Sampling Manual

The use of these sampling tools and the treatment of the samples are detailed explained in the “Sampling Manual” for the Joint Annual Norwegian-Russian Ecosystem Survey in the Barents Sea” in August-October. This manual includes the metrological and technical issues, describes equipments, the trawling and capture procedure by the samplings tools being used during the survey, and present the methods that are used in calculating the abundance and biomass for the biota. This Sampling Manual has been developed since 2004 and published on the Ecosystem Survey homepage by specialist and experts from IMR and PINRO in 2012. This report is also in a process of being continuously updated.
