In the evening, after station GNO26N, while steaming to the west, wind from the 
west steadily increased. Very uncomfortable to go against rough sea. During 
the night the speed was reduced to a minimum of 2 kn.

the evening wind calmed down and sea conditions started to level out.

Between GN030 und GN031 the pH-sensor was changed, as large differences 
between down- and upcast were visible. Anyway, the situation is unchanged, as 
the elektrolyte liquids of both sensors are clouded and must be renewed.

improved!
