Melt-under-cutting and buoyancy-driven calving from tidewater glaciers: new insights from discrete element and continuum model simulations

Journal of Glaciology, 2017
The simple calving laws currently used in ice-sheet models do not adequately reflect the complexity and diversity of calving processes. To be effective, calving laws must be grounded in a sound understanding of how calving actually works.

Calf management practices and associations with herd-level morbidity and mortality on beef cow-calf operations

Animal, 2016
The objective of this study was to investigate calf management practices on beef cow-calf operations and determine associations with herd-level morbidity and mortality of pre-weaned calves.

Underwater Ice Terrace Observed at the Front of Glaciar Grey, a Freshwater Calving Glacier in Patagonia

Geophysical Research Letters, 2019
Underwater ice geometry at the front of calving glaciers provides crucial information for calving and underwater melting. In this study, we present ice geometry captured by operating a side‐scanning sonar near the front of Glaciar Grey, a freshwater ...

Glacier Calving in Greenland

Current Climate Change Reports, 2017
In combination, the breakaway of icebergs (calving) and submarine melting at marine-terminating glaciers account for between one third and one half of the mass annually discharged from the Greenland Ice Sheet into the ocean.

Relationship between Conception Date and Latitude in Muskoxen

Rangifer, 1997
It has been suggested that muskoxen calve earlier with increasing latitude but the available data do not seem to have been thoroughly analyzed. Therefore, estimated conception dates (K=657) from a wide range of latitudes were compared.

Genome-wide association studies and genomic prediction of breeding values for calving performance and body conformation traits in Holstein cattle

Genetics Selection Evolution, 2017
Our aim was to identify genomic regions via genome-wide association studies (GWAS) to improve the predictability of genetic merit in Holsteins for 10 calving and 28 body conformation traits.

Bathymetric controls on calving processes at Pine Island Glacier

The Cryosphere, 2018
. Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. Its ice loss has substantially increased over the last 25 years through thinning, acceleration and grounding line retreat.

Transition Between Mechanical and Geometric Controls in Glacier Crevassing Processes

Geophysical Research Letters
Herein, fast fracture initiation in glacier ice is modeled using a Material Point Method and a simplified constitutive law describing tensile strain softening.

Modelled frontal ablation and velocities at Kronebreen, Svalbard, are sensitive to the choice of submarine melt rate scenario

Journal of Glaciology
Both submarine melt and calving are important for the overall mass balance of marine-terminating glaciers, but uncertainty is rife with regards to the magnitude of the processes. Modelling allows for these processes to be investigated without the need to

Calving distribution of Alaska's Steese-Fortymile caribou herd: A case of infidelity?

Rangifer, 1986
The Steese-Fortymile caribou (Rangifer tarandus granti) herd has changed its calving distribution frequently during the past 30 years. A «traditional» calving area, used for decades, west of the Steese Highway (Preacher Creek) was abandoned after 1963 ...
