The lab predicts marine environments and ecosystems in pursuit of sustainable ocean use.
AboutAbout the lab
Toward a better future through sustainable ocean use
The Ocean Environment Systems Lab conducts research on using the ocean sustainably.
The lab carries out environmental impact assessments of ocean-use technologies for resources, energy, and food production.
Its research also covers technologies and policies for conserving, restoring, and making use of marine and coastal ecosystems.
The lab models ocean currents, ecosystems, and socioeconomic systems, and uses computers to predict future changes.
Key terms
- Environmental impact assessment
- Investigating and estimating how a development or project will affect the natural environment and living organisms
- Seaweed and seagrass beds
- Coastal areas thickly covered with seagrass and seaweed. They help purify the water and support habitats for fish and other animals as well as fishery resources
- Deep ocean water
- Seawater from the deep layers of the ocean. It is rich in nutrients and stays stable at low temperatures
- Storm surge
- A phenomenon in which the sea level rises sharply because of a typhoon or similar storm, causing seawater to surge onto land
ResearchResearch themes
To support sustainable ocean use, the lab predicts and evaluates impacts on the environment, including ecosystems. Combining on-site observation and surveys with numerical simulation, it works on the conservation, remediation, and restoration of coastal environments and ecosystems.
*Illustrative imageA simulator for coastal fisheries
The lab develops a simulator that models fishing-ground environments and ecosystems as well as fishing operations, distribution, and sales, reproducing and predicting the flow of the fishing industry from production to consumption. Its purpose is to support the design of policies to improve fisheries.
*Illustrative imageCreating seaweed beds with deep ocean water
This research grows seaweed beds by pumping nutrient-rich deep ocean water into the sunlit layer of the sea. Using both simulation and experiments in the actual sea, the lab investigates discharge and retention methods and their effects on the surrounding waters.
*Illustrative imagePredicting the future of shellfish habitats
The lab uses simulation to predict how construction work will change shellfish habitats. It also collects data through field surveys, and the prediction results are used in building consensus with local residents.
*Illustrative imagePredicting storm surge damage
To prepare for the combined damage from strong typhoon winds and storm surges, the lab conducts probabilistic storm surge simulations. It aims to contribute to safe and secure living for people.
