This dataset contains small cutthroat trout lakes within Southeast Alaska. These are smaller lakes that do not produce cutthroat trout large enough to reach the 11-inch regional minimum size limit. Each of these lakes has a 9-inch minimum size limit, and bait is prohibited. Regionwide limits of 2 per day and 2 in possession apply. Currently there are seven lakes in Southeast Alaska with the small cutthroat lake designation.

Conservation Biology Institute selected closed USFS roads from the "Roads with Core Attributes" dataset based on the following criteria:Roaded areas for closed roads were determined based on the NFS definition:"ROUTE_STATUS" = 'EX - EXISTING' AND "JURISDICTION" = 'FS - FOREST SERVICE' AND "SYSTEM" = 'NFSR - NATIONAL FOREST SYSTEM ROAD' AND ("OPER_MAINT_LEVEL" = '1 - BASIC CUSTODIAL CARE (CLOSED)')Original metadata: A route feature stores the spatial locations (geography) of the road. These feature classes have an (M) value or measure on their vertices. A route system depicts all roads within or in close proximity to an administrative unit. A road is a motor vehicle travel way over 50 inches wide, unless classified...
Digital elevation model of Sitka Harbor and the city of Sitka, Alaska: Procedures, data sources, and quality assessment
The 0.53-second Sitka Alaska Digital Elevation Model provides bathymetric and topographic data in ASCII raster format of 0.53-second resolution in geographic coordinates.
As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this dataset's metadata for an older version of the source data.This map service contains two barrier layers, one from the USFS and one from the AWC. The USFS barriers layer contains points representing bedrock waterfalls in Southeast Alaska that are potential barriers to fish passage on the Tongass National Forest. Waterfalls less than 1 meter are not mapped nor are those caused only by wood or debris jams. Channel types considered to be de facto barriers to fish passage HC5, HC6, & MC3 (Channel Type Users Guide, USFS 1992) were not included in the layer. The AWC layer is undocumented at this time.
This dataset contains polygons describing photo interpreted map classifications of the Tongass National Forest developed in 1978. The dataset's primary objective was to delineate major land types and their attributes. The land types were mapped at a polygon level - areas generally homogenous in character. Mapping was done to a 10 acre minimum except for non-commercial and non-forest types which were mapped to a 5 acre minimum. The classification identifies water as well as land. It segregates land into non-forest and forest. Polygons in forested areas were assigned a single, representative set of attributes; species composition, age, and volume class. Tim86 was updated in the 1980's (mostly in 1986) to reflect timber...
This geospatially explicit vector-based polygon dataset identifies 85 terrestrial ecological subsection delineations present in Southeast Alaska and the Tongass National Forest. Within each subsection one can expect to find a relatively consistent occurence and distribution of vegetation types. Due to the hydrologically-influenced geomorphology of Southeast Alaska specific key indicators of physiography, lithology, and surface geology were employed to systematically distinguish terrestrial ecosystems.
The State of Alaska has more coastline than the rest of the United Statescombined and extends from the high Arctic to the temperate rainforests and marine waters of Southeast Alaska. Climate change impacts are unique in the Southeast Alaska region and are longer term impacts such as heavy rains causing flooding, ocean acidification, warmer waters, snowfall variations, warm springs followed by frost affecting wild berry production, invasive species, and toxins in the marine environment. These factors impact food security and culturally important resources. This project will provide a summit for Southeast Alaska tribal environmentalcoordinators and other stakeholders tosupport natural and cultural resource conservation...
A depiction of the boundary that encompasses a Ranger District. The original dataset was clipped to display select ranger districts within the Tongass National Forest.
This project, with funding support by the North Pacific Landscape Conservation Cooperative andpartners, will address the need to better understand the impact that climate change will have on oursalmon subsistence resources in southeast Alaska. Working with federal and state agencies, as well ascommunity-based organizations and tribal governments, this project will 1) build a network that supportslocal organizations in their efforts to collect stream temperature data, and 2) coordinate those efforts sothat the data will inform and empower management agencies, researchers, and communities to adapt tochanging conditions for fish in the freshwater stages of their lifecycles.
The State of Alaska Division of Geological & Geophysical Surveys (DGGS) produced an orthorectified aerial optical image mosaic (orthoimage) and digital surface model over an area extending from milepost (MP) 17 to approximately MP 24.5 on the Alaska State Highway 7 (Haines Highway) north of Haines along the Chilkat River in southeast Alaska. The aerial photogrammetric survey targeted large debris fans and their alpine source areas on the west side of the Takshanuk Mountains in support of cryosphere hazards mapping and monitoring efforts. Aerial photographs and Global Navigation Satellite System (GNSS) data were collected on May 26, 2014, and were processed using Structure-from-Motion (SfM) photogrammetric techniques...
This dataset contains polygons describing the propensity for deep snow.
The Transportation map service allows desktop GIS users to map transportation datasets for Southeast Alaska.
This dataset was created in order to facilitate transboundary conservation work and research projects, by integrating land cover maps into a single dataset from Cape Caution, BC, to Yakutat Bay, AK. It includes three levels of land classification, site index, elevation, hydric soils (yes/no), karst (yes/no), primary and secondary species, size class, and volume class. It also includes a number of other important attributes from individual datasets, which were not crosswalked between the different areas. These data, originally published here , were converted to ArcGIS Raster files by the NPLCC (North Pacific Landscape Conservation Cooperative) for publication as map services on ScienceBase.
Between 1979 and 1982, the Alaska Division of Geological & Geophysical Surveys (DGGS) and the Geophysical Institute, University of Alaska Fairbanks, undertook an assessment of the states geothermal resources under a program jointly sponsored by the U.S. Department of Energy and the State of Alaska. During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS.

