Graphic illustrations of the major ecosystems in the Pacific region, including details on the main ecological components, key ecological interactions, environmental drivers, and relevant human activities. Ecosystems range from the intertidal to the deep sea and include: High and low energy rocky...

Description: Seasonal climatologies of the Canadian Pacific Exclusive Economic Zone (CPEEZ) were computed from a numerical simulation of the British Columbia continental margin (BCCM) model for the 1993 to 2020 period, which can be considered as a representation of the climatological state of...

Description: Seasonal climatologies of the Canadian Pacific Exclusive Economic Zone (CPEEZ) were computed from a numerical simulation of the British Columbia continental margin (BCCM) model for the 1981 to 2010 period, which can be considered as a representation of the climatological state of...

AVHRR Pathfinder version 5.3 Level 3C night Sea Surface Temperature (SST) was acquired from NOAA at 4 km spatial resolution. The monthly mean value at all pixels was calculated for individual years, then all years were combined to produce final maps of monthly mean and monthly standard deviation...

The data in the files of this dataset represent the raw and standardized information of the distribution of the number of prey in stomachs of larval fish, the increments widths derived from larval fish, and the mortality rates, that were included in the study by Pepin (2024) into the probability...

Fisheries and Oceans Canada (DFO) Maritime Science Branch has collected grain size data from sediment and water column samples using bottle samples, sediment cores, and sediment grabs as part of numerous research projects not only in the Atlantic provinces, but also worldwide. The data collected...

PURPOSE: Determine the stock status of southern Gulf of St. Lawrence Atlantic Cod. DESCRIPTION: The yearly spawning stock biomass estimates of southern Gulf of St. Lawrence Atlantic Cod were obtained using a Statistical Catch-at-Age model as part of the stock assessment to year 2023. The...

Description: Seasonal mean primary production from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period and depth-integrated to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Total primary production is...

Description: Seasonal mean salinity from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Salinities at up to forty-six linearly interpolated vertical...

Description: Seasonal mean temperature from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Temperatures at up to forty-six linearly interpolated...

Description: Seasonal mean dissolved inorganic carbon concentration from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Dissolved inorganic carbon...

Description: Seasonal mean total phytoplankton at the surface from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean surface climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Total phytoplankton is the...

Description: Seasonal mean aragonite saturation state from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Aragonite saturation states at up to...

Description: Seasonal mean pH from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: The pH at up to forty-six linearly interpolated vertical levels...

Description: Seasonal mean total alkalinity from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Total alkalinities at up to forty-six linearly...

Description: Seasonal mean oxygen concentration from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Oxygen concentrations at up to forty-six...

11 tagged Blue whales (Balaenoptera musculus) were tracked during the daytime movements as well as the feeding behaviour in the St. Lawrence River estuary. Kernel density was applied to derminate the high density feeding areas of all individuals combined (30, 40, 50, 60, 75, 95 %)....

Description: Seasonal mean current speed from the British Columbia continental margin model (BCCM) were calculated as the root mean square of the zonal (U) and meridional (V) velocities and averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific...

Description: Seasonal mean nitrate concentration from the British Columbia continental margin model (BCCM) were averaged over the 1993 to 2020 period to create seasonal mean climatology of the Canadian Pacific Exclusive Economic Zone. Methods: Nitrate concentrations at up to forty-six...

Water temperature and water level are significant environmental factors affecting ecology of anadromous fish. Large-scale freshwater monitoring networks remain sparse, yet environmental protocols rely heavily on water temperature and water levels to assist decision making on river closures. Our...
