Post‐Miocene Transtensional Opening of the Northern Red Sea
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

Bathymetry mapping with empirical bathymetry method based on sentinel application platform case study: Bawean Island, Central Java [PDF]
Bathymetry information is an important requirement for the marine and fisheries sector in Indonesia. However, the acquisition of information is done in the traditional way, namely surveys using single/multibeam echosounder devices carried by ships.

A recent multibeam bathymetry survey in the Galápagos archipelago revealed a novel observation between the islands of Santa Cruz and Santiago: a steep flexural moat formed between two volcanic flows, nearly 50 m deep and about 500 m wide.

Abstract Mid‐ocean ridges, the Earth's most extensive volcanic system, exhibit unique characteristics in sediment‐dominant environments. Thick sediment cover insulates the crust and channels fluid along pathways that can lead to the formation of distinct crustal alteration patterns, exceptionally large mineral deposits, and specialized chemosynthetic ...

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

Abstract Sedimentary archives of tropical cyclones have been primarily developed in back barrier settings and karst basins at low to mid‐latitude sites in the Atlantic. Here, a unique record of high‐latitude storms is presented from Skan Bay, Unalaska in the Eastern Aleutian Islands. Storm‐induced coarse deposits in a 20.5 m composite sediment core are

Abstract Serpentinite plays a major role in the geodynamics of subduction zones. However, the processes by which serpentinite is incorporated into accretionary complexes, and the extent to which it interacts chemically and physically with accretionary lithologies, remain unclear.

Flood Inundation Modeling Using the Surface Water Ocean Topography Mission
Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

Abstract Hydrothermal fluid flow not only shapes mineral deposition on the ocean floor but also creates ecological niches by altering temperature and energy availability. In these niches, microbial life thrives and has an additional, often unrecognized impact on mineral formation. In a newly discovered vent field at water depths of 100–200 m off Milos,

Analyzing Archive Transit Multibeam Data for Nodule Occurrences
We show that analyzing archived and future multibeam backscatter and bathymetry data, in tandem with regional environmental parameters, can help to identify polymetallic nodule fields in the world’s oceans.
