The SBE DO sensor has a fairly long response time so data accuracy is not as high when it is in motion as it is during stops for bottles. This will be especially true when vertical DO gradients are large. There was insufficient sampling of dissolved oxygen to estimate such errors. Channel pH:SBE was removed from event #2 and #81 since the cap was accidentally left on.
