Bouldin Alfalfa

Carlos and I arrived at 12:30 PST. It was cold and breezy with a light overcast. The farm equipment that used to be up on the levee has now been moved elsewhere--I guess they're not worried about flooding anymore.

Our alfalfa was very short and sparse. At first I thought sheep had been through again, but looking at the phenocam photos, the alfalfa were actually grazed over multiple days by geese or other water fowl.

I downloaded met, cam, USB GHG, FD, and IRT data. Carlos cleaned flux and rad sensors. There was a decapitated mouse on the rad boom--Carlos gagged a lot and dry heaved into the irrigation ditch. I changed the eddy clock +1:30min from ~12:49 to 12:50:30 and restarted logging. I also checked the phenocam clock and changed it ~1:30min from 12:54 to 12:55:30.

We walked over to check the PL Arable since it might've been damaged again from sheep. There was a dead mouse on the ground next to the post and Carlos cleaned off some blood from the incoming Arable sensors.

The 7500 read: 420ppm CO2, 218mmol/m3 H2O, 13.8C, 101.5kPa, 105SS--106 after cleaning

We left at 13:00 PST.
