Summary: Downloaded data from LGR. Reduced cal gas to 1x per day. Put wood in cubby area to dissuade otters.

Patty arrived 10:15am. Lots of otter poop, some very fresh
CO2=435.82
D13C=-14.5
D18O=-81.19
H2O=254.7
T=44.8
P=119.77
laser Response=12.84

Pressure on CO2 tank=300 psi--really need to swap out within next month. For now Iâ€™ll reduce the # of cal per day; right now running 2x per day, will reduce to 1x per day.
Current program:
Tower 9725 sec
1.5m 500 s
3m 500 s
-runs 3 hrs 4x before running ref gas
Ref gas 300 s

Now Iâ€™ll run the unknown gas sequence 7x before running ref gas
New sequence:
Tower 9725 sec
1.5m 1000 s
3m 1000 s
-runs 3.25 hrs 7x before running ref gas
Ref gas 300 s
*also increased time sampling from profile to improve quality of keeling plots

Re-loaded program, starting with ref gas signal at 10:39am

Replaced all filters, had to clean out a bug on 3m inlet
