Car at Site

~12:40h white truck on site to deliver instruments and move filter sampler.

Heptane vial

Briefly opened a small vial containing heptane at ~11:40 am. The vial was opened inside a duct exhausting to a large charcoal filter to reduce impact as much as possible.

Dry Ice

At 11:00 AM we moved some dry ice from the parking lot to trailer 7 and then we moved about 2/3 of the way back to the parking lot to crush the ice. In the future we will be crushing the dry ice offsite.

Dry ICE

11:30 am 7/20/11: We moved some dry ice around in trailer 7. This will happen regularly to preserve N2O5 calibration samples. If anyone is measuring CO2 and this was detectable, let us know and we will adjust our transfer procedure! Julie Fry / Kyle Zarzana / Bill Dube / Danielle Draper

There were about 5-6 cars driving to/from and parked at the site yesterday. Please try to minimize car traffic beyond the parking area by the porta pot as we are actively sampling. If you do drive to the site please post on this blog so we can track traffic.

Thanks, Amber
