An immense shield volcano within the Shatsky Rise oceanic plateau, northwest Pacific Ocean (2013)
Journal Article
Sager, W. W., Zhang, J., Korenaga, J., Sano, T., Koppers, A. A. P., Widdowson, M., & Mahoney, J. J. (2013). An immense shield volcano within the Shatsky Rise oceanic plateau, northwest Pacific Ocean. Nature Geoscience, 6(11), 976-981. https://doi.org/10.1038/ngeo1934

Most oceanic plateaux are massive basaltic volcanoes. However, the structure of these volcanoes, and how they erupt and evolve, is unclear, because they are remote and submerged beneath the oceans. Here we use multichannel seismic profiles and rock s... Read More about An immense shield volcano within the Shatsky Rise oceanic plateau, northwest Pacific Ocean.

Towards a sustainable economy? Socio-technical transitions in the green building sector (2013)
