<div>==Overview==<br />
In 2011 Jessie Cable and Bob Bolton were awarded an epscor grant to do a project out at CPCRW looking at soil moisture and plant ecology during snow melt (or that is the gist I think).<br />
==Field Visits==<br />
4/7 -- Bob & Bob take out two tripods<br/><br />
4/11 -- Bob & Bob take out the other two tripods<br/><br />
[[BJ CPCRW 4/12 Trip]] -- Start installing sites<br/><br />
[[BJ CPCRW 4/20 Trip]] -- Precip Buckets, AT/RH, Snow surveys, Discharge<br/><br />
<br />
==Equipment / System Component Shopping==<br />
[[JB March 2011 Shopping List 1]] -- Tripod Hardware Round 1<br />
<br />
[[JB March 2011 Shopping List 2]] -- Tripod Hardware Round 2<br />
<br />
[[JB March 2011 Shopping List 3]] -- Electrical<br />
<br />
TBD: Solar Panel to Actionpacker lids connection<br />
== Site Design & Manufacture ==<br />
[[Tripod setup]]<br><br />
[[Inside Box]]<br><br />
[[Data logger Wiring]]<br><br />
<br />
==Instrumentation Metadata (a start)==<br />
Data logger is a Campbell Scientific CR800<br />
Data logger timezone is ''GMT'' (Bob Busey's preference, somewhat negotiable)<br />
AT/RH -- Once per minute; Output 1/30 minutes<br />
Soil Moisture -- Once per 5 minutes; Output 1/30 minutes<br />
Soil Temperature -- Once per 5 minutes; Output 1/30 minutes<br />
Precip -- Totalized 30 Minutes ''Collect every tip, too?''<br />
SapFlow -- ''30 Minutes''<br />
[[Odds & Ends]]<br />
<br />
==Instructions for Salt Slug Solution/Q measurements (a start)==<br />
Water is able to dissolve ~350 g NaCl/liter H2O @ 25C, we went for about 200 g/l solution.<br />
<br />
Using 18 liter container, means adding 3.6 kg salt<br />
# Add H2O up to 12 liter mark<br />
# Start magnetic stir thing<br />
# Slowly add 2 kg salt to water. Be careful not to add too much at one time as it is possible to bury the stirrer. <br />
# Add water to 18 L mark<br />
# Add remaining 1.6 kg salt to the soup<br />
## --> the process up to this point took me about 3 hours. Plan accordingly<br />
# Continue stirring for a number of hours to ensure well mixed solution.<br />
# Dilution process takes place the following days (to be continued).<br />
