Monitoring volcanic activity with distributed acoustic sensing using the Tongan seafloor telecommunications cable
The devastation caused by the January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano (HTHH) in the Tongan archipelago reminded us of the...

Low-noise, low-power-consumption seafloor vector magnetometer
The seafloor vector magnetometer is an effective tool for marine geomagnetic surveys and seafloor magnetotelluric (MT) detection. However, the noise,...

Physical-mechanical properties of sediments and their correlation with near seafloor seismic amplitude in the Liwan canyon area, northern South China Sea
Before the implementation of offshore oil and gas exploitation, it is essential to understand the various factors that influence the stability of...
-
A preliminary study on the acoustic properties of seafloor sediment in the southern U-boundary of the South China Sea
The acoustic properties of seafloor sediment are essential parameters in the exploration of marine resources, ocean scientific research and ocean...

In Situ Detection and Seafloor Observation of the Site F Cold Seep
The in situ detection and seafloor observation of the Site F cold seep began after its discovery. Research on deep−sea cold seep systems often begins...
-
Effect of Temperature on the Acoustic Reflection Characteristics of Seafloor Surface Sediments
Because the sound speeds of seawater and seafloor sediment both increase with temperature, the influence of temperature on the bottom reflection...

Geological characteristics of the Qiaoyue Seamount and associated ultramafic-hosted seafloor hydrothermal system (∼52.1°E, Southwest Indian Ridge)
Hydrothermal vent incidence was once thought to be proportional to the spreading rate of the mid-ocean ridges (MORs). However, more and more studies...

Differences of polygonal faults related to upper Miocene channels: a case study from the Beijiao sag of Qiongdongnan basin, South China Sea
Deep-water coarse-grained channels are embedded within a polygonal fault tier, and the polygonal faults (PFs) present non-polygonal geometries rather...
