New time-lapse videos of Earth’s glaciers and ice sheets as seen from space – spanning nearly 50 years – are providing scientists with new insights into how ...

2019年3月27日 · A new animation from NASA software engineers, based on finely tuned computer models, reveals how massive ice sheets that once sprawled across Canada, Greenland and Antarctica thickened and thinned over time. Their …

Science writer Dr Gabrielle Walker has been obsessed with ice ever since she first set foot on Arctic sea ice. In this programme she searches out some of the secrets hidden deep within the ice...

2017年4月21日 · A team of scientists has put together photographic "proof" of climate change, revealing time-lapse photo couplets, or before/after images, of retreating glaciers.

Our cameras record changes in the glaciers every hour, year-round during daylight, and yield approximately 8,000 frames per camera per year. We combine these images into stunning time-lapse videos that reveal how quickly climate change is transforming large regions of our planet.

2019年12月9日 · Using images from the Landsat mission dating back to 1972 and continuing through 2019, glaciologist Mark Fahnestock of the University of Alaska Fairbanks, has stitched together six-second time-lapses of every glacier in Alaska and the Yukon. The videos clearly illustrate what's happening to Alaska's glaciers in a warming climate.

2015年11月26日 · The timelapse view makes it easier for the human eye to follow glacier flow and detect changes. The Baltoro animation, for example, highlights how fast and steadily the glacier is flowing without changing the position of its front, while the Panmah image sequence shows several surging glaciers flowing into each other.

While many studies currently exist that are documenting changes to glaciers at Mount Rainier, one of the best ways to witness the dynamic nature of a glacier is with time-lapse photography. In 2018, the National Park Service’s North Coast and Cascades Research Learning Center funded the procurement of two field-deployable solar-powered high ...

Time-lapse movement of a glacier in northern Canada. NARRATOR: To document the movement of a glacier, scientists used time-lapse photography. A camera was set to take a photograph of this glacier in northern Canada once each day for 77 days. This picture shows the glacier's position on the first day.

2019年12月9日 · New time-lapse videos of Earth’s glaciers and ice sheets as seen from space – some spanning nearly 50 years – are providing scientists with new insights into how the planet’s frozen regions are changing.
