Abundance estimates of fishes from Acoustic-trawl surveys of the US sector of the Chukchi Sea continental shelf conducted in 2012 and 2013.These surveys are described in De Robertis, A., Taylor, K., Wilson, C., and Farley, E. 2017a. Abundance and Distribution of Arctic cod (Boreogadus saida) and other Pelagic Fishes over the U.S. Continental Shelf of the Northern Bering and Chukchi Seas Deep-Sea Research II, 135: 51-65. http://dx.doi.org/10.1016/j.dsr2.2016.03.002De Robertis et al. 2017a applied calculations used selectivity relationships fromDe Robertis, A., Taylor, K., Williams, K., and Wilson, C.

Corrigendum to: “Species and size selectivity of two midwater trawls used in an acoustic survey of the Alaska Arctic” (Deep-Sea Res. II 135 (2017) 40-50). Deep Sea Research II https://doi.org/10.1016/j.dsr2.2021.104997.These files contain abundance data from De Robertis et al., 2017a reprocessed to use the corrected selectivity values given in table 1 of De Robertis et al., 2021.The abundance change to only a small degree (see De Robertis et al., 2021). These revised data should be used in future studies. We have also provided estimates of walleye pollock abundance that were not included in the original publication - these were computed with the methods described in De Robertis et al., 2017a,.Changes in second version posted to Mendeley data ( files marked v4)increased numerical precision of positions in csv filesAdded UTC timedata are summarized in 0.5 nautical mile along-track intervals*along_track_summary*.csv - overall summary for all speciesLatitude - degrees NLongitude - degrees WBottom_depth - average bottom depthTime_UTC - date/timeFish_38_kHz_sA - ...
