4. Spatial distribution of Champsocephalus gunnari in Subarea 48.3. Some implications for parameter estimation

   Abstract:  Results of the analysis of three consecutive cruises to subarea 48.3 are analyzed. A ... significant variance component associated with the formation of clusters of stations was found as well as a ...
