Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Based on annual bottom-trawl surveys in the Barents Sea and Svalbard area in 1983-2000, variations in distribution and abundance of age 1 Greenland halibut (Reinhardtius hippoglossoides Walbaum) are described. The surveys showed high contrasts in abundance during the period, with extremely low abundance in 1990-1995 associated with a northerly displacement of the distribution within the survey area. A reduced abundance was not reflected in VPA-based estimates of total abundance of 1-group halibut. We conclude that the survey covered a varying proportion of the total distribution area. Survey abundance, the range of distribution within the survey area, and the proportion covered by the surveys were all negatively correlated with temperature in the Atlantic Water of the Spitsbergen Current. Possible mechanisms linking survey results to the physical environment are discussed.
