HX230 Data set changed Differential GPS indicator added , line 24 HX235 Removed Differential GPS Indicator, Line 24 now equals temp frequency. HX239 Relative humidity is not functioning HX239 Winch data added to Dasylab files HX244 seachest fluorometer cleaned between prior to cruise and twice during cruise. First cleaning was not logged and occured around EXP 11 Second Cleaning of the fluorometer was prior to file hx244_23.ASC (data collection to file hx244_22.ASC was stopped flourometer was cleaned and Hx244_23.ASC starts with cleaned fluorometer) HX248 Cond probe changed 369 removed 367 added 8/1/001 11:21 AM GMT hx249_03.ASC HX252 Seachest Flurometer SN275 was replaced by SN88 off of old MOCNESS unit Hx252B Weather packs removed for repair 10/18/2001 Hx253 Weather packs reinstalled relative humidity is working HX257 Port side weather pack wired in 1.
