Bio-logging Science, the University of Tokyo

UTBLS began in 2007 as a project of University of Tokyo to assess and explain unknown ecology of life in the oceans. The members of UTBLS have visited islands, offshore waters and coastal areas to attach data-loggers to more than 50 species including cetaceans, pinnipeds, sea turtles, sea birds and fishes in the world. Data-loggers can provide animal’s world we had never seen before.

We welcome collaboration with graduate students, postdoctoral fellows and scientists. Please contact us if you are interested in Bio-logging Science.
