![]() ![]() ![]() M.: High-resolution geomorphological studies of a Red Sea Rift segment in Hadarba Deep, EGU General Assembly 2023, Vienna, Austria, 24–, EGU23-13869,, 2023. We will present our geomorphological maps, analyses, and statistics that reveal a moderately faulted, ultra-slow spreading MOR segment in the Red Sea with a surprisingly large amount of magmatic extension and show implications for the formation history of this ridge segment.Īugustin, N., Le Saout, M., Schiebener, C. However, their sediment cover is below the vertical sub-bottom-profiler resolution of about 10 cm and thus might be only a few hundred years old or younger. Several younger lava flows show recent episodes of volcanism along the rift axis. The high-resolution hydroacoustic data of the used Kongsberg Hugin Superior AUV (operated by Fugro) revealed more than 100 individual lava flows with. ![]() A dome volcano with a 2.5 km diameter and an average height of 300 m dominates the mapped area but has been inactive for at least ~8.4 ka. He is responsible for the HUGIN and MUNIN Autonomous Underwater Vehicles and. The oldest lava flows are buried under 3-4 m of sediment, indicating ages of up to 28 ka. With productivity in mind Kongsberg has introduced the HUGIN Superior. The high-resolution hydroacoustic data of the used Kongsberg Hugin Superior AUV (operated by Fugro) revealed more than 100 individual lava flows with different stages of sedimentation. This area's total spreading rate of about 12 mm per year is defined as ultra-slow spreading. More so, the HUGIN Superior is the complete system. During the first AUV surveys of the Red Sea rift in Spring 2022, we collected multibeam bathymetry, backscatter, sub-bottom, and water column data over a 9 km long ridge segment in the Hadarba Deep between 22.49°N and 22.56°N to investigate the volcano-tectonic processes of this mid-ocean ridge. The mid-ocean rift in the Red Sea is recently regaining attention in the geosciences due to the possibility of investigating this young ocean in more detail than ever by state-of-the-art methods and modern deep-sea instrumentation. ![]()
