Swath Multibeam Bathymetry Survey data from cruise JC288 to the Mississippi Canyon and East Coast USA Canyons (March-April 2026)

Peter J Talling, Edward Keavney, Sanem Açıkalın, Morelia Urlaub et autres

Swath multibeam surveys of seafloor bathymetry data were collected in 3 main areas: The Mississippi Canyon, Hatteras Outer Bank Sediment Wave field, and four submarine canyons on the US East Coast, from March-April 2026 as part of the James Cook (JC288) research …

Swath multibeam bathymetry, Sound Velocity Profiler and Sub-Bottom Profiler data, and sediment core locations from RRS James Cook (Cruise Number JC288) from Mississippi Canyon, Hatteras Sediment Waves, and East Coast Canyons from March-April 2026 (NCEI Accession 0317413)

Peter Talling, Edward Keavney, Sanem Açıkalın, Morelia Urlaub et autres

Data collected from March-April 2026 onboard the RRS James Cook. Data includes swatch multibeam bathymetry, Sound Velocity Profiler, Sub-Bottom Profiler, and sediment core locations. Data were collected from two areas of the Mississippi Canyon, an area of sediment waves in International Waters …

Etna’s submarine flank morphology and basement: new insight from microbathymetry and revised structural interpretation

Sylvain Mayolle, Morelia Urlaub, Thor H. Hansteen, Pilar Madrigal et autres

Mount Etna, one of Earth's most active volcanoes, rises to an elevation of 3,400 meters. Its eastern flank extends seaward, descending to approximately 1,500 meters below sea level and creating a total vertical relief of nearly 5,000 meters. While it is known …

Shallow structural deformation associated with the 1956 Amorgos Earthquake, Aegean Sea - an investigation from 3D seismic reflection data

Effrosyni Varotsou, Jens Karstens, Gareth Crutchley, Morelia Urlaub et autres

The Santorini–Amorgos Tectonic Zone in the South Aegean Sea is a major hotspot for marine geohazards, where strong earthquakes, pronounced deformation, and tsunamis interact within an actively extending back-arc setting. The 1956 tsunamigenic Mw 7.5 Amorgos earthquake stands out as the largest …

The influence of porosity and microstructure on the fracture toughness of basalts from Mt. Etna: laboratory measurements

Leonie Papanagnou, Séverine Liora Furst, Corentin Noël, Michael John Heap et autres

Mode I fracture toughness, KIc, is a key measure of rock strength. In volcanology, KIcis particularly relevant for dike propagation, as it quantifies the critical stress intensity factor required for fracture propagation under tensile stress. KIc has been extensively studied for rock …

Impact of topography and water load on magma propagation modelling

Séverine Liora Furst, Lorenzo Mantiloni, Francesco Maccaferri, Fiene Stoepke et autres

Coastal and submarine volcanoes are characterized by complex topographies, a significant portion of which lies below sea level, complicating efforts to fully quantify how surface geometry influences magma transport. Understanding the coupling between topography, stress fields, and magma propagation is essential for …

Global land-to -sea geomorphometry of 237 volcanic islands

Elisa Klein, Morelia Urlaub

The study of volcanic islands is often divided at the coastline into terrestrial and submarine due to the respective methodological requirements. For many scientific objectives especially in volcanic hazard assessment, it is important to consider the entire edifice. Here, we provide a …

Sediment echosounder raw data (Atlas Parasound P70 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM132

Christian Berndt, Morelia Urlaub, Janine Berndt

Sediment echosounder data using the Teledyne Reson PARASOUND DS P-70 parametric sub-bottom profiler were recorded during RV MARIA S. MERIAN cruise MSM132 offshore Catania (Italy) to Heraklion (Greece) in the Mediterranean Sea. Data were acquired between 06 December 2024 and 01 January …
