2017-04-05

I arrived about 12:00 with Siyan. I was sunny and warm. Everything is very green but the trees are not as fully leafed out here as at Vaira. There is no standing water in the road.

The Tower computer clock and most of the data loggers are one day ahead. This resulted from resetting the clocks last time. A combination of resetting to DST, then 12 hours ahead due to AM/PM confusion, then having the day advance before finally setting the time back 12 hours, but not fixing the day. At 11:02 I changed the date from 04/06 to 04/05. This affected tz6_tmet, tz5_sm and fmet, tt_CR1000, tf_CR1000.

I collected all the soil CO2 data manually with the laptop because I missed some of it last time.

I removed Yourgryelâ€™s LED sensor (sn RYU-01) and replaced it with one of ours. His had eight channels ( including blue and green) but ours only has four. I did not change the program so four of the channels are garbage.

The hoisting rope had been chewed (maybe by rats) near the hook end. I cut off about 10ft and reattached the hook.

Just before leaving the Tower computer blew up. It got almost too hot to touch. I pulled it out and let it cool down then tried plugging it back in. Nothing. I brought it in. The only things that will not get recorded are the camera images.

Siyan did midday water potential.

The Global Water well loggerâ€™s cable is crumbling.
