    Breeding and wintering range of common eiders Somateria mollissima in the circumpolar region (not all southern breeding areas included).The common eider Somateria mollissima has a circumpolar distribution breeding mainly on small islands in Arctic and boreal marine areas in Alaska (Bering Sea region), Canada, Greenland, Iceland, N Europe and the Barents Sea region. In mainland Russia, there is a gap in distribution from the Yugorski Peninsula (Kara Sea) to Chaunskaya Bay in E Siberia Important wintering areas include the Gulf of Alaska/Bering Sea/Aleutian region, SE Canada, SW Greenland, Iceland and NW Europe. Six or seven subspecies are recognized, of which four occur in North America. - <a href="http://arcticbiodiversity.is/the-report/chapters/birds" target="_blank">Arctic Biodiversity Assessment.

    Based on published scientific literature, the diversity of plants in the Arctic is reviewed. The plants are divided into three main groups according to essential differences in anatomy, morphology and reproduction. These are vascular plants, bryophytes (mosses and liverworts) and algae (micro- and macroalgae). As a whole, these three plant groups have the ability to perform photosynthesis. As primary producers they play a key role in the environment, since photosynthesis provides resources for all other organisms. Vascular plants and bryophytes (together with the lichenized fungi, the lichens) are the main structural components of terrestrial vegetation and ecosystems, while algae are more abundant in fresh water and marine ecosystems.

    The MODIS Sea Surface Temperature (SST) product provided is a 4km spatialresolution monthly composite made from nighttime measurements from the Aqua Satellite.The nighttime measurements are used to collect a consistent temperature measurement that isunaffected by the warming of the top layer of water by the sun.

    The MODIS Land Water Mask is created from MODIS 250 m imagery incombination with Shuttle Radar Topography Mission (SRTM) Water Body Data (SWBD) tocreate a global map of surface water at 250 m spatial resolution. Currently, only one mapexists, created in 2009 by Carroll et al. (2009). Because only one MODIS-based map exists,an analysis of surface water change is not possible at this time.

    The Circumpolar Biodiversity Monitoring Program, a cornerstone programme of the Conservation of Arctic Flora and Fauna (CAFF), Arctic Council working Group is an international network of scientists, government agencies, Indigenous organizations and conservation groups working together to harmonize and integrate efforts to monitor the Arctic's living resources.CBMP experts are developing four coordinated and integrated Arctic Biodiversity Monitoring Plans to help guide circumpolar monitoring efforts. Results will be channeled into effective conservation, mitigation and adaptation policies supporting the Arctic. These plans represent the Arctic's major ecosystems(Marine, Freshwater, Coastal, Terrestrial). It is important that monitoring programs develop the most effective reporting strategies if they are to inform decision making. To facilitate effective and consistent reporting, the CBMP has chosen a suite of indices and indicators that provide a comprehensive picture of the state of Arctic biodiversity – from species to habitats to ecosystem processes to ecological services. These indices and indicators are developed in a hierarchical manner, allowing users to drill down into the data from the higher-order indices to more detailed indicators. These are being developed through an expert consultation process. The Arctic Species Trend Index (ASTI) is part of this suite of indicators and indices developed by CAFFs CBMP. It tracks trends in over 300 Arctic vertebrate species and comprises the Arctic component of the Living Planet Index. It is important to identify how wildlife and ecosystems are changing in order to develop effective conservation and adaptation strategies in the Arctic, an environment undergoing dramatic changes. The ASTI describes overall trends across species, taxonomy, ecosystems, regions and other categories.

    The MODIS marine chlorophyll a product provided, similar to SST, is a 4 km global monthly composite based on smaller resolution daily imagery compiled by NASA. The imagery is reliant on clear ocean (free of clouds and ice) so only months from March to October have been provided, as the chlorophyll levels in the Arctic diminish during the winter months, when sea ice is prevalent. The marine chlorophyll a is measured in mg/m3

    Figure 4.1. Avian biodiversity in different regions of the Arctic. Charts on the inner circle show species numbers of different bird groups in the high Arctic, on the outer circle in the low Arctic. The size of the charts is scaled to the number of species in each region, which ranges from 32 (Svalbard) to 117 (low Arctic Alaska). CAFF 2013. Arctic Biodiversity Assessment.

    The MODIS Land Cover Type product is created yearly using three landclassification schemes; the International Geosphere Biosphere Programme (IGBP)classification scheme, the Univertiy of Maryland (UMD) classification scheme, and aMODIS-derived Leaf Area Index /Fraction of Photosynthetically Active Radiation(LAI/fPAR) classification scheme (Table 3). The International Geosphere Biosphere Programme (IGBP) identifies seventeenland cover classes, including eleven natural vegetation classes, three non-vegetated landclasses, and three developed land classes. The product provided is derived using the samealgorithm as the 500 m Land Cover Type (MOD12Q1), but is on a 0.05° Climate Model Grid(CMG), that has been clipped to the pan-Arctic extent. The UMD classification scheme issimilar to the IGBP classification scheme, but it excludes the Permanent wetlands,Cropland/Natural vegetation mosaic, and the Snow and ice classes. The LAI/fPARclassification scheme is the smallest of the three, and focuses on forest structure; it only haseleven classes. All three land cover classification schemes are provided, but the IGBPclassification scheme is the most amenable to the Pan-Arctic region.
