Operational Near Real Time Global Riverine Sediment Flux Estimates From Space
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We present global estimates of riverine sediment flux derived from an open‐source suite of algorithms using the Harmonized Landsat Sentinel (HLS) and discharge products. We estimated Sediment Concentration (suspended sediment concentration [SSC]) via neural networks, trained and tested on matchups of in situ and HLS data, obtaining a median ...

Inside the ice shelf: using augmented reality to visualise 3D lidar and radar data of Antarctica
The Photogrammetric Record, Volume 34, Issue 168, Page 346-364, December 2019., 2019 From 2015 to 2017, the ROSETTA‐Ice project comprehensively mapped Antarctica's Ross Ice Shelf. The campaign imaged the ice‐shelf surface with lidar and its internal structure with ice‐penetrating radar. The first augmented reality (AR) visualisation of the Antarctic Ice Sheet, using the Microsoft HoloLens, is presented.
