Tethered Aircraft-Unmanned System (TAUS)
The tethered aircraft-unmanned system (TAUS) is an unmanned platform prototyped for high-throughput environmental monitoring. TAUS has been field-tested and has recorded continuous flight times of more than six hours in remote locations using battery power. Tethered to a power source on the ground, TAUS is able to operate for extended periods of time and, thus, overcome the main limitation of existing unmanned aerial systems (UASs). The novelty of this system comes from leveraging the physical presence of the power tether by integrating sensors along it. With this feature, the system can acquire atmospheric data at multiple altitudes and produce a gradient.
Daniel Rico explains the system further in this TAUS video.

Education and communication products of the Council for Resilience Education
Eight NRT students and two other graduate students founded the Council for Resilience Education and registered it as an official student organization at the university. The council produces online articles, case studies, games, videos, and podcasts to explain resilience theory and strategies for addressing environmental problems. Members of the council have developed a way to each ecological resilience concepts using the game Jenga and have recorded instructions. They have also completed six education modules, Ecological Resilience, Alternative Stable State Theory and Regime Shifts, Scale, Heterogeneity, Adaptive Cycle, and Panarchy hosted online at the Plant & Soil Sciences eLibrary of the university. The elibrary serves as a free resource to teachers, students and anyone else seeking background on specific scientific topics. It receives about 11.5 million hits yearly and offers lessons and animations in English and Spanish.
The council has produced several episodes of the podcast, "What the Heck is Resilience, Anyway?" These can be found on Soundcloud, Apple Podcasts, Spotify and Stitcher (see https://soundcloud.com/whra).

The Hydraulic Parameter Estimation Tool (HydraPET) is a program that handles detailed descriptions obtained from geologists’ borehole logs. It is a pattern-recognition algorithm that translates lithology descriptions into a standard set of terms while providing estimated hydraulic conductivity (K) and specific yield (Sy) values based on lithological modifiers such as grain size or clay content. HydraPET (v 1.0, 1.1, 1.2, 1.2.1, and 2.0) was developed in Python with a modular approach.

The Multiplexer is both a hardware and software system intended for automatic water sampling from 16 separate mesocosms. Each mesocosm has a particular level of water contamination but with varying levels of natural means of contamination sequestration. When the system is coupled with a spectrometer, water quality analysis over time is possible. The software was developed in C, with a modular approach.

The Plant Trait Data Sifter is a software tool to assemble summaries of open-access data from plant trait databases. The program scrapes the back-end html code from a website containing an embedded table, cleans up the html until only the data remains and sorts through the cleaned data looking for particular plant species the user defined in the input files. Once entries in the table have been exhausted, the PTDS returns the matched lines of data and the performance of the search in regard to input misses in an Excel workbook for further user analysis. PTDS is programmed in Python using a modular approach. Versions 1.0 and 1.1 are in operation, and superseding variants are planned.
