This is the AmeriFlux version of the carbon flux data for the site US-CS4 Central Sands Irrigated Agricultural Field. Site Description - Heartland Farms Center-Pivot Irrigated Potato Field
This is the AmeriFlux version of the carbon flux data for the site US-BZF Bonanza Creek Rich Fen. Site Description - The rich fen is in the boreal peatland lowlands of the Tanana Flats in interior Alaska. Lacks near-surface permafrost even though the surrounding landscape is marked by the presence of permafrost. Peat depth is 1-2m. Primary wind direction in the summer is WSW.
This is the AmeriFlux version of the carbon flux data for the site US-BZS Bonanza Creek Black Spruce. Site Description - Mature black spruce boreal forest with cold, permafrost soils on a peat plateau. In the Tanana lowlands in interior Alaska. Primary wind direction in the summer is WSW.
This is the AmeriFlux version of the carbon flux data for the site US-KS4 Kennedy Space Center (Spartina marsh). Site Description - Salt marsh dominated by Spartina bakeri
This is the AmeriFlux version of the carbon flux data for the site US-MBP Marcell Bog Lake Peatland. Site Description - The study site is a fen within the Marcell Experimental Forest, which has been monitored for fluxes and environmental variables at various points in time. In 2007 an EC tower was established to monitor CO2/H2O fluxes within the peatland. Methane observations were added in 2009 and have been ongoing since. This site has also been referred to as Bog Lake Fen in the past.
This is the AmeriFlux version of the carbon flux data for the site US-LL1 Longleaf Pine - Baker (Mesic site). Site Description - Mesic longleaf pine site with wiregrass in the understory and >90 year old Pinus palustris in the mid- and overstory
This is the AmeriFlux version of the carbon flux data for the site US-LL2 Longleaf Pine - Dubignion (Intermediate site). Site Description - Intermediate longeaf pine site with wiregrass in the understory and >90 year old Pinus palustris and Quercus spp. in the mid- and overstory and Quercus spp.
This is the AmeriFlux version of the carbon flux data for the site US-LL3 Longleaf Pine - Red Dirt (Xeric site). Site Description - Xeric longeaf pine site with wiregrass in the understory and >90 year old Pinus palustris and Quercus spp. in the mid- and overstory
This is the AmeriFlux version of the carbon flux data for the site US-xLE NEON Lenoir Landing (LENO). Site Description - This terrestrial field site is located in a hardwood bottomland with seasonal flooding each spring located in southwest Alabama. The meteorological/flux tower and tower sampling plots are located at Lenoir Landing and the distributed plots are located approximately 5 km south of the tower at Choctaw National Wildlife Refuge. The ecosystem at LENO is dominated by closed-canopy pine-oak mixed forest with a developed understory, and also includes a small fraction of meadows, wetlands, and smaller water bodies. Dominant plant species include American sweetgum (Liquidambar styraciflua), American hornbeam (Carpinus caroliniana), and loblolly pine (Pinus taeda). Choctaw National Wildlife Refuge also provides a protected wintering area for waterfowl and wood duck brood habitat. This site is colocated with the Lower Tombigbee river aquatic site.
This is the AmeriFlux version of the carbon flux data for the site US-xPU NEON Pu'u Maka'ala Natural Area Reserve (PUUM). Site Description - NEON's PUUM field site is located in the Pu'u Maka'ala Natural Area Reserve (NAR) on the eastern side of Hawaii’s “Big Island,” managed by the Hawaii Division of Forestry and Wildlife (DOFAW). More than 18,000 acres in size, the NAR is home to a rainforest with many native species, some of them endangered. It was established to protect some of the Big Island’s best wet native forest and unique geologic features.
This is the AmeriFlux version of the carbon flux data for the site US-xRN NEON Oak Ridge National Lab (ORNL). Site Description - Oak Ridge National Laboratory (ORNL) is located at the U.S. Department of Energy's Oak Ridge Reservation in Roane County, Tennessee. The ORNL reservation is situated within the borders of five parallel ridges and valleys to the north of the Clinch River that are part of the Ridge-and-Valley Appalachians physiographic province (Environmental Sciences Division n.d.). The NEON tower site and Walker Branch aquatic site at ORNL are located within the Walker Branch Watershed, a 100 ha area that has served as the site for long-term environmental studies by the Environmental Sciences Division at ORNL, NOAA, and many visiting university researchers.
This is the AmeriFlux version of the carbon flux data for the site US-BZB Bonanza Creek Thermokarst Bog. Site Description - Intermediate to old age thermokarst collapse scar boreal bog in the Tanana Lowlands of Interior Alaska. Peat soils ~1-m thick. Recharged by precipitation and runoff from the surrounding forested peat plateaus. Primary wind direction in the summer is WSW.
