September 12 2018: The report from the AEWG in May is now available
The aim of the Working Group was to consider abundance estimates of cetaceans in the North Atlantic, particularly from the most recent NASS in 2015, but also from previous and more recent surveys. New abundance estimates from the surveys in 2015 and 2016 as well as from older Norwegian mosaic surveys were therefore presented to the Working Group. The new estimates have been accepted for some species, while the Working Group provided advice for improving other analyses. Formal cooperation has also been established between the NAMMCO Scientific Working Group on Abundance Estimates and the newly formed IWC Working Group on Abundance Estimates.
