Abstract Our understanding of the geological evolution mid‐ocean ridges in response to tectonic reconfigurations and associated mantle processes is hampered by a lack exploration off‐axis areas. A notable exception Reykjanes Ridge, where multibeam bathymetry, magnetics, gravity surveys have been conducted up ∼150 km from ridge axis. Previous work shows that has undergone major reorganization following changes spreading direction, resulting progressive formation then elimination transform...
The Vesturdjúp Basin is located at the northeastern edge of Irminger Sea, bordered by southern Greenland to west, Denmark Strait and Iceland north, Reykjanes Ridge east. To south, it opens into North Atlantic Ocean. basin’s bathymetry characterized large sediment rafts shaped intense bottom-water currents, a distinctive ocean floor fabric, numerous cone-shaped volcanoes1. In summer 2024, Meteor Expedition M201 explored seamounts Basin1. addition comprehensive geological...
Submarine explosive volcanism poses significant hazards to coastal communities, infrastructures, and marine air traffic. However, our understanding of the mechanisms, frequencies, distributions submarine eruptions is limited due their inaccessibility. This observational gap particularly critical for shallow environments, where interplay between magma seawater can lead violent that may trigger destructive tsunamis, pyroclastic surges, extensive pumice rafts, large airborne ash plumes. In this...
Abstract Sand ridges are primarily associated with tide‐ and storm‐dominated continental shelves, as documented in various studies. However there is a knowledge gap regarding the development presence of such features semi‐enclosed bays non‐tidal intra‐continental seas. In Puck Bay area, part Gulf Gdańsk southern Baltic Sea, field large sand ridges, aligned obliquely to shoreline, present at water depths ranging between 5 m 27 m. The extend up 5,000 length 250–350 width, following general...
Abstract Mapping and sampling four sections of the slow‐spreading Reykjanes Ridge provide insight into how tectonic volcanic activity varies with distance from Iceland plume. The studied areas are characterized by significant variations in water depth, lava chemistry, crustal thickness, thermal structure, ridge morphology. For each study area, fault pattern dimension, strain, seamount morphology, density inferred 15 m‐resolution bathymetry. These observations combined geochemical analysis...
During RV MS Merian expedition MSM75, an international, multidisciplinary team explored the Reykjanes Ridge from June to August 2018. The first area of study, Steinahóll (150–350 m depth), was chosen based on previous seismic data indicating hydrothermal activity. sampling strategy included ship- and AUV-mounted multibeam surveys, Remotely Operated Vehicle (ROV), Epibenthic Sledge (EBS), van Veen grab (vV) deployments. Upon returning during final days vent sites were discovered using ROV...
<title>Abstract</title> <bold>Submarine explosive volcanism presents significant hazards to coastal communities and infrastructure, yet its formation mechanisms occurrences remain poorly understood. We document widespread on the Northern Reykjanes Ridge using high-resolution seismic, bathymetric, seafloor imagery. The data reveal low width-height ratio volcanoes with stratified, outward-dipping reflections extensive volcaniclastic aprons overlying a glacial erosion unconformity, indicating...
The geology of the Reykjanes Ridge reflects variations in style crustal accretion related to mantle plume processes and tectonic reconfigurations. Following a ~30° change spreading direction, ridge segments progressively reassumed linear orientation under influence regional melting anomaly. This process is incomplete, with ongoing reorganization along southernmost part ridge. We investigate impacts this on propagation, seafloor morphology, structural fabrics using combination geophysical...
The Reykjanes Ridge is a segment of the slow-spreading Mid-Atlantic interacting with Iceland plume. 900 km long consists in &#8220;en echelon&#8221; axial volcanic ridges. They are typically 3-6 wide, 20-30 long, 200-500 m high, and overlap each other over distance of, on average, 1/3 their length. &#160;The ridge AVRs have been subject several studies base numerous models evolution. However, most these based bathymetry resolution > 20 sidescan data 5 m, no geochemical...

&lt;p&gt;The Reykjanes Ridge is a 900 km long oblique slow-spreading ridge, formed by individual &amp;#8220;en echelon&amp;#8221; axial volcanic ridges (AVR), directly under the influence of Iceland hotspot. From Peninsula to Bight fracture zone, shows variations in lava chemistry, crustal thickness, thermal structure and ridge morphology, which has been attributed this influence. Our study focuses on four areas mapped sampled during cruise MSM75 2018. The northern area...
&lt;p&gt;It is accepted that during the Last Glacial Maximum (LGM), about 21,000 years ago, head of Icelandic ice sheet was extending on a shelf area Iceland plateau, beyond present-day coastline island. Attempts at locating edge were made many times, mainly basis recognition end moraines and other marginal glacial landforms submerged parts plateau. There is, as yet, no full agreement exact reconstruction extent LGM. Both thermodynamic models discovered around indicate has slipped...
&lt;p&gt;The Reykjanes Ridge is a spreading center that presents an opportunity to track the dynamic formation of structural and volcanic features at asymmetric slow-spreading plate boundary.
