Site: Sherman Wetland (SW) aka US-Sne
2016-05-24 - 2021-09-02
A new restored wetland on the old Sherman Pasture site. The new tower is about 67m northwest (300deg) of the old tower site (US-Snd). On Jan 30, 2020 a temporary tower was set up in the western portion of Sherman Wetland to capture the more vegetated areas and compare with the main tower.

| 11 | Report | SW | 2017-01-01 | every time processing | fixing nighttime uptake at SW | Sherman wetland (once pasture) was flooded winter 2016, and we sawuptake spikesat night -there wasno vegetation yet. |
| 13 | Report | SW | 2017-06-23 - 2017-08-02 | Once | 7550 configuration file correction –June to August 2017 | From 2017-06-23(DOY 174)to 2017-08-02 (DOY 214) an incorrect 7500 configuration file was running on the tower. We tried to back out the coefficients but could not determine what coefficients the data had been recorded with. We ended up generating a regression with the 30min data from MB and correction the 20Hz data with that regression. |
| 28 | Soils | SW | 2016-01-01 - 2016-05-30 | Once | Sherman Wetland preflood soil sampling | Dennis remembers Tyler Anthony take a whole bunch of samples (including bulk density measurements) right before we set up the tower in May 2016. Not sure where if we have the data or if Tyler has it. |
| 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. |
