Such gases are ultimately what drive volcanism and can give precursory signals in advance of eruptions. My research involves studying the amounts, behavior, and chemistry of those gases, with a goal of improving our understanding of their role in volcanic activity. name: Patricia A. Nadeau name_qualifier: null orcid: 0000-0002-6732-3686 organization_link: https://www.usgs.gov/observatories/hvo organization_name: Hawaiian Volcano Observatory personal_statement: "Over the course of my career as a volcanologist, I have worked\ \ on a wide range of projects. But the common factor between all of them is\ \ volcanic volatiles, otherwise known as volcanic gases. My research goal has\ \ always been to better understand how those volcanic gases behave in volcanic\ \ systems, before, during, and after eruption. This has meant that I\u2019ve\ \ gotten to study how volcanic gas plumes interact with topography and vegetation\ \ in Nicaragua; the chemistry of tiny amounts of volatiles trapped within rocks\ \ erupted tens of thousands of years ago in Alaska; connections between escaping\ \ gas, seismicity, and explosive eruptions in Guatemala; and even how different\ \ volatiles dissolve in magma when you create your own tiny, high-temperature\ \ molten rock in a laboratory.Here at the Hawaiian Volcano Observatory, my focus\ \ is still volcanic gases. HVO routinely monitors gas emissions from K\u012B\ lauea and Mauna Loa volcanoes using a range of permanent measurement stations\ \ and portable instrumentation. In addition to monitoring, I conduct research\ \ on gas chemistry using MultiGAS sensors, FTIR spectroscopy, and direct sampling.\ \ For research on gas emission rates, I use UV spectrometers and UV cameras.\ \ Recently, I have also been involved in new initiatives at HVO to use UAS (unoccupied\ \ aircraft systems) to measure gas chemistry, emission rates, and sample volcanic\ \ plumes, as well as to sample the short-lived water lake at K\u012Blauea summit.\ \ I also use measurements of volatiles still dissolved in rock and mineral samples\ \ to supplement my work on gas emissions.I spent a number of years as an educator\ \ before arriving at HVO and very much value science education, especially for\ \ young students. So, in addition to my research and monitoring efforts at HVO,\ \ I participate in a number of outreach activities with students of all ages." professional_experience: - "Research Geologist \u2013 USGS Hawaiian Volcano Observatory (Hilo, HI; 2018\ \ \u2013 present)" - "Visiting Assistant Professor \u2013 Ohio University (Athens, OH)" - "Temporary Assistant Professor \u2013 Salem State University (Salem, MA)" - "Kathryn W.
