Estimating meltwater retention and associated nitrate redistribution during snowmelt in an Arctic tundra landscape
Nitrogen availability in Arctic ecosystems is a key driver for biological activity, including plant, growth and thereby directly linked to the greening of the Arctic. Here, we model the redistribution of meltwater following spring snowmelt as well as the accumulation of meltwater and dissolved nitrate at landscape scale. By combining snow mapping with unmanned aerial systems, snow chemistry, and hydrological modelling, we argue that the majority …
A method to identify potential cold-climate vine growing sites—a case study from Røsnæs in Denmark
A method for surveying the suitability of cold climate vine growing sites in Denmark is presented with focus on limiting growth parameters. The four most important parameters are identified on the basis of literary studies and discussions with approximately 150 vine growers in Denmark. These are: i) Sum of growing degree days (SDD), ii) Risk of frost damage, iii) Number of sunshine hours during growth season, and iv) Soil drainage. A two-step met…
Generating a Danish raster-based topsoil property map combining choropleth maps and point information
Geografisk Tidsskrift, Danish Journal of Geography 107(2):1–12, 2007 The Danish environmental authorities have posed a soil type dependent restriction on the application of nitrogen. The official Danish soil map is a choropleth topsoil map classifying the agricultural land into eight classes. The use of the soil map has shown that the maps have serious classification flaws. The objective of this work is to compile a continuous national topsoil te…
Short contribution
Archaeological sites dating to the Ertebolle period of the Mesolithic have been recorded below a thin layer of marine sands in a reclaimed bay on northern Falster Island in Denmark. The finds seemed randomly distributed throughout the bay; there was no obvious pattern related to the modern landscape. However, by coring through the veneer of marine sands and mapping the pattern of the underlying Late Quaternary deposits, the authors were able to r…
Role of landscape parameters in riverine run-off, and sediment and organic matter yield on Disko Island, West Greenland
Measurements of discharge and suspended sediment and organic matter yield from nine different drainage basins on the island Disko in central West Greenland were carried out in the period 19–30 July 1997. A series of landscape properties (glacier cover, altitude, slope, aspect and vegetation cover) were measured for each drainage basin from a digital elevation model and a satellite image. Principal Component Analysis and regression statistics have…

On identifying the most time-saving walking route in a trackless mountainous terrain
A procedure is presented to find the most efficient walking route to inspect 16 rain gauges within a mountainous location on the Faeroe Islands. Measured walking times on varying slopes and crossing shallow rivers were used as inputs to establish a friction-based cost surface. Subsequently, a cost path analysis led to identification of a web of least-cost paths between the locations. Finally, the most time-saving route to visit all rain gauges in…
Towards a second generation digital elevation model for Denmark
Geografisk Tidsskrift, Danish Journal of Geography 99: 27–34, 1999 In 1985 the first national digital elevation model (DEM) of Denmark was produced, based on 5 m contours from topographical maps with a scale of 1:50,000. Though improved during the last decade, it is obvious that the quality of this model is not sufficient for environmental assessments related to e.g. studies of overland flows. The Danish National Survey and Cadastre, which is res…
Generation of a digital elevation model of Mols Bjerge, Denmark, and georeferencing of airborne scanner data
Geografisk Tidsskrift, Danish Journal of Geography 99: 35–45, 1999 The study compares various digital elevation models (DEM) and georeferencing methods for the purpose of orthorectifying airborne scanner data. The study was performed using topographical maps on the scale of 1:25,000 produced by the Danish National Survey and Cadastre and a Compact Airborne Spectrographic Imager (casi) image. The study area, was a topographically complex area in D…

The Use of Geographical Information Systems in the Planning Phase of a Fieldwork Project
Bai Strom, Thomas: The Use of Geographical Information Systems in the Planning Phase of a Fieldwork Project. Geografisk Tidsskrift 92:75–79. Copenhagen 1992. This article will demonstrate how a digital elevation model for a catchment area on the Faeroe Islands has been used in a geographical information system to select suitable sites for rain gauge mounting in order to reflect the orographic conditions. Furthermore, it will demonstrate how to id…
