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 […]
Presentation Award in the Atmospheric and Hydrospheric Sciences Section at the 2023 Congress of the Japan Geoscience Union
Wataru Nakamura, Ph.D. candidate (3rd-year), received the Outstanding Student Presentation Award in the Atmospheric and Hydrospheric Sciences Section at the 2023 Congress of the Japan Geoscience Union (JpGU Meeting 2023). The title of the presentation was "Inorganic carbon cycle in mangrove soils and possibility for assimilation of outwelled mangrove carbon in seagrass and coral ecosystems." In the presentation, the carbon cycle among mangroves, seagrasses, and coral reef ecosystems was discussed using radiocarbon isotopes as a tracer. Congratulations!
ICOPMAS-2022
Dr. Sasaki attended the 14th International Conference on Coast, Port and Maritime Structure (ICOPMAS-2022), which was the first face-to-face international conference for him since COVID-19. Dr. Sasaki deeply appreciates PMO and Prof Soltanpour. Itinerary It was a business trip for one night and four days with the following itinerary of Qatar Airways flights with a connection in Doha. Dr. Sasaki was told that he only needed to obtain an arrival visa for this business trip, which the secretary of the conference should have arranged, so he went straight to immigration at Imam Khomeini International Airport; however, the immigration officer told him that his visa was not registered. He went to […]
Installing Intel oneAPI (ifort) on Ubuntu 22.04 LTS
This is translation of this article by ChatGPT. I installed Intel oneAPI Base Toolkit and HPC Toolkit (ifort) on Ubuntu 22.04 LTS of WSL2 of Windows 11 Pro for the purpose of numerical computation using Intel C compiler and Intel Fortran compiler. I referred to this. Intel compiler can be used free of charge. Also, it is very convenient because you can install it with apt. Installation of Intel oneAPI The official guide is here.

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. […]
Seminar by a visiting Ph.D. candidate from the UK in April 2023
Ph.D. candidate from Manchester Metropolitan University, UK, visited our laboratory and gave a seminar on April 10, 2023. The lecture's title was "Using Fractals to approximate riverbeds for realistic flow analysis." It would be a valuable technique for creating high-resolution spatiotemporal data. After the seminar, we held a reception party to deepen our friendship.
Lab's farewell party in March 2023
The commencement for the graduate school was held on March 23rd and the graduation ceremony for the undergraduate school was held on March 24th. One master’s student and one undergraduate student from our laboratory were awarded degrees. Congratulations! Lab's farewell party
Best Poster Award at the 70th annual meeting of the Ecological Society of Japan (ESJ70)
Wataru NAKAMURA, a Ph.D. candidate and Phyo Thet Naing, a former master student, received the Best Poster Award in the Material Cycling Section at the 70th Annual Meeting of the Ecological Society of Japan (ESJ70). The title of the poster is Carbon and nutrient cycling among mangrove-seagrass-coral continuum in the Fukido estuary, Ishigaki Island, Japan." Congratulations!
Seminar by Reader from University of East London in February 2023
We invited Ravindra Jayaratne, a reader (equivalent to associate professor) at University of East London, to the University of Tokyo for one week in late February 2023. On February 27, we asked him to give a lecture at our laboratory seminar.
Lab's Kagura skiing and snowboarding trip in February 2023
We enjoyed skiing and snowboarding at Kagura Ski Resort (Niigata Prefecture) for one night and two days from February 12th to 13th, 2023. The nearest station is Echigo-Yuzawa Station on the Joetsu Shinkansen line. There is also a hot spring facility. We stayed at Kagura House. We were going skiing and snowboarding from here. We took the Mitsumata Ropeway from Mitsumata Station, which is right near the guest house, to Mitsumata Area. Mitsumata Ropeway Kagura main slope Kagura House
