Recent elevation changes of Svalbard glaciers derived from ICESat laser altimetry

G Moholdt, C Nuth, JO Hagen, J Kohler - Remote Sensing of Environment, 2010 - Elsevier
We have tested three methods for estimating 2003–2008 elevation changes of Svalbard
glaciers from multi-temporal ICESat laser altimetry: (a) linear interpolation of crossover points …

A reconciled estimate of glacier contributions to sea level rise: 2003 to 2009

AS Gardner, G Moholdt, JG Cogley, B Wouters… - science, 2013 - science.org
Glaciers distinct from the Greenland and Antarctic Ice Sheets are losing large amounts of
water to the world’s oceans. However, estimates of their contribution to sea level rise disagree. …

The Randolph Glacier Inventory: a globally complete inventory of glaciers

…, G Kaser, C Kienholz, ES Miles, G Moholdt… - Journal of …, 2014 - cambridge.org
The Randolph Glacier Inventory (RGI) is a globally complete collection of digital outlines of
glaciers, excluding the ice sheets, developed to meet the needs of the Fifth Assessment of the …

Increased West Antarctic and unchanged East Antarctic ice discharge over the last 7 years

AS Gardner, G Moholdt, T Scambos, M Fahnstock… - The …, 2018 - tc.copernicus.org
Ice discharge from large ice sheets plays a direct role in determining rates of sea-level rise.
We map present-day Antarctic-wide surface velocities using Landsat 7 and 8 imagery …

Substantial glacier mass loss in the Tien Shan over the past 50 years

D Farinotti, L Longuevergne, G Moholdt… - Nature …, 2015 - nature.com
Populations in Central Asia are heavily dependent on snow and glacier melt for their water
supplies. Changes to the glaciers in the main mountain range in this region, the Tien Shan, …

Sharply increased mass loss from glaciers and ice caps in the Canadian Arctic Archipelago

AS Gardner, G Moholdt, B Wouters, GJ Wolken… - Nature, 2011 - nature.com
Mountain glaciers and ice caps are contributing significantly to present rates of sea level rise
and will continue to do so over the next century and beyond 1 , 2 , 3 , 4 , 5 . The Canadian …

Basal mass budget of Ross and Filchner‐Ronne ice shelves, Antarctica, derived from Lagrangian analysis of ICESat altimetry

G Moholdt, L Padman, HA Fricker - Journal of Geophysical …, 2014 - Wiley Online Library
Traditional methods of deriving temporal variability of Antarctic ice‐shelf elevation from satellite
altimetry use a fixed (“Eulerian”) reference frame, where the measured changes include …

The glaciers climate change initiative: Methods for creating glacier area, elevation change and velocity products

…, A Luckman, JPM Boncori, G Moholdt… - Remote Sensing of …, 2015 - Elsevier
Glaciers and their changes through time are increasingly obtained from a wide range of
satellite sensors. Due to the often remote location of glaciers in inaccessible and high-mountain …

Reanalysing glacier mass balance measurement series

…, C Nuth, SU Nussbaumer, G Moholdt… - The …, 2013 - tc.copernicus.org
Glacier-wide mass balance has been measured for more than sixty years and is widely used
as an indicator of climate change and to assess the glacier contribution to runoff and sea …

Decadal changes from a multi-temporal glacier inventory of Svalbard

…, JO Hagen, A Kääb, G Moholdt… - The …, 2013 - tc.copernicus.org
We present a multi-temporal digital inventory of Svalbard glaciers with the most recent from
the late 2000s containing 33 775 km 2 of glaciers covering 57% of the total land area of the …
