Ontong Java Plateau News Today

While it's the reigning theory now, the road to acceptance was long and bumpy for plate tectonics, which describes how large portions of Earth's crust slide, grind, rise and sink ever so slowly across its sludgy mantle.

Discover the secrets of the dinosaur-era superstructure in the Pacific Ocean that is still forming. Learn about the Melanesian Border Plateau, its volcanic rocks enriched in rare elements, and its complex topography shaped by tectonic plates and climate changes. Explore the origin and evolution of superstructures and their impact on the environment and biodiversity of the ocean.

Zealandia was separated from the supercontinent Gondwana around 85 million years ago. Its unique geological features have made it an area of interest for scientists studying Earths history and the dynamics of crustal plates. 

The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, suggests new research led by Oregon State University.

Loren Kroenke, emeritus faculty researcher in the UH Mānoa School of Ocean and Earth Science and Technology, died on May 17 at the age of 84.
