Sampling Methodology
DMO note on calculated depth
AESOPS Investigators, Please note:
Begin and end parameters for time, latitude and longitude are
provided in the core CTD and Bottle data. Investigators
submitting data related to CTD/Bottle casts are urged to use
the single lat/lon entry from the Chief Scientist's event log.
Parameter Description Units
event a unique number assigned to each sampling
operation consisting of month MM, day DD
hour HH and minute mm
sta station number
