Water Quality and Macroinvertebrate Data Northern Alaska, 2007
Open-water areas that persist along rivers and lakes during arctic winters can be considered “islands” of open-water embedded within a frozen land. These open-water islands are associated with areas of groundwater inflow, and as a result exhibit relatively stable thermal regimes throughout the year. Their persistence is vital to the fitness and survival of many arctic organisms; thus, these habitats are an invaluable part of GAAR ecosystems. As the arctic climate continues to warm, altering regional as well as local hydrologic regimes, the persistence and ecological functioning of these open-water habitats may be altered dramatically. Researchers have documented the disappearance of many small, high-latitude lakes; however, our knowledge of the quantity and extent of open-water habitats remains scarce. Our objective was to collect baseline water-quality data and document the quantity and extent of these open-water islands and their association with stands of cotton wood and poplar during the winter. This dataset consists of water quality and macroinvertebrate data collected from sites in northern Alaska on May 1, 2007.
