The International Panel on Climate Change (IPCC) has very recently revised the prediction of global average temperature increase during the next century from 1.0-3.5 to 1.4-5.8 K. The increase in the upper limit of the prediction is largely due to the role of aerosols in the climate of the Earth: it is believed that reduction of pollution will result in reduced direct and indirect (via clouds) scattering of sunlight back to the space. However, as can be seen from the large uncertainty of the estimated temperature increase, not enough is known about the role of natural and anthropogenic aerosols in climate processes. This is also reflected in the Key Action 2, under the RTD priority 2.1.1, calling for ”… quantification and prediction of … concentration of … aerosols, in particular the fine fraction of particles and their precursors”. The concentration of aerosols is controlled by their sources and sinks, and thus the prediction of particle concentration requires the quantification of aerosol source terms. The main objective of QUEST is to quantify the number of new secondary aerosol particles formed through homogeneous nucleation in the European boundary layer, and the relative contributions of natural and anthropogenic sources. The role of homogeneous nucleation in the formation of new atmospheric particles was realized in the 1990s, and considerable effort has been devoted to studies of aerosol formation in various parts of the Globe. The longest continuous data series of nucleation events has been obtained at a forest field station in Finland, where aerosol size distributions between 3 and 150 nm in diameter have been recorded in 10 minute intervals since the beginning of 1996 . Nucleation events occur in this rather clean Boreal area roughly 50-60 times per year, the highest event frequency taking place in the spring months (March-May). The concentration of new particles per cc of air formed during one event varies between roughly 100-10 000. Taking the average number to be one thousand, and assuming that the nucleation takes place in a well mixed boundary layer having a height of 1000 m, it can be estimated that the aerosol source term in the Boreal forest area is on the order of 51013 m-2 per year. This is on the same order as the global aerosol yield estimated from primary emissions . The number given here is very crude as we can at present only guess the vertical extent of the nucleation zone; however, it clearly shows that homogeneous nucleation events influence atmospheric particle concentrations at least at regional scales, and possibly also globally. Many features of the Boreal nucleation events have been revealed thus far. Necessary (but not sufficient) conditions include sunny weather, vertical mixing of air in the morning (prior to the detection of the event) , and a treshold value of a quantity that depends on radiation intensity (vapor source) and pre-existing aerosol size distribution (vapor sink) . The springtime events always seem to take place in Polar or Arctic air masses , but so far it is unclear whether the meteorology is similar during other seasons. Aerosol flux measurements  indicate that the particles are formed aloft, but the vertical extent of the nucleation layer is unknown. However, there is clear evidence from simultaneous measurements at various locations, that the horizontal extent of the areas in which the nucleation takes place can be hundreds and in some cases even thousands of kilometers . No direct correlation of nucleation events with SO2 concentrations has been found; however the product of SO2 concentration, ammonia concentration, and calculated OH concentration correlates with the events (personal communication). These results hint that the recently suggested ternary sulfuric acid-ammonia-water nucleation mechanism of small clusters, followed by the growth of the clusters due to condensation of other (possibly organic) vapors , may be operational in the Boreal forest area. Furthermore, there is experimental evidence that nucleation event particles in the 4-5 nm range are soluble in butanol (working fluid of condensation particle counters), which indicates organic composition. However, the confirmation of the ternary nucleation hypothesis requires simultaneous measurements of sulfuric acid vapor and ammonia, and further studies of the composition of the nucleated particles. Furthermore, to facilitate large-scale modelling studies, the vertical extent of the nucleation events, as well as the meteorological conditions during non-springtime events have to be investigated. Measurements of nucleation events at a more Central European location indicate that SO2 levels increase during the majority of nucleation events . It can be hypothesized that a part of observed nucleation events (minority in Central Europe, majority in the Boreal area) are ”natural” and a part are affected (or even caused) by pollution (majority in Central Europe, minority in the Boreal area). The confirmation of this hypothesis and implementation of the pollution type nucleation mechanism into a large-scale model requires carefully designed measurements from a location which is preferably Southern European as there is very little available nucleation data from this area. One of the few observations of new particles in Southern Europe  is from the Italian site where we plan to study the frequency, meteorology, vertical extent, and chemical precursors of nucleation events. Another type of nucleation events has been observed all along the western coast of Europe