Summary of Glaciological Studies in Mizuho Plateau (Special Issue of the Proceedings of the First Symposium on Antarctic Meteorology and Glaciology)

open access: yesAntarctic Record, 1979
A summary report of the traverse glaciology proiect accomplished by the Japanese Antarctic Research Expedition in 1969-1975 was published in 1978 under the title of "Glaciological Studies in Mizuho Plateau, East Antarctica, 1969- 1975" as a special issue

Coupling the U.K. Earth System Model to Dynamic Models of the Greenland and Antarctic Ice Sheets

open access: yesJournal of Advances in Modeling Earth Systems, 2021
The physical interactions between ice sheets and the atmosphere and ocean around them are major factors in determining the state of the climate system, yet many current Earth System models omit them entirely or treat them very simply.

Geographical distribution and volume of Antarctic icebergs derived from ship observation data

open access: yesAnnals of Glaciology, 2017
Information on the occurrence, spatial distribution and morphometric characteristics of Antarctic icebergs is needed in a large number of applications including navigation, heat and freshwater balance calculations, biochemistry of the ocean and ...

Basal freeze-on generates complex ice-sheet stratigraphy

open access: yesNature Communications, 2018
Subsurface ice-sheet radar images reveal large plume-shaped bodies rising from the base, with their origin not yet understood. Here, the authors show that freeze-on of water at the ice-sheet base combined with ice-flux explains the vertical extent, shape

Changes in area, flow speed and structure of southwest Antarctic Peninsula ice shelves in the 21st century

open access: yesJournal of Glaciology, 2022
Since the mid-20th century, ice shelves around the Antarctic Peninsula have declined in extent and thickness, and some have shown signs of structural instability.

Seawater softening of suture zones inhibits fracture propagation in Antarctic ice shelves

open access: yesNature Communications, 2019
Suture zones are abundant on Antarctic ice shelves and widely observed to impede fracture propagation. Here we show that fracture detainment is principally controlled by the zones’ enhanced seawater contents, reducing fracture-driving stresses by orders ...

Physical and biological properties of early winter Antarctic sea ice in the Ross Sea

open access: yesAnnals of Glaciology, 2020
This work presents the results of physical and biological investigations at 27 biogeochemical stations of early winter sea ice in the Ross Sea during the 2017 PIPERS cruise. Only two similar cruises occurred in the past, in 1995 and 1998.

Deep ice core drilling to a depth of 3035.22 m at Dome Fuji, Antarctica in 2001–07

open access: yesAnnals of Glaciology, 2021
The Japanese second deep ice coring project was carried out at Dome Fuji, Antarctica. Following the drilling of the pilot hole in 2001, deep ice core drilling led by the Japanese Antarctic Research Expedition (JARE) was conducted over four austral summer

Geothermal Heat Flux Reveals the Iceland Hotspot Track Underneath Greenland

open access: yesGeophysical Research Letters, 2018
Curie depths beneath Greenland are revealed by spectral analysis of data from the World Digital Magnetic Anomaly Map 2. A thermal model of the lithosphere then provides a corresponding geothermal heat flux map.

Towards Bedmap Himalayas: development of an airborne ice-sounding radar for glacier thickness surveys in High-Mountain Asia

open access: yesAnnals of Glaciology, 2020
The thickness of glaciers in High-Mountain Asia (HMA) is critical in determining when the ice reserve will be lost as these glaciers thin but is remarkably poorly known because very few measurements have been made.
