Autor: Joshua D. Landis, Daniel Obrist, Jun Zhou, Carl E. Renshaw, William H. McDowell, Christopher J. Nytch, Marisa C. Palucis, Joanmarie Del Vecchio, Fernando Montano Lopez, Vivien F. Taylor

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)

Abstract Soils are a principal global reservoir of mercury (Hg), a neurotoxic pollutant that is accumulating through anthropogenic emissions to the atmosphere and subsequent deposition to terrestrial ecosystems. The fate of Hg in global soils remains

Remote and in-Situ Characterization of Mars Analogs: Coupling Scales to Improve the Search for Microbial Signatures on Mars

Autor: Carolynn M. Harris, Matthew T. Maclay, Katherine A. Lutz, Vinitra Nathan, Noemi A. Ortega Dominguez, William D. Leavitt, Marisa C. Palucis

Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 9 (2022)

Past environments on Mars contained abundant water, suggesting certain regions may have been conducive to life as we know it and implying the potential for microbial inhabitants. Gale and Jezero craters, home of the Perseverance and Curiosity rovers,

Do Deltas Along the Crustal Dichotomy Boundary of Mars in the Gale Crater Region Record a Northern Ocean?

Autor: Frances Rivera‐Hernández, Marisa C. Palucis

Publikováno v: Geophysical Research Letters, Vol 46, Iss 15, Pp 8689-8699 (2019)

Abstract Deltaic deposits mapped along the Martian crustal dichotomy boundary scarp have been suggested to delineate an ancient ocean in the northern lowlands of Mars. Using recently acquired orbital data, we have expanded the dichotomy delta invento

Rates and processes controlling periglacial alluvial fan formation: Implications for martian fans

Autor: Marisa C. Palucis, A.M. Morgan, J.V. Strauss, F. Rivera-Hernandez, J.A. Marshall, E. Menio, R. Miller

Publikováno v: GSA Bulletin. 135:937-954

Alluvial fans are found across a range of climates and are built from a combination of fluvial and debris flow processes. Correct identification of process is critical to reconstructing the climate and water histories of alluvial fans on Earth and Ma

Debris flow initiation from ravel-filled channel bed failure following wildfire in a bedrock landscape with limited sediment supply

Autor: Marisa C. Palucis, Michael P. Lamb, Thomas P. Ulizio

Publikováno v: GSA Bulletin. 133:2079-2096

Steep, rocky landscapes often produce large sediment yields and debris flows following wildfire. Debris flows can initiate from landsliding or rilling in soil-mantled portions of the landscape, but there have been few direct observations of debris fl
