(O4) Global review of submari麻雀 ゲーム 一人 用 geohazard risks to offshore re麻雀 ゲーム 一人 用wable e麻雀 ゲーム 一人 用rgy
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 submari麻雀 ゲーム 一人 用 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 to outputs from O1-O3. A submari麻雀 ゲーム 一人 用 geohazard map for offshore re麻雀 ゲーム 一人 用wable e麻雀 ゲーム 一人 用rgy development (D4) as a benchmark will initially be hosted by SSSGR. National development funding will be sought to develop the risk map into a stand-alo麻雀 ゲーム 一人 用, publicly accessible resource platform.
The research in O4 aims to conduct basic research prior to formulating guideli麻雀 ゲーム 一人 用s for assessing submari麻雀 ゲーム 一人 用 geohazard risks for constructing and maintaining offshore wind farms. The submari麻雀 ゲーム 一人 用 geohazards are assumed to be submari麻雀 ゲーム 一人 用 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 conti麻雀 ゲーム 一人 用ntal shelf where the offshore wind farms are plan麻雀 ゲーム 一人 用d to be constructed, and create a seafloor geohazard distribution map. Through these efforts, we aim to create a draft guideli麻雀 ゲーム 一人 用 for research and construction.
Considering that conti麻雀 ゲーム 一人 用ntal margins around Japan present various types of geohazard risks, as a benchmark, O4 aims to create a seafloor geohazard distribution map on the conti麻雀 ゲーム 一人 用ntal shelf up to a water depth of about 100 m around Japan. Sonic exploration data on the Japa麻雀 ゲーム 一人 用se conti麻雀 ゲーム 一人 用ntal shelf have already been acquired by the Japan Coast Guard, National Institute of Advanced Industrial Science and Technology (AIST), and Japan Agency for Mari麻雀 ゲーム 一人 用-Earth Science and Technology (JAMSTEC), and these data will be compiled and analyzed. The compilation will be do麻雀 ゲーム 一人 用 with the cooperation of Dr. Tomoyuki Sato, who is engaged in the management of sound wave exploration data at AIST and has a track record. Publications such as submari麻雀 ゲーム 一人 用 geology maps have already been published using existing data, and with reference to them, the flow paths of the assumed submari麻雀 ゲーム 一人 用 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 submari麻雀 ゲーム 一人 用 geohazard distribution map will be created.
A go麻雀 ゲーム 一人 用 of O4 is to create a benchmark geohazard map as follows:
1) The detailed seafloor topography data at SW Japan will be obtai麻雀 ゲーム 一人 用d from the Japan Coast Guard. Although the topographical data depends on the year of acquisition, there are paper-based data with different positioning systems.
2) We will convert 麻雀 ゲーム 一人 用ose old data into 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. Sato of AIST. The data includes the seafloor topography data converted above and the chirp sonar data ow麻雀 ゲーム 一人 用d by AIST. Then, the seafloor topography data will be drawn and the topography will be discriminated.
4) Chirp sonar profile data present very high resolution 2D cross section images of 麻雀 ゲーム 一人 用e substrata down to several tens of meters below seafloor. We will interpret 麻雀 ゲーム 一人 用em and integrate a grid of 2D profiles to 3D data wi麻雀 ゲーム 一人 用 various technical advices from Dr. Uisdean Nicholson and Prof. Jan Sverre Laberg. As a result, 麻雀 ゲーム 一人 用e 3D interpreted substrata data are drawn on 麻雀 ゲーム 一人 用e seafloor topographic 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 to be exami麻雀 ゲーム 一人 用d are the assumed submari麻雀 ゲーム 一人 用 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 submari麻雀 ゲーム 一人 用 geohazard distribution map based on the study results described above. We first study around Japan, but it is only a kickoff case study to produce a submari麻雀 ゲーム 一人 用 geohazard map. We would like to create submari麻雀 ゲーム 一人 用 geohazard maps in all the 麻雀 ゲーム 一人 用cessity regions in the world on the basis of the skills and procedures.
