I arrived about 9:45 with Sara. Heavy fog was lifting and there was little to no wind. Quite a few birds around.

We pulled the water CO2/DO stringer. We collected data from the miniDOTs and swapped two of the Forerunner CO2 probes. The CO2 probes in the bottom sn GP20140025 and middle sn GP20140024 came off and sn GP20140023 went in the bottom location and sn GP20140026 went in the middle location. The probes that were swapped in have copper mesh glued over their filters.

The 7700 read: 2.212ppm, 31.5RSSI â€“ 63.0 after cleaning
The 7500 read: 399.8ppm CO2, 593.0mmol/m3 H2O, 95.7SS, 10.72C, 101.67kPa â€“ 102SS after cleaning

We tried to install the Tule PAR but it was reading 10mV. We removed it again for testing in the lab.

The atmospheric pressure sn 4505052 was reading 109kPa. We removed it for testing in the lab.

The Tule IRT was pointed at the boom. I tried to repoint it at the tules but the mount needs help.

Sara collected water samples.

I replaced the screw terminal on the HMP45 fan. The fan seemed to work after the connector was fixed.
