Fugitive Methane Monitoring: A Systems Review of Physics, Technology, Economics, and Regulation

P. Sobrón

Fugitive methane emissions from fossil fuel operations exceed 120 million tonnes per year globally, yet measurement campaigns consistently find actual emissions to be roughly twice the levels reported through inventory-based self-reporting, and up to three times higher in the most intensively studied …

Reevaluating Convolutional Neural Networks for Spectral Analysis: A Focus on Raman Spectroscopy

Deniz Soysal, Xabier García-Andrade, Laura E. Rodriguez, P. Sobrón et autres

Autonomous Raman instruments deployed on Mars rovers, deep-sea landers, and mobile field robots must interpret raw spectra that are distorted by fluorescence baselines, peak shifts, and limited ground-truth labels. Using rigorously documented subsets of the RRUFF mineral database, we systematically evaluate one-dimensional …

Sensing Remote Realms of the Deep Ocean on Earth—and Beyond

Anastasia Yanchilina, Laura E. Rodriguez, Roy Edward Price, Laura M. Barge et autres

A novel laser-equipped probe is collecting measurements of deep-sea geochemical environments that once seemed impossible to gather, pointing the way toward future explorations of other ocean worlds.

Palaeo-environmental significance of evaporative calcite crusts in the Untersee Oasis, East Antarctica

Denis Lacelle, Michelle Christy, Benoit Faucher, P. Sobrón et autres

Abstract Secondary carbonate precipitates on the surface of clasts have rarely been reported from Antarctica. Here, we infer the origin, age and palaeo-environmental significance of the calcite crusts in the Untersee Oasis, East Antarctica. The distribution of calcite crusts, which are up …

Surface Morphologies in a Mars-Analog Ca-Sulfate Salar, High Andes, Northern Chile

Nancy W. Hinman, Michael H. Hofmann, Kimberly Warren-Rhodes, Michael Phillips et autres

Salar de Pajonales, a Ca-sulfate salt flat in the Chilean High Andes, showcases the type of polyextreme environment recognized as one of the best terrestrial analogs for early Mars because of its aridity, high solar irradiance, salinity, and oxidation. The surface of …

Oceans Across the Solar System and the Search for Extraoceanic Life: Technologies for Remote Sensing and In Situ Exploration

Ved Chirayath, Elizabeth Bagshaw, Heidi Heidi, Darlene S. S. Lim et autres

Earth’s ocean comprises 99% of the habitable volume of our planet and contains the largest biomass and species diversity in the known universe. Perhaps unsurprisingly, recent advances in the search for life elsewhere in our solar system have increasingly pointed to potentially …
