The lab empirically investigates magma and fluids in subduction zones.

The Volcanology and Geofluids Lab studies the movement of magma and subsurface fluids in active subduction zones such as the Northeast Japan arc. The lab investigates the mechanisms by which magma is generated, rises, resides underground, changes in composition, and leads to eruption, as well as the relationship between plate dehydration and earthquake occurrence. It uses a variety of methods, including fieldwork, chemical analysis of rocks and minerals, high-pressure, high-temperature experiments, and numerical simulation.

The lab investigates plate motion and the dynamism of the Earth through rocks from the ocean floor.

The Ocean Floor Science Lab studies the motion of the ocean floor and of plates as recorded in rocks, and the dynamism of the Earth as reflected in magma. The lab aims to clarify the structure and evolutionary history of subducting oceanic plates from the chemical and isotopic compositions recorded in basalts from submarine volcanoes. The lab also studies rocks of the Pacific Plate that is subducting into the trench, and rocks of ancient deep ocean floor exposed in eastern Hokkaido. The lab is the Ocean Floor Science Division of the Faculty of Science and Graduate School of Science at Tohoku University, and is also the Geochemistry Research Field of the Center for Northeast Asian Studies.

The lab studies seaweed beds through the interactions between seaweeds and herbivores.

The Aquatic Plant Ecology Lab studies seaweed beds, the seaweed communities that form on coastal rocky reefs, from the perspective of the interactions between seaweeds and herbivores. Marine forests formed by large brown algae such as kelps and Sargassum species are also places where fish and shellfish live and spawn, and where their larvae and juveniles grow. Centered on field surveys using SCUBA diving, the lab also carries out rearing and culture experiments in the laboratory and genetic analysis. Working with people in the fishing industry and researchers at food companies, the lab has also carried out research aimed at improving wakame farming techniques and raising the quality of sea urchins.

A lab that explores the ocean's material cycles through plankton.

The Biological Oceanography Lab studies plankton living in the sea, with the aim of clarifying material cycles in the ocean mediated by living organisms. The lab investigates plankton from two perspectives: the fisheries science perspective of sustaining the use of marine biological resources over the long term, and the oceanography perspective of plankton as the driving force that carries carbon fixed at the surface down to the deep sea. Professor Yamaguchi is in charge of zooplankton and the open ocean, and Associate Professor Nishitani is in charge of phytoplankton and coastal areas. The lab covers both zooplankton and phytoplankton, from coastal areas to the deep sea of the open ocean.

A lab that explores how genes and proteins work in Aspergillus oryzae and yeast.

The Eukaryotic Microbial Functions Lab studies molds (especially Aspergillus oryzae) and yeast, which play important roles in the fermentation industry, focusing on how the genes and proteins involved in producing useful substances function. Based on genetic resources and genome information, the lab systematically clarifies gene expression regulation and protein functions, and aims to improve productivity by understanding and modifying cell functions. The lab also explores the functions of unknown and unused genes, and conducts research on developing technologies to solve environmental problems and on industrial applications.
