Calving dynamics at Jakobshavn Isbrae (Sermeq Kujalleq) controlled by local geometry: insights from a 3D Stokes calving model [PDF]

Journal of Glaciology
We present the first simulations of Jakobshavn Isbrae (Sermeq Kujalleq), west Greenland, using a 3D Stokes calving model that permits unrestricted advance and retreat.

Effect of restricting silage feeding prepartum on time of calving, dystocia and stillbirth in Holstein-Friesian cows [PDF]

Irish Veterinary Journal, 2007
A study was carried out to investigate the effect of restricting silage feeding on time of calving and calving performance in Holstein-Friesian cows. In the treatment group (n = 1,248 cows, 12 herds) silage feeding commenced in the evening (17:00 to 20 ...

Glacio-limnological interactions at lake-calving glaciers [PDF]

, 2012
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response.

Distinguishing subaerial and submarine calving with underwater noise

Journal of Glaciology, 2022
Iceberg calving is one of the major mechanisms of ice loss from tidewater glaciers and ice sheets, but obtaining accurate estimates of ice discharge that are both continuous and accurate is a challenging task.

Calving rates at tidewater glaciers vary strongly with ocean temperature [PDF]

, 2015
TerraSAR-X data were provided by DLR (project OCE1503), and funded by the Conoco Phillips-Lundin Northern Area Program through the CRIOS project (Calving Rates and Impact on Sea level). A.L. and S.B.

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.

Toward Numerical Modeling of Interactions Between Ice-Marginal Proglacial Lakes and Glaciers

Frontiers in Earth Science, 2020
Global climate change is evidently manifest in disappearing mountain glaciers and receding and thinning ice sheet margins. Concern about contemporaneous proglacial lake development has spurred an emerging area of research seeking to quantitatively ...

A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics [PDF]

, 2010
We present results from numerical ice-flow models that include calving criteria based on penetration of surface and basal crevasses, which in turn is a function of longitudinal strain rates near the glacier front.

Processes of crevasse formation and the dynamics of calving glaciers : a study at Breiđamerkurjökull [PDF]

, 2009
A new model proposed by Benn et al. (2006, 2007) explains the dynamics of calving glaciers based on a new sliding law and a calving criterion modified from a crevasse depth model. In this thesis three key elements of this model are tested: 1) the role

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.