and have been studied more particularly at the west coast of Ireland . These events, which have a duration of the order of 4 hours and up to 8 hours, occur almost daily around low tide and under conditions of solar radiation, indicating photochemical source. Incredibly, the peak new particle concentrations often exceed 106 cm-3, making this the strongest natural source region of atmospheric particles. The exact chemical mechanisms leading to the production of coastal particles still remains an open question. As in other environments, there appears to be sufficient sulphuric acid vapour to participate in ternary nucleation with ammonia and water, however, there is insufficient sulphuric acid to grow these particles to detectable sizes . The most probable chemical species involved in the production or growth of these particles is Iodine, or an Iodine Oxide, produced photochemically from biogenic halocarbon emissions . The production of particles from the photolysis of CH2I2 in the presence of ozone has been confirmed by recent smog chamber experiments . While the concentration of new particles in this environment is extraordinarily high, its impact on background particle and CCN contribution remains unclear and needs to be quantified. A limited single study  has shown that the coastal aerosol plume is detectable up to several hunderds of km downwind and that the new coastal particles readily grow into CCN sizes (larger than 100 nm). An intensive campaign at the coast of Ireland will quantify the flux of both biogenic halocarbon precursor gases and the yield of new, and radiatively-active particles in the European coastal boundary layer. The objective of QUEST is to determine the source strength of new particle formation in the three above mentioned cases. The specific objectives are: 1) To fill in gaps that exist in the understanding of chemical and physical pathways leading to homogeneous nucleation of new aerosol particles; 2) To understand the meteorological conditions required for the events to take place and to be able to predict the horizontal and vertical extent of the events; 3) To implement parametrized representations of the nucleation mechanisms, based on the information from 1) and 2), to an European scale model in order to determine the source strength of homogeneous nucleation of aerosol particles in the European boundary layer.
This study will be part of the EU project NTAP. The overall objective of NTAP is to provide a unified conceptual framework for nutrient dynamics as modulated by the interaction of turbulence and plankton and to use this information to aid in implementing and modifying legislation on coastal water quality and management. Specifically, the objectives are a) to build a database on turbulence effects by gathering existing scattered data, b) to produce experimental data on key organisms, interactions and mass transfer rates, c) to develop a sensor for laboratory measurement of small-scale turbulence, and d) to produce a dynamical model at community level with exploratory and predictive capabilities. The present project will fit within Objective b), and will complement other NTAP experimental studies with cultures and natural communities that are being carried out in different European laboratories. The results derived from this project will also be valuable to test and calibrate the model developed within Objective d).
Four-week mesocosm study with the following objectives: - to identify environmental and biotic factors in control of the production, chemistry and fate of exportable DOM in a coastal environment - to follow how DIN and DIP are transformed to DON and DOP and to measure their mineralisation - to analyse the optical properties of new DOM and to measure how radiation might change the optical properties - to validate current community-nutrient models for the marine system with particular emphasis on the mechanisms regulating shifts between carbon- and mineral nutrient limitation of bacterial growth rates, - to produce experimental data for further development and modification of the plankton community-nutrient model and – to incorporate DON and DOP into the present community-nutrient model.
Aim of the project is to develop a cost-effective long-term European observation system for halocarbons and to predict and assess impacts of the halocarbons on the climate and on the ozone layer. Beside the routine observations within the NDSC it is planned to perform with FTIR (Fourier Transform Infrared Spectroscopy) absorption measurements of CFCs (e.g. SF6, CCl2F2, CHF2Cl) and related species on much more observation days.
The active layer, the annually freezing and thawing upper ground in permafrost areas, is of pivotal importance. The moisture and heat transfer characteristics of this layer also determine the boundary layer interactions of the underlying permafrost and the atmosphere and are therefore important parameters input for geothermal or climate modeling. Finally, changes in the characteristics of the permafrost and permafrost related processes may be used as indicators of global ecological change provided the system permafrost-active layer-atmosphere is understood sufficiently well. The dynamics of permafrost soils is measured with high accuracy and high temporal resolution at our two sites close to Ny-Ålesund, Svalbard. Using these continuous data we quantify energy balance components and deduce heat transfer processes such as conductive heat flux, generation of heat from phase transitions, and migration of water vapor.

