Designed and assembled in Canada, Alouette-1 was the first satellite built by a nation other than the United States or the Soviet Union. It was constructed at a time when most satellites had a useful lifespan of a few months. Although Alouette-1 was as complex as any previously launched satellite, rapidly advancing technology and the extreme care exercised in all phases of Alouette-1’s development had led the Canadian builders to expect that their satellite would operate for at least 1 year. However, Alouette-1 operated for 10 years.

This program measures kelp density from annual dive transects during August and September at a number of sites in the Broken Group Islands of Pacific Rim National Park Reserve. Kelp species assessed include Agarum spp., Macrocystis pyrifera, Eisenia arborea, Pterygophora californica, Saccharina spp. and Desmarestia spp. Kelp forests are phyletically diverse, structurally complex and highly productive ecosystems in temperate rocky marine coastlines, thereby providing a suitable suite of measures indicative of subtidal ecosystem health.

This dataset is a contribution to the development of a kelp distribution vector dataset. Bull kelp (Nereocystis leutkeana) and giant kelp (Macrocystis pyrifera) are important canopy-forming kelp species found in marine nearshore habitats on the West coast of Canada. Often referred to as a foundation species, beds of kelp form structural underwater forests that offer habitat for fishes and invertebrates. Despite its far-ranging importance, kelp has experienced a decline in the west coast of North America.

This program focuses on capturing the abundance and structure of groundfish communities typical of nearshore kelp forests including Black Rockfish (Sebastes melanops), Copper Rockfish (Sebastes caurinus), Kelp Greenling (Hexagrammos decagrammus) and Sea Perch: Kelp Perch (Brachyistius frenatus), Pile Perch (Rhacochilus vacca) and Striped Perch (Embiotoca lateralis) combined. Surveys were completed annually in August and September at sites within the Broken Group Islands and consisted of a transect through a kelp forest patch at approximately 10m depth. Surveys began in 2008 and changed methodology in 2013 from a 2 diver survey (2 surveyors along a 25m long by 4m wide band transect) to a 1 diver survey (1 diver along a 30m long by 2 m wide band transect). This data is used to determine the status and trend in kelp-forest associated fish, including fish abundance and the effectiveness of the Rockfish Conservation Areas (RCAs) on fish abundance.

Distribution of kelp beds in coastal British Columbia. Attribute information includes relative abundance, species, biomass and density of the beds. CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts.

Kelp features were taken from digitized survey source fieldsheets produced by the Canadian Hydrographic Service (CHS). The area covered by this dataset encompasses various surveyed areas along the western coast of North America in British Columbia coastal waters. CHS has an extensive collection of hydrographic survey data in the form of field sheets based on over 100 years of surveying in Canada. Data has been collected using a wide range of methods and systems, from lead-line to modern day multi-transducer and multibeam systems.

This dataset concerns monitoring of the Penouille eelgrass beds. Because of the ecological importance not only of eelgrass beds, but also of the animal communities they support, eelgrass beds are often used as indicators of coastal ecosystem health. Two sets of data deal more specifically with animal species, mainly fish, which use this habitat for different stages of their life cycle. They contain data related to each of the three sites sampled in the spring and fall using fyke nets since 2013.

Park staff monitor invasive wetland plants at marsh monitoring sites in May-June each year (8 plots/year). In each wetland, pairs of 1 m x 1 m quadrats placed 2 m apart are sampled along 3 transects at 5 and 15 meters in wet meadow, emergent and submergent vegetation zones. The percent cover is recorded within each quadrat for 10 exotic invasive plant species including European Common Reed, European Frogbit and Purple Loosestrife.

The Grasslands National Park samples Sage Grouse habitat in a series of randomly located plots in upland grassland and valley grassland ecotypes within an 8 kilometer radius of an active lek. At each plot, a 100 m transect is established, with 24 evenly spaced quadrats.

At offshore sites, triplicate Ponar grabs (0.052 m-2) of sediment were collected from the M/V Namao. At nearshore sites, sediment samples were collected from a smaller workboat using a Petite Ponar grab (0.023 m-2) at the 3 m depth contour. Total sampling effort varied across the three years owing to time and logistical constraints (see Supplemental Table S1 for additional detail). Additional samples were collected at up to 18 shoreline sites (depths ranging from 0.2 - 1.0 m) around the lake in 2019.
