Summary: Standard data collection, swapped 7550-7500 cable and pressure port gasket.

West Pond 2014-10-16 I arrived about 11:45 with Sara. It was still and warm with high thin clouds. The water level was normal and the inlet was running. We did the standard data collection. The 7500 read: 390ppm CO2, 575mmol/m3 H2O, 90.9SS, 22.7C, 101.2kPa The 7700 read: 2.00ppm CH4, 52.5RSSI – 81.5 after cleaning We swapped the cable between the 7550 box and the 7500A head per Licor’s orders. The GHG readings did not change after the cable swap. There is also a gasket upgrade to the pressure port of the 7550 box that we did. Sara took water samples. The water sensors did not need cleaning.
