Annals of Glaciology, 2019 We present a highly detailed study of calving dynamics at Tunabreen, a tidewater glacier in Svalbard. A time-lapse camera was trained on the terminus and programmed to capture images every 3 seconds over a 28-hour period in August 2015, producing a ...

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 ...

Neurophysiology of Milk Ejection and Prestimulation in Dairy Buffaloes
Animals, 2022 The present review aims to integrate the anatomical characteristics of the mammary gland and the neurophysiology of milk ejection to understand the milking capacity of the water buffalo. Since one of the main uses of this species is milk production, this

Animal, 2017 Rearing quality dairy heifers is essential to maintain herds by replacing culled cows. Information on the key factors influencing the cost of rearing under different management systems is, however, limited and many farmers are unaware of their true costs.

Rapid iceberg calving following removal of tightly packed pro-glacial mélange
Nature Communications, 2019 Iceberg calving is a major contributor to Greenland’s ice mass loss. Pro-glacial mélange (a mixture of sea ice, icebergs, and snow) may be tightly packed in the long, narrow fjords that front many marine-terminating glaciers and can reduce calving by ...

Characteristics, recent evolution, and ongoing retreat of Hunt Fjord Ice Shelf, northern Greenland
Journal of Glaciology, 2023 Arctic ice shelves have declined over the past several decades, one of many indications of a rapidly changing cryosphere. Here we use a collection of off-nadir Landsat 8 images, a 1978 digital orthophotograph and photogrammetrically derived DEM ...

Calving Induced Speedup of Petermann Glacier
Journal of Geophysical Research: Earth Surface, 2019 This study assesses the response on ice dynamics of Petermann Glacier, a major outlet glacier in northern Greenland, to the 2012 and a possible future calving event.

Drivers of Recurring Seasonal Cycle of Glacier Calving Styles and Patterns
Frontiers in Earth Science, 2021 Calving is a crucial process for the mass loss of outlet glaciers draining the Greenland ice sheet. Moreover, due to a lack of observations, calving contributes to large uncertainties in current glacier flow models and projections.

PLoS ONE, 2018 Lactation records from 396,534 pedigree Holstein and Holstein-Friesian primiparous cows from 6,985 UK milk recorded herds, calving for the first time during the period between the 1st of January 2006 and the 31st of December 2008, were examined in order ...

Detection of Glacier Calving Margins with Convolutional Neural Networks: A Case Study
Remote Sensing, 2018 The continuous and precise mapping of glacier calving fronts is essential for monitoring and understanding rapid glacier changes in Antarctica and Greenland, which have the potential for significant sea level rise within the current century.
