Atlas of Seabirds at Sea in Eastern Canada 2006 - 2020

Atlas of Seabirds at Sea in Eastern Canada 2006 - 2020 The atlas provides printable maps, Web Services and downloadable data files representing seabirds at-sea densities in eastern Canada. The information provided on the open data web site can be used to identify areas where seabirds at sea are found in eastern Canada. However, low survey effort or high variation in some areas introduces uncertainty in the density estimates provided. The data and maps found on the open data web site should therefore be interpreted with an understanding of this uncertainty. Data were collected using ships of opportunity surveys and therefore spatial and seasonal coverage varies considerably. Densities are computed using distance sampling to adjust for variation in detection rates among observers and survey conditions. Depending on conditions, seabirds can be difficult to identify to species level. Therefore, densities at higher taxonomic levels are provided. more details in the document: Atlas_SeabirdsAtSea-OiseauxMarinsEnMer.pdf. By clicking on "View on Map" you will visualize a example of the density measured for all species combined from April to July - 2006-2020. ESRI REST or WMS map services can be added to your web maps or opened directly in your desktop mapping applications. These are alternatives to downloading and provide densities for all taxonomical groups and species as well as survey effort. 2023-11-02 Environment and Climate Change Canada Matthieu.Beaumont@ec.gc.ca Nature and EnvironmentScience and TechnologyScientific informationAnimalsAquatic birdsAnimal migrationsNature and BiodiversityNational (CA)Assess Status of SpeciesDevelop Species Recovery / Management / Conservation PlansProtect Species Well-BeingExpand Scientific Knowledge / Develop New Methodologies for Assessing Site ConditionsSpeciesCanadian Wildlife Service1.1.3.
