Estimating age of rock cairns in southeast Alaska by combining evidence from successional metrics, lichenometry, and carbon dating [PDF]
Arctic Science, 2017 We estimated ages of rock cairns in alpine tundra in southeast Alaska by combining information from three general classes of methods, each of them imperfect, but considered together providing better estimates than any of the three alone.

Lichen Growth and Lichenometry [PDF]
Geografiska Annaler: Series A, Physical Geography, 2014 Certain species of crustose lichens have concentrically zoned margins which probably represent yearly growth rings. These marginal growth rings offer an alternative method of studying annual growth fluctuations, establishing growth rate-size curves, and determining the age of thalli for certain crustose species. Hence, marginal growth rings represent a

Lichenometry in Iceland, results and application [PDF]
Géomorphologie : relief, processus, environnement, 2016 This paper proposes a review of the use of lichenometry in Iceland since 1970, using different techniques to solve the chronology of geomorphic processes. Most users have sought to date proglacial landforms in two main areas: around the southern ice-caps of Vatnajökull and Mýrdalsjökull and in the Tröllaskagi peninsula in the north.

BoreasGljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii ...

Topsoil organic matter build-up in glacier forelands around the world. [PDF]
Glob Chang Biol, 2021 In glacier forelands all over the world, the organic matter build‐up during the initial stages of topsoil development is strongly modulated by climate: a warmer climate accelerates accumulation of organic matter. We also detected a decreasing thermal stability of soil organic matter along the chronosequences. The observed changes in soil organic matter

Lichenometry: field work for schools and colleges [PDF]
Journal of Biological Education, 1989 Using lichens to date monuments, buildings, and the exposure of surfaces in general can be the basis of a worthwhile field project. It uses only simple equipment yet requires a systematic approach to solving the problem. Lichenometry can be developed for use at almost any level including teacher training and inset work.
