Cleaned flumes out today. No water collected. Some animal feces/urine found in ASP1F1. BAU1F1 and ASP1F1 corn showed obvious flow. Evidence being sediment rills in the flume itself.

Samples were collected on 8/4/26 by Brook and Stacey from BAU1F1, BAU2F1, ASP1F1.

DW brought three samples to campus today (above). About 200-300mls each.

We need an SOP for this.

Again changed the tower 1 IRGASON out after Moriz (JC lab) recalibrated. Water density jumped by 5 g/m3. Seems like a lot.

About 10:45 AM today.

Tower 1, 6'8" from ground, 5' from crop. changed irgason from 1370 to SN 1375.

There may be continued issues with the 1375 IRGASON.

Changed IRGASON because last one was not reading correctly, improper calibration. Swapped around 130 and returned to Moriz with Jiquans lab. They used an empty cylinder to calibrate.

BAU Tower 2 (soybeans) raised to 7ft. Soybeans at tower are at a height of 2 ft. Original tower height was 6 ft. Raised to 7 ft. to be 5 ft above canopy, which is approximately 1.5m difference (between tower sensors and top of canopy).

GC run on Dawn GC: LTAR, Series 19, 07/23/2026. Two vials submitted out of order - 40 before 39. These were switched to proper order on the GC rack and all vials run sequentially. In addition, there was an issue with LTAR Series 18 being stuck on "acquiring" at the very last standard in it's sequence. This caused an issue with loading the Series 19 run, until the Series 18 was aborted for the last standard, and the run cleared from the Run Queue. I think everything worked out, but there may be no data for that last standard on series 18.

Start BCSE G4,5,7,9,10 species composition transects. Three NS transects per plot, main only. Each transect ~2m west of the station flags and numbered 1-3 based on the station number. Stop about every 1m to identify and measure first intercepted plant. - Alyssa, Glori, Jordyn PM
