This is the AmeriFlux version of the carbon flux data for the site US-PFf NW5 Grass-1 CHEESEHEAD 2019. Site Description - This tower (2m tripod) is located in the northwestern quadrant of the 10 x 10km study domain. It is located in a grassy field. It is ocassionally mowed. It was located near (~200m) several different types of sounding systems.
This is the AmeriFlux version of the carbon flux data for the site US-DS3 Staten Rice 1. Site Description - This tower is located in a rice field in the California Delta on Staten Island. The tower is within a few square kilometers of rice fields that comprise the vast majority of the southwestern portion of Staten Island. This is part of a multi-year, ground-truthing field study under the DOE ARPA-E SMARTFARM project.
This is the AmeriFlux version of the carbon flux data for the site CL-SDF Senda Darwin Forest. Site Description - Located at the Senda Darwin Biological Station, in a old-growth rainforest. Locally named as Nordpatagonian type of forest. The station is 15 km east of Ancud, in the Chiloé Island, close to the Huicha river.
This is the AmeriFlux version of the carbon flux data for the site CL-SDP Senda Darwin Peatland. Site Description - Located at the Senda Darwin Biological Station, in a old-growth rainforest. Locally named "pomponal" from the common name of Sphagnum, is an anthropogenic peatland, formed after the forest is cut or a forest fire. The station is 15 km east of Ancud, in the Chiloé Island, close to the Huicha river.
This is the AmeriFlux version of the carbon flux data for the site US-Cst Crossett Experimental Forest. Site Description - The study takes place in the Crossett Experimental Forest (CEF, 32°2′ N, 91°57′ W), which was established in 1934 with the objective of developing effective management protocols for loblolly and shortleaf pine forests in the Gulf Coastal Plain. Mean annual temperature and precipitation are 17.6 °C and 1,410 mm, respectively. Most of the soils on and near the CEF are silt loams (primarily Glossaquic Fragiudalfs). The tower is situated in the the old-growth pine management sector of the CEF, which emphasizes management for old-growth-like conditions, with the goal of emulating the structural and compositional attributes of historic forests from this region using a combination of timber harvesting, prescribed fire, and other tools. This includes periodic commercial logging of intermediate-sized loblolly pines to support further restoration treatments, such as prescribed fire, hardwood and exotic species competition control, and the increase of plant species more compatible with fire (e.g., shortleaf pine and understory grasses)
This is the AmeriFlux version of the carbon flux data for the site US-Mo2 LTAR CMRB Tucker Prairie (CMRB TP). Site Description - Tucker Prairie is a 59 ha tract of virgin tall grass prairie in Callaway County, Missouri. This tract of land is the largest prairie remnant in mid-Missouri. It has never been plowed
This is the AmeriFlux version of the carbon flux data for the site CA-DSM Delta Salt Marsh. Site Description - This site is a tidal salt marsh on the eastern side of the Boundary Bay Wildlife Management Area (WMA) in Delta, British Columbia, Canada. This area is located on the southern front of the Fraser River. The total area of the Boundary Bay WMA is 11,470 ha, and the eastern part surrounding the flux tower accounts for 39 ha. This area is surrounded by farms and dikes. The Provincial Government purchased this area in 1974 limiting public access and designated it as WMA in 1995. This area has a mixed semidiurnal tidal cycle. The dominant species is Saltgrass (Distichlis spicata) with a canopy height of ~40 cm. The tower is in a high marsh system and was installed to analyze energy, H2O, CO2, and CH4 fluxes on September 3, 2021.
This is the AmeriFlux version of the carbon flux data for the site US-Dmg Dutch Slough Marsh Gilbert Tract. Site Description - 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.
This is the AmeriFlux version of the carbon flux data for the site US-HVs Happy Valley Wet Sedge Tundra. Site Description - This tower is located at Happy Valley.
This is the AmeriFlux version of the carbon flux data for the site CA-BOU Bouleau Peatland. Site Description - This tower is located in a 2.2km2 ombrotrophic peatland covered at 60% by lichen in Northeast Quebec.
This is the AmeriFlux version of the carbon flux data for the site US-CGG Concord Grazed Grassland. Site Description - This tower located on a grazed grassland in Concord, CA. The land is owned by Cal State East Bay and leased to a local rancher. Approximately 60 head of cattle graze the site from December to April.The site is dominated by annual cool season grasses. The soil on the site is described as Altamont Clay.
This is the AmeriFlux version of the carbon flux data for the site US-CLF Cole Farm. Site Description - The Cole Farm catchment (0.65km2) is located ~ 4 km southwest of the Shale Hills site, draining orthogonally to a syncline axis of the Wills Creek Formation, a calcareous shale containing interbedded siltstone, sandstone, shaly limestone, and dolomite. Even though the farm adopted no-till practices in the 1970s, the axial channel of Cole Farm flows over a thick (>2.5 m) package of sediment in the valley floor. Soils range in texture from silty clay at the ridge top to sandy loam in the valley floor. Data was collected and funded by the Critical Zone Observatory Network.
This is the AmeriFlux version of the carbon flux data for the site US-Cms Central Marsh. Site Description - This tower is located near Central Marsh, Barrow. The wet sedge is dominated on permafrost.
