Research

An overview of research activity at IPRC is provided by our Science Plan.

Our research results are reported in many ways. Our Annual Reports and our semiannual newsletter IPRC Climate include research highlights. A full listing of our refereed scientific publications is found at Scientific Publications. Projects in which IPRC participates through the APDRC are described at APDRC Projects.

Animations of interviews and research findings on such topics as global warming, ocean acidification, past climate are found on the IPRC YouTube Channel.

Every quarter, the IPRC features scientific highlights particularly relevant to its principal funding agencies - the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), NASA, and NOAA. These are reported as PowerPoint slides.
