Viability of karezes (ancient water supply systems in Afghanistan) in a changing world
(SpringerOpen, 2015-09-09)The Afghanistan population living far from rivers relies upon groundwater delivered from karezes (sub-horizontal tunnels). Karezes exploit unconfined groundwater in alluvial fans recharged largely by snowmelt from the Hindu ... -
Sheet, stream and shelf flow as progressice ice-bed uncoupling: Byrd Glacier, Antarctica and Jakobshavn Isbrae, Greenland
(European Geosciences Union, 2016-01-21)The first-order control of ice thickness and height above sea level is linked to the decreasing strength of ice-bed coupling along flowlines from an interior ice divide to the calving front of an ice shelf. Uncoupling ... -
Investigation of Urban Air Temperature and Humidity Patterns during Extreme Heat Conditions Using Satellite-Derived Data
(American Meteorological Society, 2015-11)Extreme heat is a leading cause of weather-related human mortality. The urban heat island (UHI) can magnify heat exposure in metropolitan areas. This study investigates the ability of a new MODIS-retrieved near-surface air ... -
Two methods for estimating limits to large-scale wind power generation
(National Academy of Sciences, 2015-09-08)Wind turbines remove kinetic energy from the atmospheric flow, which reduces wind speeds and limits generation rates of large wind farms. These interactions can be approximated using a vertical kinetic energy (VKE) flux ... -
Designing a Suite of Models to Explore Critical Zone Function
(Elsevier, 2014-08)Critical Zone; weathering; hydrology; ecology; watersheds -
Boron isotope fractionation in soils at Shale Hills CZO
(Elsevier, 2014-08)Isotope fractionation of many elements can fingerprint the biogeochemical, weathering and erosion processes that govern the evolution of the Critical Zone (CZ). This study investigates boron isotope fractionation in two ... -
Research Aircraft Determination of D-Value Cross Sections
(American Meteorological Society, 2016-02)Use of an airborne platformto determine the dynamics of atmosphericmotion has been ongoing for over three decades. Much of the effort has been centered on the determination of the horizontal pressure gradient force along ... -
Health worker migration from South Africa: causes, consequences and policy responses

Health worker migration from South Africa: causes, consequences and policy responses
(BioMed Central, 2015)Background This paper arises from a four-country study that sought to better understand the drivers of skilled health worker migration, its consequences, and the strategies countries have employed to mitigate negative ... -
A PDF-Based Microphysics Parameterization for Shallow Cumulus Clouds
(American Meteorological Society, 2014-03)Unbiased calculations of microphysical process rates such as autoconversion and accretion in mesoscale numerical weather prediction models require that subgrid-scale (SGS) variability over the model grid volume be taken ... -
Basal conditions of two Transantarctic Mountains outlet glaciers from observation-constrained diagnostic modelling
(International Glaciological Society, 2014-11)We present a diagnostic glacier flowline model parameterized and constrained by new velocity data from ice-surface GPS installations and speckle tracking of TerraSAR-X satellite images, newly acquired airborne-radar data, ... -
Flow dynamics of Byrd Glacier, East Antarctica
(International Glaciological Society, 2014-12)Force-balance calculations on Byrd Glacier, East Antarctica, reveal large spatial variations in the along-flow component of driving stress with corresponding sticky spots that are stationary over time. On the large scale, ... -
Seasonal variations in brightness temperature for central Antarctica
(International Glaciological Society, 1993-01-01) -
New and improved determinations of velocity of ice streams B and C, West Antarctica
(International Glaciological Society, 1993-01-01)Measurements of velocity have been made on and next to Ice Streams B and C, West Antarctica. The results are more precise than previous work and constitute a 93% increase in the number of values. These velocities are used ... -
Effect of extension rate on terminus position, Columbia Glacier, Alaska, U.S.A
(International Glaciological Society, 1997-01-01) -
Reply to Lliboutry's letter 'Why calculated basal drags of ice streams can be fallacious'
(International Glaciological Society, 1995-01-01)No abstract is available for this item. -
Tidewater calving
(International Glaciological Society, 1996-01-01)Data from Columbia Glacier are used to identify processes that control calving from a temperate tidewater glacier and to re-evaluate models that have been proposed to describe iceberg calving. Since 1981, Columbia Glacier ... -
Model experiments on the evolution and stability of ice streams
(International Glaciological Society, 1996-01-01) -
Weaving Indigenous science, protocols and sustainability science
(Springer, 2015-04-02)The proceedings of the National Science Foundation supported WIS2DOM workshop state that sustainability scientists must respect the “protocols” of practitioners of Indigenous sciences if the practitioners of the two knowledge ... -
Force budget: III, Application to three-dimensional flow of Byrd Glacier, Antarctica
(International Glaciological Society, 1989-09-05)Stresses at the surface and at depth are calculated for a stretch of Byrd Glacier, Antarctica. The calculations are based on photogrammetrically determined velocities and elevations, and on radio-echo-determined ice ...
