Landscape-scale establishment and population spread of yellow-cedar (Callitropsis nootkatensis) at a leading northern range edge [PDF]

, 2016
Thesis (M.S.) University of Alaska Fairbanks, 2016Yellow-cedar is a long-lived conifer of the North Pacific Coastal Temperate Rainforest region that is thought to be undergoing a continued natural range expansion in southeast Alaska.

Geomorphology of the Durmitor Mountains and surrounding plateau Jezerska Površ (Montenegro) [PDF]

, 2014
The geomorphological map of the northeastern Durmitor Mountains and the plateau Jezerska Povrs. (1: 10,000, 47 km(2), Montenegro, Dinaric Alps) was prepared from an intensive fieldwork campaign and remote sensing analysis, and was compiled within a GIS ...

Ice shelf evolution combining flow, flexure, and fracture

Journal of Glaciology
Ice shelves regulate ice sheet dynamics, with their stability influenced by horizontal flow and vertical flexure. MacAyeal and others (2021) developed the theoretical foundation for a coupled flow-flexure model (the “M21 model”), combining the Shallow ...

The shallow shelf approximation as a "sliding law" in a thermomechanically coupled ice sheet model

, 2008
The shallow shelf approximation is a better ``sliding law'' for ice sheet modeling than those sliding laws in which basal velocity is a function of driving stress.

Sedimentological characterization of Antarctic moraines using UAVs and Structure-from-Motion photogrammetry [PDF]

, 2015
In glacial environments particle-size analysis of moraines provides insights into clast origin, transport history, depositional mechanism and processes of reworking.

Reduced basal motion responsible for 50 years of declining ice velocities on Athabasca Glacier

Journal of Glaciology
The time-evolution of glacier basal motion remains poorly constrained, despite its importance in understanding the response of glaciers to climate warming.

New Constraints on the Timing and Pattern of Deglaciation in the Húnaflói Bay Region of Northwest Iceland Using Cosmogenic 36CA Dating and Geomorphic Mapping

, 2017
Understanding the evolution and timing of changes in ice sheet geometry and extent in Iceland during the Last Glacial Maximum (LGM) and subsequent deglaciation continues to stimulate much active research.

Global glaciological models: a new stage in the development of methods for predicting glacier evolution. Part 1. General approach and model architecture

Лëд и снег, 2022
For several decades, mathematical models of mountain glaciers and ice sheets have been used to study the dynamics of the cryosphere. In recent years, a new step in glaciological modeling has made possible to recon- struct processes in mountain-glacial ...
