Description

CTD data from AT39-01 (North Pond 2017 expedition)

Cast at3901001 was a test cast. No bottles were fired. Pumps were turned on at a depth of approximately 27 meters. Data above this depth should not be considered valid and were removed before submission. The oxygen sensor encountered at problem at approximately 310 meters on the upcast. Oxygen data should not be considered valid between this depth and the end of the cast at 100 meters. Only the downcast data is provided here.

On cast at3901002, fouling caused intermittent pump operation in the plumbing line between the Temp1, Cond1, and Oxygen sensors. These data were manually replaced with 9.99e-29. Data from Temp2, Cond2, and all other sensors is valid for this cast.

On cast at3901009, a noticeable offset was present in the Oxygen data for the upcast, following a prolonged (12+ hour) deployment. The sensor was cleaned following the cast and values returned to normal on all subsequent casts. Only the downcast data is provided here
