I arrived about 12:30 with Patty and Madeleine. It was clear, sunny and hot with little to no wind. The pepper weed is a sea of white flowers, pollen and fungus dust. It seems the three of us do not have allergies to it.

The LGR read: 12:38, 29.27C, 140.9Torr, 14.77usec, 10Hz, 1.918ppm CH4
I did not adjust the bypass valve.

The 7500 read: 15.8mmol/m3 CO2, 400.0mmol/m2 H2O, 101.87kPa, 33.31C, 249diag

When I swapped the card on the CR1000, I updated the OS from v15 to v27. I had to reload the program, but seemed to go well. The new OS will allow the use of CFM cards up to 16GB.

The new program on the autocam seems to be working properly giving us three raw images at midday and the rest of the normal jpeg images.

The water at the south well was 69cm below the top of the pipe and 109cm at the north well.

Moisture point readings:
East
Rep 1: 13.0, 42.6, 39.6, 11.1 (discard level 3)
Rep 2: 11.8, 42.3, 72.5, 11.1
Rep 3: 10.6, 41.7, 67.8, 11.1
North
Rep 1: 31.1, 41.7, 52.5, 11.1
Rep 2: 32.6, 41.7, 51.6, 11.1

The battery may be loose in the Moisture Point box. Siyan couldnâ€™t get it to work at Tonzi last time and I saw the power flicker when I moved it around.

I did the spectral measurements. Really need to fix the touch pad or get a new netbook. I raised the tripod to its full height (about shoulder high) to take measurements about the pepper weed.

Patty and Madeleine did a LAI, and veg height transect. They also did soil respiration measurements. Patty swapped the 2cm Profile B probe (removed: sn Z2720011; installed: sn F4960019) and the 16cm Profile B probe (removed: sn G0150037; installed: sn G0150035). The lower one had been reporting elevated values and was kind of wet with brown slime.

Veg Height (cm): Tape measure from ground to top of plant - pepperweed dense and blooming
80, 70, 67, 80, 90, 110, 90, 80, 100, 110, 96, 94, 65, 94, 85, 110, 80, 76, 89, 80, avg = 87.3, stdev = 13.57
