In Canada, DFO assessments have reported a high probability of significant climate change impacts in all marine and freshwater basins, with effects increasing over time (DFO 2012a, 2012b), while climate projections indicate that ecosystems and fisheries will be disrupted into the foreseeable future (Lotze et al. 2019b; Bryndum-Buchholz et al. 2020; Tittensor et al. 2021; Boyce et al. 2022c). Despite its imminence, climate change is infrequently factored into Canada’s primary marine conservation strategies, such as spatial planning (O’Regan et al. 2021) or fisheries management (Boyce et al. 2021a; Pepin et al. 2022). The Climate Risk Index for Biodiversity was developed to assess climate risk for marine species in a quantitative, spatially explicit, and scalable way to better support climate-informed decision-making. It has been used to evaluate climate risks for marine life globally (Boyce et al. 2022a), regionally (Lewis et al. 2023), and for fisheries (Boyce et al. 2022c). These data present results from application of the CRIB framework to estimate average climate risks associated with sea surface warming across 2,959 species throughout the Canadian marine territory under contrasting future emission scenarios. In the Technical Report accompanying this data publication, we use Atlantic cod (Gadus morhua) as an example to describe the approach’s data, methods, and outputs, and to transparently and tangibly show how it quantifies risk and can inform and support climate-informed decision-making in Canada.

The 2006 Derived Interpolated Census of Agriculture by Soil Landscapes of Canada takes a subset of attributes from the 2006 Agricultural Census and creates new derived attributes that show the proportionate contribution of a variable to the total.

The toponymic features of the CanVec series include proper nouns designating places and representations of the territory. This data come from provincial, territorial and Canadian toponymic databases. They are used in the CanVec Series for cartographic reference purposes and vary according to the scale of display. The toponymic features of the CanVec series can differ from the Canada's official geographical names. The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.

The Turkey Lakes Watershed (TLW) Study was established in 1979 by several federal government departments (Natural Resources Canada, Environment and Climate Change Canada, and Fisheries and Oceans Canada) to study the impacts of acid rain on aquatic and forest ecosystems but has since expanded to include other research on toxic contaminants, forest harvesting, habitat modification, and climate change. The TLW is a mixed hardwood forest with a 10.5 km squared area in the Canada Shield that drains into Lake Superior, and has been the focus of many interdisciplinary, whole-ecosystem studies on environmental issues. Benthic invertebrates, or insects found at the bottom of waterbodies, can be key indicators of stream health and play important roles in nutrient cycling and the food chain. In 1995, a project within the TLW aimed to evaluate how stream ecosystems respond to tree harvesting, which involved long-term surveys of benthic invertebrate communities pre- and post-harvest. Three stream catchments (c31, c33, c34) were harvested at different intensities in the summer of 1997 and were compared to multiple undisturbed catchments. Alongside the invertebrate data, corresponding stream habitat surveys, streamside litterfall traps, leaf decomposition, deposition of stream particulate matter, and standing sediment bedload data was collected during the same period. The data was collected from 1995-2009 by researchers at the Canadian Forest Service (Great Lakes Forestry Centre). This dataset is a rare and valuable resource because there are very few existing long-term datasets of benthic invertebrates from the same locations, and because this dataset is integrated with other biological and chemical datasets within the broader TLW database stored at the Open Government data repository. For an overview of other types of data available from the TLW, see https://doi.org/10.1002/hyp.14109, and for a complete list of publications that have been produced from data collected at this site, see https://www.canada.ca/en/environment-climate-change/services/turkey-lakes-watershed-study/publications.html.

Towfish (sidescan and video) and echo sounder surveys were utilized to examine bottom type and macrophyte cover within the area of two coastal marine finfish aquaculture sites, one in New Brunswick (Welch Cove) and one in Nova Scotia (Jordan Bay). Both towfish and echo sounder data could be used independently of one another. However, the towfish data were very useful for ground truthing echo sounder based classifications. All survey data were placed into a GIS which could be used to answer management questions such as the placement of cages at sites, benthic impacts and baseline conditions to determine long term changes.

A novel, bay – scale (i.e. tens of km) survey method was employed to examine algal populations on the southwestern shore of Cape Breton, Canada, for the purposes of potential economic exploitation. Since traditional remote sensing methods were unlikely to be successful in these waters, underwater video and acoustic methods were applied. A transponder positioned towfish housing video camera and sidescan sonar was hauled along predetermined transects perpendicular to shore to provide information on bottom type and algal cover. The towfish data were used to ground truth echosounder data (bottom type and macrophyte canopy height) collected along 5, 10 and 20 m depth contours. The survey area was divided into six zones comprising a range of exposure, depth and bottom types. Destructive quadrat samples were collected at each depth plus shore stations to provide biomass estimates. Over thirty five taxa were enumerated, indicating depths and zones of common occurrence. Ascophyllum was abundant at some of the shore stations. The genera Chondrus, Cystoclonium, Desmarestia, Fucus, Phyllophora, Polysiphonia, and Saccharina were common at 5 m. Desmarestia and Saccharina dominated at 10 m with wet weights sometimes over 1 kg·m-2. Agarum dominated at 20 m. The towfish / echosounder grid sampling system was relatively coarse in order to cover the 140 km2 survey area within 12 days. As a result, the survey did not produce spatially detailed information. However, adequate information was gathered to describe the general characteristics of bottom type and algal cover by zone and for focusing further exploration--Abstract, p. vi.
