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 ocurring 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 three sampling locations are stored in sterile containers, frozen on dry ice in the field and shipped to an analytical facility for DNA extraction, sample preparation and high-throughput sequence analysis using primer sets targeting the small subunit of the ribosomal RNA gene operon. Laboratory metadata are passed through the NEON automated ingest process for QC testing and are published on the NEON data portal. DNA sequence data undergo QC testing and unique URLs are generated to enable data download. Instrumentation:

description: 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 metagenomics sampling occurs annually during the historic peak in vegetation greenness. Soil samples are collected to a maximum depth of 30 cm, with organic and mineral soils sampled separately. Subsamples of homogenized soil (rocks, roots and organic debris removed) from each of the 3 sampling locations are combined to form a plot-level composite sample that is used for metagenomics analysis. Samples are frozen on dry ice and shipped to an analytical facility for DNA extraction, sample preparation and shotgun metagenomic sequencing. Laboratory metadata are then delivered to NEON for QC testing and acceptance, and then are formatted for upload to public sequence repositories. Instrumentation:

title: Soil temperature (DP1.00041.001)
title: RELEASE-2024

description: Soil temperature is measured at various depths below the soil surface from approximately 2 cm down to 200 cm at non-permafrost sites (down to 300 cm at Alaskan sites). Soil temperature influences the rate of biogeochemical cycling, decomposition, and root and soil biota activity. In addition, soil temperature can impact the hydrologic cycle since it controls whether soil water is in a liquid or solid state. Measurements are made in vertical profiles consisting of up to nine depths in all five instrumented soil plots at each terrestrial site, and presented as 1-minute and 30-minute averages.

Latency:
Data collected in any given month are published during the second full week of the following month.

This data product is not currently available at the PUUM site (Hawaii) due to the initial soil characterization indicating the soil was too shallow to allow the standard sensor to be installed. An alternative sensor was installed, but it is not currently compatible with the data processing pipeline. Future upgrades to the data processing pipeline will allow the data product to be produced, including retroactively, but this is not expected to occur soon. In the interim, raw sensor data are available upon request via the NEON Contact Form, but have not undergone any quality control, quality assurance, or data flagging.

At four Alaskan sites (HEAL, BONA, TOOL, and BARR) the sensors experience frost heaving which regularly changes the measurement depths. New measurement depths are recorded when technician time and other priorities allow and depths are updated, but sensor depths may change between remeasuring events. In addition, the soil plots at HEAL have been subsiding faster than the surrounding area which may alter their representativeness of the overall site.
description: When possible the soil plots were arranged in a transect with the first plot approximately 15-40 m from the tower in the expected dominant airshed. The middle of airshed was used as the transect vector and plot spacing was based on the distance required for surface soil temperature and moisture measurements to be spatially independent at the 1 hectare scale during site characterization (capped at approximately 40 m due to logistical constraints). Soil plots were microsited as necessary to avoid obstacles (e.g., boulders, streams, and paths) and more compact plot layouts were used at small sites. Soil temperature is measured at up to nine depths within each plot, with the mid-point of the shallowest sensors at approximately 2, 6, 16, and 26 cm. Depths for deeper sensors vary among sites and are based on megapit soil horizon data (NEON.DP1.00097) and depth to restrictive feature (see NEON.DOC.003146).

title: Soil water content and water salinity (DP1.00094.001)
title: RELEASE-2024

description: Soil volumetric water content and an index of soil water ion content (salinity) are measured at various depths below the soil surface from approximately 6 cm down to 200 cm at non-permafrost sites (down to 300 cm at Alaskan sites). Soil moisture is an important component of the hydrologic cycle and is the dominant source of water for most plants and soil organisms making it a key indicator of drought. In addition, soil moisture status influences the severity of flooding and temperature extremes, as well as physical, chemical and biological processes in the soil. Measurements are made in vertical profiles consisting of up to eight depths in all five instrumented soil plots at each terrestrial site, and presented as 1-minute and 30-minute averages. Soil moisture sensors cannot accurately measure frozen water, therefore soil water content values will be absent or flagged if the soil was frozen or corresponding soil temperature data were not available to perform this test.

Latency:
Data collected in any given month are published during the second full week of the following month.

title: Specific conductivity in groundwater (DP1.20015.001)
title: RELEASE-2024

description: Specific conductance is a proxy for the level of total dissolved solids of the groundwater as well as related to the redox potential. Conductivity may also be used as a tracer of distinct water masses for understanding flow. NEON measures of groundwater conductivity at high temporal resolution. Up to eight wells (and as low as three) are available per aquatic site. From NEON groundwater elevation measurements, the magnitude and direction of groundwater flow can be calculated, which may be coupled to better understand the exchange between groundwater and surface water. This data product includes continuous quality-controlled groundwater temperature captured every 5 minutes and reported as 5-minute instantaneous measurements and 30-minute averages.
