2025 Data Release: Zooplankton collection count data recalculated for discrete time periods
March 18, 2025
A subset of zooplankton count data were reported with no or incorrect count data in the Zooplankton collection data product (DP1.20219.001) for all 7 NEON lake sites.
The field adjCountPerBottle in the zoo_taxonomyProcessed and zoo_taxonomyRaw tables was 1) reported as NA for collectDates from 2015-05-12 to 2016-11-01 for the BARC, CRAM, PRLA, and SUGG sites as a result of missing zooSubsampleVolume data, and 2) calculated incorrectly for collectDates from 2021-07-29 to 2023-09-08 due to incorrectly reported zooSubsampleVolume in the zoo_perSample, zoo_taxonomyProcessed and zoo_taxonomyRaw tables for all 7 NEON lake sites. In the 2025 Data Release, the field dilutionFactor is added to the zoo_perSample as a QC field, and concentrationFactor is added to the zoo_taxonomyProcessed and zoo_taxonomyRaw tables and used in calculation of adjCountPerBottle, along with updated values for zooSubsampleVolume.
The data have been corrected and the field adjCountPerBottle recalculated for both the zoo_taxonomyProcessed and zoo_taxonomyRaw tables. The corrected data are published in the 2025 Data Release.
