    • Research Activities

    Marine environmental issues around the world are becoming more apparent as global environmental issues such as global warming, ocean acidification and deoxygenation become more complex and intertwined with local environmental issues such as the inflow of materials from land to coastal areas, and globalization is making it even more difficult to solve these problems. In other words, it is possible that your actions could have an impact on people living on the other side of the world, and vice versa. In this situation, the measures to be taken for each environmental issue will naturally differ. In our laboratory, we are considering what measures (mitigation and adaptation measures) are needed to solve environmental problems of different spatial and temporal scales, based on the results of current assessments and future predictions, while making the most of individual expertise (so please become a specialist, not a generalist!) and using various methods such as ocean observations and numerical modeling.


    The following photos show the potential impact of global warming, ocean acidification and overfishing on marine life and human society if these trends continue, and are not intended to show that this is an absolute certainty. Our research aims to predict possible negative impacts as quickly and accurately as possible, and to take countermeasures.

    Messages to Students

    I am studying on the impacts of global warming, ocean acidification, and deoxygenation, all of which are thought to be caused by excessive emissions of anthropogenic CO2, on coastal ecosystems, and are working to develop countermeasures (mitigation and adaptation measures) through the understanding of the current situation and future predictions. I am also conducting researches to clarify the local impacts of extreme events such as storms and marine heat waves, which are expected to increase in frequency and intensity as climate change progresses, on coastal ecosystems. I believe that the qualities necessary for interdisciplinary research are “physical strength, curiosity, imagination, and common sense,” and try to cultivate these qualities by going out of the lab as much as possible on weeknights and weekends. Easier said than done...


    If you are a student who is interested in entering graduate school and conducting research on the assessment, projection, and countermeasures for the impacts of climate change on marine ecosystems, fishery resources, and coastal communities, please feel free to contact me.
