The dataset represents known concentration areas of harvested or unharvested Softshell clam (Mya arenaria) in the intertidal zone of the Estuary and the Gulf of St. Lawrence, Quebec region. The dataset was created for the National environmental emergencies centre (NEEC) for preparation and...

Spatial distribution of the Winter Skate relative occurrence based on the annual Department of Fisheries and Oceans (DFO) groundfish research surveys realised between 2004 and 2010. The probability of catching a Winter Skate in a set and within a cell (relative occurrence) was calculated as the...

Marsh inventory in the Chaleur Bay, the Estuary and the Gulf of St. Lawrence according to a literature review of documents produced between 1985 and 2002. Additional Information The marsh inventory was produced according to a literature review of the following documents: Bolduc, F. et P....

Available information for the Estuary and Gulf of St. Lawrence on salinity, temperature, dissolved oxygen, depth, slope, and variability in landscape and sediments, were aggregated using a grid made up of 100 km2 cells as a basis for mapping and describing marine habitats for conservation and...

The Copper Redhorse (Moxostoma hubbsi) is the only fish whose distribution is exclusively restricted to Quebec. This range is restricted even further to the St. Lawrence River and some of its tributaries. This layer represents the Copper Redhorse critical habitat defined by the analysis of...

To identify areas of high residency, fine-scale tracking data from individual animals and coarser, short-term movement patterns of herds were analyzed. Individual radio-tracking was assessed from 2001 to 2005 and herd visual tracking was assessed from 1989 to 2008. Data was collected by two...

A geospatial database involving 130 descriptors was created describing the pelagic and benthic habitats of the 0–30 m surface layer in the estuary and Gulf of St. Lawrence. A grid made of 6.25 km² cells (2.5 x 2.5 km) was used to aggregate the data. Each of the 39,337 cells overlapping the...
