title: Reaeration field and lab collection (DP1.20190.001)
title: RELEASE-2022

description: This data product contains the quality-controlled, native sampling resolution data from NEON's wadeable stream reaeration sampling protocol. During most reaeration experiments, grab samples of stream water at NEON aquatic sites are collected in streams at 4 sampling locations downstream of a continuous injection of an inert gas (SF6) and conservative tracer (NaCl or NaBr). Background samples are collected prior to tracer injection and are analyzed for background salt tracer concentrations. Plateau samples are collected once the tracer concentration reaches a constant concentration (as measured by conductivity) and 5 replicate samples from each station are analyzed for both salt and gas tracer concentrations. Data users should refer to the user guide for reaeration and salt-based discharge see `NEON_ReaerSaltBasedQ_userGuide` for suggestions on how to calculate reaeration rates from the published data packages. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. During some reaeration experiments, denoted by injectionType “model - slug” or “model - CRI”, only the conservative tracer is injected, either via slug or constant rate, (i.e., inert gas is not injected). See NEON Data Product User Guide to Reaeration (DP1.20190.001) and Salt-based Discharge Sampling (DP1.20193.001) for more detail about when and where model type injections are used.

description: Tracer injections are completed 6 times per year to capture a range of flows at NEON wadeable stream sites. The first sampling station is located near sensor set #1 and the fourth sampling station is located near sensor set #2. Sampling stations #2 and #3 are approximately evenly spaced between sampling stations #1 and #4. The injection (drip) station is located far enough upstream of sampling station #1 that the tracer is well mixed within the stream channel for all sampling stations. Conductivity data loggers are located near sampling stations #1 and #4 to capture the rising limb and plateau (for constant rate injections) and falling limb (for slug injections) in situ conductivity values.

description: Soil sampling occurs annually at a minimum of one site per domain and once (sites with short growing seasons) to three times per year (sites with longer growing seasons), with collections ocurring at every sampled site during the historic peak in vegetation greenness. Three pre-determined, randomly assigned locations are selected for each sampling event within each of 10 plots distributed throughout a site; sampling locations within a plot are not re-sampled. Soil samples are collected to a maximum depth of 30 cm, with organic and mineral soils sampled separately. The same samples are used for measurement of soil physical and chemical properties to maintain temporal and spatial connectivity. Subsamples of homogenized soil (rocks, roots and organic debris removed) from each of the three sampling locations are stored in sterile containers, frozen on dry ice in the field and shipped to an analytical facility for DNA extraction, sample preparation and high-throughput sequence analysis using primer sets targeting the small subunit of the ribosomal RNA gene operon. Laboratory metadata are passed through the NEON automated ingest process for QC testing and are published on the NEON data portal. DNA sequence data undergo QC testing and unique URLs are generated to enable data download.

title: RELEASE-2022

description: This data product contains the quality-controlled, native sampling resolution data from NEON's aquatic periphyton and phytoplankton collection and field metadata, as well as associated taxonomic,  and enumeration data provided by contracted labs. Benthic and water column field samples are collected in wadeable streams, rivers, and lakes three times per year during the growing season. Samples are separated into aliquots for taxonomic analysis at the domain support facility (preserved in glutaraldehyde or Lugol's iodine) for shipment to a external facilities, or filtered onto glass-fiber filters for biomass (ash-free dry mass). For additional details, see the user guide, protocols, science design, and lab SOPs listed in the Documentation section in this data product's details webpage.

description: Periphyton and phytoplankton samples are collected three times per year at wadeable stream, river, and lake sites during aquatic biology bout windows, roughly in spring, summer, and fall. Samples are collected using the most appropriate sampler for the habitat and substratum type, including rock scrubs, grab samples, and epiphyton. In wadeable streams, periphyton samples are collected in the two most dominant benthic habitat types (e.g. riffles, runs, pools, step pools). In lakes, water-column phytoplankton samples are collected near the buoy and littoral sensors using a Kemmerer sampler, and in littoral areas using the best benthic sampling method for the substratum type. In rivers, phytoplankton samples are collected near the buoy and two other deep-water locations using a Kemmerer or Van Dorn sampler, and in littoral areas using the most benthic sampling method for the substratum type. All field-collected samples are split into subsamples in the domain support facility, which are either processed in the facility (ash-free dry mass) or preserved and shipped to a contracting taxonomy laboratory. Diatoms and soft algae are identified and enumerated at the external taxonomy lab. Reference images are also collected. Slides and preserved subsamples are archived at the NEON Biorepository after analysis.

description: Up to thirty Distributed Plots and three Tower Plots are measured at each site. Plots are sampled annually at most sites to correspond with peak greenness, and twice a year at select sites with bimodal peaks in greenness and species composition. The multi-scale plot design is consistent with methods of the Carolina Vegetation Project. The files provided with this data product also include records of plant vouchers and foliar tissue for analyses by the ecological community that are stored at external archives, and a table to facilitate the resolution of species not identified when encountered in the field during observation and data entry.

Records are reported about management activities and disturbances that have the potential to impact or affect data products across all NEON data-generating systems (TIS, TOS, AIS, AOS, and AOP) that are not collected as part of existing data product protocols. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

sim_eventData: 60
description: Site management activity and disturbance reporting occurs at the time NEON staff are aware of the planned or unplanned event, either through direct observation during normal scheduled site visits or secondary reports from landowners, site hosts, and other reliable sources. For planned events, reporting is expected to occur only after the management activity has been started. For unplanned events, data recording takes place as soon as the disturbance is observed as well as when it is safe to assess the scale and intensity of the impact.

title: 2D wind speed and direction (DP1.00001.001)
title: RELEASE-2022

description: Wind plays an important role in atmospheric and environmental sciences. A function of differential heating of Earth’s surface and subsequent pressure gradients, horizontal and vertical winds are responsible for advection of atmospheric pollutants, moisture, heat and momentum (Stull 1988). As such, horizontal and vertical winds will be measured throughout the Observatory.

Latency:
Data collected in any given month are published during the second full week of the following month.
description: Multiple 2D anemometers are deployed at tower sites. They are located on each boom arm below the tower-top level at terrestrial sites. A single 2D anemometer is located at the top of the aquatic met station at a standard height of 3m above ground level. Two- and thirty-minute averages of horizontal wind speed and direction are calculated. Each 2D anemometer represents the point at which it is placed on the tower infrastructure. Instrumentation: Gill - Wind Observer II; Extreme Weather Wind Observer
