Ocean is the source of life and has given rise to biodiversity. To understand our planet and human beings, knowledge about marine organisms are essential. The 21st century is the era of life and environmental sciences. Shimoda Marine Research Center (SMRC), the center for the research and education of marine biology in University of Tsukuba, aims to explore the basic principles of life and interactions among organisms through education and research using both basic and advanced technologies on marine organisms.

imageProf. Jason Hall-Spencer and Assistant Prof. Ben Harvey at the Shimoda Marine Research Center, University of Tsukuba, revealed that ocean acidification could have broad reaching effects on ecosystems and the services they provide. Their new study provides a synthesis of the likely effects of ocean acidification on ecosystem properties, functions and services and is based on laboratory experiments and observations along natural gradients in CO2.
