Chronology of Central European Impulses in the Volga Forest Region: Fatyanovo and Abashevo Cultures

Поволжская археология, 2023
There is a difference in chronology based on radiocarbon dating and historical dates associated with Near Eastern written sources. With the introduction of AMS dating, this gap has become smaller, but has not disappeared.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Airborne Laser Scanning Cartography of On-Site Carbon Stocks as a Basis for the Silviculture of Pinus Halepensis Plantations

Remote Sensing, 2018
Forest managers are interested in forest-monitoring strategies using low density Airborne Laser Scanning (ALS). However, little research has used ALS to estimate soil organic carbon (SOC) as a criterion for operational thinning.

Facilitative Effects of Alnus viridis ssp. fruticosa on Betula nana ssp. exilis Growth in Arctic Alaska

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We investigated how Siberian alder influences the growth of dwarf birch in the low Alaskan Arctic. Using growth rings, we found that Siberian alder promotes dwarf birch growth overall despite delaying and shortening the growing season through enhancing snow depths.

Assessing spatial distribution and quantification of native trees in Saskatchewan’s prairie landscape using remote sensing techniques

European Journal of Remote Sensing
The importance of trees in non-forest landscapes has been the focus of only a few studies. However, these trees provide many important ecosystem services. In this study, we mapped and quantified these trees using Sentinel-2 (S2) and very high-resolution (

Assessment of the Carbon Stock in Pine Plantations in Southern Spain through ALS Data and K-Nearest Neighbor Algorithm Based Models

Geosciences, 2019
Accurate estimation of forest biomass to enable the mapping of forest C stocks over large areas is of considerable interest nowadays. Airborne laser scanning (ALS) systems bring a new perspective to forest inventories and subsequent biomass estimation ...

Dendrochronology and radiocarbon dating

, 2022
Both dendrochronology and radiocarbon (¹⁴C) dating have their roots back in the early to mid-1900s. Although they were independently developed, they began to intertwine in the 1950s when the founder of dendrochronology, A. E.

Radiocarbon Calibration for Japanese Wood Samples [PDF]

, 2003
The radiocarbon content of Japanese cedars was measured by accelerator mass spectrometry for decadal tree-ring samples from the period of 240 BC to AD 900. Conventional gas counting was also used for part of the samples.

Loess Studies in Aotearoa New Zealand

New 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.
