At the Ministry of the Environment, we find it important to use INSPIRE wherever this makes sense. This means that the implementation of the Directive does not take place simply because we as an EU member state are under an obligation to implement it. We do this primarily because INSPIRE provides us with a good, extensive and, not least, thoroughly researched methodologically sound framework that can support our own (i.e. Denmark's) efforts in the construction of an infrastructure for spatial information. In this effort, we aim to make sure that INSPIRE forms the foundation for Danish digital governance. This brings INSPIRE's data sets and services into use in the concrete handling of tasks. The implementation of INSPIRE calls for control and coordination, as we focus on a good relation to the digital administration, and in particular the administration of the environmental and nature area. In other words, governance. This article gives an account of the Danish Geodata Agency's role in connection with the implementation of INSPIRE. It also provides examples of implementation projects in the Ministry of the Environment that are based on spatial data sets.

I Miljøministeriet lægger vi vægt på at bruge INSPIRE, hvor det giver mening. Det vil sige, at implementeringen af direktivet ikke sker bare, fordi vi som EU-medlemsland er forpligtiget til at implementere det. Vi gør det fortrinsvis, fordi vi med INSPIRE får et godt, omfangsrigt og ikke mindst gennemarbejdet metode- og rammeværk, som kan understøtte vores egen (dvs. nationale) indsats i opbygningen af en infrastruktur for geografisk information. I denne indsats tilstræber vi, at INSPIRE udgør fundamentet i dendanske digitale forvaltning. Herved bringes INSPIREs datasæt og tjenester i anvendelse i den konkrete opgavevaretagelse. Implementeringen af INSPIRE kræver styring og koordinering, da vi sætter fokus på sammenhæng til dendigitale forvaltning og særligt forvaltningen af miljø- og naturområdet. Altså governance. Denne artikel redegør for Geodatastyrelsens rolle i forbindelse med implementeringen af INSPIRE samt kommer med eksempler på implementeringsprojekteri miljøministeriet, som bygger på geografiske datasæt.

Inputs of dissolved carbon, nitrogen, and phosphorus were assessed for an estuary and its catchment (Horsens, Denmark). Seasonal patterns in the concentrations of DOM in the freshwater supply to the estuary differed depending on the soil and drainage characteristics of the area. In streams draining more natural areas the, patterns observed were largely driven by seasonal temperature fluctuations. The material exported from agricultural areas was more variable and largely controlled by precipitation events. Positive exponential relationships were found between the nitrogen and phosphorus loading, and the percentage of catchment area used for agriculture. Colored DOM (CDOM) loading measurements were found to be a good predictor of dissolved organic carbon (DOC) loading across the different subcatchments, offering a rapid and inexpensive alternative of operationally monitoring DOC export. For all the dissolved nutrient inputs to the estuary, dissolved inorganic nitrogen (DIN) and dissolved organic phosphorus dominated the loadings. Although 81% of the nitrogen annually supplied to the estuary was DIN, 83% of the nitrogen exported from the estuary was dissolved organic nitrogen (DON). Results show that increasing the area of the catchment covered by forest and natural pastures would have a positive effect on the trophic status of the estuary, leading to a considerable decrease in the phosphorus loading and a shift in the nitrogen loading from DIN to DON. Such a change in land use would also increase the export of DOC and CDOM to the estuary having the potential to increase oxygen consumption and reduce the photic depth.

This paper presents data on physical conditions and carbon transport in a typical northeast Greenland fjord along with predictions of expected changes in the area due to climate change. The fjord has an average depth of 100 m; the maximum depth is 360 m, and a sill at a depth of 45 m is found at its entrance. Sea ice covers the fjord from early October to late July. The freshwater input to the fjord, occurring from June to September, is 1063x10(6) m(3) from the catchment area (3109 km(2)) and 440x10(6) m(3) from melting of sea ice. During the ice-free period this buoyancy input and mixing by wind and tides results in an estuarine circulation in which lighter low-salinity water is moved seaward above denser water from the Greenland Sea. The tidal amplitude is 0.8 to 1.5 m, and the transport of tides from the outer parts of the fjord to the inner parts is delayed less than 15 min due to low friction in the fjord system. During the ice-free period, a net carbon input of 15-50 t C d(-1) occurs in the outer region of the fjord due to transport from land and the adjacent Greenland Sea. A regional atmosphere-ocean model predicts a temperature increase of 6-8degreesC at the end of this century (2071-2100) that will lead to increase in freshwater runoff, thinning of the sea ice, and an increase in ice-free conditions from 2.5 mo to 4.7-5.3 mo in Young Sound. The increased freshwater input will greatly enhance the estuarine circulation and nutrient input to the fjord and is expected to increase biological productivity.
