Delay in analysis of external lab surface water and groundwater nutrient data

January 25, 2021

Based on an analysis of nutrient data, NEON has determined that the method detection limits (MDLs) required of the external laboratory for surface water and groundwater nutrient analyses are too high for many sites. New analyses of frozen samples will take place in the future.

Women in Ecology – Alex Harmon-Threatt

January 20, 2021

Dr. Harmon-Threatt, associate professor of entomology at the University of Illinois School of Integrative Biology, discusses how her mentors first opened her eyes to the possibility of pursuing a career in ecology and how she hopes to provide the same opportunities to her female students, especially those of color, to increase the representation of women of color in academia and the natural sciences.

Surface water microbe cell count (DP1.20138.001) lab data corrections pending

January 20, 2021

Surface water microbe cell count (DP1.20138.001) laboratory data for all aquatic sites from 9/2017 to 9/2020 were found to have incorrect calculations populating rawMicrobialAbundance data field. Data have been removed from the data portal while revisions are made and will be republished by February.

Plant and soil samples not re-dried prior to carbon/nitrogen analyses, impacts to data quality

January 19, 2021

Due to a miscommunication, samples analyzed for carbon (C) and nitrogen (N) concentrations and stable isotopes were not previously re-dried prior to weighing and analysis at the external laboratory. Affected data have been flagged and a new protocol was implemented.

Resolved: Surface water and groundwater elevation data improvements

January 14, 2021

To reduce uncertaintly in surface and groundwater elevation data, permanent benchmarks have been installed at most aquatic sites to serve as controlled location reference points. Updated elevations from the associated site resurveys are available on the data portal. Surface and groundwater elevation data products have been reprocessed, and, the corrected data will be available via the data portal by January 18, 2020.

Getting to Know the NEON Domains: Great Lakes

December 30, 2020

The Great Lakes Domain (D05) is named for its most recognizable feature: the Great Lakes themselves. At our field sites in Wisconsin and Michigan, we're collecting data representing different management practices in the northern pine and hardwood forests. The data will help researchers understand how land management practices impact both terrestrial and aquatic ecosystems in the Great Lakes region.

Sorting Out the Taxonomy of North American Diatoms

December 23, 2020

An investigation into freshwater diatoms from the NEON aquatic field sites in Puerto Rico led to a reclassification of diatom taxa in the region, and the possible discovery of a new diatom species. A paper recently published in Phytotaxa details the results of the research, which was enabled by samples from the NEON Biorepository.

Upcoming Error Corrections for Tick Data

December 21, 2020

We have discovered an error in the larval tick count data collected in 2016-2017 in Ticks sampled using drag cloths (DP1.10093.001) that affects all sites. Samples from the tick taxonomy laboratory had a count of 1 larva in the taxonomy table no matter how many individuals were present in the sample. The data will be rectified within 2-3 weeks.

Resolved: Temporary removal of foliar trace element data

December 15, 2020

The sunlit plant foliage major, minor, and trace element data (DP1.10026.001, cfc_elements table) collected in 2017 and 2018 were investigated and deemed untrustworthy. Sample major, minor, and trace elements were re-measured using foliar material from the NEON Biorepository. Following review, these new data were posted to the Data Portal on 2020-10-29.

Soil Moisture Validation Project Highlights Synergies Between Battelle, NASA Programs

December 4, 2020

NASA monitors soil moisture levels and freeze/thaw conditions across the globe using a satellite orbiting 426 miles (685 km) above the Earth. To help validate and calibrate these satellite data, NASA relies on direct measurements taken by partners on the ground. Through a new collaboration with Battelle, soil moisture data collected at the National Ecological Observatory Network (NEON) field sites will now be part of those validation efforts.

Fluctuations in Buoy Sonde Depth Data

November 23, 2020

At all sites with profiling water quality sondes on buoys, the Water quality data product (DP1.20288.001) reports the depth of the multisonde as it profiles through the water column. Data users should be aware that sensor depth is approximate, as the multisonde’s pressure transducer is not vented to the atmosphere. Therefore, barometric pressure fluctuations following calibration will cause a sensor depth discrepancy.

Errors were discovered in NEON.DOC.004931 (version A), the Algorithm Theoretical Basis Document (ATBD) for the Water quality (DP1.20288.001) data product. These errors impact the temperature and absorbance corrections applied to fluorescent dissolved organic matter (fDOM) data.

Where Does the Water Go? Partitioning Evaporation and Transpiration

November 5, 2020

How much of the water that enters terrestrial systems is used by plants for growth, and how much simply escapes back into the atmosphere unused? Chris Adkison, a researcher at Texas A&M University, used data from the NEON program to compare the accuracy of different methods of partitioning evaporation and transpiration in a Texas oak woodland.
