The lab makes changing marine ecosystems visible using a variety of methods.
AboutAbout the lab
Going into the field to understand the sea.
The Ecosystem Change Analysis Lab conducts research that makes changing marine ecosystems visible using a variety of methods.
Using biologging, biotelemetry, and acoustic measurement instruments, it develops methods for monitoring marine biological resources.
It is an independent research field without its own facilities, and effectively uses a satellite office of the Hakodate City International Fisheries and Marine Research Center as its research base.
It has field sites across Japan and sometimes overseas, and conducts joint research with a variety of organizations.
Key terms
- Biologging
- A method of attaching small recorders (loggers) to animals to collect data on their behavior and surrounding environment
- Biotelemetry
- A method of attaching transmitters to animals and receiving their signals from a distance to study their location and movements
- Acoustic measurement
- A method of emitting sound underwater and using the echoes that return to measure the distribution of fish schools and other organisms
ResearchResearch themes
The lab visualizes changing marine ecosystems, from plankton to whales, using a variety of methods. It aims to use the latest measurement techniques to help solve problems concerning marine ecosystems.
*Illustrative imageBehavioral Experiments and Measurements in Large Tanks
Using the large tanks and analysis rooms of the Hakodate City International Fisheries and Marine Research Center, the lab conducts behavioral experiments on marine organisms, measurements with survey instruments, and dissections of marine mammals.
*Illustrative imageFrom Plankton to Whales
The lab conducts surveys and research to dynamically visualize marine ecosystems, from plankton to whales. A distinctive feature is the large amount of fieldwork, both in Japan and abroad.
*Illustrative imageSeeing Underwater with Sound and Diving
Using methods such as acoustic measurement and diving observation, the lab monitors and visualizes aquatic ecosystems. Its study sites vary widely, including lakes, ponds, rivers, and the sea.
