This dataset was extracted from the 50-member Large-Ensemble Canadian Regional Climate Model (CanRCM4-LE) (Scinocca et al., 2015), North American region 0.44° horizontal grid resolution (NAM-44) model runs. Basin averaged means for nine river basins in Western Canada consisting of three variables: mean daily temperature (tas: K); precipitation (pr: kg m-2 s-1); and surface snow amount (snw: kg m-2) are provided.

These data were created under DFO’s Strategic Program for Ecosystem-based Research and Advice - Aquatic Invasive Species Program: “Evaluation of the movement of marine infrastructure as a pathway for aquatic invasive species spread”. This geodatabase contains floating dock locations in coastal waters of the Pacific Northwest, from Puget Sound, Washington to Southeast Alaska. These data were assembled by Josephine Iacarella and used in an analysis to understand the role of floating infrastructure as a vector in the spread of marine nonindigenous species (Iacarella et al., 2019). The data are represented as point vectors, though docks have associated size estimates.

Herb willow is dominant Arctic-alpine plant in snowbeds and, being a low-growing species, could potentially be crowded out if southern species colonise these sites. Herb willow is being monitored at 14 snowbeds in Gros Morne. At each snowbed willow is sampled along a 1 m x 15 m permanent strip transect. These data are used to calculate a herb willow % cover index, a herb willow incidence index.

Existing invasive exotic species and the potential introduction of new invasive species pose a threat to forest biodiversity and function. The PEI National Park invasive species composite measure consists of two annual field measurements: the percentage of forest ecosystem with invasive species present (measured by proportion of 244, 441 m2 quadrats covering the forest ecosystem), and the percentage of total forest area (ha) with invasive species present. The measure includes four invasive plants and one insect: Garlic Mustard (Alliaria petiolata), Japanese Knotweed (Polygonum cuspidatum), Scots Pine (Pinus sylvestris), and Glossy Buckthorn (Frangula alnus), and Gypsy Moth (Lymantria dispar), which is measured for presence only.

This data was produced under contract for Alberta Agriculture and Forestry, Forest Management Branch in 2015-2016. Variables used were elevation, aspect, slope, landscape mesotopography (e.g. ridge, upper slope, etc). DEM was used where there was no LiDAR coverage, with a resolution of 25 m2 pixels.

Changes to tundra vegetation communities may affect local ecological processes such as nutrient cycling and quality and quantity of animal forage. In Quttinirpaaq National Park, the composition and relative abundance of plant functional groups are monitored using a point frame and the pin-drop (or point-intercept) method, in accordance with the International Tundra Experiment (ITEX) protocol for plant community monitoring. Baseline plant community data were collected for 20 x 1 m2 permanent plots, located in mesic tundra habitat near Tanquary Fiord, on a biennial basis between July 2012 and July 2017. As the baseline data collection has been completed, plant community monitoring at Tanquary Fiord will now take place every 5 years.

This index is the cumulative summation of negative northwesterly atmospheric circulation frequency anomalies: Z (westerly), M1, (northwesterly), and M2 (southwesterly) for December through March. An increasing trend in Pacific Circulation Index (PCI) reflects increased westerly and southwesterly atmospheric circulation off the west coast of Canada. Correct citation: J. R. King, V. V. Ivanov, V. Kurashov, R. J. Beamish, G. A. McFarlane. General circulation of the atmosphere over the North Pacific and its relationship to the Aleutian Low.

The purpose of this study was to characterize the kelp bed at Batture-aux-Alouettes, a preferred food source for the green sea urchin (Strongylocentrotus droebachiensis). The green urchin is fished commercially in Quebec and the fishing effort is concentrated on the Batture-aux-Alouettes near Tadoussac, at the mouth of the Saguenay Fjord. The study was conducted in two separate phases in 2018 and 2019. The main objective of this study was to determine the abundance and biomass of the kelp bed at Batture-aux-Alouettes.

Geographic bathymetric grid data at 100 m x 100 m pixel resolution. Datum: WGS84

Collaboration of Canada, the United States of America and the European Union as part of the Atlantic Ocean Research Alliance's fifth project under the Galway Statement. Project mapped the North Atlantic seafloor along a transect from Halifax, Canada to Tromsø, Norway to further the understanding of marine habitats, conservation and navigation. Chief Scientist / Primary Investigator name: Paola Travaglini

Platform: CCGS Louis S. St- Laurent (Canadian heavy icebreaker)

Device 1 type: Multibeam echo-sounder (sonar)

Device 1 manufacturer: Kongsberg

Device 1 model: EM122 behind an ice protection window

Data and Data format:

100 m resolution grid of bathymetry

BAG format: Bathymetric Attributed Grid Object

Navigation and positioning:

 Trimble GNSS receiver + antennae
