Site: Hill Slough (HS) aka US-Hsm
2021-03-11 - Present
The site is currently a diked marsh - upland ecotone located at the northern Suisun Marsh. It will undergo tidal restoration in Fall 2021. Restoration work is done by Ducks Unlimited Inc. and will cover an area of 649 acres. After levee breaches, the site tower will be in a high marsh system. Water level at high tide is estimated to be 0.5-1 m above the soil. Ducks Unlimited, Inc. and the Berkeley Biometeorology lab are working together to evaluate the effects of the proposed tidal marsh restoration project.

| 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. |
