Length-frequency distribution of Arctic cod detected in different ice concentrations. Length distribution in the depth intervals of 12–20 m and 12–200 m on a log10-based scale measured as target strength (TS, top x-axis) of targets detected at 38 kHz. The bottom x-axis provides the estimated standard length (SL) of Arctic cod based on TS (TS = 14.33 log10 [SL]–65.13; Geoffroy et al., 2016). Values for n are the number of targets detected. The size range of the Arctic cod ingested by northern fulmar (NF), black-legged kittiwake (BLK) and thick-billed murre (TBM) is presented. DOI: https://doi.org/10.1525/elementa.339.f4
