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

New 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,

Larsen C Ice Shelf in the Western Weddell Sea is a Hotspot for Export Production in the Antarctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The Southern Ocean accounts for >30% of the global ocean CO2 sink as a result of its solubility and biological pumps. To investigate the biological pump near Larsen C Ice Shelf (LCIS) in the Southern Ocean's western Weddell Sea, we measured the concentrations and nitrogen isotope ratios of nitrate, ammonium, and particulate organic nitrogen ...

Three-dimensional modelling of calving processes on Johnsons Glacier, Livingston Island, Antarctica.

, 2010
Iceberg calving is an important mass loss mechanism from ice shelves and tidewater glaciers for many mid and high-latitude glaciers and ice caps, yet the process is not well represented in prognostic models of ice dynamics.

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.

Seismic Clues Reveal the Mechanisms Behind Iceberg Calving

Eos, 2016
Scientists combine models and video footage of iceberg calving to analyze the potential of seismology to unravel physical processes behind the breakup of ice sheets.

Massive Antarctic Icebergs May Calve at Random

Eos
The first analysis of extreme calving events in Antarctica finds no correlation with climate change, highlighting the significance of common, smaller calving events for ice loss and instability.

Glacial earthquake-generating iceberg calving in a narwhal summering ground: The loudest underwater sound in the Arctic?

, 2022
Measurements of underwater sound are still scarce in the rapidly changing Arctic. Tele-seismically detectable glacial earthquakes caused by iceberg calving have been known for nearly two decades but their underwater sound levels remain undocumented. Here,

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 ...

A viscoelastic phase-field model for iceberg calving

Iceberg calving accounts for around half of the ice lost annually from Antarctica, but realistic representation of fracture and calving in large-scale ice sheet models remains a major unsolved problem in glaciology. We present a new phase-field viscoelastic model for fracture that simulates the slow deformation of ice and the distribution and evolution
