Detecting Snow Avalanche Activity Using Infrasound: Hooker Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Snow avalanches pose considerable hazards to people and infrastructure in alpine environments. Traditional avalanche monitoring relies on meteorological data and visual observations, which can be limited in scope and timeliness. Infrasound offers a promising complementary monitoring tool by detecting the low‐frequency sound waves generated by ...

Wind-driven upwelling around grounded tabular icebergs [PDF]

, 2015
Funding was provided by NSF Polar Programs - Grant Number: ARC-1304137.Temperature and salinity data collected around grounded tabular icebergs in Baffin Bay in 2011, 2012 and 2013 indicate wind-induced upwelling at certain locations around the icebergs.

Modelled dynamics of floating and grounded icebergs, with application to the Amundsen Sea [PDF]

The Cryosphere
Icebergs that ground on the submarine Bear Ridge in the Amundsen Sea are known to block the drift of sea ice, playing a crucial role in maintaining shelf sea ocean conditions.

The integrated ice sheet response to stochastic iceberg calving

Journal of Glaciology
Abstract Iceberg calving is a major source of ice loss from the Antarctic and Greenland ice sheets. However, it is still one of the most poorly understood aspects of ice sheet dynamics, in part due to its variability at a wide range of spatial and temporal scales.

Prospects for seasonal forecasting of iceberg distributions in the North Atlantic [PDF]

, 2017
An efficient approach to ocean–iceberg modelling provides a means for assessing prospects for seasonal forecasting of iceberg distributions in the northwest Atlantic, where icebergs present a hazard to mariners each spring.

Greenland Ice Sheet's Distinct Calving Styles Are Identified in Terminus Change Timeseries

Geophysical Research Letters
At least three primary iceberg calving styles have been identified in Greenland: serac collapse, which produces falling icebergs tens of meters in length; slab capsize, which produces rotating icebergs hundreds of meters in length; and tabular rifting ...

Tsunami [PDF]

This lesson plan is part of the DiscoverySchool.com lesson plan library for grades 6-8. It focuses on tsunamis and the destruction they can cause. Students design experiments to view the two types of tsunamis (fjord and ocean) and view the different wave

Quantifying flow and stress in ice mélange, the world’s largest granular material. [PDF]

, 2018
Tidewater glacier fjords are often filled with a collection of calved icebergs, brash ice, and sea ice. For glaciers with high calving rates, this “m ́elange” of ice can be jam-packed, so that the flow of ice fragments is mostly determined by ...

Monitoring the Petermann Ice Island with TanDEM-X [PDF]

, 2012
This paper presents the processing of TanDEM-X acquisitions for the monitoring of the topography of the Petermann ice island. In this particular case the area under study is continuously moving and the acquisition geometry is changing, so the processing ...

Glaciological and marine biological studies at perimeter of Dronning Maud Land, Antarctica [PDF]

The author has identified the following significant results. A nearly complete map of the Dronning Land coastline from 10 deg W to 29 deg E was produced. Based on this, it was determined that for the past 20 years, the minimum calving rate from this part
