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

Vegetation indices quantify the concentrations of green leaf vegetation (chlorophyll)around the globe, in an attempt to monitor and correlate vegetation health and stress. The MODIS vegetation products include the Normalized Difference Vegetation Index (NDVI)and an Enhanced Vegetation Index (EVI). Included in the MOD13C1 product is both NDVIand EVI, so both have been provided for the CAFF Dedicated Pan-Arctic Satellite RemoteSensing Products and Distribution System. These indices come in a variety of resolutions,but MTRI has provided a monthly global composite on a 0.05° Climate Model GRID(CMG).

The Land Cover Dynamics MODIS product is a yearly product that represents thetiming of vegetation phenology globally. Sub-datasets include vegetation growth, maturity,senescence, and dormancy. This product also includes the NBAR-(Nadir Bidirectionalreflectance distribution function (BRDF) adjusted Reflectance) based EVI, in part becausethe EVI is used to create the Land Cover Dynamics. The Land Cover Dynamics product uses both Terra and Aqua MODIS data. Version005 (provided) has a 500 m spatial resolution, which is an improvement from the 1,000 mversion 004 product. This product is only available in MODIS tiles, so the tiles needed tocover the CAFF pan-Arctic region has been downloaded but not clipped to the pan-Arcticextent at this time.

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.

Colored Dissolved Organic Matter (CDOM) is a measurement of the absorption of light in the UV and visible spectrum by the colored components of dissolved organic carbon. It is essentially the yellow substance in water as a result of decaying detritus. It is important to measure because it limits the amount of sunlight penetration, and thus restricts the growth of plankton populations. It is measured in a unit-less CDOM index. Data generated as part of CAFFs Circumpolar Biodiversity Monitoring Program (CAFF) and its Land Cover Change Initiative (LCC) Trends visible in the MODIS dataset show an overall decrease in the mean CDOM from 2003 to 2012, with a percent change of -31.7%. This trend can be seen in Figure 40. This decrease corresponds to the increase in total yearly primary productivity (Figure 30), as a decrease in the CDOM allows for sunlight to penetrate deeper into the water, boosting chlorophyll concentrations and thus primary productivity.

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 number of species depends partly on what has been studied. Proportions vary somewhat around the Arctic, but diatoms and dinoflagellates are the most diverse groups everywhere. The greatest sampling effort has been in the Laptev Sea, Hudson Bay, and the Norwegian sector of the Barents Sea. Species shown are among the most commonly recorded.
