Up-glacier propagation of surface lowering of Yala Glacier, Langtang Valley, Nepal Himalaya
Autor: Sojiro Sunako, Koji Fujita, Takeki Izumi, Satoru Yamaguchi, Akiko Sakai, Rijan Bhakta Kayastha
Publikováno v: Journal of Glaciology, Vol 69, Pp 425-432 (2023)
We quantify the surface elevation changes along Yala Glacier in Langtang Valley, Nepal Himalaya, since 1981 using geodetic methods to understand the recent evolution and current state of small debris-free glaciers across the region. We analyse differ

Ice Cliff Dynamics of Debris-Covered Trakarding Glacier in the Rolwaling Region, Nepal Himalaya

Publikováno v: Frontiers in Earth Science, Vol 9 (2021)
Ice cliffs can act as “hot spots” for melt on debris-covered glaciers and promote local glacier mass loss. Repeat high-resolution remote-sensing data are therefore required to monitor the role of ice cliff dynamics in glacier mass loss. Here we a

Mass balance of Trambau Glacier, Rolwaling region, Nepal Himalaya: in-situ observations, long-term reconstruction and mass-balance sensitivity
Autor: SOJIRO SUNAKO, KOJI FUJITA, AKIKO SAKAI, RIJAN B. KAYASTHA
Publikováno v: Journal of Glaciology, Vol 65, Pp 605-616 (2019)
We conducted a mass-balance study of debris-free Trambau Glacier in the Rolwaling region, Nepal Himalaya, which is accessible to 6000 m a.s.l., to better understand mass-balance processes and the effect of precipitation on these processes on high-ele

A novel method to visualize liquid distribution in snow: superimposition of MRI and X-ray CT images
Autor: Satoru Yamaguchi, Satoru Adachi, Sojiro Sunako
Publikováno v: Annals of Glaciology, Pp 1-11
The relationship between the behavior of water in snow and its microstructure is crucial to improve the prediction of wet snow disasters. X-ray computed tomography (X-ray CT) is frequently used to observe snow microscopically. However, distinguishing

Ice cliff mass-loss of debris-covered Trakarding Glacier, Rolwaling region, eastern Nepal Himalaya
Autor: Yota Sato, Pascal Buri, Evan Miles, Marin Kneib, Sojiro Sunako, Akiko Sakai, Francesca Pellicciotti, Koji Fujita
Glaciers in High Mountain Asia have been shrinking in the recent decades. They are a valuable indicator of climate change, and their meltwater plays an important role for regional water resources. Debris-covered glaciers, which are prevalent througho

Viscoelastic Modeling of Nocturnal Thermal Fracturing in a Himalayan Debris‐Covered Glacier
Autor: Koji Fujita, Evgeny A. Podolskiy, Sojiro Sunako, Yota Sato
Publikováno v: Journal of Geophysical Research: Earth Surface. 124:1485-1515
Recent observations suggest that the nocturnal thermal fracturing of ice occurs at relatively warm temperatures (above -15 degrees C) at a high-altitude Himalayan glacier system unless the ice is shielded by a debris mantle. Here we estimate the stre

Debris-covered glacier anomaly? Morphological factors controlling changes in the mass balance, surface area, terminus position, and snow line altitude of Himalayan glaciers
Autor: Akiko Sakai, Franco Salerno, Sojiro Sunako, Sudeep Thakuri, Takayuki Nuimura, Koji Fujita, Gianni Tartari
Publikováno v: Earth and Planetary Science Letters. 471:19-31
What are the main morphological factors that control the heterogeneous responses of debris-covered glaciers to climate change in the southern central Himalaya? A debate is open whether thinning rates on debris-covered glaciers are comparable to those

Coseismic avalanches and rockfalls, as well as their simultaneous air blast and muddy flow, which were induced by the 2015 Gorkha earthquake in Nepal, destroyed the village of Langtang. In order to reveal volume and structure of the deposit covering
