🧪⚒️ #NODSSUM cruise - On land, material & samples make their way back to home labs. And this morning we showed sonar images of barrels & photos taken by Ulyx flying at ~10 m above seafloor. Lots to do back in labs & offices. It was intense - good intense. Images: see copyright etc in thread
Copyright Flotte Oceanographique Française - Nodssum cruise. Swath of Ulyx sonar data (left) and close-up of the barrels at the seafloor, showing as bright spots (from box on the left) Copyright: Flotte Océanographique Française - Campagne NODSSUM. Barrel dumped at the seafloor at about 4700 m water depth Copyright: Flotte Océanographique Française - Campagne NODSSUM. Barrel at the seafloor showing a probable leak of unknown material - probably tar used to embed the waste in the barrels. Copyright: Flotte Océanographique Française - Campagne Nodssum. Sonar coverage during a dive of AUV Ulyx (gray background) covering a zone of approximately 6x3 km, with sonar swaths of about 400 m (horizontal stripes). The identified barrels shown as black dots line up along tracks followed by ships during barge dumping.

⚒️🧪🌊 How faults form @ the axis of mid-ocean ridges? Do fault parameters link to spreading rate, magma supply, volcanism? @jie-chen.bsky.social analyses high resolution bathymetry from deep-sea surveys, exploring temporal & spatial scales impacting fault growth:
