Ziel der Reise / Objectives of Cruise:

Objective: International acoustic survey for pelagic fish stocks in the North Sea At June 28 FRV "Solea" left Cuxhaven port and steamed towards position (54? 09,983'N, 007? 57,344'E) were the calibration was carried out at the next day. Finishing the calibration the survey started at the 29-06-17 at the position 54? 30,178'N. 007? 48,383'E. The investigations were done during day time from 0400UTC - 1800UTC (however, some exceptions were made). The acoustic equipment was the new echosounder EK80 with the hull mounted transducers. All availabel frequencies were recorded in the CW-mode ( ES 38-7, ES 70-7C, ES 120-7C and ES 200-7C), however only 38 kHz were used for the stock estimation. The weather conditions were mediocre. In the evening of July 17th FRV "Solea" entered Cuxhaven harbor after covering 2205 NM of hydroacoustic transects. Altogether, 28 fishery hauls with a pelagic trawl net PSN 388 "Krake" and 70 CTD casts were conducted. The scientific crew left the ship on 18,07.17 and went home.
