Quaternary erosion in the Sognefjord drainage basin, westernNorway
Catchment area;Watershed ; Fjord ; Glacial erosion ; Glacial features ; Norway ; Numerical model ; Palaeogeography ; Quaternary
The preglacial landscape configuration in the Sognefjord drainage basin of westernNorway is reconstructed, and the total Quaternary erosion is quantitatively determined to 7 610 km3 by subtracting the present topography from the reconstructed
This paper reports on relative and absolute age estimates on a sequence of Holocene moraines on the floor of the Jardalen cirque complex near Sandane, westernNorway, based predominantly upon simple and inexpensive field criteria. The available soil
development rates for this part of Norway are used to calculate moraine ages and to construct an absolute chronology for the moraine sequence, which is compared to a previously published lichenometric chronology for the same cirque basin.
Little ice age alluvial fan development in Langedalen, westernNorway
Alluvial cone ; C 14 dating ; Climatic variation ; Geochronology ; Little ice age ; Norway ; Palaeo-ecology ; Palaeogeography ; Pollen analysis ; Sedimentology
This paper reports a preliminary investigation of the sedimentary succession in 2 alluvial fans in westernNorway. Sedimentological information is supplemented by palaeoecological data from pollen analysis and the age of the sequence is constrained
, to western Greenland with a natural population of reindeers, and finally to northern Norway, where overgrazing already exceeds the carrying capacity. With the help of ecological mapping, especially of vegetation and soils, and measurements of environmental
A long-term landscape ecological project in Central Norway offers new material that is used to interpret the grazing impact of reindeers in comparable ecosystems. A gradient was studied from central Norway, where there is no reindeer grazing
Late Weichselian and Holocene sea-level history for a cross-section of westernNorway
The postglacial sea-level history along a cross-section of westernNorway has been studied in detail. Ten local sea-level curves were used to construct an equidistant shoreline diagram, covering the last 13 000 years. This includes 76 radiocarbon
A numerical model with grid resolution 500 m has been used to simulate tides on this section of the shelf off the coast in westernNorway. The fine spatial resolution resolves important fine scale features of the bottom topography on the shelf
Grazing history affects the tree-line ecotone : a case study from Hardanger, WesternNorway
Climatic change ; Ecosystem ; Ecotone ; Forest ; Historical geography ; Mountain ; Norway ; Pastureland ; Tree line
This study compares the tree and ground cover of 2 localities having different grazing histories in the tree-line ecotone of WesternNorway. Data from the sampling of trees, saplings, seedlings and ground cover, tree age determinations, aerial
Moraine formation at an advancing temperate glacier : Brigsdalsbreen, westernNorway
Climatic variability ; Erratic boulder ; Glacier ; Glacier advance ; Grain size distribution ; Moraine ; Norway ; Proglacial lake ; Temperate zone
Owing to increased winter balances especially since 1988/89, almost all valley outlet glaciers of Jostedalsbreen in westernNorway are experiencing the largest advance since that of the early 18th century, the regional Little Ice Age maximum
The goal of this paper is to present results of ongoing investigations on fluvial sediment transport and fluvial sediment yields during thermally and pluvially induced runoff events in the glacier-fed Erdalen catchment in Nordfjord, westernNorway

This study aims to characterize the morphology and contemporary floodplain deposit dynamics within a braided sandur system in upper Erdalen, a steep U-shaped valley in westernNorway. Based on field observations, 2 different sub-systems can

A Younger Dryas ash bed in westernNorway, and its possible correlations with tephra in cores from the Norwegian Sea and the North Atlantic
A bed of volcanic ash up to 23 cm thick is found in lacustrine and marine sediments in westernNorway. It is formally named the Vedde Ash Bed, and its age is approximately 10,600 yr B.P., i.e., mid-Younger Dryas. The bed consists of pure glass
