Program collects data of fresh water phytoplankton, phytobenthos, aquatic invertebrates, fish and plants. It intends to reach sufficient data to assess biological quality of water bodies and monitor their change in time. The program is designed to answer the needs of ecological classification determined by Water Framework Directive. The program is managed by Finnish Environment Institute (SYKE), Regional centres for economic development, transport and the environment (ELY-centre) and Natural Resource Institute Finland. Observations are done in the monitoring of water quality network and in specially designed network for anthropogenically eutrophicated lakes and rivers. Monitoring frequency varies between the locations and measured elements.
The purpose of the BioBasis programme is to monitor basic qualitative and quantitative elements of biodiversity in the terrestrial ecosystems at Zackenberg in Northeast Greenland. The programme provides data on typical High Arctic species and processes that can be expected to react on year to year variation in climate as well as long-term climate change. It includes 30 variables of terrestrial and limnic plant, arthropod, bird and mammal dynamics in the Zackenberg valley.
Annual measurements of physical, chemical, and biological variables are taken in small to medium sized, mostly minimally disturbed lakes, situated across the country. Of the 108 lakes that are part of the Trend Station Lake monitoring programme, 20 are situated in AMAP area. The main aim of the monitoring programme is to document long-term changes related to global or regional change and human-generated stressors. To complement the Trend Station Lake monitoring programme, national lake surveys provide spatial data needed to determine regional patterns, and coupled with time-series data, changes in surface water quality. The National Lake Survey (the Surveillance Stations, re-sampled stations) programme for lake water quality, started in 2007 and results in data of all Swedish lake conditions. Each year some 800 new lakes are sampled to determine chemical and physical conditions; lakes are resampled at 6 year intevals. 4824 lakes are sampled in the country during a six-year sampling cycle, with 1270 situated in AMAP area. The variables included in the Trend Station Lake monitoring programme include water chemistry, fish, phytoplankton, macrophytes, zooplankton, and benthic invertebrates, whilst the National Lake Survey is focused solely on chemical and physical parameters.
TOV is based on integrated monitoring where species and ecosystems are seen in context, providing better opportunities to interpret the results. TOV areas include seven monitoring sites in Boreal birch forest, all nature-protected areas. Lund in the south to Dividalen north is monitoring; lichen and algae on trees, ground vegetation, rodents, passerine birds, grouse, Gyrfalcon and Golden Eagle. There are also 10 Boreal spruce forest areas monitored, only for ground vegetation. The range of areas reflects both climate variability and differences in impacts from long-range pollutants throughout the country.
Monitoring of flora and vegetation includes records of species and species composition of ground vegetation and mosses, lichens and fungi on tree trunks. Fauna monitoring includes population and reproduction monitoring for species which may indicate effects of long-range transboundary air pollution, and population monitoring of key species. In addition, a nationwide survey of selected variables, prevalence of lichen and algae on trees, as well as contaminants in wildlife species and eggs from birds of prey. Observed changes are considered in relation to the influence of anthropogenic factors.
Multidisciplinary investigations at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN are carried out at a total of 21 permanent sampling sites in water depths ranging between 250 and 5,500 m. From the outset, repeated sampling in the water column and at the deep seafloor during regular expeditions in summer months was complemented by continuous year-round sampling and sensing using autonomous instruments in anchored devices (i.e., moorings and free-falling systems). The central HAUSGARTEN station at 2,500 m water depth in the eastern Fram Strait serves as an experimental area for unique biological in situ experiments at the seafloor, simulating various scenarios in changing environmental settings. Time-series studies at the HAUSGARTEN observatory, covering almost all compartments of the marine ecosystem, provide insights into processes and dynamics within an arctic marine ecosystem and act as a baseline for further investigations of ongoing changes in the Fram Strait. Long-term observations at HAUSGARTEN will significantly contribute to the global community’s efforts to understand variations in ecosystem structure and functioning on seasonal to decadal time-scales in an overall warming Arctic and will allow for improved future predictions under different climate scenarios.
The project, Arctic and Alpine Stream Ecosystem Research (AASER), started within EU’s Climate & Environment Programme and now continues with national funding, primarily Norway, Italy and Austria. The objective is to study dynamics and processes in rivers systems in Arctic and Alpine regions. Emphasis is given to the relationships between benthic invertebrates and environmental variables, especially in glacier-fed systems and in relation to climate change scenarios. On Svalbard research is concentrated around Ny Ålesund, particularly Bayelva and Londonelva. In 2004 the focus will be on the use to stable isotopes to detect transfer processes within and between ecosystems.
The aim is to observe long term effects of land use practices on waters. Monitoring concerns specific locations, where diffuse loads of nutrient or pollutants of agricultural and forestry origin poses a significant risk on water quality. Monitoring includes biological and physio-chemical elements. The program is part of monitoring according to the Water Framework Directive. It is coordinated by Finnish Environmental Institute (SYKE).
Project aims to observe the state of algal blooming in summer through a network of observation sites. Monitoring is coordinated by Finnish Environmental Institute and implemented by the regional centres for environment together with private observing personnel.
The objective of our work with arctic terrestrial plants and with algae is to study the range of climate adaptation as is expressed in special ultrastructure of cells and tissues, in photosynthetic metabolism, in antioxidative and sun screen compounds under a cold and reduced PAR / UV-B environment (climate different to alpine conditions). This is a comparison of ecophysiological processes already worked out mainly from high alpine plants, which live periodically under stronger cold and under different light regimes, especially higher UV-B and PAR irradiation. We want to find out, whether adaptations found in some alpine organisms occur similarly in polar forms.
