Daisuke Inazu
Specializations ：
Marine geophysics, Coastal engineering
- My research experiences have been mainly based on numerical physical simulation of the ocean. Oceans sometimes pose threats as storm surges and tsunamis to coastal communities. Research focus will be primarily on understanding, forecast, and evaluation of such marine hazards, and then on effective utilization of coastal seas. Research findings will be hopefully useful in human society as well as progress in fundamental science.
- Hydrodynamical ocean modeling of tsunamis, tides, and storm surges

Specializations ：
Coastal Engineering / Shallow Water Waves / Coastal Morphology / Coastal Disaster Prevention
-
- Research and numerical simulation on waves and currents in shallow water regions
- Sediment movement in coastal areas and beach topography change
- Coastal disaster (especially tsunamis and storm surges) prevention and evaluation of mitigation methods
Originally I was studying waves in coastal areas, especially how they behave after breaking and make the beach topography changed over time. Recently, I am interested in coastal disasters such as the tsunamis and how to reduce the damages by them, and what kind of things should be considered as comprehensive measures including people's awareness and city planning.
Including these socio-scientific factors, the science is based on your own observations and studies.
I would be very happy if you find something new through these experiences.

Specializations ：
Marine geochemistry / Marine geology
-
- Interstitial water in marine sediment
- Radioactive iodine
- Methane
- Subduction fluid migration system
The ocean is the largest reservoir of materials on Earth. In particular, the dissolved components of interstitial water in marine sediments contain a variety of dissolved materials, and their distribution is heterogeneous depending on chemical species, ocean area, and depth. We aim to clarify the factors controlling the distribution of dissolved materials by integrating knowledge from earth science (geology) and chemistry (which is called geochemistry).

-
- Measures against browsing damage by herbivorous fish
- Construction of artificial fishing ground for bivalves
- Recovery of fishing ground function using structural and non-structural measures
- Improvement of fishing ground function considering the life history of fishery organisms
A lot of fishery resources in Japan almost have no sign of restoration of their resource though many recovery measures have carried out. Seaweed beds and tidal flat in coastal region are important for many kinds of fishery organism, however, currently these area are reduce and their functions decrease. We studies to clarify the environment suitable for marine organisms and to effectively develop their environment.

Development of chemical sensors, which can be used for a entire water column from the surface of the ocean to deep sea, to investigate chemical characteristics near hydrothermal deposits and to uncover the chemical material cycles. These sensors are mounted on the variety of ocean observing platforms including underwater robots. We utilize the ocean engineering technology to develop novel sensing technologies and to bring them under the sea to measure in-situ chemical processes.

I am promoting research on marine life and environment from the aspect of engineering. "We analyze our own measured data by yourself", we go to the field (ocean), analyze the data, and aim to find further problems. I am convinced that they have learned that they need approaches to problems, their ability to solve (design power) and importance of cooperation. Also, I am keeping in mind the research that I can feed back to the industry as much as possible, not doing research for research. For that reason, I am thinking about the wide field of view, the use of new devices for marine / fishery production, and system construction.
