Integrated hull-mounted acoustic data 38 kHz IMR cruise 2018106

The dataset contains integrated values of total and mesopelagic backscatter for an EK60 38 kHz echosounder, from ~25 to 1000 m depth, collected during June 2018 during a Norwegian cruise aimed at mapping mesopelagic resources. Data is based on integration of data cleaned with automatic filters using KORONA, and manual cleanup of remaining problems (false bottoms etc.). All backscatter deeper than 200 m were then assigned to the mesopelagic category, with backscatter shallower than 200 m reported in the total category.
