  • WP5 - Groundwater Dynamics
    00 am Forest and Landscape College Airborne Campaigns Weather Radar Models Soil Moisture Network Remote Sensing Geophysics Isotopes Cosmic ray Greenhouse Gasses WP5 Groundwater Dynamics Objectives 1 To develop appropriate hydrogeological and geophysical methods for locating aquifer systems at outflow boundaries and quantifying the diffuse submarine groundwater discharge to Ringkøbing Fjord and the North Sea 2 To map the freshwater saltwater interface in the eastern part of the survey area 3 To integrate the information and data obtained from hydrological and geophysical investigations into a numerical groundwater model Work content Task 1 SkyTEM survey A SkyTEM survey has been conducted in the western side of the catchment over Ringkøbing lagoon revealing extremely detailed information on the hydrogeological setting by application of novel methodology developed at Aarhus University The survey provides a highly detailed picture of the salinity distribution in the area showing that the hydrological setting is to a large degree governed by a heterogenous geology The results of the survey is currently used as the basis for further hydrological studies of the area as well as refining existing hydrological models Task 2 Mapping of saltwater freshwater dynamics in Ringkøbing Fjord Measurements on the shallow groundwater system below the Ringkøbing

  • WP6 - Greenhouse Gasses
    Campaigns Weather Radar Models Soil Moisture Network Remote Sensing Geophysics Isotopes Cosmic ray Greenhouse Gasses WP6 Greenhouse Gasses Objectives 1 To measure the relevant greenhouse gas fluxes above three different surface types in the catchment 2 To identify the main driving factors for the exchange of greenhouse gases between the land surface and the atmosphere Work content Task 1 Eddy flux measurements of greenhouse gases Sonic anemometers and infrared gas analysers for the detection of H2O and CO2 have been installed permanently at all 3 sites in collaboration with WP2 The meadow site at Skjern Enge has been equipped with an ICOS integrated cavity output spectroscopy laser to detect CH4 At the agricultural site an Off Axis ICOS LGR laser gas analyser is measuring N2O and CO The eddy covariance technique is applied to calculate the fluxes of all greenhouse gases The high frequency raw data is processed using the Alteddy software Wageningen University and Research Centre The Netherlands Task 2 Partitioning of the CO2 fluxes At the forest site the vertical within canopy CO2 profile is monitored and 4 soil respiration chambers have been installed for continuous measurements of the CO2 flux between the soil and the canopy air Leaf level photosynthesis chambers will be applied on occasion at all three sites Meteorological sensors measuring the microclimate in and above the vegetation accompany the investigations Task 3 Feedbacks between carbon and water cycle The exchange rates of H2O and CO2 between the vegetation and the atmosphere are closely linked through the action of the stomata in the leaves Therefore the study aims to develop a robust description of the stomatal resistance of the three vegetation types and its response to environmental factors The water use efficiency being the ratio between the CO2 uptake and the water loss is monitored
