Glacier mass balances (1993–2001), Taylor Valley, McMurdo Dry Valleys, Antarctica

Autor: Andrew G. Fountain, Thomas H. Nylen, Karen Lewis MacClune, Gayle L. Dana

Publikováno v: Journal of Glaciology. 52:451-462

Mass balances were measured on four glaciers in Taylor Valley, Antarctica, from 1993 to 2001. We used a piecewise linear regression, which provided an objective assessment of error, to estimate the mass balance with elevation. Missing measurements we

Inconspicuous Nutrient Laden Surface Runoff from Mature Forest Sierran Watersheds

Autor: P. S. J. Verburg, Roger F. Walker, C. Denton, Watkins W. Miller, Dale W. Johnson, Gayle L. Dana

Publikováno v: Water, Air, and Soil Pollution. 163:3-17

It is generally held that surface runoff in heavily forested ecosystems is minimal and therefore nutrient fluxes via runoff are unimportant. This is based in large measure on the absence of direct observation or remnant physical evidence. It is furth

Surface glaciochemistry of Taylor Valley, southern Victoria Land, Antarctica and its relationship to stream chemistry

Autor: Kathleen A. Welch, W. Berry Lyons, Bruce H. Vaughn, Diane M. McKnight, Gayle L. Dana, Andrew G. Fountain

Publikováno v: Hydrological Processes. 17:115-130

We have analysed a series of surface samples from the alpine glaciers of Taylor Valley, Southern Victoria Land, Antarctica for their geochemical composition. This was done to better establish the role of glaciochemical variation on the chemical compo

Satellite-derived indices of stream discharge in Taylor Valley, Antarctica

Autor: Robert A. Wharton, Gayle L. Dana, Robert E. Davis, Andrew G. Fountain

Publikováno v: Hydrological Processes. 16:1603-1616

Temperature indices from NOAA–AVHRR data were developed to predict diurnal and seasonal streamflow in Taylor Valley, Antarctica. Masks of the primary land-cover types (snow, glacier ice, lake ice, and soils) were created from Landsat TM data using

How important is terminus cliff melt?: a study of the Canada Glacier terminus, Taylor Valley, Antarctica

Autor: Andrew G. Fountain, Gayle L. Dana, Karen J. Lewis

Publikováno v: Global and Planetary Change. 22:105-115

The glacier terminus cliffs on Canada Glacier, Taylor Valley, Antarctica represent 2% of the total ablation zone, but account for 15–20% of the overall meltwater runoff from the glacier during the 1995–1996 and 1996–1997 summers. To ascertain w

Surface energy balance and meltwater production for a Dry Valley glacier, Taylor Valley, Antarctica

Autor: Karen J. Lewis, Andrew G. Fountain, Gayle L. Dana

Publikováno v: Annals of Glaciology. 27:603-609

The surface energy balance was calculated to estimate sublimation and melt on the surface and terminus of Canada Glacier, Taylor Valley, Antarctica, during the 1994-95 and 1995-96 austral summers. Our results indicate that sublimation accounted for r
