Description

Scientific sampling event log.

Methods & Sampling

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.

Data Processing Description

data version 1: 2009-03-28
data version 2: 2009-09-23
* Separate event logs were combined by the BCO-DMO to form one data file for the cruise.
* Modifications to original event log made after consultation with Chief Scientist and review of Deck Operations Log:

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.
