Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

Dendrochronology: A Status Report for the Eastern United States [PDF]

open access: yes, 2012
Architectural historians and historic preservation practitioners have turned with increasing frequency to dendrochronology to determine dates of construction for houses and other timber structures for which the application of traditional dating ...

Addressing Biases in Ice Jam Observations by Integrating Multi‐Source Data in a Forested Fluvial Landscape, Southern Quebec

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1188-1208, July 2026.
ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation

ELM Dendrochronology [PDF]

open access: yes, 2020
Elm is generally considered to be unsuitable for dendrochronology, usually having too few rings, or having abrupt growth-rate changes that do not result from the external weather conditions. Samples rarely match each other in the same structure.

Impact of climate and environmental changes on forest ecosystem's productivity (case study: Galugah) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2013
According to the results of the current research, a new approach in application of dendrochronology, using broadleaved tree rings, as main element of productivity, to evaluate forest ecosystem productivity, has been introduced.

Analysis of Site-dependent Pinus halepensis Mill. Defoliation Caused by ‘Candidatus Phytoplasma pini’ through Shape Selection in Landsat Time Series

open access: yesRemote Sensing, 2019
High levels of ‘Candidatus Phytoplasma pini’ have produced extensive forest mortality on Pinus halepensis Mill forests in eastern Spain. This has led to the widespread levels of forest mortality.

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
