Progress in Cryoseismology

See call for papers for this particular issue.

The International Glaciological Society (IGS) will publish a special issue of the Annals of Glaciology with the theme ‘Progress in Cryoseismology’. The issue will be part of Annals Volume 60 and will be issue number 79. Papers accepted for publication will be published immediately on the Cambridge University Press (CUP) website, and a final printed version will be available in mid to late 2019.

The special issue will be edited by Chief Editor Fabian Walter (Eidgenössische Technische Hochschule Zürich, ETH) and associate Scientific Editor Doug MacAyeal (University of Chicago).

Main interest: MacAyeal’s seismological expertise is primarily in helping to initiate and deploy experimental seismic arrays to investigate unusual phenomena. The most notable of these phenomena was the origin of ‘iceberg tremor’ which MacAyeal helped to observe by deploying seismometers on freely floating icebergs (pictured right) in 2003–06. MacAyeal has also served as both a Chief Editor of the IGS and as scientific editor of several Annals of Glaciology special issues that have been published since the early 1990s.

Timeline

The issue is intended to complement relevant sessions held at EGU, AGU and elsewhere over the 2018/19 period.

Theme

Various glaciological processes generate elastic waves, and hence seismology has been shedding light on numerous phenomena in the cryosphere. However, with the advent of more portable instrumentation, modern time series analysis and numerical modelling tools, the number of studies on the interdisciplinary connections between seismology and glaciology has rapidly increased, producing more scientific papers in the last decade than in the previous 60 years. Similarly, conference sessions and workshops dedicated to the field of cryoseismology have been held on a yearly basis and attracted attention of earth scientists at all career-levels.

The story of cryoseismology testifies to success of interdisciplinary research: On one hand, glaciological studies provide seismologists with interesting ‘exotic’ seismic sources, which distinguish themselves from common tectonic faulting events. On the other hand, seismology has been offering a set of innovative tools for studying iceberg calving, glacier sliding, subglacial water flow and other aspects of glaciology that are usually hidden from conventional measurements.

Given the rapid developments in cryoseismology, it is becoming more and more difficult to host this field as a sub-discipline of either seismology or glaciology. Instead, a new earth science sub-discipline and scientific community is emerging, whose progress should best be published in dedicated journal series.

This special issue in the Annals of Glaciology aims to cater to this need by

The scope of this special issue focuses on passive seismology, but active firn, ice and near-sub-glacial experiments are welcome.

Topics of interest are:

  1. Seismogenic processes generated at the ice–ocean interface, such as iceberg calving, rifting and water flow beneath ice sheets and ice shelves.
  2. Seismicity of basal sliding
  3. Seismic signals of crevassing, fracturing and failure
  4. Seismic noise in the cryosphere
  5. Numerical models of cryoseismic sources
  6. Using passively acquired seismic signals to study ice structure and changes thereof
  7. Sea ice seismicity
  8. Hydrofracturing in glacial ice
  9. Water tremor in glaciers and ice sheets
  10. Novel approaches for detection, location and monitoring of cryoseismic sources
  11. Automated processing of cryoseismic records
  12. Instrumentation and measurement approaches

Other relevant topic suggestions are welcome. If you have such a suggestion or if you have any questions about the suitability of your paper for this Annals issue, please contact the Chief Editor or one of the associate Scientific Editors.
