SAMPLES ARE CURRENTLY UNAVAILABLE. Please contact the NEON Biorepository for information about when these samples will become available. This collection contains genetic extracts from homogenized zooplankton samples collected during zooplankton sampling in lakes (NEON sample class: zoo_dnaExtraction_in.dnaSampleID). Zooplankton DNA samples are collected three times per year at lake sites during aquatic biology bout windows, roughly in spring, summer, and fall. Samples are collected using either a tow net (water deeper than 4 m) or a Schindler-Patalas trap (water shallower than 4 m) depending on the depth at the sampling location. Samples are collected near the NEON profiling buoy as well as the inlet and outlet sensor sets. Zooplankton DNA samples are preserved in ethanol in the field. The samples from bout 2 (summer) are shipped to an external facility for homogenization and high-throughput sequencing (metabarcoding). Genetic extracts in 96-well plates are archived in the NEON Biorepository at -80 degrees Celsius. See related links below for protocols and NEON related data products. The metabarcoding analysis protocol used by Jonah Ventures (external facility) is available in the NEON document library (https://data.neonscience.org/documents).
