Coarse downed wood bulk density sampling (DP1.10014.001)

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. Latency: The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package.
