The goal of our quality control (QC) is to provide well-documented,
reliable, and consistent research vessel data to the scientific community.
Data are evaluated using both automated and visual QC and flags are applied
values at the parametric level. This means that each individual observation
(for which QC is applied) will have a single alphabetic quality control
flag. Our philosophy is to flag suspect values, not remove them from the
data files. Accepting or excluding some flagged values may vary depending
on the user's scientific goals, and our system retains all values for that
