  1. LISST-SL Field Testing inWestern Washington Chris Curran, Jon Czuba, and Raegan Huffman USGS-Sequoia WebEx Workshop January 30, 2012

  2. Field Testing Field testing has occurred in western Washington since the LISST-SL was purchased in 2009.

  3. Swimming issue (needs more weight)

  4. LISST-SL Testing Plan Perform testing on three rivers Side-by-side comp. w/ FISP samplers EDI method for stationing ADCP for Q-meas. & velocity verifcation Point samples at 0.2, 0.6, 0.8 (P61) Depth-Integrated samples (D74) Aproximately 15-20 samples per site Samples analyzed for SSC and %fines

  5. SSC P61vs LISST

  6. Concentration, in mg/l ??? fine Particle Size Class coarse

  7. Lessons so far… Temperature sensitive instrument DON’T TOUCH BOTTOM of the river bed Need more weight on sampler Sequoia has been a good partner. New tail, new filter, new bleed port, etc.. Sensitive instrument – “temperamental” Requires sig. prep/post time in lab Some inconsistencies exist in units
