Summary: The trees have leaves, soil cores for Ameriflux, Standard data collection, all seems well.

Daphne and I arrived at about 11:50 leaving Berkeley after the lab meeting. It was sunny, warm and green – the trees have leaves but some are only maybe half-way to full. Much dryer than I expected – the puddles on the road are gone and most of the road surface is dry soil. The grass and flowers have begun to grow and I should start veg height next time.

We took soil cores for the Ameriflux soil project today. We dug four pits south, east, north and west of the tower enclosure. It was tough digging even though the soil was still damp. The required 0 and 10cm samples were easy but the deepest sample that was supposed to be at >50cm ended up 20 to 40cm deep and then tended to have a lot of decomposing rock in it.

Around 13:40 Daphne collected the met, flux, FD and camera data. No problems reported. She reset the eddy clock +1min and synced the FD clocks.
The 7500 read: 427.0ppm CO2, 368.0mmol/m3 H2O, 21.5C, 99.3kPa, 100.9SS

I measured the well depth against the wishes of some ants.

We left at about 14:00.

We stopped by around 17:45 to take a photo of the 7550 for AMP inventory purposes.
