UAV-based seagrass wrack orthophotos classification for estimating blue carbon

Research Overview When seagrass such as eelgrass flows out of seaweed beds, some of it is washed up and deposited on nearby beaches. This is called seagrass wrack. If it is utilized as a resource or managed well, it can be expected to contribute to blue carbon (carbon sequestered and stored by the marine ecosystem). Monitoring the annual occurrence of seagrass rack is the first step toward such management. In this study, we investigated a method to automatically classify seagrass rack from orthorectified images taken by an unmanned aerial vehicle (drone) along the Futtsu Coast of Tokyo Bay. By using a low-pass filter for preprocessing and ISODATA as the classification […]

Visiting Akanehama Seaside Park and Beach in Tokyo Bay in April 2023

A tour of Akanehama Seaside Park was held on Sunday, April 16, 2023. Under the spring weather, the tour was conducted as an activity of the Habitat Creation Project Team (PT) under the Public-Private Cooperation Forum for Tokyo-Bay Restoration under the guidance of the Narashino Marine Conservation Organization. In the morning, Dr. Sasaki participated in a meeting at 9:00 a.m. at the New Narashino Community Center in Narashino City, where he introduced the project "Improvement of Sediment Quality of Spawning Ground for Marbled flounder," a policy proposal of the PT. This project is not well known locally, even though it has been implemented in the sea area before Akanehama. Dr. […]
