Introduction
Twin submarine volcanoes, known informally as Volcano W, were discovered during a New Zealand-American submarine vent mapping expedition to the Kermadec arc in 2004. The two deep-water basaltic volcanoes lie SW of Curtis Island. The summits of both volcanoes are cut by small calderas, and evidence of diffuse hydrothermal venting was observed on the SE volcano in 2005. The SE volcano rises to within about 900 m of the sea surface and contains a cone in its summit caldera. The caldera walls expose pillow lavas, pillow tubes, localized sheet flows, and pillow breccias, with higher proportions of volcaniclastic breccias in the upper portion.---
