title: Mosquitoes sampled from CO2 traps (DP1.10043.001)
title: RELEASE-2021

description: This data product contains the quality-controlled, native sampling resolution data from NEON's mosquito sampling protocol. Mosquito abundance and diversity are sampled at regular intervals by NEON field technicians at all terrestrial sites. For additional details on protocol, see the TOS Protocol and Procedure: Mosquito Sampling. Following collection, all samples are sent to a professional taxonomist who determines the species composition and sex of mosquitoes from a representative subsample. Identified mosquitoes are then processed for pathogen analysis or preserved for final archiving. Products resulting from this sampling and processing include: records of when mosquitoes were sampled, taxonomic and abundance data for a subset of mosquitoes captured, and information about the material archived from the sample. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

description: Benthic macroinvertebrate metabarcodingsamples are collected three times per year at wadeable stream, river, and lake sites during aquatic biology bout windows, roughly in spring, summer, and fall, at the same time and location as morphological taxonomy samples. Samples are collected using the most appropriate sampler for the habitat type, including Surber, Hess, hand corer, modified kicknet, D-frame sweep, and petite ponar samplers. In wadeable streams, samples are collected in the most dominant habitat type (e.g. riffles, runs, pools, step pools). In lakes and rivers, samples are collected in littoral areas using a D-frame sweep. Samples collected during the mid-summer sampling bout (Bout 2) are sent to an external facility for homogenization and high-throughput sequencing. Samples collected during the spring and fall (Bout 1 and Bout 3) are preserved in ethanol and shipped to the NEON Biorepository for archiving.

description: This data product contains the quality-controlled, native sampling resolution data from NEON's Depth profile at specific depths data collection. Depth profile data are collected along with any other sampling protocol in the water column (e.g., phytoplankton, zooplankton, or surface water chemistry). Depth profile data include water temperature, conductivity, and dissolved oxygen data collected every 0.5 m through the water column using a handheld probe. Depth profile data are only collected at the deepest location of the lake near the buoy, or near the river buoy. These data not only provide metadata to accompany the sampling modules, but also inform sampling depths based the thermocline, if present, for water chemistry and associated analytes, surface water microbes, and phytoplankton sampling. Depth profiles are collected year-round, including under ice at northern sites, a minimum of 12 times per year. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

title: Coarse downed wood bulk density sampling (DP1.10014.001)
title: RELEASE-2021

description: The Coarse Downed Wood bulk density sampling data product contains the quality-controlled, native sampling resolution volume, mass and calculated bulk density data from cross-sectional disks cut from downed logs at each of NEON's terrestrial sites at which qualifying logs are present. Disks are preferentially collected from logs that fall into the most abundant 'decayClass x sizeCategory x taxonID' combinations, as informed by the Coarse Downed Wood survey data product. In addition to bulk density from each collected disk, log-level decay, size category and taxonID information is also recorded for each log from which disks are sampled. Data are reported per disk per log, and when multiple disks are collected from the same log, multiple records will exist in the data. Logs are typically associated with a plotID, and disks may also be collected from logs that fall outside of NEON plots. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

cdw_densitydisk:  105

cdw_densitylog:  105
description: Coarse Downed Wood bulk density samples are collected from terrestrial sites with qualifying logs where repeat CDW Survey sampling is performed. CDW Bulk Density sampling is implemented twice per site, the first time within the first three years of data collection at a site, and the second time 5-6 years after the first sampling event. When possible, the same logs are targeted for sampling at both sampling time points. Sampling may occur in up to 20 Distributed Plots and all Tower Plots, and unlike all other NEON TOS sampling, collection of disks may also occur outside of NEON plot boundaries, due to the sparsely distributed nature of target logs. Logs sampled for bulk density are parsed into five decay categories that broadly match existing USFS definitions, three size categories (2-5 cm, 5-10 cm, and greater than 10 cm diameter), and are identified to the highest taxonomic resolution possible according to the USDA Plants database. The bulk density sampling effort is inherently variable from site to site, as it is driven by the number of 'decayClass x sizeCategory x taxonID' (DST) combinations, which is strongly dependent on site-level tree diversity. For each site, sampling is considered complete once all rank-ordered DSTs that cumulatively make up 80% of the total tallies have been sampled. Target disk sample size per DST is n=10 for DSTs >= 10 cm diameter, and n=5 for DSTs < 10 cm diameter.

title: Fish sequences DNA barcode (DP1.20105.001)
title: RELEASE-2021

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 Datasystem (BOLD, http://www.barcodinglife.com/). 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.
