Tasks

Toolik Prep

• bring out bubble level for surveying again
• get survey gear from Joel (re: our broken rod)
• solar panel for base gps
• Even more AA batteries for ADCP / boat gps
• bring out cataraft pipe for Achilles mount.

Itkillik Station

• water level survey (morning & night)
• Snow Survey
  • Everything is on site
• GPS Survey GPS Master #1 Rebar #1 (& identify it with spray paint maybe?)

Itkillik River Crossing

• Standard aerial pictures @ Bridge crossing
  • Digital Camera
• Plant Cam Setup
• ADCP Measurement
  • 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 Achilles
• pound in screed stakes / rebar
• water level measurement
• Setup isco (After ice goes out):

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).
