It’s not you, it’s me(lange): ice shelf break-up triggered by mélange and sea-ice loss

Jenny Arthur May 21, 2021

Between March and May 2007, a total of ~2,445 km2 (equivalent to over 17 football pitches) of ice mélange (a mixture of sea-ice types, icebergs and snow) and part of Voyeykov Ice Shelf in East Antarctica rapidly broke up. Observations of the timing and triggers of such events are relatively rare in East Antarctica, compared to ice shelves on the Antarctic Peninsula. Recent work highlights the impo ...[Read More]

The Supercontinent Cycle

Tobias Rolf and edited by Kiran Chotalia May 19, 2021

From orbital, to climatic, to tectonic evolution, many aspects of the Earth’s dynamics feature high degrees of cyclicity and episodicity, which can give us important insights into how the Earth’s works. The supercontinent cycle is an example capturing the Earth’s grandest scales and this week EGU geodynamics blog editor Tobias Rolf takes a closer look at it. Pangaea. This is a familiar term to eve ...[Read More]
