1. Measurements of climate-influencing substances on Svalbard

National Environmental Monitoring in Sweden in the "Air" programme. The objective of the project is to follow climate-changing gases and particles and which effects they could have on the climate of earth. To understand and assess the human effect on the climate, regionally and globally, the atmospheric aerosols and greenhouse gases are monitored. The project aims follow: (i) detecting long-term trends in the carbon dioxide level, as well as trends in the amount or composition of aerosols in the background atmosphere; (ii) provide a basis to study the processes that control the aerosol life cycle from their formation through aging and transformation, until being removed from the atmosphere; (iii) provide a basis to study the processes (sources, sinks, and transport pathways) that control the level of carbon dioxide in the atmosphere; (iv) contribute to the global network of stations that perform continous measurements of atmospheric particles and trace gases to determine their effect on the earths radiation balance and interaction with clouds and climate.

2. Radnett – a national network for monitoring radioactivity in the environment

The Norwegian Radiation Protection Authority is responsible for a nationwide network of 33 stations that continuously measure background radiation levels. The network was established in the years following the Chernobyl accident in 1986, and was upgraded to a new and modern network in the period 2006-2008. Additional stations were added in 2009. The purpose of the monitoring network is to provide an early warning if radioactive emissions reach Norway.

8. Long-term effects of offshore discharges on cold water zooplankton: establishing a test system for chronic exposure to offshore discharges

During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.

10. Differential Optical Absorption Spectrometer

The DOAS instrument consists of grating spectrometer covering the visible and near ultraviolet spectral region. Zenith-scattered sunlight is collected by simple one-lens telescopes and fed via optical fiber bundles into the spectrometers, where atmospheric absorption spectra are obtained. The instrument runs automatically. Total column densities of the stratospheric trace species ozone, NO2, BrO, and OClO are retrieved from the spectra using the DOAS algorithm. These are species that play a major role in ozone chemistry, either by themselves in ozone destruction (BrO) or as indicators of chlorine activation/deactivation (OClO). The chemistry and dynamics of ozone destruction is investigated, e.g. with respect to the location of the polar vortex during the winter. The instrument is also useful for detection of polar stratospheric clouds using the zenith-sky colour index method.

16. Stratosphere-mesosphere intercomparison of ozone profil

During the past years, atmospheric research in high latitudes has been focussed on processes causing ozone loss in the polar winter lower stratosphere1). Recent research efforts also dealt with regions up to the lower mesosphere, and studied the effects of charged particle precipitation on NO and ozone2)-5). However, the measurement techniques and hence the database for studying such processes in this altitude range are very limited. The Airborne SUbmillimeter Radiometer ASUR6),7) of the Institute of Environmental Physics of the University of Bremen has recently been equipped with a high-resolution spectrometer that will enable the retrieval of vertical profiles of ozone up to an altitude of about 65 - 70 km. Its measurement capabilities comprise also several other species of interest, especially NO. This makes the measurement technique particularly suitable for upper stratospheric/lower mesospheric studies. The lidar at ALOMAR is capable of measuring highly resolved vertical profiles of ozone up to an altitude of 60 km, thus giving the rare opportunity for intercomparison and validation studies in an altitude range reaching from the lower stratosphere to the lower mesosphere. Therefore we propose to perform simultaneous ozone measurements of the ASUR instrument with the ALOMAR lidar, supported by launches of ozone sondes.

17. Ground-based observations of noctilucent clouds With the shortest possible wavelength (308 nm)

Noctilucent clouds (NLC) remain a fascinating phenomenon of the upper atmosphere to study. The questions about the typical particle density and particle size distribution within a NLC are very prominent ones, to which a number of answers have been given, though some of the answers contradict each other. The parameters of particle size distributions can be derived from groundbased lidar measurements of the spectral dependence of the volume backscatter coefficient of an NLC. Such studies have been performed during a number of NLC events by e.g. the ALOMAR Rayleigh/Mie/Raman (RMR) lidar (von Cossart et al., GRL, 26, 1513, 1999). A drawback of these experiments is the wavelength limitation of the RMR lidar, the shortest wavelength of which is 355 nm. At this wavelength, the sensitivity of the lidar to particles with sizes smaller than, say, 25 nm is minimal. Because a considerable part of the entire particle population may have sizes below that threshold, a lingering question remains whether or not this drawback matters for typical NLC distributions. Using the ALOMAR ozone lidar, a measurement of the NLC volume backscatter coefficient at 308 nm becomes possible. Due to the l-4 -dependence of the backscatter coefficients, the latter are almost a factor of 2 larger at this wavelength than at 355 nm. For this reason and in order to gain a fourth wavelength to the spectral distribution, we aim at using the ozone lidar for the outlined project.

18. Simultaneous multi-instrumental measurements of temperatures, waves and PSCs in the polar winter atmosphere on both sides of the Scandinavian mountains

Waves play a major role for the momentum and energy transport in the middle atmosphere [Fritts and van Zandt, 1993] by modifying the local temperature field as well as the general circulation when the waves reach the saturation level and break [Holton, 1983; Fritts, 1984]. The MACWAVE rocket campaign is investigating the wave field in polar latitudes during summer and winter. To learn more about the horizontal structure of the wave field, it is important to measure at more than one station. For the monitoring of the vertical transport by the waves, measurements over a large height range are necessary. The combination of lidars, radiosondes and falling spheres will cover the region from the ground up to approximately 105 km. When comparing data, it is important to take into account the different measurement principles and integration times. The rocket will show small scale variations whereas the lidar permits a continuous monitoring of the temperature and wave situation

20. Monitoring of arctic foxes (Alopex lagopus) in the Kongsfjord area

To evaluate temporal variation in arctic fox numbers and their food resourses in the Kongsfjorden area. The number of foxes captured per 100 trap-days are used as an index of fox density termed "Fox Capture Index". The observations of denning activity i.e. observation of number of arctic fox litters and litter size at den are termed "Fox Den Index" as a second index of fox abundance. A third index is termed "Fox Observation Index". This index is based on both observations of adult foxes seen away from breeding dens pr 100 h field work and reports on request from scientists and local people on observations of adult foxes during summer. In addition, reports on observation of fox tracks in the study area were collected in 1990-2001 as a fourth index, which were called "Fox Track Index". The field census are conducted for 10 days starting at the end of June. All dead foxes in the area should be collected.
