Woo! Our study led by Andrew Hoffman (@LamontEarth) uses swath radar maps to identify huge subglacial valleys beneath the West Antarctic Ice Sheet. We see Yosemite-scale U-shaped valleys (> 1 km relief!), arêtes and hanging valleys typical of alpine glaciation
The work of GSA Members Emma Heitmann, Susannah Morey & Megan Mueller was recently published in @NatureGeosci, entitled Scars of tectonism promote ice-sheet nucleation from Hercules Dome into West Antarctica. Read more: https://t.co/DgkCaTnBCp

And what's exciting to me is that these U-shaped valleys are oriented in a way that suggests they formed as fault-bounded basins during West Antarctic rifting...meaning that these paleo-alpine glacier networks appear to be controlled by the larger tectonic evolution
Jackson School postdoc @MegoMueller and collaborators provide an unprecedented look at subglacial topography in East Antarctica and how it influences the evolution of ice sheets in the continent's west.
Sedimentary basin folks, please consider submitting an abstract to our session dedicated to the Tectonics of Sedimentary Basins at the 2024 SEPM International Sedimentary Geosciences Congress
Are you doing exciting work with detrital heavy minerals? Submit to our session at GSA Connects 2023 @geosociety
Session T109 - Advances in Detrital Heavy Minerals:
Applications & Methods. @swmgeorge@ShayPRidl
We're excited about all the advances in the acquisition and application of detrital mineral datasets (modal counts, single grain isotopic and geochemical data, methodological advancements, etc.). We're looking forward to invited talks by @GeoKate88 and Sergio Ando!
