  • Accurate sea floor mapping: From multichannel seismic hydrophone

    Accurate sea floor maps are needed for many applications, such as geological studies, coastal safety, navigation, and climate changes, but have only been produced recently by utilizing digital multibeam technology, remotely operated vehicles, or diving in a submersible device. However, because of the cost of these operations, those maps are rare for areas that are not shallow and near the shore. The goal of this research is to investigate the feasibility of using marine seismic survey data for accurate sea floor mapping. Seismic survey data has been widely collected around the world by oil and gas companies for oil and gas exploration. The data used in this research is the multichannel marine seismic survey EW0008 in the western Atlantic Ocean obtained from the Earth Institute Marine Geoscience Data System at Columbia University. The Seismic Unix processing package from the Center of Wave Phenomena at Colorado School of Mines is used to process the EW0008 survey. By using the common midpoint gather to analyze the velocity of sound traveling between the ocean surface and floor, based on the hyperbolic move out assumption, we can precisely determine the velocity of sound to an accuracy of 1m/sec at 37.5m increment along the sail line, and determine the sea floor reflection time at 1ms time resolution. Therefore, the accuracy of sea floor mapping is approximately 0.1 percent of the water depth in this survey area.The research results show that the multichannel marine seismic survey data can be used for accurate sea floor mapping, achieving large scale sea floor coverage with an accuracy of approximately 0.1 percent. This project illustrated a creative use of the marine seismic survey data beyond its intended purposes and improved sea floor mapping accuracy and coverage significantly. It is a start of greater efforts to map Earth's sea floor.

    The magnetic dipole-dipole configuration adopted in sea-floor detection is effectual. A mass of experiments in lab and field are performed in order to analyze the profile characteristic. When the exploration depth and dipolar distance are changed, the form and polarity of the profile are different. The detection result is distinct when the dipolar distance is small. But its peak value is negative. The peak value will change to positive value when the dipolar distance is increased. But the distance can't be increase unbounded. The configuration parameters are chosen by experiment on the land. The exploration result in the sea floor are exact in this equipment

  • An observation of sea floor by a hovering type AUV HOBALIN with offshore multi-purpose work vessel Kaiyu at Middle Okinawa Trough

    A real sea survey result of sea floor at Middle Okinawa Trough by a hovering type AUV (Autonomous Underwater Vehicle) HOBALIN is reported. The depth of the survey target area is almost the intended limit of the AUV and it was the first time for the AUV to dive down to that depth since the AUV dived first time into the real sea almost one year ago. The operation of the survey with the AUV was done with a nongovernmental and non-academic commercial offshore multipurpose work vessel also as the first time. During the survey dive, the AUV succeeded to avoid chimneys with more than 10m height, which was done by the obstacle avoidance mechanism based on a line laser and USB camera with newly developed algorithm, and also succeeded many high-resolution photographs. By this survey cruise, we can conclude that the AUV is almost ready to be used heavily and effectively by general users.

  • Challenges toward the sea-floor massive sulfide mining with more advanced technologies

    It is remarkable that the mineral resource prices are soaring as well as the battle on the resource scramble in the world is heating up. The reasons are the world's active demand on the emerging economic power and the recent “resource nationalism” in resource-rich countries, etc. With these changes, the target of new development is expanding not only to the land deposits, but also to the sea-floor mineral resources. The technologies used for sea floor mineral resource exploration and the working tools in the deep-sea environment are progressing rapidly these days. However, the technology level is not yet practical enough. Unfortunately, the sea-floor mining has not been realized yet, although a few venture companies are planning to develop sea-floor mineral resources. Japan Oil, Gas and Metals National Corporation (JOGMEC) has started to accelerate the exploration program for the sea-floor massive sulfides (SMS) in the EEZ of Japan, and launched the investigation program for mining, processing and environment on SMS development. Through these programs, development of new technologies and introduction of more advanced technologies are progressing for the possible commercial mining after ten years. Along with these exploration and investigation, the 20 cm resolution bathymetry survey and sea-floor electromagnetic study has been completed in December 2010. The development of small-scale mining testing tools was also commenced. JOGMEC is also building a new marine resources research vessel aiming to go into service in 2012.

  • Sea-floor properties from the inversion of 3D multichannel seismic data: a submarine mud-volcanic flow in the Absheron block, offshore Azerbaijan

    We have developed a 3-term liquid/solid, strong contrast reflection equation and have used it, with an empirical V/sub P/ reflectivity relation, to invert the sea-floor seismic reflection to determine V/sub P/, V/sub S/, and density. Applying this technique to pre-stack data from a Caspian Sea 3D multichannel survey, we find that a submarine flow from the Absheron mud volcano, offshore Azerbaijan, has much higher seismic velocity and density than surrounding sea floor. We propose that this flow is enriched in high-density clasts of country rock - xenoliths - raised from depths of as much as /spl sim/9 km by the mud volcano. In contrast, onshore subaerial flows are predominantly low-density frothy gray clay. The 3D seismic data and gravity data further suggest that high-density, high-velocity regions near the mud volcano and buried up to 1000 m below the sea floor are stacked Pleistocene sea-floor mud-volcanic flows. These bodies appear to buttress slumping fault blocks.

  • The Research and Experiments of Sea-floor Transient Electromagnetic Method on the Sea

  • 3-D motion and depth estimation from sea-floor images for mosaic-based station-keeping and navigation of ROVs/AUVs and high-resolution sea-floor mapping

    A vision system has been developed in order to support the autonomous operation or operated-assisted missions of AUV and ROV near the ocean bottom. The sea-floor images, acquired by a down-look camera installed on the vehicle, are processed by the vision system in order to detect and estimate its motion in real time. This information is utilized to realize a number of capabilities, including automatic station keeping, navigation and trajectory following, and the construction of a composite (mosaic) image of the sea floor. We describe the system and provide sample results from various experiments for evaluating performance. We also provide examples from ongoing work, planned for implementation on the real-time vision system.

  • Two-dimensional Coplanar Magnetic Dipole-Dipole Sea-Floor Electromagnetic Data Explain and Response Analysis

    To apply the controlled source time-domain electromagnetic method in the sea- floor exploration. The coplanar magnetic dipole-dipole (HZHZ) configuration is adopted in this paper. The sea-floor transient electromagnetic fields are analyzed based on the model of the seafloor and seawater double half spaces. The expressions of the transient magnetic field and electric field under the step function are calculated. The second time induced electromotive force curves are simulated based on the theory analysis. In order to distinguish the response curse form on the land and in the seafloor, the seawater effect is discussed.

  • Design and Implementation of Communication Protocol of Sea-Floor Observatory