This file represents site index, or the number of meters trees would be expected to grow in 50 years.
CoverType is a photo-interpreted delineation of the Tongass National Forest by land type and timber cover type. Classification of lands was done sequentially: 1) land and water identified; 2) forested and non-forested areas were identified; 3) forested areas were classified by forest type and forest productivity; and 4) productive forest lands were further characterized by volume class, tree size, species composition. The original classifications were based on photo-interpretation of 1:15840 aerial photographs in 1978. The minimum map unit size is approximately 10 acres, though the average area for forested polygons is 60 acres. Additionally, CoverType is updated for new stands created through natural events or...

The dataset was created as part of the Tongass National Forest's submission to the National Hydrography Dataset. As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this metadata for an older version of the source data. This dataset depicts glaciers in Southeast Alaska.
In this report, we evaluate potential tsunami hazards for southeastern Alaska communities of Elfin Cove, Gustavus, and Hoonah and numerically model the extent of inundation from tsunami waves generated by tectonic and landslide sources. We perform numerical modeling of historic tsunami events, such as the tsunami triggered by the 1964 Great Alaska Earthquake, and the tsunami waves generated by the recent 2011 Tohoku and 2012 Haida Gwaii earthquakes. Hypothetical tsunami scenarios include variations of the extended 1964 rupture, megathrust earthquakes in the Prince William Sound and Alaska Peninsula regions, and a Cascadia megathrust earthquake. Local underwater landslide events in Taylor Bay and Port Frederick,...
Official Recognized Boundaries of Fish Habitat Partnerships of the National Fish Habitat Partnership, 2013
This geodatabase contains the official partnership boundaries of the National Fish Habitat Partnership (NFHP). Several boundaries were originally developed by the United States Fish and Wildlife Service and were updated in 2013 to reflect revisions from the recognized Fish Habitat Partnerships (FHPs) of the National Fish Habitat Partnership. For the remaining FHPs, the boundaries were developed in 2013 to reflect the boundary as defined by the respective partnerships. The geodatabase contains two feature datasets. The 'Boundaries' feature dataset includes official partnership boundaries. The 'Subregions_States' feature dataset includes partnership boundaries along with state and/or subregion boundaries.
