Climate and human exploitation have regulated Atlantic salmon populations in the River Spey, Scotland, over the last 2000 years (2022)
Journal Article

Historical salmon catch records suggest that climatic variability, and more recently human exploitation, control patterns of abundance in Atlantic salmon populations. We present the first long-term (2000-year) reconstruction of Atlantic Salmon popula...

Micromilling vs hand drilling in stable isotope analyses of incremental carbonates: The potential for δ 13C contamination by embedding resin (2022)
Journal Article

Micromilling vs hand drilling in stable isotope analyses of incremental carbonates: The potential for δ 13C contamination by embedding resin. Rapid Communications in Mass Spectrometry, 36(14), Article e9318. https://doi.org/10.1002/rcm.9318

Rationale: Embedding resins are commonly used to facilitate high-resolution sampling for stable isotope analysis but anomalous δ13C values have been observed in some cases. Here we compare the results of microsampling strategies for hand-drilled vers...

The importance of climate change, specifically drought, across the Maya region in the northern Neotropics, remains a topic of lively debate. Part of this discussion hinges on the coherency of response to climatic variability across different archives...

The rate of deep-ocean carbon burial is considered important for modulating glacial-interglacial atmospheric CO2 concentrations and global climate during the Quaternary. It has been suggested that glacial iron fertilization and increased efficiency o... Read More about Silicic Acid Cycling in the Bering Sea During the Mid-Pleistocene Transition.
