3D Joint Inversion of Scanning Magnetic Microscopy Data
(Journal article; Peer reviewed, 2021)Scanning magnetic microscopy (SMM) is a modern magnetometry technique that maps the magnetic anomalies resulting from small-scale variations of remanent magnetization within a sample. This information is vital to understand ... -
Inequal responses of drylands to radiative forcing geoengineering methods
(Journal article; Peer reviewed, 2019)Climate geoengineering has the potential to reduce global warming. However, the nonlinear responses of Earth's large‐scale circulation to climate geoengineering can exacerbate regional climate change, with potential ... -
Magnetic phases in hemo-ilmenite: Insight from low-velocity and high-field Mössbauer spectroscopy
(Journal article; Peer reviewed, 2007)[1] We have studied natural samples of hemo‐ilmenite (ilmenite with hematite exsolution lamellae) by use of Mössbauer spectroscopy. The samples are from the Allard Lake intrusion in Quebec. The stoichiometric compositions ... -
Magnetic properties of anorthosites: A forgotten source for planetary magnetic anomalies?
(Journal article; Peer reviewed, 2008)[1] Anorthosites, igneous rocks very rich in plagioclase, rarely considered to be strongly magnetic, are common on Earth, and the Moon, and inferred to be on other planets. Magnetic properties of anorthosites could be ... -
Micromagnetic Modes of Anisotropy of Magnetic Susceptibility in Natural Magnetite Particles
(Peer reviewed; Journal article, 2022)Anisotropy of magnetic susceptibility (AMS) is commonly used to assess sedimentation, deformation, tectonics, rock fabric, and texture. Using focused-ion beam nanotomography, we develop a micromagnetic method to investigate ... -
Mineral Magnetic Characterization of High-Latitude Sediments From Lake Levinson-Lessing, Siberia
(Peer reviewed; Journal article, 2021)Levinson-Lessing Lake in northern Central Siberia is a sedimentary archive characterized by continuous, widely constant sedimentation at high rates (0.7 m ka−1 for >32 ka). This study provides the first evidence of the ... -
Observational evidence of the influence of Antarctic stratospheric ozone variability on middle atmosphere dynamics
(Journal article; Peer reviewed, 2015)Modeling results have suggested that the circulation of the stratosphere and mesosphere in spring is strongly affected by the perturbations in heating induced by the Antarctic ozone hole. Here using both mesospheric MF ... -
Observations of gravity wave forcing of the mesopause region during the January 2013 major Sudden Stratospheric Warming
(Journal article; Peer reviewed, 2014)Studies of vertical and interhemispheric coupling during Sudden Stratospheric Warmings (SSWs) suggest that gravity wave (GW) momentum flux divergence plays a key role in forcing the middle atmosphere, although observational ... -
Recent acceleration of a rock glacier complex, Ádjet, Norway, documented by 62 years of remote sensing observations
(Peer reviewed; Journal article, 2018)Recent acceleration of rock glaciers is well recognized in the European Alps, but similar behavior is hardly documented elsewhere. Also, the controlling factors are not fully understood. Here we provide evidence for ... -
Storm Track changes in the Middle East and North Africa under stratospheric aerosol geoengineering
(Peer reviewed; Journal article, 2020)As a potential approach to prevent dangerous climate change, stratospheric aerosol geoengineering (SAG) aims to reflect some incoming solar radiation into space and reduce temperatures. Previous modeling studies suggest ...
