Akkeshi Marine Station

Masahiro NAKAOKA, Ph.D. Professor/Director

Research field	Marine Ecology, Community Ecology, Biodiversity Ecology
Research Subjects	1. Biodiversity and ecological function in seagrass beds and their relativeness 2. Long-term and broad-scale changes of biodiversity in seagrass and kelp beds 3. Investigation on the effects of local and global environmental changes on coastal ecosystems
To students	Let’s study with us about marine ecosystem and ecology in eastern Hokkaido region which has the richest nature in Japan.

Tomonori ISADA, Ph.D. Associate Professor

Research field	Biological Oceanography, Marine Biogeochemistry, Satellite Oceanography
Research Subjects	1. Seasonal variability in phytoplankton assemblages and photosynthetic features in Coastal Oyashio region 2. Satellite remote sensing of spatio-temporal changes in phytoplankton functional types and primary productivity in Oyashio region 3. Phytoplankton dynamics in biogeochemical cycle of the coastal marine ecosystem
To students	We hope that the course will provide you a fruitful opportunity for ocean and marine coastal ecosystem. It will be our pleasure to start the course with all of you.

Ippei SUZUKI, Ph.D. Specially Appointed Assistant Professor

Research field	Marine Ecology, Ethology, Diving Physiology
Research Subjects	1. Development of methods to quantify energy budgets of marine apex predators 2. Respirometry and biologging to quantify energy expenditure of marine mammals 3. Animal-borne blood sampler to understand mechanisms of dive responses in pinnipeds
To students	The east coast of Hokkaido has a unique nature mixed with both cold-current ocean and fresh-water ecosystems. Our courses will provide you experiences to study how to understand these environments.

Muroran Marine Station

Chikako NAGASATO, Ph.D. Professor/Director

Research field	Phycology, Morphology, Cell Biology
Research Subjects	1. Formation of cytokinetic plane in brown algae 2. Structures and functions of brown algal plasmodesmata
To students	I hope you find uniqueness and significance of algae in marine environments during your stay in our station.

Kensuke ICHIHARA, Ph.D. Assistant Professor

Research field	Phycology, Molecular Biology, Taxonomy
Research Subjects	1. Evolution of reproductive systems and sex-determining mechanisms in green seaweed 2. Environmental adaptation of green seaweed
To students	Our programs will let you notice the biodiversity of seaweeds.

Yusuke HORINOUCHI, Ph.D. Specially Appointed Assistant Professor

Research field	Cell Biology, Developmental Biology, Evolutionary Ecology
Research Subjects	1. Diversification of reproductive cell development and life cycles in green seaweed 2. Diversification of sexual reproductive cells in green seaweeds 3. Seaweed propagules-ciliates interaction in coastal food webs
To students	In our courses, you will study seaweeds from a wide perspective, ranging from field surveys to microscopic observations. You may find how fascinating seaweeds are.
