Summary: Fence repaires, download data, replace FWTCs

12:00 Hehn arrives

clear warm & calm

-Fran Vaira here today -cutting and burning dead oak limbs 100 yards from site
-System running
-exclosure fence down and broken in 2 places--only a week pulse being generated and analog meter not reaching full scale deflection
-repair fence, battery voltage at 12.7 but still only a week pulse
-cow appears to have rubbed on most everything only the Fine Wire Thermo Couples (FWTC) on the Surface Renewal Experiment (SRE) were damaged—no chewed wires
-download flux and met data
-replace 1 FTWC on SR experiment
-Soil Heat Flux (SHF) plate on SRE not wired correctly: all leads connected to ground – move red lead to channel DE 4 hi ERROR
-1 FWTC not wired correctly: change From red-hi, purple-ground, shield-lo; To red-hi, purp-lo, shield-ground
-Solar regulator at Vaira indicated a fully charged set of batteries today
-About 15 amp from solar panels at noon today
