Validation for Ice Flow Velocity Variations of Shirase Glacier Derived From PALSAR-2 Offset Tracking

Autor: Kazuki Nakamura, Shigeru Aoki, Tsutomu Yamanokuchi, Takeshi Tamura, Koichiro Doi

Publikováno v: IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol 15, Pp 3269-3281 (2022)

We have shown that the flow velocity of Shirase Glacier can be estimated by applying the offset tracking method to the amplitude images derived from the phased array type L-band synthetic aperture radar type-2 (PALSAR-2) onboard the Advanced Land Obs

Interactive movements of outlet glacier tongue and landfast sea ice in Lützow-Holm Bay, East Antarctica, detected by ALOS-2/PALSAR-2 imagery

Autor: Kazuki Nakamura, Shigeru Aoki, Tsutomu Yamanokuchi, Takeshi Tamura

Publikováno v: Science of Remote Sensing, Vol 6, Iss , Pp 100064- (2022)

The Shirase Glacier, one of the fastest-flowing outlet glaciers in East Antarctica, flows into a bay that is usually covered by landfast sea ice. Although the presence of landfast ice is considered to stabilize glacier tongue, quantitative assessment

Satellite Derived Bathymetry Using Machine Learning and Multi-Temporal Satellite Images

Autor: Tatsuyuki Sagawa, Yuta Yamashita, Toshio Okumura, Tsutomu Yamanokuchi

Publikováno v: Remote Sensing, Vol 11, Iss 10, p 1155 (2019)

Shallow water bathymetry is important for nautical navigation to avoid stranding, as well as for the scientific simulation of high tide and high waves in coastal areas. Although many studies have been conducted on satellite derived bathymetry (SDB),

Regional Geomorphological Conditions Related to Recent Changes of Glacial Lakes in the Issyk-Kul Basin, Northern Tien Shan

Autor: Mirlan Daiyrov, Chiyuki Narama, Tsutomu Yamanokuchi, Takeo Tadono, Andreas Kääb, Jinro Ukita

Publikováno v: Geosciences, Vol 8, Iss 3, p 99 (2018)

To assess the current state of glacial lakes, we examine the seasonal lake-area changes of 339 glacial lakes in the Teskey and Kungoy Ranges of the Issyk-Kul Basin, Kyrgyzstan, during 2013–2016 based on optical satellite images (Landsat7/ETM+ and 8

Evaluating the Scale and Potential of GLOF in the Bhutan Himalayas Using a Satellite-Based Integral Glacier–Glacial Lake Inventory

Autor: Hiroto Nagai, Jinro Ukita, Chiyuki Narama, Koji Fujita, Akiko Sakai, Takeo Tadono, Tsutomu Yamanokuchi, Nobuhiro Tomiyama

Publikováno v: Geosciences, Vol 7, Iss 3, p 77 (2017)

A comprehensive glacier–glacial lake inventory was developed for the Bhutan Himalayas based on satellite observations between 1987–1990 and 2006–2011. In total, 733 lakes (covering 82.6 km2) were delineated between 4000 and 6000 m a.s.l. and th

InSAR Detection and Field Evidence for Thermokarst after a Tundra Wildfire, Using ALOS-PALSAR

Autor: Go Iwahana, Masao Uchida, Lin Liu, Wenyu Gong, Franz J. Meyer, Richard Guritz, Tsutomu Yamanokuchi, Larry Hinzman

Publikováno v: Remote Sensing, Vol 8, Iss 3, p 218 (2016)

Thermokarst is the process of ground subsidence caused by either the thawing of ice-rich permafrost or the melting of massive ground ice. The consequences of permafrost degradation associated with thermokarst for surface ecology, landscape evolution,
