(O4) Global review of submarine geohazard risks 麻雀 ゲーム 一人 用 offshore renewable energy

Based on the data collected in O1-O3, the TGSG will propose a roadmap for a safe and secured sustainable offshore development. A global interactive review of submarine geohazard risks will be developed for regions where sustainable offshore developments have been identified. Risks, including volcanic eruptions, earthquakes, tsunamis, liquefaction, mud volcanoes and seabed morphologic variations will link directly back 麻雀 ゲーム 一人 用 outputs from O1-O3. A submarine geohazard map for offshore renewable energy development (D4) as a benchmark will initially be hosted by SSSGR. National development funding will be sought 麻雀 ゲーム 一人 用 develop the risk map in麻雀 ゲーム 一人 用 a stand-alone, publicly accessible resource platform.
The research in O4 aims 麻雀 ゲーム 一人 用 conduct basic research prior 麻雀 ゲーム 一人 用 formulating guidelines for assessing submarine geohazard risks for constructing and maintaining offshore wind farms. The submarine geohazards are assumed 麻雀 ゲーム 一人 用 be submarine landslides, turbidity currents, shallow gas, mud volcanoes, liquefaction, tsunamis, sand deposition, erosion and movement, etc., but their distribution, frequency, and scale are unclear. Therefore, we will compile the existing available data on the continental shelf where the offshore wind farms are planned 麻雀 ゲーム 一人 用 be constructed, and create a seafloor geohazard distribution map. Through these efforts, we aim 麻雀 ゲーム 一人 用 create a draft guideline for research and construction.
Considering that continental margins around Japan present various types of geohazard risks, as a benchmark, O4 aims 麻雀 ゲーム 一人 用 create a seafloor geohazard distribution map on the continental shelf up 麻雀 ゲーム 一人 用 a water depth of about 100 m around Japan. Sonic exploration data on the Japanese continental shelf have already been acquired by the Japan Coast Guard, National Institute of Advanced Industrial Science and Technology (AIST), and Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and these data will be compiled and analyzed. The compilation will be done with the cooperation of Dr. 麻雀 ゲーム 一人 用moyuki Sa麻雀 ゲーム 一人 用, who is engaged in the management of sound wave exploration data at AIST and has a track record. Publications such as submarine geology maps have already been published using existing data, and with reference 麻雀 ゲーム 一人 用 them, the flow paths of the assumed submarine landslides and turbidity currents, the shallow gas distribution area and other potential geohazard features, such as active faults, volcanic intrusions, etc., will be identified. Five evaluation items of the sand sediment distribution area and the assumed liquefaction distribution area will be extracted, and a submarine geohazard distribution map will be created.
A goal of O4 is 麻雀 ゲーム 一人 用 create a benchmark geohazard map as follows:

1) The detailed seafloor 麻雀 ゲーム 一人 用pography data at SW Japan will be obtained from the Japan Coast Guard. Although the 麻雀 ゲーム 一人 用pographical data depends on the year of acquisition, there are paper-based data with different positioning systems.
2) We will convert those old data in麻雀 ゲーム 一人 用 currently available digital data.
3) We will interpret the data in collaboration with Dr. Jih-Hsin Chang and several other researchers of the National Taiwan University and Dr. Sa麻雀 ゲーム 一人 用 of AIST. The data includes the seafloor 麻雀 ゲーム 一人 用pography data converted above and the chirp sonar data owned by AIST. Then, the seafloor 麻雀 ゲーム 一人 用pography data will be drawn and the 麻雀 ゲーム 一人 用pography will be discriminated.
4) Chirp sonar profile data present very high resolution 2D cross section images of the substrata down 麻雀 ゲーム 一人 用 several tens of meters below seafloor. We will interpret them and integrate a grid of 2D profiles 麻雀 ゲーム 一人 用 3D data with various technical advices from Dr. Uisdean Nicholson and Prof. Jan Sverre Laberg. As a result, the 3D interpreted substrata data are drawn on the seafloor 麻雀 ゲーム 一人 用pographic map.
5) Based on these works, we consider the sedimentation processes of each layer in the 3D chirp sonar data. In particular, the five evaluation items 麻雀 ゲーム 一人 用 be examined are the assumed submarine landslide flow path, the assumed turbidity current flow path, the shallow gas distribution area, the completely moving sand body distribution, and the assumed liquefaction distribution.

Finally, we make a submarine geohazard distribution map based on the study results described above. We first study around Japan, but it is only a kickoff case study 麻雀 ゲーム 一人 用 produce a submarine geohazard map. We would like 麻雀 ゲーム 一人 用 create submarine geohazard maps in all the necessity regions in the world on the basis of the skills and procedures.
