The largest glacier calving event ever recorded took place on May 28, 2008, while Adam LeWinter and Director Jeff Orlowski were filming the Ilulissat Glacier, in Western Greenland, for the documentary film Chasing Ice. The calving event lasted 75 minutes and the glacier retreated 1.6 km (1 mile) across a calving face 5 km (3 miles) wide. The total height of the ice was about 915 m (3,000 feet), of which 90-120 m (300-400 feet) was visible above water, while the rest was underwater. As a tidewater glacier slowly slides toward the ocean, large pieces calve (break off) to form icebergs. Most tidewater glaciers calve above the surface resulting in a thunderous crash of ice into the ocean. Some tidewater glaciers calve underwater thus causing the iceberg to surge up to the surface from below. Water displaced during calving often produces huge waves or a local tsunami.
“It’s as if the entire lower tip of Manhattan broke off, except that the thickness, the height of it, is equivalent to buildings that are two and a half or three times higher.” — James Balog | Chasing Ice
