| 6 | Lidar | SI, MB, SB | 2007-02-01 | Once | Sherman Island part of DWR Delta wide 2007 Lidar flight | These data are from LIDAR flights of the Sacramento-San Joaquin Delta conducted during late January and February of 2007. The work was conducted under contract issued by California Department of Water Resources to URS Corporation. All data are registered to UTM Zone 10, NAD83, vertical datum NAVD88. The elevation units in the point files are in meters. The elevations for the ESRI grids are in decimeters (done to allow integer type grids to save file size). The bare earth grid is of one meter resolution. The accuracy specifications are as follows: Vertical accuracy: 95% at 0.6’ (<18.5cm) and 90% at 0.5’ (15cm) Horizontal accuracy: 1.0’ (30cm), 1 sigma. |

Horizontal datum: NAD83 (NSRS2007) Epoch 2017.95, UTM Zone 10N, meters. Vertical datum: NAVD88, GEOID12B, US Survey Feet, Orthometric. Includes classified point cloud, features shape files, bare earth DEM, orthometric imagery (0.3-meter16-bit 4-band RGB-IR tiles in TIFF format with World Files). The entire Delta is covered by 8 points per m2, 0.5m DEM. |

| 30 | Soils | SB, BC, Bouldin 1, Staten | 2016-08-01 - 2018-03-15 | Once | %C, %N sampled by Tyler Anthony | Tyler Anthony (Whendee Silver's lab) analyzed %C and %N from shallow soils: -Sherman Barn (Tyler refers to it as "Sherman Pasture"), 0-10cm, probably sampled in Spring 2018 -Bouldin Corn, 0-15cm, sampled 2017-05-16 -Bouldin 1 (Tyler's alfalfa auto-chamber site by the barn), 0-15cm?, sampled 2016-08-01 -Staten ("taken from a corn field west of the road), 0-10cm, sampled 2018-03-15 |
| 25 | Soils | SB, BC, EP, EE, BA, SW, MB | 2018-08-27 - 2018-08-28 | Once | Soil cores for C:N and microbial community | Soil samples were collected to be analyzed for soil moisture, bulk density, C:N, and microbial community. Generally at each site, two transects were sampled (T1 to the north, T2 south), starting near the tower and going to the west. Each transect had 5 sampling locations each (P1-P5), each location about 5m apart. At wetland locations (SW, MB, EE, EP, WP), soils were collected at 0-15cm depth. At agricultural locations (BA, BC, SB), soils were collected at 3 depths: 0-15cm, 15-30cm, and 30-60cm. For more information, see the field notes from each day. 2018-08-27 -Sherman Barn: The water table was around 50-60cm. -Bouldin Corn: Transects starting from the first corn rows running parallel away from the tower. Dry peat layer around 60 cm. -Bouldin Alfalfa: Transects starting roughly 5m from the tower. A smaller subsample was taken for microbial analysis. -East End: Transects starting 5-10m from the tower, going west/southwest through dense veg with the T2P4 and T2P5 taken from veg near the open water section. A smaller subsample was taken for microbial analysis. -East Pond: Transects starting about 7m from tower to the west (T1) and southwest (T2). (i.e. after the big open pond section by the solar panels). A smaller subsample was taken for microbial analysis. T2P5 was taken from the more uniformly vegetated area to the west. Other samples were mostly from fairly open water areas near clusters of veg. 2018-08-28 -Mayberry: Two transects (T1 in veg, T2 near the open water) each going northwest of the tower and took microbial subsamples from each core. -Sherman Wetland: We took two transects (T1 to the north, T2 south) going west from the tower starting where the water was about 20 cm deep and following the low vegetation. |
