A field intercomparison between a miniature CTD and the Neil Brown serial 1223 CTD- profiler
During a survey in Lofoten in may 1989 a new miniature CTD which is being developed at the Inst. of Marine Research was mounted to the ship`s ordinary serial 1223 CTD- profiler on 10 different CTD- stations. Using the NB CTD as a reference and compensating for differences in sampling rate, the data...
