Status of the FIBEX acoustic data from the West Atlantic
Data from the FIBEX acoustic survey in the West Atlantic sector have been re-examined to check the consistency of krill abundance estimates derived from different survey vessels. There is a good level of consistency between the results from four of the vessels, Itzumi, Dr Eduardo L. Holmberg, Odissey and Walther Herwig. While there is an error factor due to the combination of data collected at 50 kHz (Walther Herwig survey) with data collected at 120 kHz (all other vessels), it is concluded that this does not materially affect the estimated biomass.The data from the Professor Siedlecki survey do not provide estimates that are consistent with the other surveys. The authors can find no explanation for this difference.
