Jennifer Lynn Lewicki, PhD

I am a volcano geochemist whose research quantifies temporal and spatial variations in gas and heat emissions, seeks to understand the processes that drive these variations, and evaluates the state of magmatic and/or volcanic activity.

Comparative soil CO2 flux measurements and geostatistical estimation methods on Masaya volcano, Nicaragua Comparative soil CO2 flux measurements and geostatistical estimation methods on Masaya volcano, Nicaragua

We present a comparative study of soil CO2 flux (FCO2) measured by five groups (Groups 1–5) at the IAVCEI-CCVG Eighth Workshop on Volcanic Gases on Masaya volcano, Nicaragua. Groups 1–5 measured FCO2 using the accumulation chamber method at 5-m spacing within a 900 m2 grid during a morning (AM) period. These measurements were repeated by Groups 1–3 during an afternoon (PM) period...
