3
20190129915Cleaned fluor and trans.
4
201901161145pCO2 sensor brought into lab, rinsed with freshwater and air-dry. Looks like water under the membrane. Emailed Turner.pCO2 sent back to manufacturer on..
5
201901152000pCO2 drifted up to 1800 from 600ppm. Unknown reason.
6
20190115Swapped SUNA 1112 for SUNA 1111.See grab sample spreadsheet for cal check notes
7

8
20190111Odd fluctuations in DO/%saturation in SWI also seen in the old "industrial seawater" DO sensor. Suggests an issue with backwashing or air leaking into raw seawater line. I don't see that happening in the Aquarium Room tho.
9
201901091145Cleaned fluoro and trans; really low flow.. adjusted to 3lpm
10
20180107Checked flow.. a little low but ok. Adjusted to 2lpm
