Exit Creek Transect Survey, June 2013
This dataset consists of survey data from transects surveyed June 10-12, 2013 along Exit Creek, a stream draining Exit Glacier in Kenai Fjords National Park, Alaska. The survey was conducted using Global Positioning System Real-Time Kinetic (GPS-RTK) transceivers and tied to monuments previously established by the U.S. Forest Service. This survey repeated points from an initial (2011) survey of Transects 2 and 3 by the U.S. Forest Service and established Transects 4-7. The intent of the survey transects is to monitor changes in elevation across the braid plain of Exit Creek.

Exit Creek Water Surface Survey, June 2013
공공데이터포털
This dataset consists of survey data from a longitudinal profile of water surface surveyed June 23-24, 2013 at Exit Creek, a stream draining Exit Glacier in Kenai Fjords National Park, Alaska. The survey was conducted using a total station at multiple instrument locations linked using visual estimates of instrument locations from an orthophoto. The intent of the survey was to provide detailed water surface elevations to compare to a 2012 digital elevation model.

Exit Creek Bank Height Survey, June 2013
공공데이터포털
This dataset consists of survey data from bank profiles surveyed June 12 and June 24-26, 2013 at the edge of the active braid plain of Exit Creek, a stream draining Exit Glacier in Kenai Fjords National Park, Alaska. The survey was conducted using Global Positioning System Real-Time Kinetic (GPS-RTK) transceivers and tied to monuments previously established by the U.S. Forest Service. Short transects (profiles) at 24 locations on the left edge of the braid plain and 12 locations on the right edge of the braid plain were surveyed for the purpose of characterizing the magnitude of bank height and whether the bank sloped up or down from the active braid plain. The intent of the survey was to provide detailed ground conditions at braid plain margins to supplement remotely sensed elevation data.

Exit and Paradise Creek Drainage Area Boundaries, Alaska, 2012
공공데이터포털
This dataset contains drainage area boundaries for Exit Creek and Paradise Creek in Kenai Fjords National Park, Alaska. A drainage area boundary identifies the land area generating surface water that flows to the network of streams above a particular point. In addition to defining the drainage divide, the drainage area boundary provides a bounding area for determining physical and climatic basin characteristics relevant to hydrology. The drainage area boundaries for Exit and Paradise Creeks were developed to compute stream drainage area, percent cover of glaciers or other land cover types, mean basin precipitation and temperature, and other basin characteristics. The drainage area boundaries for Exit and Paradise Creeks include refined glacier divides that may be used to generate glacier boundaries.

Exit and Paradise Creek Fluvial Features, 2012
공공데이터포털
This dataset presents delineations of the braid plains of Exit and Paradise Creeks in Kenai Fjords National Park, Alaska for 2012 conditions. A braid plain can be defined generally as the area over which a braided river shifts, and can include active braid plain (the suite of wetted channels and largely unvegetated intervening bars) and inactive braid plain (vegetated formerly occupied channels and bars still accessible by braiding without substantial bank erosion). An additional category of transitional braid plain here describes areas where vegetation is disturbed by recent sediment transport but not fully removed. Because processes are changing as Exit Glacier retreats, selected former fluvial surfaces are no longer expected to be accessible by typical braiding and may be removed from the braid plain. For 2012 conditions, inactive braid plain mapping was only conducted on Exit Creek downstream of the prominent moraines dating to the 1800s.

Exit and Paradise Creek Fluvial Features, 1950
공공데이터포털
This dataset presents a delineation of the maximum extent of fluvial occupation detectable from vegetation patterns at Exit and Paradise Creeks in Kenai Fjords National Park, Alaska for 1950 conditions. This comprehensive 1950 surface includes the active braid plain, taken as the suite of wetted channels and largely unvegetated intervening bars (Curran and McTeague, 2011), the inactive braid plain, considered here as vegetated formerly occupied channels and bars still accessible by braiding without substantial bank erosion, and surfaces occupied by former glacier drainage but potentially no longer accessible by braiding. For simplicity, this surface also includes isolated non-fluvial features such as bedrock or moraines stranded within the fluvial features.Limited photo resolution and lack of elevation data precluded differentiating the active and inactive surfaces.
