Ziel der Reise / Objectives of Cruise:

Cruise objectives: 1. To participate in the German Small-scale Bottom Trawl Survey (GSBTS) to monitor the fish fauna in 6 out of 12 small areas (boxes). 2. To investigate the hydrographical conditions within the boxes (vertical distribution of temperature, salinity and turbidity). 3. To calibrate the low-light stereo cameras used in the UFO-Project with the RAMSES-ACC-VIS (Hyperspectral UV-VIS Irradiance Sensor - 320 - 950 nm). Narrative: On the 18th of July 2014 Solea left Cuxhaven and started the following day in Box K (German Bight) the scientific program. In general, the scientific program comprised three days with 7 hauls a day per box together with three CTD measurements and three measurements with RAMSES. The spectral radiometer was borrowed from the working group of Prof Martin Wahl (GEOMAR, Kiel). The incoming solar radiation [W/m?nm] between wavelengths of 320nm and 950nm was measured at all hydrographic stations up to a maximum water depth of approximately 25 m. The calculated (with the SAS Software) depth profiles will be used to calibrated the low light stereo cameras used in the UFO-Project (TP1 of AutoMAT, TI-SF). On Monday the 21st Solea had to stop in Esbjerk due to some technical problems. The scientific program continued from the 22nd of July until the 28th of July. On the 29th of July three members of the scientific have been exchanged in Esbjerk. The program continued from the following Wednesday 30th of July.
