21. Heavy Metal and Radionuclide Contaminants in Caribou

Objectives 1. To determine tissue residue levels of metals and radionuclides in caribou given its importance as a country food species. 2. To monitor contaminant exposure in caribou as a representative species of the terrestrial arctic ecosystem. 3. To examine metal speciation and isotopes ratios (uranium, thorium, strontium, titanium) which may provide insight into the source of contamination (anthropogenic vs. natural). 4.To provide information on temporal trends in radionuclide and metal levels in several caribou herds to determine whether levels are increasing, decreasing or remaining the same over time. 5. To determine the efficacy of international controls in reducing or eliminating pollutants entering the Canadian Arctic terrestrial ecosystem. Barren-ground caribou are found across northern Canada, and are a major component of the traditional diet in communities across the Northwest Territories (NWT) and Nunavut. Caribou are a good indicator species for terrestrial ecosystem contamination given their wide distribution across northern Canada, the simple air-lichen-caribou food chain, the existing baseline data set, and their importance as a country food species. Three (3) caribou herds from across the NWT and Nunavut have been selected as sentinel herds, with a different herd to be sampled each year to determine tissue residue levels and monitor temporal trends. Field collections will be conducted in cooperation with local Hunter’s and Trapper’s Organizations and/or local aboriginal organizations, utilizing local hunters in planning and conducting the field work. Samples will be tested for a wide range of environmental contaminants including 10 heavy metals and 7 radionuclides.

24. Assessment of spatial and temporal patterns of HCH isomers in the arctic environment

In order to assess the spatial and temporal patterns of the a-, b- and g-isomers of hexachlorocyclohexane (HCH) in the arctic biotic and abiotic environment, it is proposed that: (1) concentrations and ratios of HCH isomers be compared over time in air, water, seals, beluga, polar bears and seabirds to determine any shifts in isomeric ratios and how those shifts interrelate among the various media, and (2) concentrations and ratios of HCH isomers be compared spatially in the abiotic and biotic media and reasons for any patterns explored.

29. AMAP 2009 and 2010 core HM and POP programme Faroe Islands

The project is a continuation of the monitoring activities of the AMAP POPs and Heavy metals programme in marine, terrestrial and freshwater environments of the Faroe Islands. The aims of the programme is to establish data for timetrend and spatial assessments as well as providing data of importance in human health risk assessment on mercury and POPs. The programme incorporates analyses on pilot whale, cod, black guillemots from the marine environment, sheep and hare from the terrestrial environment and arctic char from the freshwater environment. The compounds analysed are "legacy" POPs and mercury, cadmium and selenium. In addition, a retrospective analyses of PFOS in pilot whale tissues going back as far as possible (ie.1986) is part of the project.

30. Occurence of "new" contaminants in marine biota in Greenland and the Faroe Islands

In addition to the persistent organic pollutants (POPs) analysed in former monitoring projects, other compounds of concern have been identified by the international community (e.g. OSPAR, AMAP), and analytical methods have been developed. These compounds include brominated flame retardants (BFRs), phthalates, polychlorinated naphthalenes (PCNs), perfluorooctane sulfonate (PFOS) and synthetic musk compounds. The aim of this project is to screen the marine environment of East and West Greenland and the Faroe Islands for these compounds. The analyses will be based on existing samples of pilot whale and fulmars from the Faroe Islands as well as marine sediments, shorthorn sculpins, ringed seals, minke whales from West Greenland and shorthorn sculpins, ringed seals and polar bears from East Greenland. As several trophic levels of the marine Arctic food chain are taken into account, the project will also result in information on the bioaccumulation of these compounds.

31. Long distance pollen transport in the Arctic: 1. Greenland

The submitted proposal aims to perform the monitoring of the pollen rain in the Greenland atmosphere by distinguishing the local pollen production, relatively low, from pollen grains originating from other Arctic areas. A regular monitoring of the atmospheric pollen content must be performed in order to evaluate the amount emitted and characterise the seasonality of the emission. A comparison with air mass trajectories must allow the modelling of long distance transport

32. Living in a spatially structured environment: evolutionary ecology of seabird-parasite interactions

The aim of this research program is to examine the response of animal populations to environmental variability at different spatial scales. We attempt to determine how individuals respond to the spatial heterogeneity of their environment, and what are the consequences of this response for the dynamics of subdivided populations. Specifically, we consider an ecological system involving biotic interactions at three levels: seabirds, their tick _Ixodes uriae_, and the microparasite _Borrelia burgdorferi_ sensu lato (Lyme disease agent). Colonies of seabirds represent discrete entities, within and among which parasites can circulate. Our previous work on this system in the norwegian arctic has enable us to show that (1) host dispersal can be affected by local conditions, (2) seabird tick populations are specialised among different host species, namely between sympatric kittiwakes _Rissa tridactyla_ and puffins _Fratercula arctica_, (3) in the kittiwake, females transmit antibodies against _Borrelia burgdorferi_ when their chicks have a high probability to be exposed to the tick vector. We propose to combine different approaches, incorporating field surveys and experiments and population genetic studies (of hosts and parasites), in order to better understand the role of local interactions and dispersal in the dynamics of such a system. The research program implies collaborations with researchers from other french groups, as well as with Canadian (Queen’s University) and Norwegian colleagues (from NINA and the University of Tromsø).

