Sample Ball Flow = 37. Pump Pressure = 8.9 psi. 9:37:40 Switch to gas A. 9:38:10 Done adjusting regulator to get Flow = 37, Pressure = 8.9 psi. CO2 = 60.40 - 60.44 um/m. H2O = -0.785 um/m. LiCor P = 70.82 kPa 9:40:45 Step 3-way to B. 9:41:00 Adjusted regulator to get Flow = 36.5, Pressure = 8.8 psi. 9:42:30 CO2 = 16.32 - 16.37 um/m. H2O = -0.814 um/m. LiCor P = 70.81 kPa 9:43:45 Step 3-way to C. 9:44:15 Adjusted regulator to Flow = 36.5, Pressure = 8.8 psi. 9:45:30 CO2 = 35.05 - 35.13 um/m. H2O = -0.840 um/m. LiCor P = 70.81 kPa 9:47:15 3-way back to HYDRA, System on D-S3 CU Tower 10:14:16 MDT On level L2. CO2 = 1.317 Switched profile to manual. Toggled C2. 10:14:55 P = 20.8 psig. 10:16:30 3-way to ICS, Cylinder A 10:17:30 Adjust regulator to get 21 psig. 10:18:30 Vco2 = 1.293 10:19:30 Step 4-way to B 10:20:00 Regulator adjusted to get 21.0 psig. 10:21:00 Vco2 = 1.129 10:22:00 Step 4-way to C 10:22:30 Regulator adjusted to get 21.0 psig. 10:23:30 Vco2 = 1.200 10:24:30 Toggled C2. CO2 = 1.258 10:27:00 Back to Auto, sampling L2 10:27:15 Switch to L3, CO2 = 1.296 USGS Tower 9:36:30 MST Sampling line 11, P = 547.63 9:38:30 Switched 3-way to start ICS, Cylinder A 9:40:30 Adjusted regulator to get 546.6. CO2 reading is 393.3 - 393.5. 9:42:30 Step 3-way to B. 9:43:00 Done adjusting regulator to get 546.6. CO2 = 325.91-326.02 9:46:00 Step 3-way to C. 9:46:30 Done adjusting regulator to get 552.28, CO2 = 354.55 - 354.67, H2O = -1.136. 9:49:00 Switched 3-way back to sample from towers, line disconnected. System on line 7 AIRCOA B Aspen site 11:19:45 MDT Rebooted unit 11:21:30 MDT = 17:21:22 UTC 17:21:22 Connect palmtop. Sampling air, Line 0, slow flow. P = 71.471, CO2 = 346.3 - 343.8 After switching to High flow, P = 77.788 17:24:00 Took control. Open V11, V12. Adjust regulator to 10. 17:24:53 Switch to A 17:25:00 P good @ 77.815 17:26:15 V12 turned off. 17:27:30 Tried switching valves on and off repeatedly to get bit 19 to toggle. Toggled it manually. Then remembered that Gordon's new program uses bit 20, which we don't see P = 71.51, CO2 = 392.7 - 393.15 17:29:30 Switch to gas B, V12 on 17:30:30 Close V12 17:30:50 Open V12, adjust P to 73.22 17:32:00 Close V12, P = 71.296, CO2 = 321.5 - 322.3 17:33:00 P = 71.296, CO2 = 321.5 - 322.3 17:34:34 Switch to C, V12 on 17:35:28 V12 off 17:36:15 P = 71.404, CO2 = 350.7 - 352.3 17:38:02 Return unit control to Prometheus HS2 = 1610, HS1 = 1840, LS1 = 1760, LS2 = 1720
