East End
2015-02-05

I arrived about 12:00 with Sara. The fog is lifting and there is little to no wind, but still overcast. Lots and lots of birds. Looks like someone is setting up a bunch of nesting boxes and platforms in the wetland. The water level is lower with the DO and CO2 just barely in the water.

Sara did the usual data collection and water samples.
We swapped the 7700 â€“ sn TG1-0224 that had a wash pump problem came off and sn TG1-0155 that just came back from Licor went on. The wash reservoir was about 2/3 empty and was refilled.
Before the swap the 7700 read: 2.25ppm, 50RSSI â€“ after the swap 2.19ppm, 70RSSI

The 7500 read: 17.91mmol/m3 CO2, 528mmol/m3 H2O, 14.2C, 101.8kPa, 247diag

I put up a 2x4 on the west side of the tower and we moved the data logger box 90 degrees to that location. This gave some slack to some cables and made the door opening easier. We also swapped the grounding lug on the bottom of the box and finished up the grounding rod.

I added a railing to the end of the boardwalk to fill in the gap where the tower was before.

I made a mount for the tipping bucket to mount it on the south side at about the midpoint of the boardwalk. Hopefully this will keep the birds off of it and make it easier to check.

The Raspberry Pi camera seems to have failed. It was unresponsive and would not reboot. I brought it in for testing.

I replaced the fan on the HMP60. The new fan is 10mm thick.
