description: Benthic microbe samples are collected at the same time and location as periphyton (microalgae) samples three times per year in wadeable streams during aquatic biology bout windows, roughly in spring, summer and fall. Samples are collected using aseptic methods using the most appropriate sampler for the habitat and substratum type, including rock scrubs, grab samples, and epiphyton. Samples are collected in the two most dominant benthic habitat types (e.g. riffles, runs, pools, step pools). Cobble scrubs are filtered on 0.22 um Sterivex capsule filters, capped and flash-frozen in the field. Grab samples of sediment (silt, sand) or plant material/epiphyton are collected when appropriate. All samples are frozen on dry ice in the field and are shipped frozen 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.

title: Groundwater and active layer measurements at permafrost sites (DP1.20099.001)
title: RELEASE-2025

description: In arctic environments with permafrost there is a seasonal change in active thawed layer and liquid water that drive the hydrology of the system. This seasonal freeze/thaw cycle causes frost heaving of groundwater wells, making measurements of groundwater elevation inaccurate due to sensor movement. Therefore, this data product contains measurements of depth to liquid water and thaw relative to the ground surface made manually rather than using a sensor that would require a fixed elevation throughout the season. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.
description: Up to eight shallow groundwater wells per site are installed in inter-tussock areas surrounding the lake and stream reaches to capture groundwater flow paths. Wells are pushed down to thaw depth on a weekly basis and hand measurements are reported for depth to water and depth to thaw relative to the ground surface. Instrumentation:

title: Elevation of groundwater (DP1.20100.001)
title: RELEASE-2025

description: There are important linkages and feedbacks between groundwater and surface water in streams, rivers, and lakes.  NEON measurements of groundwater elevation at high resolution temporal changes informs these linkages. Three to  eight wells are available per aquatic site.  In this way, magnitude and direction of groundwater flow can be calculated.  Wells are located both near the water body and further from the water body to enable investigation of hyporheic groundwater flow paths.  This data product contains continuous, quality-controlled, groundwater depth converted to elevation above mean sea level. Measurements are captured every five minutes and reported as 5-minute instantaneous measurements and 30-minute averages.

title: Fish sequences DNA barcode (DP1.20105.001)
title: RELEASE-2025

description: This data product contains the quality-controlled laboratory metadata and QA results for NEON's cytochrome oxidase I (COI) barcoding of fish sequences. Fin clips are taken from a subset of collected fish for DNA analysis. The DNA barcoding procedure involves the removal of tissue, extracting and sequencing DNA from the tissue, and matching that sequence data to sequences from previously identified voucher specimens. DNA analysis serves a number of purposes, including verification of taxonomy of specimens that do not receive expert identification, clarification of the taxonomy of rare or cryptic species, and characterization of diversity using molecular markers. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. Queries for this data product will return metadata tables formatted for submission to the Barcode of Life Database. These queries will also provide links to the actual sequence data, which are publicly available on the [Barcode of Life Data System](http://www.boldsystems.org/) (BOLD) website. The sequence data can be obtained by following the links from the NEON data portal, or by directly querying NEON data sets on the BOLD server. From the NEON portal, the link "BOLD Project: Fish sequences DNA barcode" redirects to a page on the BOLD public data portal for the queried data. This is a dynamic link and will automatically update based on the user query.
