Abundance indices for norwegian coastal cod north of 62°N

In connection with the benchmark processes within ICES on Norwegian Coastal Cod north of 62°N during autumn 2020-spring 2021, new abundance index series based on bottom trawl stations and acoustics at the autumn coastal survey were made. The acoustic index covers the period 1995-2019 while the trawl index covers the period 2003-2019. This report describes the methods used and briefly presents the results.
