In deep time (i.e., >100 Million years ago), the number of methods that can be used to reconstruct global sea level is limited and mostly restricted to observations of changes in fossils and sediment types that mark the moving position of the shoreline. However, these methods simultaneously measure global sea-level change and local uplift or subsidence at the observation point. A new study published in Gondwana Research instead reconstructs global sea level change from estimates of past continental flooding. Flooding measurements represent averages across large continental areas, which makes them less sensitive to regional modifications. The new study demonstrates the accuracy of this method over the past 520 million years and its potential use for even deeper time.

NASA’s TESS mission has found two rocky worlds orbiting the relatively bright, red dwarf star HD 260655, only 33 light-years away. The new planets, HD 260655 b and HD 260655 c, are among the closest-known rocky planets yet found outside our solar system that astronomers can observe crossing the faces of their stars.

The Centre for Earth Evolution and Dynamics is pleased to announce our series "The Wilson Cycle." The four videos follow CEED researchers to western Norway where they share insights into this fundamental process that explains the formation of oceans and mountains, and more. Every two weeks during summer 2022 we released a video below and via our YouTube channel

The Jurassic Earth was very different from today - atmospheric CO2 was higher, long-term climate was warmer, and there were no permanent polar ice-caps. The supercontinent Pangea was breaking apart, leading to changes in the configuration of the landmasses, oceans, and seaways. Using geochemical signals from fossilized marine animals, a new study in Palaeo3 looked at how the ocean currents and climates changed in the European and Arctic regions during this Greenhouse period of Earth’s history.
