Automated classification of debris-covered glaciers combining optical, SAR and topographic data in an object-based environment
Robson, Benjamin Aubrey; Nuth, Christopher; Dahl, Svein Olaf; Hölbling, Daniel; Strozzi, Tazio; Nielsen, Pål Ringkjøb (Peer reviewed; Journal article, 2015-12)Satellite imagery is increasingly used to monitor glacier area changes and create glacier inventories. Robust and efficient pixel-based band ratios have proven to be accurate for automatically delineating clean glacier ... -
Automated detection of rock glaciers using deep learning and object-based image analysis
Robson, Benjamin Aubrey; Bolch, Tobias; MacDonell, Shelley; Hölbling, Daniel; Rastner, Philipp; Schaffer, Nicole (Journal article; Peer reviewed, 2020)Rock glaciers are an important component of the cryosphere and are one of the most visible manifestations of permafrost. While the significance of rock glacier contribution to streamflow remains uncertain, the contribution ... -
Decadal Scale Changes in Glacier Area in the Hohe Tauern National Park (Austria) Determined by Object-Based Image Analysis
Robson, Benjamin Aubrey; Hölbling, Daniel; Nuth, Christopher; Strozzi, Tazio; Dahl, Svein Olaf (Peer reviewed; Journal article, 2016-01-15)In this paper, we semi-automatically classify clean and debris-covered ice for 145 glaciers within Hohe Tauern National Park in the Austrian Alps for the years 1985, 2003, and 2013. We also map the end-summer transient ... -
Long‐term impact of the proglacial lake Jökulsárlón on the flow velocity and stability of Breiðamerkurjökull glacier, Iceland
Baurley, Nathaniel; Robson, Benjamin Aubrey; Hart, Jane K. (Journal article; Peer reviewed, 2020)Proglacial lakes are becoming ubiquitous at the termini of many glaciers worldwide due to continued climate warming and glacier retreat, and such lakes have important consequences for the dynamics and future stability of ... -
Quantification and Change Assessment Benjamin Aubrey Robson 2016 Dissertation date: 31st October 2016 of Debris-Covered Glaciers using Remote Sensing
Robson, Benjamin Aubrey (Doctoral thesis, 2016-10-31)This thesis investigates how remote sensing data can be used to assess the changing state of debris-covered ice. The principal study areas are the Manaslu Region in Nepal (papers I and III) and the Hohe Tauern National ... -
Spatial Variability in Patterns of Glacier Change across the Manaslu Range, Central Himalaya
Robson, Benjamin Aubrey; Nuth, Christopher; Nielsen, Pål Ringkjøb; Girod, Luc Maurice Ramuntcho; Hendrick, Marijn; Dahl, Svein Olaf (Peer reviewed; Journal article, 2018-02-13)This study assesses changes in glacier area, velocity, and geodetic mass balance for the glaciers in the Manaslu region of Nepal, a previously undocumented region of the Himalayas. We studied changes between 1970 (for ... -
Surface melt driven summer diurnal and winter multi-day stick-slip motion and till sedimentology
Hart, Jane K; Martinez, Kirk; Basford, Philip J; Clayton, Alexander I; Robson, Benjamin Aubrey; Young, David S (Peer reviewed; Journal article, 2019-04-08)Fluctuations in glacier motion are very common and are thought to be controlled by subglacial hydrology and till deformation. There are few instrumented studies that have monitored seasonal changes. We use the innovative ...
