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!
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.
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!
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.
The following paper, published in Journal of JSCE B2 (Coastal Engineering), received Coastal Engineering Paper Award from the JSCE Coastal Engineering Committee. This research focused on a blue carbon function of Tokyo Bay, one of the world's representative urban bays. This paper reported on the continuous observation of partial pressure of carbon dioxide (pCO2) in the surface seawater in a harbor using an inexpensive and practical handmade sensor system. Congratulations to Masanori Endo, Project Academic Specialist, and SUN Jing, 2nd-year master's student. Publication Endo, M., Sun, Jing and Sasaki, J.: Continuous observation of partial pressure of carbon dioxide in winter at a port in the head of Tokyo Bay. Journal […]
We conducted a one-month field survey in the Fukido River mangrove forest in Ishigaki Island again in the summer of 2022; Nakamura (D2) and Phyo (M2) were major contributors. We again received supports from the Port and Airport Research Institute, the National Institute for Environmental Studies, and Osaka Metropolitan University. This summer, we mainly investigated the process of inorganic carbon export from mangrove soils and the carbon cycle between mangroves, seagrasses, and coral reefs. We express our gratitude to the members of Fukui Prefectural University for their assistance in collecting and analyzing groundwater samples. We will continue our research to understand the whole picture of blue carbon in mangroves in […]
Wataru Nakamura, a second-year PhD student, received the Outstanding Student Presentation Award in the Atmospheric and Hydrospheric Sciences Section at the 2022 Congress of the Japan Geoscience Union (JpGU Meeting 2022). More than 550 students entered the competition; about 5-10 % of the entries in each section received this award in the 2022 Congress. The title of the presentation was "Tidal-driven high CO2 evasion from mangrove swamp to the air and adjoining waters over spring-neap tidal cycles in the estuary of Fukido River, Ishigaki Island". Congratulations!
With the cooperation of the Port and Airport Research Institute, Nakamura (D1) and Phyo (M2) have started to study carbon dioxide sequestration and emission by mangrove forests. In August 2021, they conducted a one-month field survey in the mangroves of the Fukidori River in Ishigaki Island. Fukido River mangrove in Ishigaki Island Mangrove forests are said to have a high carbon sequestration capacity due to carbon sequestration by photosynthesis and the deposition of organic matter by complex above-ground roots. The carbon sequestration is also promoted by the fact that the soil is always in a reducing state due to the high organic matter content, and the rate of soil decomposition […]
