Assessing Glacial Modification of Bedrock Valleys in the Sierra Nevada, California, Using a Novel Approach [PDF]

, 2016
This study employed a semi-automated approach to evaluate the degree of glacial modification of bedrock valleys in the Sierra Nevada, California, by quantifying morphological variability in cross-sectional form assessed from ~27,000 locations throughout ...

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland

Boreas, EarlyView.
Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

GEOMORPHOLOGICAL STUDIES OF JOVAN CVIJIĆ IN BULGARIA

Zbornik Radova: Geografski institut "Jovan Cvijić", 2016
The geomorphologic studies of Jovan Cvijić in Bulgaria are crucial for many Earth scientists from the beginning of the 20th century. Cvijić laid the foundations of the morphotectonic division of the Balkan Peninsula, clarified a number of tectonic and ...

A North Greenland‐wide in situ cosmogenic 14C ice sheet chronology since the Lateglacial

Boreas, EarlyView.
Knowledge of the glacial history of the North Greenland Ice Sheet is crucial due to its high sensitivity to climate change. However, because the ice sheet in this region is predominantly cold‐based, resulting in low erosion rates, using 10Be exposure dating to establish reliable ice sheet chronologies has proven very challenging due to nuclide ...

One application of mega-geomorphology in education [PDF]

One advantage of a synoptic view displaying landform assemblages provided by imagery is that one can often identify geomorphic processes which have shaped the region and which may affect the habitability of the area over a human life time.

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, 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) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Analysis of the suitability for ecotourism in Beira Baixa region using a spatial decision support system based on a geographical information system

Regional Science Policy &Practice, EarlyView., 2022
Abstract Ecotourism can contribute to the conservation of environmental values, as well as to the development of positive synergies between agents in the tourism sector, tourists and the local population. The growing interest in tourism offers with low environmental impact, which support the local economy, translates into a competitive advantage for ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

Boreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.
