An enormous iceberg off the coast of Iceland unexpectedly emerged from the depths, tipped onto its side, and generated tsunami-like waves across a glacial lagoon. This rare occurrence may have resulted from underwater calving, a process where ice from glaciers detaches and rises due to buoyancy. Scientists have recorded similar incidents of iceberg capsizing that can produce substantial surface waves. In Alaska, surfers Garrett McNamara and Kealii Mamala have surfed waves generated by glaciers that reached heights of up to 25 feet. The footage from Iceland underscores the formidable and erratic dynamics of calving ice, with ongoing glacier activity influencing waterways.

Transcript
00:00A giant iceberg suddenly surged upward in an Icelandic glacier lagoon.
00:04The massive block of blue-white ice began rolling onto its side.
00:08As it flipped, water poured from the newly exposed surface.
00:12The movement sent tsunami-like waves racing across the lagoon.
00:16The unusual event may have been caused by submarine calving.
00:19That happens when ice breaks free from the submerged part of a glacier.
00:23Buoyancy can then send the underwater ice rapidly toward the surface.
00:27Newly calved icebergs can also become unstable and suddenly capsize.
00:32Scientists say these movements can generate large surface waves.
00:36Similar iceberg activity has been documented at Alaska's Columbia Glacier.
00:40In Iceland, the dramatic flip created a striking pulse of water.
00:44The waves spread outward as the iceberg settled into a new position.
00:49Glacier-generated waves have even attracted experienced surfers in Alaska.
00:53Some have ridden waves reaching up to 25 feet.
00:57But an unexpected iceberg flip remains highly unpredictable.
01:00The footage shows how powerful and unusual glacier physics can be.
