Journal ArticleDOI
Sediment and nutrient delivery from thermokarst features in the foothills of the North Slope, Alaska: Potential impacts on headwater stream ecosystems
William B. Bowden,Michael N. Gooseff,Michael N. Gooseff,A. Balser,A. Green,A. Green,Bruce J. Peterson,John H. Bradford +7 more
TL;DR: In this article, an extensive survey of a 600 km2 area in and around the Toolik Lake Natural Research Area (TLNRA) revealed at least 34 thermokarst features, two thirds of which were new since ∼1980 when a high resolution aerial survey of the area was done.
Journal ArticleDOI
Complex Dielectric Permittivity Measurements from Ground-Penetrating Radar Data to Estimate Snow Liquid Water Content in the Pendular Regime
TL;DR: In this paper, the authors measured the frequency-dependent ground-penetrating radar (GPR) signal attenuation and velocity to estimate the complex dielectric permittivity.
Journal ArticleDOI
Transient storage as a function of geomorphology, discharge, and permafrost active layer conditions in Arctic tundra streams
Jay P. Zarnetske,Jay P. Zarnetske,Michael N. Gooseff,Troy R. Brosten,John H. Bradford,James P. McNamara,W. Breck Bowden +6 more
TL;DR: In this paper, the effects of discharge, channel morphology, and potential size of the hyporheic zone on transient storage were investigated using stream tracer experiments in five morphologically diverse tundra streams in Arctic Alaska during the thaw season of 2004.
Journal ArticleDOI
Frequency-dependent attenuation analysis of ground-penetrating radar data
TL;DR: In this paper, the authors derived the band-limited Q* function from a first-order Taylor expansion of the attenuation coefficient, which provides a basis for computing Q* from any arbitrary dielectric permittivity model.
Journal ArticleDOI
Snow stratigraphy over a uniform depositional surface: spatial variability and measurement tools
Joel T. Harper,John H. Bradford +1 more
TL;DR: In this article, the authors compared instrumentation and methods for measuring snow properties in an investigation of millimeter-to meter-scale stratigraphy in a snowpack not influenced by topography, vegetation, or a warm and variable ground surface.
