New data can help better understand glaciers
On February 20, a dedicated team of researchers presented a new high-resolution calving front dataset from 149 glaciers in Svalbard, spanning from 1985 to 2023. This innovative dataset, featured in Earth System Science Data, offers an important tool.....»»
Milk analysis reveals "invisible" disease in dairy cows
Researchers have developed a new method of detecting a metabolic disease that affects dairy cows after calving. The aim is to determine whether cows are at risk of contracting the disease before they actually become sick......»»
Deciphering the association between uterine microbiota and fertility in dairy cows
Reduced fertility prolongs the interval from calving to conception in dairy cows, resulting in significant economic losses to dairy farms. Up to 25% of cows are culled due to reproductive failure, and this accounts for a larger proportion than that c.....»»
Predicting calving problems before insemination
A small percentage of cows will experience problems when calving and breeders would like to know which cows are at risk. Using the vast dataset of the Dutch cattle breeding company CRV, computer scientists at the University of Groningen used artifici.....»»
Underwater tsunamis created by glacier calving cause vigorous ocean mixing
Scientists on a research vessel in Antarctica watched the front of a glacier disintegrate and their measurements "went off the scale." As well as witnessing disruptions on the ocean surface, they recorded "internal" underwater tsunamis as tall as a h.....»»
Recent studies find previously unknown loss of Antarctic ice
New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the continent is changing......»»
Benefits of early calving are increasing due to late winter warming
On rangelands of the Western U.S., calving in late winter instead of spring maximizes calf growth (weight) by supplying high-quality forage when its most needed, according to a study by the United States Department of Agriculture (USDA), Agricultural.....»»
Scientific team uncovers additional threat to Antarctica"s floating ice shelves
Glaciologists at the University of California, Irvine and NASA's Jet Propulsion Laboratory have examined the dynamics underlying the calving of the Delaware-sized iceberg A68 from Antarctica's Larsen C ice shelf in July 2017, finding the likely cause.....»»
New study finds emperor penguins increasingly threatened by climate change
A new study published today in Global Change Biology provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice los.....»»
Underwater seismometer can hear how fast a glacier moves
Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake......»»
New model simulates the tsunamis caused by iceberg calving
A team of scientists has developed a new model for simulating both iceberg calving and the tsunamis that are triggered as a result. Their method can help improve hazard assessment in coastal areas and refine the empirical calving models used to evalu.....»»
Slushy iceberg aggregates control calving timing on Greenland"s Jakobshavn Isbræ
Shortly before Jakobshavn Isbræ, a tidewater glacier in Greenland, calves massive chunks of ice into the ocean, there's a sudden change in the slushy collection of icebergs floating along the glacier's terminus, according to a new paper led by the C.....»»
Revealing complex behavior of a turbulent plume at the calving front of a Greenlandic glacier
For the first time, scientists have succeeded in continuous monitoring of a subglacial discharge plume, providing a deeper understanding of the glacier-fjord environment......»»
Satellite captures detaching iceberg in near-real time
NASA's ICESat-2 satellite recorded the cleaving of a 315-billion-ton iceberg from Amery Ice Shelf in 2019, as well as years of subtle cracking and splitting prior to the calving event......»»
Greenland ice loss may have begun as early as the mid-"80s
The amount of snow falling on Greenland's glaciers may have been less than the water lost through icebergs calving and melting since at least the mid-1980s, a study of almost 40 years of satellite images has revealed......»»
ICESat-2 satellite reveals shape, depth of Antarctic ice shelf fractures
When a block of ice the size of Houston, Texas, broke off from East Antarctica's Amery Ice Shelf in 2019, scientists had anticipated the calving event, but not exactly where it would happen. Now, satellite data can help scientists measure the depth a.....»»
Gray whales learn daring feeding strategy in Puget Sound: Digging for ghost shrimp at high tide
Every spring, a small group of about a dozen gray whales pauses along an epic migration from calving lagoons in Baja California to their feeding grounds in the Arctic. They travel more than 170 miles off their coastal migration route, to stop off in.....»»
Rumen additive and controlled energy benefit dairy cows during dry period
Getting nutrition right during a dairy cow's dry period can make a big difference to her health and the health of her calf. But it's also a key contributor to her milk yield after calving. New research from the University of Illinois shows diets cont.....»»
Beluga whistles and clicks could be silenced by an increasingly noisy Arctic Ocean
Under the sea ice, the Arctic Ocean is one of the quietest places on Earth. But it can be very noisy when the ice is forming and breaking up or during storms and when glaciers are calving......»»
