  • Discovery of genes that prevent animals to migrate from the ocean onto the freshwater and the land
  • Nishino-Shima Island now – Challenge to monitor the volcanic eruptions of the isolated island in the sea
  • Nishino-Shima Island Investigation by a low-cost AUV “HATTORI”
  • Comprehensive EEZ management Offshore base networking -Review of “Grand Design for the OCEAN in the 21st Century” by Nippon Keidanren (Japan Business Federation) in 2000
  • AUV SPICE-1 challenge to the North Sea!
  • Expanding the possibilities of underwater monitoring with the “Amphibious drone”
  • Top predator in the deep sea – Discovery of a new species, a giant deep-sea fish “Narcetes shonan”

More than 260 people participated in the forum and enjoyed the discussions.  The next forum will be held on April 22nd 2022.  We hope that a larger audience can attend the next forum face-to-face.

The Singapore chapter has been active in organizing technical talks and various administrative meetings. Due to COVID-19 related restrictions, all meetings were held in a virtual setting with no in-person social events in 2021. In the middle of this year, we organized a talk by Prof Milica Stojanovic from the Northeastern University. It was organized as part of the on-going distinguished lecture series. The talk was titled “Multicarrier Acoustic Communication in Doppler-limited Regimes” and was presented as a virtual session on May 25th, 2021. The lecture was aimed at learning custom made Doppler compensation methods and their application to multi-carrier systems with an aim to improve performance under extreme Doppler distortion scenarios.
