- Sediment sample mid-river during measurement
For the mid river sampling, you should use a plastic bottle and get a grab sample during the discharge measurement (i.e., just one sample per day). Just put the bottle as deep as you can (with your hands) and collect the water. Please write the time.
- Set up Cataraft
- pound in screed stakes / rebar
- water level measurement
- Setup isco:
I believe you guys will focus your activities near the crossing. I suggest to put the ISCO there too. You should try to fix the end of the tube (where the water enters the tube) to a rebar. The rebar could be near the bank (as long as it is located in moving waters). We don't want to capture any bed sediment. Any distance above 30 cm from the bottom (river bed) and 20 cm below the top (water surface) would work. Set the sampler to take 4 samples per day. You should collect samples at 3 AM, 9AM, 3 PM and 9 PM (four in a day).
Tools
- Bob's toolbags (in helicopter)
- Dry suits & boots
- cordless drill
- unbroken survey rod & tripod
- survey tripod at Kanex or in Lab4
- sledge (in helicopter)
Things to do yet in Toolik
- Follow up on Ken's email about other station work
- Continue Daily Computer Backups
- Umiat Send list:
- Trimble Setup
- Trimble Tripod
- 50W solar panel
- unistrut
- quarter inch bolts (short)
- Staff gauges
