By flying ATM over the same swath of ground previously covered by ICESat, researchers can maintain a record of changes.In addition, the precise data from ATM’s navigation system can be fed to pilot displays in the cockpit or even electronically sent to the automatic pilot system, keeping the aircraft aligned with the planned survey track. This keeps the aircraft along the planned ATM survey swath and also benefits the other IceBridge instruments by minimizing aircraft roll and horizontal acceleration. || ", "hits": 61 }, { "id": 13349, "url": "https://svs.gsfc.nasa.gov/13349/", "result_type": "Produced Video", "release_date": "2019-10-21T10:00:00-04:00", "title": "Unusual Winds Drive a Small 2019 Ozone Hole", "description": "Every year, NASA and NOAA track the hole in the ozone layer over Antarctica as it grows to its annual winter maximum.

In a paper in April, Rignot's research group discussed the steadily increasing flow speeds of these glaciers over the past 40 years. This new study examines the other two lines of evidence.As glaciers flow out from land to the ocean, large expanses of ice behind their leading edges float on the seawater. The point on a glacier where it first loses contact with land is called the grounding line. Nearly all glacier melt occurs on the underside of the glacier beyond the grounding line, on the section floating on seawater. The Antarctic glaciers studied have thinned so much they are now floating above places where they used to sit solidly on land, which means their grounding lines are retreating inland.—>
