20170914morningDived and cleaned the intake pipes & screens. Lots of growth on the screens, so brushed them thoroughly.
3
20170911All day Noticed flow issues in the data this morning. Cleared biofouling and cleaned: pCO2, CTD, DO, and pH probes
4
20170829Some data lost during updating of pCO2 data processing. Updated pCO2 to correct for total dissolved gas pressure in water
5
20170811pCO2 data back to real-time!
6
20170718 evening to next morningTubing to pH sensor came detached. No flow to pH sensor. All other sensors recieveing ok flow.
7

31
201702071100Cleaned fluoro and trans
32
20170121 - ongoingData spikes caused by hourly backflushing of the sand filters. Major swell event on 2017-01-25 could have damaged or covered intake opening, causing pumps to draw in sediment.I dove on the intakes and found no damage. Highly turbid water coming from the river is fouling up the sand filters. Problem resolved itself over the course of several days.
33
