I arrived about 9:00 with Sara and Silvano. It was clear and sunny though there was some fog in other areas. It was cold with just a little breeze. The water level in the fields has not changed much. There was a bunch of coots but not many other birds.

All was running when we arrived. Looks like Jim may have run a new power line from the generator as the old spliced one may have be causing the GFI to trip. The LGR read

9:12PST, 32.39C, 71.31Torr, 14.049usec, 10Hz, 2.167ppm

The pressure was low but the external 2um filter was clear and removing it didn't improve the pressure. Next time we need to run the LGR in low flow to see if the blockage is internal. I adjusted the bypass valve to bring the pressure back up to 145.94Torr. There was some condensation in the line just upstream from the external 2um filter but no other water visible.

The serial line for the CR1000 was locked up. Reseating the USB adapter fixed this.

We collected data and swapped cards.
