The distribution and abundance of fishes across the Alaska Arctic is not well understood. Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.
Numerous studies utilizing remote sensing imagery and other methods have documented that thermokarst lakes are undergoing varied hydrological transitions in response to recent climate changes, from surface area expansion to drainage and evaporative desiccation. Here, we provide a synthesis of hydrological conditions for 376 lakes of mainly thermokarst origin across high-latitude North America. We assemble surface water isotope compositions measured during the past decade at five lake-rich landscapes including Arctic Coastal Plain (Alaska), Yukon Flats (Alaska), Old Crow Flats (Yukon), northwestern Hudson Bay Lowlands (Manitoba), and Nunavik (Quebec). These landscapes represent the broad range of thermokarst environments...
In Arctic ecosystems, freshwater fish migrateseasonally between productive shallow water habitatsthat freeze in winter and deep overwinter refuge in riversand lakes. How these movements relate to seasonal hydrologyis not well understood.We used passive integratedtransponder tags and stream wide antennae to track1035 Arctic grayling in Crea Creek, a seasonally flowingbeaded stream on the Arctic Coastal Plain, Alaska. Migrationof juvenile and adult fish into Crea Creek peakedin June immediately after ice break-up in the stream. Fishthat entered the stream during periods of high flow andcold stream temperature traveled farther upstream thanthose entering during periods of lower flow and warmertemperature. We used generalized...
There is currently have a very poor understanding of how climate change will affect food web structure and mercury accumulation in lakes on the Arctic Coastal Plain of Alaska. In this study, researchers are addressing this knowledge gap by adopting a space-for-time approach. Fish and food web ecology, and mercury accumulation patterns, are being investigated in several lakes that represent a gradient in temperature/ice phenology of up to two ice-free weeks and 10°C. They are also comparing food web structure and rates of mercury biomagnification among the lakes, and relating these to several climate variables. Finally, they are relating past trends in mercury accumulation in lake sediments to indices of lake productivity...

The Database was built to enable data integration across sources, as well as to support program planning and observational network design. The Imiq Data Portal provides a snapshot of available hydroclimate data – a map-based view of where , what , and when data have been obtained. Users can submit a custom data query, specifying variable of interest, geographic bounds, and time step. Imiq will aggregate and export data records from multiple sources in a common format, with full metadata records that provide information about the source data.

The Arctic Landscape Conservation Cooperative (LCC) and the North Slope Science Initiative have both identified the importance of synthesizing and disseminating existing climate and hydrology data as well as improving the design of climate and hydrologic monitoring networks to meet management and research needs. We have partnered with the Arctic LCC to address this issue. During this project we designed a geodatabase called Imiq, inventoried hydrologic, climate, and related datasets, and populated the Imiq database with both data and metadata. Finally, we analyzed some of the spatial characteristics of the existing hydroclimate data and the observational network structure, in an effort to inform the development...

LCC funding for this project helped maintain a network of hydrology monitoring sites in a representative watershed of the Arctic Coastal Plain. The work was conducted within the context of climate change and impending oil and gas activities in the region, the latter of which is the impetus for focusing on the Fish Creek watershed. The project included two monitoring components:1) Beaded Stream & Lake Hydrology Monitoring (dominant habitat type within the watershed): in 6 stream/lake complex watersheds (Redworm, Hannahbear, Blackfish, Crea, Oil, and Bills creeks), continuous water level and temperature (in lakes, streams, and confluences), discrete discharge measurements, and continuous water quality (specific conductivity,...

Water availability, distribution, quality and quantity are critical habitat elements for fish and other water-dependent species. Furthermore, the availability of water is also a pre-requisite for a number of human activities. The density of weather and hydrology observation sites on the North Slope is orders of magnitude less than in other parts of the U.S., making it difficult to document hydrologic trends and develop accurate predictive models where water is a key input. The information that does exist is scattered among many entities, and varies in format. This multi-year data rescue effort project brings together these scarce and scattered hydrology data sets, including high-priority datasets held by the Bureau...

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

Ideal observation sites are located near tributary-mainstem confluences and provide frequent,synchronous measurements of physical, chemical, and biological attributes. This “nested watershed”design supports characterization of environmental conditions adjacent to the sampling stations, whileinstream hydrological measurements will reflect both local conditions and inputs from upstream. TEON observations sites are stratified by ecoregions, so we can aggregate data sets across the network to characterize conditions at the ecoregion scale.

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for asustainable environmental observing network for northern Alaska. TEON is organized aroundrepresentative focal watersheds (Figure 1). TEON will collect, distribute, and synthesize long-termobservational data needed to detect and forecast effects of a changing climate, hydrology, andpermafrost regime on wildlife, habitat, and infrastructure in northern Alaska.
