The seaward side of the Ronne-Filchner ice shelf is divided into Eastern (Filchner) and the larger Western (Ronne) sections by Berkner Island. The whole ice shelf covers some 430,000 kmĀ², making it the second largest ice shelf in Antarctica, after the Ross Ice Shelf.

It grows perpetually due to a flow of inland ice sheets. From time to time, when the shearing stresses exceed the strength of the ice, cracks form and large parts of the ice sheet separate from the ice shelf and continue as icebergs. This is known as calving.

In this image, part of the Filchner section along the ocean is visible. A large iceberg can be seen here, with many other smaller icebergs visible nearby, all on the right side of the image.
