This strategic plan is a guiding framework that lays out the objectives and goals for Alaska Hydrology Technical Working Group and AK Hydro to accomplish high-resolution statewide hydrography updates that meet national mapping standards and local partners’ needs.The strategic plan identifies five key objec-tives: 1) Map Alaska’s Water 2) Support Alaska’s Hydrography Needs 3) provide Hydrography Services 4) establish a Sus-tainable Hydrography future and 5) allow for Data Integration. These strategic objectives will give AK Hydro and AHTWG success in meeting the mission to efficiently serve the hydrography needs of Alaska. The objectives as-sist in mapping the surface water of Alaska, meeting NHD standards, securing...

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...

Map of the Hulahula River Area and location of observation sites. This focal watershed provides the greatest opportunity to characterize conditions within and fluxes from the Brooks Range Ecoregion. Though the Foothills region isextensive, the watersheds narrow as they cross the Coastal Plain in the easternpart of the North Slope. Inset shows the location of the seven TEON focal watersheds.

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.

Map of the Upper Koyukuk River Area and location of proposed observation sites (numbered circles). This large area drains the southern Brooks Range ecoregion and extends downstream into the Kobuk Ridges and Valleys outside of the Arctic LCC boundary. Compared to other sites in TEON, these rivers are larger basins and reflect higher relief landscapes. Inset shows the location of the seven TEON focal watersheds. Image by Arctic LCC staff.

The Terrestrial Environmental Observation Network (TEON) is an effort to establish a sustainable environmental observing network of northern Alaska. TEON will focus work in watersheds that collectively represent the diversity of landscape settings at the ecoregional scale, take advantage of existing science infrastructure and logistics capacity, and provide opportunities to build on existing long-term data sets. Candidate watersheds for TEON include Agashashok River, Barrow/Meade River, Fish/Judy Creek, Hulahula/Jago River, Kokolik River, Kuparuk River, and Upper Koyukuk River.

Arey Lagoon and Island, situated on the Beaufort Sea coast just west of Barter Island and within the Arctic National Wildlife Refuge (ANWR), was selected as a focus site for an in-depth study of coastal processes on a regional to local scale. Arey Lagoon and adjacent areas encompass a barrier island chain, a glacially fed river and delta (Hulahula and Ogpilak Rivers) from the Brooks Range watershed, low-lying tundra with coastal wet sedge, and thermokarst lakes that all may be vulnerable to the effects of changing storm patterns in response to climate change.Analysis of historical maps and imagery showed that Arey Lagoon mainland coast, partially protected by Arey Island from the direct attack of ocean waves, was...

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

TEON uses a “nested” approach to data collection. The smallest unit within TEON is a Station. Stationsinclude discrete sampling locations or units (e.g., plot or transect) where repeated measures of a givenvariable are collected to create a time-series. Data collected at a station may be relevant to localconditions (e.g., soil temperature at a given site) or applicable to a larger area (e.g., streamgage locatedat the lower end of a watershed). A Site is a collection of stations that are typically located within closeproximity to each other. Sites are grouped into Watersheds. Watersheds will encompass many ecotypes and span multiple ecoregions. Watersheds in aggregate form the TEON network.

Map of the Agashashok River Area and location of proposed observation sites (numbered circles). This focal watershed is in the southwest corner of the Arctic LCC and largely drains the Brooks Range ecoregion with a small portion of the lower basin in the Kobuk Ridges and Valleys ecoregion. The braided character of the lower river prevents us from suggesting a long term gaging station in that location. Inset shows the location of the seven TEON focal watersheds.

Alaska is an expansive state with abundant water resources. The complex landscape is defined by water and ice, but Alaska lacks quality mapping of its surface water features. The Alaska Hydrography Technical Working Group and Alaska Hydrography Database have worked to establish the Alaska Hydrography Strategic Plan to promote and guide a core mission to efficiently serve the current and future hydrography needs of Alaska for the next five years. This work will update the state’s hydrography in the National Hydrography Database from its current condition to meet national 1:24,000-scale standards. This work has focused on coordination of hydrography needs with partners and land managers, planning for the future hydrography...
