A substantial quantity of sedimentary sand bodies, including ridges, waves, and ripples, have been developed off the southwest coast Hainan Island, China, with submarine ridges exhibiting most considerable development scale. Determining distribution, morphology, evolutionary characteristics is crucial for exploiting marine resources investigating engineering geological hazards. comprehensive assessment study area was conducted utilizing survey techniques, single-beam echo sounding,...
The remotely operated vehicle (ROV), a vital deep-sea platform, offers key advantages, including operational duration via continuous umbilical power, high task adaptability, and zero human risk. It has become indispensable for scientific research marine engineering. To enhance surveys of cobalt-rich crusts (CRCs) on complex seamount terrains, the 4500-m-class Haima ROV integrates advanced payloads, such as underwater positioning systems, multi-angle cameras, multi-functional manipulators,...
For the detection of deep-sea natural gas hydrates, it is very important to accurately detect 13CO2/12CO2 isotope ratio dissolved in seawater. In this paper, a sensor investigated, which uses tunable diode laser absorption spectroscopy (TDLAS) technique at 4.3 μm. The proposed consists mid-infrared interband cascade (ICL) operating continuous wave mode, long optical path multi-pass cell (MPGC) 24 m, and mercury cadmium telluride (MCT) detector. Aiming problem strong intensity two lines 13CO2...
Abstract A large number of sand waves are developed on the seafloor off coast Dongfang, Hainan Island. This paper analyzes geophysical characteristics active submarine synthetically by using multi-beam echo-sounding(MBES), side-scan sonar(SSS), sub-bottom profiler (SBP), and single-channel seismic(SCS) data, discusses distribution characteristics, migration mechanism, activity, morphologic evolution waves. The results show confirm that there significant spatial differences in scale waves,...
