Canadian Hydrographic Service (CHS) has made available all the publishable limits of modern day surveys whose data has been collected since 1989.

To assess the current distribution of kelp beds and other macroalgae in Nova Scotia and Southwest New Brunswick, subtidal drop camera surveys were performed from 2022-2023 at 140 sites. For each site, a GoPro HERO 10 camera was towed along a deep (7-12m) and shallow (3-5m) depth contour until 20 images were acquired per depth. Where possible, species were identified from photos, with particular care given to kelps (defined here as orders Laminariales and Tilopteridales) and fucoids (order Fucales). Crust-forming algae was not counted. Percent cover was calculated using a 10x10 point grid overlaid on each image and recording the dominant cover type at each point. The depth (in meters) of each photo after correcting for tide height ranged from ~0.5m to ~12m. Depths were corrected to chart datum (lowest astronomical tide) using tide predictions from the nearest tide station, taken from tides.gc.ca. Sampling was performed between July and October.

This spatial layer displays lakes that have had full or partial surveys, and contains information regarding the dates of those surveys and an indication of the data collected on each survey date

The "Canadian Database of Geochemical Surveys" has two long-term goals. Firstly, it aims to catalogue all of the regional geochemical surveys that have been carried out across Canada, beginning in the 1950s. Secondly, it aims to make the raw data from those surveys available in a standardised format. Over 1,500 surveys have been catalogued. Of these, the raw data for over 300 have been converted to a standardised format. The catalogue can be searched at https:\\geochem.nrcan.gc.ca

Surveys include information related to diamond drilling.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Fisheries and Oceans Canada (DFO) has been conducting surface water trawl surveys since 1992 in the coastal waters of British Columbia, Washington, Oregon and Alaska and in the high seas of the Gulf of Alaska. These surveys initially focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2016) of juvenile Pacific Salmon. Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. Surveys have been conducted on the continental shelf of north and west Vancouver Island, included associated sounds and inlets since 1992 and are ongoing. These data are for tows conducted in the continental shelf area for depths shallower than 400 meters.

Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. In this record, surveys were conducted in continental slope waters at depths greater than 400 m out to the Gulf of Alaska, between 1995 and 2011. Periodically, there are tows from surveys conducted in other regions that occurred on the continental slope and they are included here. This set of data also includes data collected during the International Year of Salmon survey in 2022.
