Mayberry
1/31/2012

I arrived about 9am with Jaclyn and Sara. It was cool and sunny with little to no breeze. There was fog around, but most of Sherman Island seemed clear. The tules and cattails continue to look brown. The ground was damp.

I moved the Setra air pressure sensor from the CR23x to the CR1000 and updated the CR1000’s program after swapping the card. I removed the CR23X and pulled the six remaining thermocouples. The water TCs were deep in the water probably near the bottom and not near the top where they were supposed to be.

The 7700 RSSI was about 78% and the wash reservoir was full.

Sara and Jaclyn collected three tule and three cattail plots for biomass.

I cleaned the radiometers on the Tule Tower. The upward part of the net sensors was pretty dirty from bird feet.

The Tule Tower may have settled a little. The east end was a little deeper in the water than the west end. I kicked the foot adjustment screws on the west end to lower that side a little. The guywires in the middle still seemed taught.

The conductivity sensor is still reading zero. I saved a screen shot of its intermediate values to see if I can puzzle it out.
