Summary:
At tower, we downloaded ghg, pheno and no met. No pictures after 4/18. We got the 2 miniDot data, 2 headspace samples from the boardwalk near the DO sensors (5cm below surface).
At flux station took 1 DIC, 1 DOC, and 1 headspace sample. Downloaded dissolved methane, Kor (via bluetooth, 5/9-5/22), and the CR6 data.

Description:
- Warm clear skies, sunny mild breeze

Pre clean
1. CO2 -- 430.4 ppm, signal strength 98.8%, H2O 11.4 mmol/mol, pressure 101.3 kPa, Temp 31.04 C
2. CH4 -- 2.02 umol/mol, 51.4% signal strength

Post Clean
1. CO2 -- 99.3% signal strength, 432 ppm
2. CH4 -- 85.7% signal strength, 2.02 umol/mol

- 7700 temp reading about 4 degrees lower than 7500
- reservoir was full
- changed 7700 to summer hours: from 18:00 to 20:00 for start and from 06:00 to 08:00 for stop.
- forgot to set clock at all sites today (Rush, Hill Slough, Gilbert Tract)
- Water level 54cm at 15:49
- at 15:50 halted miniDOT (tower, non-floating), Record at 15:55
- Pheno pictures stopped at 5/18; couldn't check if pheno was working when plugged back in because we didn't have the right adapter
- at 15:59 halted miniDOT (floating), 16:04 Record
- Changed desiccant packs for both miniDOTs
- didn't collect bird data because we didn't have proper adapter
- Took 2 exetainers at end of walkway near DO sensors (5cm below surface) @ 16:13, 16:16

Lateral flux station arrived at 16:28
- used microUSB to connect to data logger
- all sonde data on data logger shows as NaNs and the SOA light was off
- data stopped at 4/27 at 05:30
- pulled instruments at 16:43, started downloading Sonde data
- miniCH4 halt at 17:06, Record at 17:09
- DIC sample at 16:59
