You can tell a lot from the composition of the gasses coming from active volcanoes about what is happening deep beneath. It is even possible to predict when an active volcano will erupt causing widespread damage,and determine their contribution to climate change, yet gathering this critical data can be extremely hazardous to volcanologists.
An interdisciplinary team from UNM Departments of Computer Science, Earth and Planetary Sciences and Electric and Computer Engineering received a 4-year research grant from NSF’s National Robotics Initiative to develop novel bio-inspired software and drones to measure and sample volcanic gases. The team began this collaboration back in 2017 and participated in an international field expedition to the remote and dangerous volcanoes of Papua New Guinea sponsored by the Deep Carbon Observatory in Spring of 2019. During this expedition UNM researchers Tobias Fischer, Scott Nowicki (E and PS), Matthew Fricke and undergraduate student Jaret Jones (CS) successfully sampled the plume of Tavurvur and Manam Volcanoes for Carbon-isotopes, which provided information on the ultimate sources of carbon dioxide in these volcanoes. The results are about to be published in the journal Science Advances.
Following the expedition, UNM computer scientist Melanie Moses led the team to a successful proposal for the National Robotics Initiative to program swarms of drones so they work together to map the gas concentrations around volcanoes and so discover the richest places to sample. Writing code to allow drones to autonomously and collaboratively survey volcano gasses will allow small local monitoring stations to keep an eye on volcanoes, rather than having to rely on teams of drone pilots. The computer science efforts are spearheaded by Profs. Melanie Moses, Matthew Fricke and Jarred Saia specialists in bio-inspired algorithms. Drone hardware developments are lead by Prof. Rafael Fierro from Electric and Computer Engineering. Field testing, sensor development and science application are lead by Prof. Tobias Fischer and Dr. Scott Nowicki from Earth and Planetary Sciences. The team also includes several undergraduate students, M.Sc. students and Ph.D. students who will work synergistically within the VolCAN project.
“Our ultimate goal is to develop and test drone-platforms that enable scientists to collect data from active volcanoes that improve our understanding of volcanic processes and use that knowledge to forecast eruptions and save lives” said Tobias Fischer.
