Abundance estimates from West Greenland March-April 2006 are corrected for availability with a(0) = 0.18 (CV = 0.04), and sightings from stratum 11 were included in the calculation of the detection function and mean group size only. Abundance estimates for Melville Bay and Inglefield Bredning in August 2007 are corrected for availability bias with a(0) = 0.21 (CV = 0.09). Abundance estimates for East Greenland in August 2008 are corrected for availability bias with a(0) = 0.21 (CV = 0.09). Sightings were truncated at 800 m. The encounter rate and density estimates for "All" strata include strata where no whales were detected. Number of sightings is after truncation, CV = coefficient of variation. ...
