All time specifications in Central European Summer Time (CEST = UTC + 2)
v Specifications regarding fixed stations, ship stops for vertical CTD profiles and
water sampling
ScanFish
Specifications regarding transit stations where water samples for radioactivity are
taken from the sea water pipe during transit
SF> Start of ScanFish profile

W&S Weather & Sea: Ta = air temperature, Tw = water temperature at 4 m depth
RA — Radioactivity, sea water samples are taken for the following artificial nuclides: Cs-
137 = cesium-137; Sr-90 = strontium-90; Pu = plutonium, H-3 = tritium
There are no data from the Seabird thermosalinograph SBE 21 available due to a blocked
outlet and also no air temperatures due to sensor problems!

58:00: Arrival at Celtic Explorer, shed 72 (Kaiser-Wilhelm-Harbour)
08:30: Mobile crane arrives.
Three TV teams came on board (Hamburg 1, RTL Nord, Sat.1), interviews with chief
scientist and crew. Telephone interviews with WDR.
11:30: Arrival of container and material, start of mobilization.
W&S 12:30: Bft. 2, 179°, 1012 hPa, clear sky.
17:30: Activities requiring the external mobile crane are finished.
The winch for Clean-CTD was installed in front of dry lab. Both ScanFish winches
have been equipped with a new Rochester coax cable, 8.18 mm (Signal
Transmission Cable, Code: SC0010132CO00, Part No. A320327) after the last cruise
ın 2013. We expect to reduce the electrostatic problems which occurred during the
ScanFish launches during the last surveys. Further on we decided to reduce the tow
velocity to 8 kn (trough water, not over ground').
18:30: Security instructions by the second mate Barry Hooper.
19:19 Short meeting of the marine physics group for a review of the work to be done in the
next days: The new wire on both winces must still be terminated which needs 36
hours. the Cruise Assistance System has to be adopted to the new data distribution
