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),...

The excessive input of nitrogen derived from human land-use activities remains a major cause of the eutrophication of coastal ecosystems around the world. However, little data exist on rates of nutrient pollution or its potential impacts to coastal ecosystems in Atlantic Canada. To fill this...

From August 2nd to September 9th, 2013, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope. Sampling was conducted from the F/V Frosti at 64 stations along ten transects. Standardized sampling was conducted on the...

Likelihood of Presence of Finback Whales in the Bay of Fundy and Port Hawkesbury Area Response Plan. The Coastal Oceanography and Ecosystem Research section (DFO Science) reviewed reported opportunistic whale sightings and local knowledge sources to estimate areas where Finback whales are...

Acoustic telemetry allows detailed observations of the movement behaviour of many species and as tags get smaller, smaller organisms may be tagged. The number of studies using acoustic telemetry to evaluate marine invertebrate movement is growing, but novel attachment methods include unknowns...

The shallow, coastal regions of the world’s oceans are highly productive ecosystems providing important habitat for commercial, forage, endangered, and iconic species. Given the diversity of ecosystem services produced or supported by this ecosystem, a better understanding of its structure and...

Spatial distribution of the relative occurrence of Spotted Wolffish in the annual DFO groundfish research surveys conducted by the Québec (1978-2008) and Gulf (1971-2008) regions. Catch and effort data were aggregated by 100 km² cells. The probability of catching an Spotted Wolffish in a set...

Spatial distribution of lumpfish catch rates (number per tow) during the August DFO research survey conducted annually since 1990, to assess the state of groundfish and shrimp stocks in the northern Gulf of St. Lawrence. The area sampled by a tow is the product of the distance trawled (fishing...

From August 5th to September 3rd, 2012, Fisheries and Oceans Canada conducted a baseline survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope. Sampling was conducted from the F/V Frosti at 28 stations along four transects. Standardized sampling was conducted at...

Catch, effort, location (latitude and longitude), and associated biological data from groundfish multi-species longline surveys on the southern British Columbia coast, excluding the inlets and protected waters east of Vancouver Island. Introduction The Outside South Hard Bottom Longline...

Striped Bass critical habitat (St. Lawrence estuary population) defined by the analysis of available knowledge in 2011 and a scientific advice. Purpose The status of the Striped Bass population of the St. Lawrence Estuary is in constant evolution. It went from indigenous population until the...

Spatial distribution of the Thorny Skate presence expressed by catch weight based on the annual Department of Fisheries and Oceans (DFO) groundfish research surveys realised between 2004 and 2010. Catch data (kg/nautical mile) were aggregated by 100 km² cells. They are derived from processed...

Map of harbours critical to fishing and aquaculture industries managed by harbour authorities (Core fishing harbours), harbours that support fishing and aquaculture industries that aren’t managed by harbour authorities (Non-core fishing harbours), and harbours that support the recreational...

The Fish Pathology Program (FPP) located at the Pacific Biological Station in Nanaimo has been assessing the health of aquatic animals since the early 1970’s. Utilizing traditional diagnostic methods, the FPP has supported internal and external clients to provide clinical data and management...

Likelihood of Presence of Bottlenose Whales in the Bay of Fundy and the Port Hawkesbury Area Response Plan. The Coastal Oceanography and Ecosystem Research section (DFO Science) reviewed reported opportunistic whale sightings and local knowledge sources to estimate areas where Northern Bottlenose...

A research survey on snow crab (Chionoecetes opilio) was conducted from May 2006 to May 2009 in the Bay of Ste. Marguerite near Sept-Îles, Quebec. The main objective of this survey was to assess the abundance of snow crab and benthic species associated with snow crab habitat. Only data for...

The spatial planning framework for Canada's national network of Marine Protected Areas (MPAs) is comprised of 13 ecologically defined bioregions that cover Canada's oceans and the Great Lakes. Note that the geographic boundaries for the bioregions are fuzzy and may change based on ecosystemic...

Rocky Mountain Ridged Mussels (Gonidea angulata) are listed under the Species at Risk Act (SARA) as a species of special concern and have been re-assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as endangered. These fresh water mussels are only found in Canada in...
