BCSE Series 1 gas sampling - Brian, Slater Hydrosense in LTER and BCSE - Kevin trained Alyssa (MCSE and BCSE) and Stacey (DF) Evacuated LTER lysimeters that were installed in fall 2024 since conditions were very dry many did not yield leachate in November or December 2024. These lysimeters were evacuated on 3/7/2025 and left over the weekend. The lids were completely off from DF3-1 and DF3-6. On 3/11/2025 they were checked for pressure, the volume of leachate approximated and then the leachate dumped before re-evacuating with the regular sampling. - Stacey Lysimeter, pressure, volume from 3/11/2025; CF1-1, N, 0; CF1-3, N, 0; CF1-6, N, 0; CF2-1, N, 20; CF2-3, Y, 300; CF2-6, Y, 200; SF3-1, Y, 600; SF3-3, Y, 450; SF3-6, Y, 200; DF3-1, Y, 350; DF3-3, Y, not recorded; DF3-6, N, not recorded; CF3-1, Y, 50; CF3-3, N, 50; CF3-6, Y, 200 |
