Design, deploy, and test a next-generation wireless phased seismic array for seismic data collection. The seismic array configuration has been discussed theoretically but hasn’t been demonstrated in practice.
Installation of two VHF radio telemetry receiving antenna arrays, associated coaxial cables, and automatic recording unit to monitor native Hawaiian birds outfitted with radio transmitters. NEON also provides as-needed maintenance, and network access for automated data uploads and retrieval.
Obtain bacterial isolates from plants rhizospheres to i) screen the isolates for the production of secondary metabolites, ii) understand patterns of secondary metabolite production in root microbiomes, and iii) pair information about secondary metabolite repertoires in these isolates with soil chemistry to understand the biogeography of secondary metabolite production.
Examine visible to shortwave infrared reflectance using a NoX (Near infrared Box, JB Hyperspectral) mounted on the NEON flux tower.
Installation of a 2-way radio antenna on the NEON tower and repeater in the instrument hut to provide better 2-way coverage across the entire University of Notre Dame Environmental Research Center (UNDERC) property.
Investigating forest dynamics, and the fine-scale phenology (either current year or previous year) that may be correlated with woody plant mortality or growth
Measure sap flow for changes over time by measuring radial and azimuthal variation in sap flow using custom built sap flow sensors.
Evaluate the performance of the Ribbit Network sensors. Comparisons of absolute and relative accuracy of CO2 concentration, temperature, humidity, and barometric pressure observations. Evaluation against NEON sensors will help us better understand how well the sensors perform in a variety of weather conditions, and learn how future work could use dense arrays of the low-cost sensors to investigate CO2 concentration heterogeneities, and potentially fluxes, in real-time.
Monitor the density and fluctuation of Earth’s ionosphere using ground-based Global Navigation Satellite System (GNSS) receivers. Specifically we want to understand how the ionosphere changes in response to auroral energy input. Certain Alaska NEON sites would be included in a larger network (25 total in Alaska, and 10 in Canada) to monitor the density and fluctuation of Earth’s ionosphere using ground-based GNSS.
Investigate how a foundation plant species (Fremont cottonwood) distributed across three major ecoregions in the southwestern U.S. responds to the synergistic impacts of climate-induced drought and temperature change, coupled with exotic species invasion
