Species occurrence data from four abundance surveys (2002, 2007, 2011 and 2015) were modelled against the environmental variables; depth, substrate and primary production using generalized additive models (GAM) and Maxent.
Gögn um magn og útbreiðslu tegundarinnar úr fjórum sýnatökum (2002, 2007, 2011 og 2015), ásamt umhverfisbreytunum dýpi, gerð undirlags og frumframleiðslu, voru sett í GAM (Generalized additive models) og Maxent líkön.
