In celebration of Halloween, the European Space Agency (ESA) brings you this recent Copernicus Sentinel-2 satellite picture of the Halloween Crack in Antarctica.
First spotted on October 31, 2016, the Halloween Crack ranges from a location of Antarctica called McDonald Ice Rumples– which is where the underside of the floating ice sheet is grounded on the shallow seabed. This pinning point slows the circulation of ice and fractures the ice surface.
The Halloween Crack, which is currently stable, runs adjacent to the more precarious suggestion of the Brunt Ice Shelf. This idea of the shelf is hanging by a thread– it is now just kept in location by a narrow strip of ice around 600 meters (2000 feet) long at the northern end of the long chasm cutting through the western and remaining eastern part of the ice rack.
Utilizing radar images from the Copernicus Sentinel-1 objective, this animation reveals the development of 2 ice fractures from September 2016 till mid-October 2019. The big gorge running northwards is called Chasm 1, while the split extending eastwards is described as the Halloween Crack.

It is anticipated to generate a huge iceberg of around 1750 square kilometers (675 square miles)if and when this prospective rupture point lastly offers method. For a size comparison, this is around two-thirds the size of the state of Rhode Island or over five times larger than the size of Malta.
Due to the fact that Ice racks float, when they calve icebergs the bergs do not actually contribute to sea-level rise. However, ice racks function as a brake on how quick the glaciers on the land flow to the sea. Antarcticas ice racks are deteriorating due to climate modification, leading to higher threats of more land ice winding up in the oceans. This would consequently add to sea-level rise, which is something arguably more frightening than Halloween.
In this episode of the Earth From Space program, the Copernicus Sentinel-1 objective takes us over fractures in the Brunt ice shelf, which depends on the Weddell Sea sector of Antarctica.
Routine monitoring by satellites with different observing abilities offers extraordinary views of events happening in remote regions like Antarctica, and how ice racks are coping in action to modifications in ice characteristics, air, and ocean temperature levels.
Utilizing radar images from the Copernicus Sentinel-1 mission, this animation shows the advancement of 2 ice fractures from September 2016 up until mid-October 2019. Due to the fact that Ice shelves drift, when they calve icebergs the bergs do not really add to sea-level increase. Antarcticas ice racks are deteriorating due to climate change, leading to higher threats of more land ice ending up in the oceans.
