Project team introduction

Project member

  • Dr. Teruhisa KOMATSU

Dr. Teruhisa Komatsu, an expert advisor at Japan Fisheries Resource Conservation Association (formerly professor at Yokohama College of Commerce and associate professor of Atmosphere and Ocean Research Institute, the University of Tokyo), has devoted his career for studying coastal habitats including seagrass by using various techniques of remote sensing. He has been collaborating with NOWPAP CEARAC in mapping seagrass in the Northwest Pacific region. He has also been leading the Ocean Remote Sensing Program of IOC Sub-Commission for the Western Pacific (IOC/WESTPAC) to map coastal habitats of the south east Asia.
As a CEARAC expert for mapping seagrass, Dr. Komatsu helped NOWPAP CEARAC develop “A manual for seagrass and seaweed beds distribution mapping with satellite images” in 2015 and edit “Feasible Study for Assessment of Seagrass Distribution in the NOWPAP Region (2018)” in 2017. With his profound knowledge and experiences on remote sensing techniques applied in the study on coastal habitats, Dr. Komatsu leads this project.

Algorithm development and design
  • Dr. Tatsuyuki SAGAWA

Dr. Tatsuyuki Sagawa is a senior researcher of Remote Sensing Technology Center of Japan (RESTEC) and a specialist in mapping of shallow water seafloor beds with remote sensing techniques. He has developed the Bottom Reflectance Index (BRI) algorithm to remove the effect of water column influences from an optical satellite image for accurate sea floor mapping. In this project, Dr. Sagawa has also developed the grand design of the seagrass mapping tool using Google Earth Engine.

Project Coordinator
  • Dr. Genki TERAUCHI

Dr. Genki Terauchi is a senior researcher at NOWPAP CEARAC. He joined NOWPAP CEARAC in 2004 and has been leading CEARAC activities related to ocean remote sensing. He has assessed damage of seagrass in Shizugawa-Bay caused by the huge tsunami of the Great East Japan Earthquake on 2011 March 11 and helped local community restore seagrass by mapping seagrass distribution before the tsunami.  He is responsible for management of the Mapseagrass project.