- To support the further development of a geocryological database for the Usa Basin (East-European Russian Arctic), including key characteristics of permafrost such as distribution, coverage, temperature, active layer, etc. - To create GIS-based permafrost maps at the scale of 1:1,000,000 for the entire Usa Basin and at 1:100,000 for selected key sites. - To reconstruct the history of permafrost dynamics at key sites in the region over the last thousands of years using palaeoecological analysis and radiocarbon dating of peat deposits, and over the last few decades using remote sensing imagery and/or monitoring (base case scenario). - To predict permafrost dynamics at key sites in the region under future conditions of climate change (20-100 yrs), using a 1-dimensional permafrost model (future global change scenario). - To assess the effects of permafrost dynamics under base case and global change scenarios on urban, industrial and transportation infrastructure in the Usa Basin. Research activities Based on several representative sites, late Holocene permafrost dynamics will be characterized using palaeoecological techniques. Variability in permafrost conditions over the last few decades will be studied based on the available data from long-term monitoring station records and from a time series of remote sensing images (optional). Mathematical modelling of permafrost dynamics will be carried out for at least two sites and a forecast of permafrost degradation in the area under anticipated climate warming will be developed. The likely effects of permafrost degradation upon regional infrastructure (inhabited localities, heat and power engineering, coal and ore mines, oil and gas extracting complex, pipelines and railways) will be analyzed using a GIS approach. GIS data layers on permafrost dynamics and infrastructure will be compared in order to delimitate high risk areas based on existing infrastructure and anticipated permafrost degradation. Hereafter, the created GIS may serve as a basis for more detailed forecasting of permafrost dynamics under both natural and anthropogenic climate changes in lowland and alpine areas of the East-European Russian Arctic.
The aim of this project is to assess the deposition of HM/POP over Europe and to evaluate models. Within the framework of UN-ECE, EMEP Meteorological Synthesising Centre-East (MSC-E Moscow) organised in co-operation with RIVM, a model intercomparison for operational transport models on HM in 1995. In this intercomparison the RIVM will participate with the TREND-model. Results of the intercomparison will also be reported to the OSPAR commission. A model comparison for POPs will follow later. The RIVM/EUROS model is extended with soil and surface water modules in order to improve the description of the exchange process of POPs (deposition and re-emission). With the model, long-term averages of the deposition and accumulatation of POPs are described and scenario-studies can be carried out. In the first instance, Lindane and B(a)P will be taken as examples of POPs dominantly present respectively in the gas phase and attached to particles. When emissions are available the calculations are extended to other POPs.
In 1990, the Directorate for Nature Management (DN) established an area for integrated monitoring within Børgefjell National Park, Røyrvik, N Trøndelag. Studies of vegetation-environment relationships in the area was performed by NINA. The area includes both subalpine birch forest and low alpine heath. The new established vegetation investigation included all together 80 different species. This material was processed numerically by using multivariate methods. Indirect gradient analyses were performed using Detrended Correspondence Analysis (DCA) and Local Nonmetric Multidimentional Scaling (LNMDS). Direct gradient analyses were performed by using rescaled hybrid Canonical Correspondence Analysis (CCA). Non-parametric correlation analyses, Kendall’s , were performed between environmental parameters and DCA axis values. The results of the numerical and statistical processing were used partly to provide a description of the vegetational structure in the material and partly to quantify how much each ecological parameters contributed to determination of vegetational structure. This work shows the species distribution along various complex gradients; moisture, nutrient conditions, light etc. The investigation is primarily designed to study vegetation dynamics along these gradients and whether changes in the number of species can be related to changes in physical, biotic and, not least, chemical parameters. Variance analysis was performed to assess to what extent the sample plots tends move in a determined direction from 1990 to 1995. The variation between the years were not significant along the primary complex gradients, but there were a significant displacement of species along the following gradients. The most important species were: Vaccinium vitis-idaea, Melampyrum sylvaticum and Hylocomium splendens), which showed an increase and some cryptogams like Brachythecium reflexum, B. salebrosum and Cladonia ecmocyna which declined.

In 1994, analyses of sediments and fish from Lake Ellasjøen on Bear Island revealed a surprising scenario. The analytical results indicated some of the highest values of the contaminants PCB and DDT in freshwater sediments and fish ever found in the Arctic. The 1994 results were based on limited amounts of samples. During 1996 and 1997 there were carried out new sampling and analyses of several samples. These results verify the results found in 1994. Since the POP-patterns found deviate considerably from the typical patterns expected for local contamination, no local source can be assumed to be responsible for the high POP values found. Thus, the questions that need to be addressed include the source of these contaminants, the transport pathways that deliver these contaminants to this site, total deposition and finally contaminant fate including biological uptake and effects. Previous investigations from the early 80’s on high volume air samples carried out at Bear Island revealed several long-range transport episodes from Eastern Europe. The overall objective of this project is to contribute significant new information to the understanding of contaminant pathways in the Arctic hydrosphere and to provide a better understanding of contaminant focusing in a sensitive polar environment. This will be accomplished through the development of a comprehensive mass balance study of the atmospheric loadings of PCBs and other contaminants to the Lake Ellasjøen watershed to determine the seasonal importance of atmospheric deposition on a remote polar island. Further, effort will be directed at assessing the relative importance of various source regions of contaminants to the island through an evaluation of contaminant signatures and back trajectories of pollution events.
