There are more habitats for marine organisms in ports than is commonly realized. Using a navigational echo sounder, we were able to get visual readouts of the underwater topography of canals in the Port of Tokyo area. We learned that waters of depths less than 3 meters, optimal for marine organism habitats, comprise 18% of the total area. Ports have great possibilities as areas for the growth of rich ecosystems as well as for introducing many people to the ocean's charms.

The bottleneck for research into hydrothermal vent organisms was that they couldn't be bred for study. In order to break through this limitation, methods for the collection and breeding of hydrothermal organisms was established. Through the raising of these organisms, I hope to clarify many aspects, from their reproduction to their ecology.

The large cargo ships that have depended on fossil fuels will not be able to avoid the energy-saving and zero emissions revolution. The industry-academic joint research project, the Wind Challenge Project, aims at making maximum use of wind energy through the realization of hybrid shipping vessels using large, hard, contractible sails, and began carrying out land-based experiments using reduced scale models from January 2014. This article introduces this research.
