, 2011 It has been proposed that cosmic ray events could have a causal relationship with cloud formation rates. Given the weak constraints on the role that cloud formation plays in climate forcing it is essential to understand the role such a relationship could

Meteoritics &Planetary Science, EarlyView.Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

, 2016 An oscillation with a period of about 2100-2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (C-14 and Be-10) and in paleoclimate records throughout the Holocene. Herein we demonstrate the astronomical origin of this cycle.

Mining an Anthropocene in Japan: On the making and work of geological imaginaries
Transactions of the Institute of British Geographers, EarlyView.Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract We aim to isolate predominantly solar modulated (multi‐decadal to centennial) production changes in a 10Be record from Black Sea sediments covering Termination 2. In addition to the effects of varying climate and sedimentation, sea level rise and tephra‐driven Be relocation introduced non‐production biases into our 10Be (and 9Be) records ...

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as one of the primary drivers of energetic electron precipitation (EEP) into the Earth's atmosphere. A problematic discrepancy has remained between the occurrence frequency of waves in magnetic local time (MLT) and the resultant precipitation observed by satellites.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract Atmospheric planetary waves play an important role in shaping how the ionosphere is coupled to the rest of the Earth's atmosphere. Of significant interest in this study are the 2‐, 3‐, and 6‐day planetary waves. Using multiple long‐term datasets, we performed an extensive survey of these wave events in the atmosphere and ionosphere.

Earth and Space Science, Volume 12, Issue 6, June 2025.Abstract To explore the hypothesis of a common source of variability in two time series, observers may estimate the magnitude‐squared coherence (MSC), which is a frequency‐domain view of the cross correlation. For time series that do not have uniform observing cadence, MSC can be estimated using Welch's overlapping segment averaging.
