A new restored tidal freshwater wetland located on the west Delta, within Oakley, CA. The tower is located in the eastern side of the Gilbert Parcel seeing the mid marsh transition zone upwind. Restoration work is done by DWR and started in 2018, revegetation planting started in late 2019, followed by tidal action restoration in October 2021.

| 44 | Chamber fluxes | MB, GT, EL | 2023-12-06 - 2024-08-15 | Twice | CH4, N2O, CO2 chamber fluxes in wetlands | Part of Kuno's global quest to measure as many wetland chamber fluxes as possible. We used homemade dark floating chambers for most of the samples, although we also experimented with homemade clear floating chambers and the Smart Chamber if it was dry enough. We measured water quality parameters (temperature, pH, DO, conductivity, turbidity, ORP, WTD), took 10cm deep soil samples at some points, took dissolved gas samples from the water (December samples only), and recorded each point with GPS. |
| 43 | Chamber fluxes | GT | 2024-09-19 - 2024-10-23 | Weekly | CH4, CO2 chamber fluxes and thermocouple profiles during high/low tide | About 50m west of the tower, we installed three sets of thermocouple profiles (+5cm, 0cm, -2cm, -8cm) with an IRT. Two sets also had a miniDOT. Robert is interested in how these temperatures fluctuate during the tidal cycle in different parts of the wetland. Concurrently, Kuno took CH4 and CO2 fluxes using floating chambers and the LI-7810. He sampled on 6 days. 2024-09-19 – low tide 2024-09-24 – high tide 2024-10-05 – low tide 2024-10-09 – high tide 2024-10-16 – low tide 2024-10-23 – high tide See the field note from 2024-09-19 for more of the set-up details: https://biometlab.cnr.berkeley.edu/biometlab/bmetdata/fieldnotes.php?recno=4586 |
| 48 | Lidar | MB, EE, WP, GT | 2023-03-23 - 2023-03-25 | Once | Drone Lidar and 10-band imagery | On March 23rd to 25th, 2023, eTrac (a Woolpert Company) flew a drone with Lidar and 10 band imagery over Mayberry, East End and West Pond on Twitchell and Gilbert Tract at Dutch Slough. 34 flights at a height of 90m above ground level were flown. The drone was a DJI Matrice 600 Pro octocopter and it carried a Riegl MiniVUX-1 Laser Scanner and an Agrowing Sony Alpha a7R11 10-band camera. The Lidar resulted in 161-184 points per square meter with vertical standard deviation of about 2cm. Point clouds (LAS), Digital Terrain Maps (DTM) and Digital Elevation Maps (DEM) are available. The camera has the following bands: 405, 430, 450, 550, 560, 570, 650, 685, 710 and 850nm. The stitched imagery in geotiff format is available at the 1.5, 3, 15, 30cm and 1 and 3m resolutions. At the 1.5cm resolution there is only the full 10-band image. At the other resolutions RGB, grayscale NDVI and colorized NDVI are also available. The total data size on disk is 1.37TB. The three LAS files are about 5GB each, the stitched imagery is 207GB and the raw images are 1.14TB. |

The drone was a DJI Matrice 600 Pro octocopter and it carried a Riegl MiniVUX-1 Laser Scanner and an Agrowing Sony Alpha a7R11 10-band camera. The Lidar resulted in 184-216 points per square meter with vertical standard deviation of about 2cm. Point clouds (LAS), Digital Terrain Maps (DTM) and Digital Elevation Maps (DEM) are available. The camera has the following bands: 405, 430, 450, 550, 560, 570, 650, 685, 710 and 850nm. The stitched imagery in geotiff format is available at the 1.5, 3, 15, 30cm and 1 and 3m resolutions.

| 46 | Soils | GT | 2022-02-18 - 2022-02-18 | Once | Impounded marsh soil core for charcoal | Ari and Oscar Ticas extracted a 1m peat soil core from an impounded area of Dutch Slough (northern end of Gilbert Tract). The core was sliced vertically into 2 cm samples. 1 cc from each slice was analyzed for dry bulk density, organic matter (loss on ignition method), water content, and charcoal count. This project was for Oscar's senior thesis. |
