EarthByte publicity for Oblique rifting of the Equatorial Atlantic paper

by

Summary FigureCongratulations to EarthByte’s Sascha Brune and Christian Heine (now at Shell in The Hague) who made it to the Sydney Uni front page with a media piece on “How the world missed out on a Saharan Atlantic ocean”, attracted international media attention and were chosen as a “Research Focus” in the current volume of Geology for their paper: Oblique rifting of the Equatorial Atlantic: Why there is no Saharan Atlantic Ocean. Well done! … Read more…

Geochemistry, Geophysics, Geosystems – Community infrastructure and repository for marine magnetic identifications

by

magnetic_picks_globeMagnetic anomaly identifications form the primary data set from which the age of the oceanic lithosphere can be determined, a critical component of reconstructing the seafloor spreading history of ocean basins. This data is now available as part of an open source, community-driven online repository that contains quality-checked magnetic anomaly picks, organised by ocean basin and publication source.
