The data submitted is used in a comparative analysis of the diet of one of the globally most numerous myctophids, the Glacier lantern fish Benthosema glaciale, across four deep basins of the North-Atlantic. B. glaciale is a small fish species that contribute to carbon flux to the deep basins of the open ocean, and is thus considered an important element of the biological carbon pump (BCP). Data submitted is length and weight of fish analyzed for stomach content. In addition there are available taxonomic information, weight and number of prey items of each fish that has stomach content, as long as it has been possible to assign prey to a species or other taxonomic category. Unidentified prey usually had a high degree of digestion and individual items could not be counted, but could be weighed. Sampling were undertaken onboard the RV G.O. Sars during a six week long transatlantic scientific survey from Bergen (Norway) to Nuuk (Greenland) and back to Bergen in May and June 2013. Samples of B. glaciale for ... : Funding and ship time were also received from the Institute of Marine Research, Bergen, Norway. ...
