Summary: Marathon 6400 measurements day 1

Field Notes

Tonzi and Vaira Ranches

I went to Tonzi for the purpose of taking photosynthesis measurements with the LICOR 6400. The days were expected to be a little too cool to see the optimum in Vcmax but I wanted to try anyway. Our latest data were a little noisy and sparse, and I had a new strategy to reduce noise. I marked about 6 large leaves and sampled them repeatedly, giving each leaf a day to recover from time spent in the chamber.

Day 1

On Friday I arrived about noon, snuck in one or two A/Ci curves and set up the tent with Dennis. Took soil moisture measurements at Tonzi. I will put these into the spreadsheet:
