The objective of th<\/SPAN>e<\/SPAN>study was to describe the spatial distribution of krill in eastern Canadian waters using a statistical modelling approach in support of the identification of important habitat for the western North Atlantic (WNA) blue whale (Balaenoptera musculus). Generalized Additive Models (GAMs) were used to predict \u2018Significant Aggregations of Krill\u2019 (SAK), i.e., areas where dense krill aggregations would have a greater probability of occurring. SAK cover less than 2% of the entire spatial domain and their location varied among krill categories and seasons. These SAK are interpreted as areas where environmental conditions promote krill aggregation on a regular basis and therefore are potentially important for WNA blue whale foraging in eastern Canadian waters.<\/SPAN><\/P>

#FRA L\u2019objectif de <\/SPAN>l'<\/SPAN>étude <\/SPAN>était <\/SPAN>de décrire la distribution spatiale du krill dans les eaux de l\u2019est du Canada à l\u2019aide de modèles statistiques, un travail réalisé en support à l\u2019identification de l\u2019habitat de la baleine bleue (Balaenoptera musculus) de l\u2019ouest de l\u2019Atlantique. Des modèles additifs généralisés (MAGs) ont été utilisés pour prédire les \u2018Régions d\u2019Aggrégation Significatives de Krill\u2019 (RASK), i.e. les régions où la probabilité de rencontrer des essaims denses de krill est la plus élevée. Ces RASK sont considérées comme des régions où les conditions environnementales permettent la formation d\u2019essaims denses de krill sur une base régulière, représentant ainsi des régions potentiellement importantes pour l\u2019alimentation de la baleine bleue de l\u2019ouest de l\u2019Atlantique.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 4269, "latestWkid": 4269, "xyTolerance": 8.983152841195213E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 9.999999999999999E8, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "copyrightText": "Plourde, S., Lehoux, C., McQuinn, I.H., and Lesage, V. 2016.
