Thompson Cruise Report August 6-7 20:30 local time

We departed Newport at 15:30 Monday. Burke and Lee made it to the ship just in time. Thanks to the people who helped with getting messages through about the delays in traffic due to the accident on Highway 20. Cidney, Paul, Leah, Burke and Lee all had to drive back to Philomath and then take Highway 34 to Walport.

August 6: we complete a test of the profiling pump, collected water for 10 day deck incubation to simulate a phytoplankton bloom, and complete the hydrosweep mapping upstream and around the midshelf mooring (CH-3) on the Cascade Head line (line 2).

August 7: we tested Moum's turbulence profilers and got all the optics and most of the chemistry on line. We completed an inshore pump station at CH-1 (including 14C incubations for 2 depths and respiration at one depth). Surface water is about 12.5 degrees and probably nitrate depleted. Chlorophyll is about 15 ug/L based on calibrations from May. We started the profiling transect at 18:30. With present wind and current conditions we should complete the transect at 01:00 and then do a pump station at CH-6.

Plans for the next few days:
ADCP CH-6 to CH-1, CH-1 to CH-3
Start 48 h times series at CH-3
Repeat sampling transect (CH-1 to CH-6) and pump stations (CH-1 and CH-6) alone CH-line.

I have not been able to connect with Jack yet aboard the WECOMA by cell phone but will keep trying. Most groups have doubled up for the first experiments, but the novices aboard are picking up the routine quickly.
