Each data value is a separate sample that is corrected against the calibration of the machine it is run on. The instrumentation is calibrated against a set of standards that are either solutions formulated by our chemists or against a standard that comes in a sealed glass ampoule from a certified lab on the mainland or Europe. A set of samples (15-50) are run on the calibrated instrumentation (machines) over a period of about 2-8 hours depending on the parameter measured.
The time of day varies, although the measurement is usually determined
between 11:00 a.m. to 4:00 p.m. Most of the samples are run fresh and not
preserved in any way, except DO's. We measure dissolved oxygen using the
Winkler Titration method, so the samples are preserved with a two chemical
process immediately after the sample is taken. The shallow intake was
between 65-70 ft. It is actually closer to 45-50 ft., which is still
probably well below influence of sunlight.
