Evaluation of Matrix Effects in SIMS Using Gaussian Process Regression: The Case of Olivine Mg Isotope Microanalysis

Rapid Communications in Mass Spectrometry, Volume 39, Issue 13, 15 July 2025.
ABSTRACT Rationale Matrix effects by secondary ion mass spectrometry (SIMS) are empirically corrected by calibration using matrix‐matched reference materials. However, conventional parametric regression cannot estimate the prediction uncertainty to account for the difference in compositions of new data and reference materials. Applying Gaussian process

Multispectral Observations of Float Rocks Used to Investigate the Origin of Boulders on the Western Jezero Fan Front, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract In Jezero crater, Mars, the Perseverance rover has explored the western fan and encountered loose pieces of rock separated from outcrops or “float” rocks. Comparing float rocks to in‐place outcrops can provide key insights into the crater's erosional history and the diversity of units in the Jezero watershed that Perseverance cannot visit in ...

Sphagnum Peatland Hydrological Balance Shows High Groundwater Dependence and Resilience to Short‐Term Dry Periods

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Quantifying the hydrological connectivity of wetland ecosystems is crucial for their sustainable management and conservation. Australian mountain peatlands typically form and persist on sloping terrain downstream of groundwater springs. This suggests that they depend heavily on groundwater inputs.
