Data Object event_log
Shipboard sampling events were logged in two separate Excel spreadsheets, one for the CTD/Niskin bottle rosette package and a second for the Trace Metal (TM) rosette package.
Separate event logs were combined by the BCO-DMO to form one data file for the cruise.
BCO-DMO retrieved missing data as needed from the original deck operations bridge log.
Station 13 cast 23 longitude taken from the navigation track data.
Station 6 TMR cast 11: event 11230908 start date changed from 11/22 to 11/23 and start time entered as 0900 GMT.