33. ENVISAT AO ID 130: Global study of inorganic chlorine and fluorine loading in the Earth’s atmosphere, based on correlative measurements by ENVISAT-1 and at 10 NDSC sites

The project aims at producing an ENVISAT-1 mission-long monitoring of the inorganic chlorine (Cly) and fluorine (Fy) loading in the Earth’s middle atmosphere, based on FTIR vertical column abundance measurements of the key related species HCl, ClONO2, HF and COF2 at 10 ground-based NDSC sites distributed worldwide. These Cly and Fy inventories will be completed with ClO and OClO measurements expected as Level-2 products from ENVISAT-1. The column abundances of the source gases CFC-12 and HCFC-22 will be used to place the stratospheric Cly and Fy evolution in perspective with the more complete sets of organic chlorinated and fluorinated compounds measured at the ground by the in situ networks NOAA-CMDL and AGAGE. The assimilation of the retrieved geophysical data bases will be performed through 3-D model calculations incorporating physical, chemical and transport characteristics of the global atmosphere.

34. ENVISAT AO - ID:158: CINAMON: Characterisation, INterpretation, Application, and Maturation of key Ozone-related ENVISAT-1 level-2 products, using correlative observations associated with the NDSC

The present project aims at the geophysical validation, from pole to pole and on the long term, of key ozone-related level-2 products (O3, NO2, BrO, OClO, and ClO) from GOMOS, MIPAS and SCIAMACHY onboard ENVISAT-1, and at a contribution to the maturation of the related level-1b-to-2 data processors. Application data processing will be used to convert level-2 data into a more suitable format for validation and scientific end-users. The respective performances of the ENVISAT data products, and their sensitivity to various relevant parameters, will be investigated from the Arctic to the Antarctic, over a variety of geophysical conditions. The impact of these performances on specific atmospheric chemistry studies will be emphasised. The pseudo-global investigations will rely on correlative studies of ENVISAT data with high-quality ground-based, in situ and balloon observations associated with the Network for the Detection of Stratospheric Change (NDSC).

35. ENVISAT AO - ID:126: Validation of ENVISAT-1 level-2 products related to lower atmosphere O3 and NOy chemistry by an FTIR

The project will provide a long-term, pseudo-global validation support to the ENVISAT-1 atmospheric measurements, based on mutually consistent high-quality solar and lunar observations from FTIR spectrometers operated at primary and a number of complementary NDSC stations. The validation is limited to a number of target species, most of which are primary NRT or OL level-2 products of the mission, with focus on NOy components: O3, NO2, NO, N2O, HNO3, HNO4, H2CO, CO and CH4. Synergistic use will be made of column and profile data from MIPAS, GOMOS and SCIAMACHY. The ground network will deliver mean vertical column abundances for all target species with NDSC-type quality, and height profile information for some target gases as secondary products to the PI's home institute, where the correlative analyses with the ENVISAT-1 products will be done. Asynoptic mapping tools will support the validation efforts.

39. EARLINET: A European Aerosol Research Lidar Network to Establish an Aerosol Climatology

EARLINET will establish a quantitative comprehensive statistical database of the horizontal, vertical, and temporal distribution of aerosols on a continental scale. The goal is to provide aerosol data with unbiased sampling, for important selected processes, and air-mass history, together with comprehensive analyses of these data. The objectives will be reached by implementing a network of 21 stations distributed over most of Europe, using advanced quantitative laser remote sensing to directly measure the vertical distribution of aerosols, supported by a suite of more conventional observations. Special care will be taken to assure data quality, including intercomparisons at instrument and evaluation levels. A major part of the measurements will be performed according to a fixed schedule to provide an unbiased statistically significant data set. Additional measurements will be performed to specifically address important processes that are localised either in space or time. Back-trajectories derived from operational weather prediction models will be used to characterise the history of the observed air parcels, accounting explicitly for the vertical distribution.

40. SOGE: System for Observation of halogenated Greenhouse gases in Europe

SOGE is an integrated system for observation of halogenated greenhouse gases in Europe. There are two objectives: (1) To develop a new cost-effective long-term European observation system for halocarbons. The results will be in support of the Kyoto and the Montreal protocols,in assessing the compliance of European regions with the protocol requirements. In particular the observation system will be set up to: - detect trends in the concentrations of greenhouse active and ozone-destroying halocarbons; - verify reported emissions and validate emission inventories; - develop observational capacity for all halocarbons included in the Kyoto protocol (PFC, SF6) for which this is presently not yet existing; - develop a strategy for a cost-effective long-term observation system for halocarbons in Europe. (2) To predict and assess impacts of the halocarbons on the climate and on the ozone layer. This implies extensive exploitation of existing data. The impact assessment will be aimed at providing guidance for development of the Kyoto protocol and to the further development of the Montreal protocol mendments, by: - modelling impacts of halocarbons on radiative forcing and their relative importance for climate change; - modelling impacts of emissions of CFCs and HCFCs on the ozone layer.
