45 | Porewater | HS | 2022-07-13 - Present | Approx. bi-weekly with field visit | Hill Slough porewater | A porewater sipper was installed underneath the Hill Slough tower on 2022-07-13. Ari thinks the depth is 10cm. Water is sampled by syringe with every site visit. We usually discard the first 10ml withdrawn from the sipper to flush out any standing water in the sipper. No data March-July 2023 because we were waiting for our own handheld conductivity meter to arrive. |
38 | Soils | HS | 2021-07-07 - 2021-07-08 | Once | Preflood base line sampling | 2021-07-07 to 2021-07-08. Soil cores were collected from nine locations at Hill Slough. At each location, three short cores (up to 30 cm) and one long core (up to 60-99 cm) were collected. Two of the short cores were cut into approximately 2.5 cm sections, and one at 1 cm thick intervals in the lab. Long cores were sliced at 5 cm intervals in the field. Soil samples were analyzed for delta13C, delta15N, C, N, and organic matter content. Additionally, at locations 1, 2, and 4, soils were analyzed for Pb-210. Scott Jones from USGS conducted vegetation and RTK-GPS (Real Time Kinematics with centimeter resolution) measurements for the sample locations and additional points in between sample locations on 2021-07-20. Regarding the post-fixes on the sample names: N denotes North, E = East, S = South, and L = Long. The long core at each plot was collected at the center of the triangle formed by N, E, and S (with approximately 2 meters distance between cores). Due to a shortage of acrylic short tubes, from site 5 to 9, we collected N, E, and L cores. |
40 | Soils | HS | 2024-06-12 - 2024-06-26 | Once | Postflood sampling | Soil cores were collected from eight locations at Hill Slough, redoing the same locations as preflood sampling in 2021. HSM_1, 2, 3, 4, 6, 7, 8, 9 were sampled. We skipped HSM_5 because it was mostly levee construction soil, not wetland soil. At each location, three short cores (up to 30 cm) were collected. Two of the short cores were cut into approximately 2.5 cm sections, and one at 1 cm thick intervals in the lab. Soil samples will be analyzed for delta13C, delta15N, C, N, and organic matter content. Some soils will also be analyzed for Pb-210. |
