Collected intact soil cores in all sites.

Pulled out old buried bags in the sites and buried new soil bags in RWG, RWB, RCG and RCF.

Conducted inorganic-N extractoion experiment.

Gas sampling and changed a sensor in RCF

March 22, 2007

Collected gas samples in all sites.

Changed soil temperature sensor in the crop field.

The soil temperature sensor is needed to repair (the sensor is detecting wrong temperature).

Gas sampling

Feb. 27, 2007

Gas sampling all sites.

* All sites were covered by snow.

* LWG site: skipped no.2 and no.4 points samplings owing to lack of gas chambers

* RCF site: snow was covered, however, soil under snow was thawed (see below the third figure)

Gas sampling on snow surface and anchors

Feb. 20, 2007

Collected gas samples in all sites (sampling on snow surface; on anchors).

Snow is melting and soil is thawing.

Found available sites for harvesting study; 1 plot beside LWB and 2 plots beside JWG.

Changed a rain guage data logger etc.

December 29, 2006

Changed the data logger of rain guage in Ron Risdal site.



Downloaded data from RWB, RWG, RCG and RCF.

Soil temperature sensor of RCF is needed to be changed.
