Summary: Regular data collection/cleaning, no photos since 4/10--fixed, green reeds around edges of open water areas and channels

Mayberry

I arrived at 16:35 PDT. It was sunny and windy. The wetland is mostly brown still but the edges of channels and open water areas have a distinct green border of fresh growth. This was the first site visit in a month because I didnâ€™t get to Sherman Island 2 weeks ago. The staff gauge read 36cm.

I downloaded met, camera, USB GHG, and miniDOT data. I downloaded the FD data and cleared its memory. The eosGP sensor I installed last month seems to be fine. The HMP45 had some low values in December but the data since then seems fine.

The camera card was out of space because it overflowed and started taking photos multiple times a minute starting 4/10. This is a known problem when we donâ€™t restart the Autocam program about every 25 days.

I scrubbed the staff gauge and changed the minidot and water level sensor desiccants. I cleaned flux and rad sensors. The Rnet sensor over the water had a lot of bird poop on its upward surface. The wash reservoir was 1/3 empty; I refilled it.

LI-7500 readings:
CO2 404ppm
H2O 354ppm
T 21.8C
P 101.3kPa
SS 96-->98 after cleaning
LI7700 readings:
CH4 1.95ppm
RSSI 61--> 83 after cleaning

I left at 17:10 PDT.
