapping the distribution and intensity of inshore lobster fishing activity has management applications for spatial planning and related decision support. The lack of region-wide latitude and longitude coordinates for lobster effort and landings limits the utility of commercial logbook data for marine spatial planning purposes.

DFO’s fish health monitoring activities at BC aquaculture sites

For health auditing purposes, a farm is considered active once three pens of fish have been present for 30 days, following entry of the first pen of fish at the farm. Fisheries and Oceans Canada (DFO) applies a computerized selection system to randomly select active salmon farms within the fish health zones of the British Columbia. coast. All farms within a zone are assigned a random number and a computer selection of the farms within that zone is weighted (based on the fish species and the number of “active farms” operating in that zone as a percentage of the total number of active farms in the province). In other words, if a zone contains 30 percent of the farms then 30 percent of the farms selected for audit would be randomly chosen from that area. This ensures equal probability of each farm being selected for sampling. To ensure confidence in the sample results, Fisheries and Oceans Canada endeavours to conduct fish health audits at 30 active farmsites per quarter, or approximately 120 each year.  Farm audits are conducted in conjunction with the farm’s regularly scheduled carcass collection, allowing Fisheries and Oceans Canada staff access to the freshest of the dead fish. This approach of targeted disease sampling on recently dead fish increases the likelihood of DFO veterinarians finding disease, if present, and attributing an accurate “cause-of-death” diagnosis to each carcass gathered.  The summary tables are updated quarterly to reflect Fisheries and Oceans Canada’s fish health monitoring activities. For the purpose of fish health monitoring, a site is considered “active” if the facility holds any salmonid for at least 30 days, and has a minimum of three fully stocked pens during the quarter in which sampling is to occur.

Marine sectors in Canada - Summaries

Activities dependent on the ocean make a substantial contribution to the Canadian economy. Fisheries and naval installations provided the rationale for the first European settlement. Fish processing, shipbuilding and marine transportation followed, providing the basis for economic development and growth on all three of Canada's coasts. These ocean activities defined settlement patterns that continue to this day.

New marine economic activities emerged over the years including tourism, aquaculture, bio-technologies, specialized manufacturing and offshore oil and gas exploration and development. A wide range of service industries support these activities. Together, they create opportunities as well as challenges borne of increased and oftentimes competing uses of ocean space.

The tables presented here provide estimates of the economic contribution of marine sectors in Canada for the years 2014 to 2018. These estimates cover all major private sector activities with a direct dependence on the oceans (extractive and non-extractive uses) as well as activities of public sector organizations with responsibilities for safety, managing ocean activities and research.

Canada’s Energy Future 2026: Energy Supply and Demand Projections to 2050

Canada’s Energy Future 2026: Energy Supply and Demand Projections to 2050 is the latest long-term energy outlook from the Canada Energy Regulator (CER). The Canada’s Energy Future series explores how possible energy futures might unfold for Canadians over the long term, building on decades of economic and energy modelling and analysis. Our scenarios cover all energy commodities and all Canadian provinces and territories. This scenario analysis explores future uncertainties facing the energy system. This report includes four scenarios to explore Canada’s energy outlook. One of these is Current Measures, a traditional baseline scenario. To explore uncertainty in energy and economic drivers, we introduce two new symmetrical scenarios that bracket the Current Measures scenario: the Higher scenario and Lower scenario. These scenarios examine outcomes if key drivers of Canada’s energy system—specifically, Canadian gross domestic product (GDP) growth, liquefied natural gas (LNG) exports, data centre electricity demand, and global oil and natural gas prices—trend higher or lower than in Current Measures. We also updated the Canada Net-zero scenario, first introduced in Canada’s Energy Future 2023. Compared to the first three scenarios, that do not have a pre-determined end point, the Canada Net-zero scenario begins with a predetermined end point of net-zero greenhouse gas (GHG) emissions for Canada by 2050—exploring what a pathway to that end point could look like.

Trends and Extremes - Flood Susceptibility Mapping

This collection of flood susceptibility products captures temporal patterns of historic flood events from 2000 to 2023, derived from flood susceptibility maps. The layers are designed to support decision-making by providing easily interpretable information for planning, screening, and other management purposes.

This collection contains several datasets which explore the suite of rasters from 2000 to 2023:

- Extreme wet and extreme dry years and the associated average flood susceptibility, processed by NHN WU, as found by Generalized Extreme Value (GEV) analysis

- Flood susceptibility envelope, which is derived from the above wet and dry years

- Trend slope, for each pixel the value for each year is extracted and the linear trend is computed, greater than 1000 is increasing flood susceptibility and below  1000 is decreasing flood susceptibility. 

- Trend Class, as identified by wet and dry scores, applied to NHN WU

- Current flood susceptibility, which represents the estimated average value of present-day flood susceptibility

- Current interquartile range, which provides and indication of the temporal variability of a given pixel under the current regime.


This dataset forms part of a broader collection of flood susceptibility datasets, offering related information and analyses. The collection includes an overview page with associated publications, historic susceptibility values, temporal trends, and future projections.
