Serial and Parallel Testing Strategies for Johne's Disease: Effects on Milk Production Traits and Milk Income on New Zealand Dairy Cattle

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
The suboptimal accuracy of current diagnostic tests necessitates alternative testing strategies to improve the detection of Johne's disease. We studied parallel and serial testing strategies to quantify the association between milk production and Johne's disease status. For this, two commercial Johne's disease Enzyme‐Linked Immunosorbent Assay, ELISAs,

A Transient Coupled Ice Flow‐Damage Model to Simulate Iceberg Calving From Tidewater Outlet Glaciers

open access: yesJournal of Advances in Modeling Earth Systems, 2019
Iceberg calving, the detachment of an ice block at the glacier front, is the main process responsible for the dynamic mass loss from the ice sheets to the ocean.

Detailed Lacustrine Calving Iceberg Inventory from Very High Resolution Optical Imagery and Object-Based Image Analysis

open access: yesRemote Sensing, 2020
In the field of iceberg and glacier calving studies, it is important to collect comprehensive datasets of populations of icebergs. Particularly, calving of lake-terminating glaciers has been understudied.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

open access: yes, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

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

open access: yesNew 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 ...

Tidewater glacier response to individual calving events

open access: yesJournal of Glaciology, 2022
Tidewater glaciers have been observed to experience instantaneous, stepwise increases in velocity during iceberg-calving events due to a loss of resistive stresses.

Journey of an Arctic ice island [PDF]

open access: yes, 2016
In August 2010, a 253 km2 ice island calved from the floating glacial tongue of Petermann Glacier in Northwest Greenland. Petermann Ice Island (PII)-B, a large fragment of this original ice island, is the most intensively observed ice island in recent ...

Investigating the Effect of Internal Waves on Vertical Ice Melting Rates

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Polar ice sheets are losing mass as a result of ocean‐driven melting processes and thus affecting global climate and sea level. Understanding the relevant dynamics and interactions at the ice‐ocean interface is crucial to developing more accurate sea‐level rise projections, but key ocean processes have not yet been considered in detail.

Glacier monitoring using real-aperture 94 GHz radar

open access: yesAnnals of Glaciology, 2022
Close-range sensors are employed to observe glaciological processes that operate over short timescales (e.g. iceberg calving, glacial lake outburst floods, diurnal surface melting).

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]

open access: yes, 2007
A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...
