description: Sediment samples are collected from 2 stations at each site: at wadeable streams and non-wadeable (large river) sites are divided in half longitudinally and sediment is collected throughout each half (approx. 500 m reach per station).  In lakes, there are also 2 stations, the first near the buoy (the deep center point in the basin, called ‘c0’ meaning ‘center’), and the second near the near-shore infrastructure (about 1-2 m deep, called ‘in’ meaning ‘in-shore’).  Within each station, sediments are collected and homogenized from depositional zones at both stations 2 times per year during the spring and fall aquatic biological sampling bouts. Homogenized aggregate samples are subsampled and shipped to an external lab for analysis, or to the NEON Biorepository for archiving. Instrumentation:

description: The aquatic stable isotope sampling protocol is completed in conjunction with the water chemistry protocol. Groundwater is sampled twice per year at NEON aquatic sites from permanently installed groundwater wells.  There are up to eight small (2-in diameter) shallow (<100 ft depth) groundwater observation wells at each site, from which a subset of four wells are sampled. The field protocol used by NEON for collecting groundwater chemistry samples follows the general procedure for minimal drawdown sampling detailed by EPA report Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures (Puls and Barcelona, 1996). For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. Instrumentation:

title: Root biomass and chemistry, periodic (DP1.10067.001)
title: RELEASE-2026

description: This data product contains the quality-controlled, native sampling resolution data from NEON's belowground biomass protocol. These data enable estimation of the amount of belowground plant biomass <= 10 mm diameter within the area surrounding the NEON eddy covariance tower. At many sites this will also be the dominant vegetation type(s). Samples are collected once every five years. Whenever possible, NEON uses a 3-inch outside diameter (6.65 cm inside diameter) soil corer for belowground biomass sampling, with samples cored to 30 cm depth in order to be consistent with the sampling depth used for soil biogeochemistry and microbe sampling. All roots are sorted into three size category bins: <1 mm, 1-2 mm, and 2-10 mm. After sorting, root material is dried, weighed, and analyzed, then any excess root material is archived in the NEON Biorepository and available upon request. For additional details, see the user guide, protocols, and science design listed in the Documentation section below. Products resulting from this sampling include root biomass by size class as well as root chemistry and stable isotope ratios. A summary table of analytical lab precision and accuracy is included in the expanded package.

description: Each site is sampled every five years. At each terrestrial NEON site, roots are sampled from base plots (20-30) within the tower airshed (Tower plots). In each Tower plot, one or two clip cells (depending on plot size) are randomly chosen out of the pre-determined clip cell locations for root coring. The same clip cells are also used for annual aboveground Herbaceous Biomass sampling. In 20m x 20m Tower plots, two soil cores are sampled from one clip cell per bout. In 40m x 40m Tower plots soil core sampling occurs in two (out of four) randomly assigned 20m x 20m subplots, and two soil cores are sampled from one clip cell per subplot per bout. A root core is taken to 30 cm maximum depth from both the northern and southern end of the clip cell. Biomass per size category is pooled by clip strip prior to chemistry analyses, and only live or unsorted biomass is analyzed. Carbon and nitrogen concentrations and stable isotopes are measured, but other analyses are possible by requesting access to remaining root material from the NEON Biorepository. Instrumentation:

title: Litterfall and fine woody debris production and chemistry (DP1.10033.001)
title: RELEASE-2026

description: This data product contains the quality-controlled, native sampling resolution data from NEON's Litterfall and fine woody debris sampling. Litter is defined as material that is dropped from the forest canopy and has a butt end diameter <2cm and a length <50 cm; this material is collected in elevated 0.5m2 PVC traps. Fine woody debris is defined as material that is dropped from the forest canopy and has a butt end diameter <2cm and a length >50 cm; this material is collected in ground traps as longer material is not reliably collected by the elevated traps. Following field collection, each sample is sorted by functional group, dried and weighed. After sorting litter by functional group, material from elevated traps from select bouts is sent for chemical analysis, with excess material archived in the NEON Biorepository and available upon request. For additional details, see the user guides, protocols, and science design listed in the Documentation section below. Products resulting from this sampling include mass of litterfall and fine woody debris by functional group as well as litter chemistry and stable isotope ratios. Summary tables of external lab precision and accuracy are included in the expanded package.

description: Each qualifying tower plot in forested ecosystems has 0-2 elevated traps and 1-2 ground traps deployed. Ground traps are sampled annually. Sampling interval of elevated litter traps is variable by dominant overstory vegetation. Deciduous forests are sampled once in the spring then multiple times during fall senescence; evergreen and coniferous forests are sampled year round at monthly intervals. Traps are consistent with those used by the Smithsonian Center for Tropical Forest Science (CTFS). Mass data for each collection event are measured separately for functional groups: Leaves, Needles, Twigs/branches, Woody material, Seeds, Flowers (which includes other non-woody reproductive structures), and Other. Any material that cannot be sorted due to time or resource constraints is categorized as Mixed (unsorted). Once every five years, material from elevated traps from a single collection event are analyzed for carbon and nitrogen concentrations and stable isotopes as well as lignin concentrations. Prior to 2022, only leaf and needle materials were analyzed. Starting in 2022, all functional group material is measured for chemistry, though the non-leaf and needle groups use a pooled site-level sample. Instrumentation:

description: Soil sampling occurs annually at a minimum of one site per domain and once (sites with short growing seasons) to three times per year (sites with longer growing seasons), with collections occurring at every sampled site during the historic peak in vegetation greenness. Three pre-determined, randomly assigned locations are selected for each sampling event within each of 10 plots distributed throughout a site; sampling locations within a plot are not re-sampled. Soil samples are collected to a maximum depth of 30 cm, with organic and mineral soils sampled separately. The same samples are used for measurement of soil physical and chemical properties to maintain temporal and spatial connectivity. Subsamples of homogenized soil (rocks, roots and organic debris removed) from each of the 3 sampling locations are stored in sterile containers, frozen on dry ice in the field and shipped to an analytical facility for DNA sequence analysis using primer sets targeting the small subunit of the ribosomal RNA gene. Sequence data undergo QAQC and are processed bioinformatically using an in-house pipeline to identify unique sequence variants in the data and to taxonomically identify each sequence variant. Sequence variants, or Operational Taxonomic Units (OTUs), have been computed across all samples, enabling the comparison across all sites and collection dates. Instrumentation:
