Knowledge of the scattering properties of Antarctic krill (Euphausia superba) is crucial for biomass estimates of the species, but in situ investigations regarding this are still very scarce. We conducted a field study in the Southern Ocean where one of the objectives was to acquire data on orientation angles and target strength of Antarctic krill. The main investigations were done off South Georgia and the Bouvet Island and we here in part present the methods applied and give examples of data acquired. The post-processing and analyses are ongoing and the results from this work will be presented in future reports.