The Nuuk-Basic project aims to establish a climate monitoring programme on the westcoast of Greenland. During two workshops, one being in Nuuk with field survey, framework for a future climate monitoring programme will be established. The programme builds on the concept and institutions already performing climate monitoring in NE-Greenland through ZERO (Zackenberg Ecological Research Operations).
The ZERO database contains all validated data from the Zackenberg Ecological Research Operations Basic Programmes (ClimateBasis, GeoBasis, BioBasis and MarinBasis). The purpose of the project is to run and update the database with new validated data after each succesfull field season. Data will be available for the public through the Zackenberg homepage linking to the NERI database. The yearly update is dependent on that each Basis programme delivers validated data in the proscribed format.
This project investigates how solar UV radiation affects planktonic food webs in the Arctic by changing the nutritional quality of the lower trophic levels. UV radiation has been documented to lead to oxidation of poly-unsaturated fatty acids (PUFAs) in phytoplankton. These PUFAs cannot be synthesized de novo by zooplankton, but are key molecules for the marine pelagic food web. A combined approach was chosen with both sampling of field data (physical as well as biological) and experiments which were carried out during two field seasons in Ny Ålesund in 2003 (april/may) and 2004 (may/june). In 2004, the main part of the field work consisted of an outdoor experiment where phytoplankton was exposed to different irradiation regimes, using the natural sunlight. Algae from all different treatments were used for feeding zooplankton in order to trace the transfer of irradiation-induced changes of the fatty acid composition in phytoplankton to the next trophic level. A number of additional parameters will be analysed as well, combined with the results of an extensive measurement series of both PAR- and UV light. The experiment was carried out on the old pier (Gamle Kaia), while the laboratory part took place in the Italian station ‘Dirigibile Italia’.
Work program: Grab air samples will be collected in sampling sites not influenced by local emission sources for the determination of chlorofluorocarbons and of hydrogenated halocarbons. A 15 days sampling campaign is scheduled. Samples will be analysed in our Institution by using the analytical methodology here described and results obtained will be evaluated and compared with data obtained, by using the same analytical methodology, analysing air samples collected in other remote and semi remote sites. For the analysis of the hydrogenated halocarbon degradation products snow and water samples will be collected as well, according to the different season of the year. The collected samples will be then derivatized and analysed in our Institution for the evaluation of the presence of such compounds in remote areas.
The main objective was to investigate the importance of the sediment as a nutrient source for blooms of nuiscance filamentous algae. Nutrient fluxes from the sediment were hypothesised to be of greater importance in maintaining algal biomass than were nutrients originating from the overlying water column. We aimed to assess the relative importance of algal mats on sediment geochemistry and nutrient release under stillwater and controlled flow conditions. Using nutrient fluxes as a surrogate for ecosystem function, we wished to investigate the role of species richness in maintaining the integrity of nutrient diagenesis. In this context, it is not necessarily the number of species that is important in maintaining nutrient supply to algal blooms, but the contribution individual species make to mediate nutrient release.
The aim of our work was to study the occurrence of inorganic carbon pumps in the cell membrane and their importance in the supply of C for photosynthesis in different macrophyte species. This was performed by checking and comparing responses of several green, brown and, especially, red marine macroalgae species under CO2 disequilibrium conditions in the presence of buffer and/or inhibitors of carbon uptake. In addition, the effect of the different treatments was also checked in the marine phanerogam Zostera marina.
Since nearly all microalgae are associated with bacteria and some harbor intracellular bacteria, it is most likely that these bacteria are involved in the development or termination of natural occurring plankton assemblages. The diversity and development of associated bacteria in microalgae cultures and during phytoplankton succession will be described by molecular analysis of the bacterial community structure and by phylogenetic analysis of involved microorganisms.
To study the organisms involved in phytoplankton succession and the Key factors involved. This includes Bacteria-Algae, Algae-zooplankton and Zooplankton-Fish interactions. Aspects such as algal-grazer defence mechanisms and digestability of alage are core topics.
Effects of UV-B radiation on microbial communities in Kongsfjorden in relation to metal and dissolved organic matter availabillity.
The aim of this project is to investigate natural products from polar macroalgae. As arctic waters represent an extreme habitat, formation of secondary metabolites is limited - besides other factors - by light conditions. Therefore, the influence of light, particularly different photon fluence rates and UV radiation, on secondary metabolism and on regulation of associated genes will be studied.
As a result of the increasing atmospheric CO2 levels and other greenhose gases due to anthropogenic activities, global and water temperature is rising. The objectives of our project might be summarized as follows: I. To measure the activity of the enzymatic systems involved in carbon, nitrogen and phosphorus uptake (carbonic anhydrase, nitrate reductase and alkaline phosphatase) in selected macroalgae. To assess the optimal concentration of inorganic nitrogen and phosphorus for growth and photosynthesis. To study the total concentration of carbon and nitrogen metabolites in the macroalgae (proteins, total carbohydrates, and lipids) in order to define the possible existence of nutrient limitation. II. To simulate the conditions of climate change, represented as CO2 enrichment and increasing UV radiation, on the activity of carbon, nitrogen and phosphorus uptake mechanisms. III. To screen the activity of the enzymatic systems previously detailed in macroalgae from the Konjsfjord, in order to know their nutritional state.
