Near-seafloor magnetic mapping of off-axis lava flows near the Kairei and Yokoniwa hydrothermal vent fields in the Central Indian Ridge [PDF]

, 2018
The Kairei (KHF) and Yokoniwa hydrothermal fields (YHF) are hosted in mafic as well as ultramafic rocks distributed at an off-axis volcanic knoll of the Central Indian Ridge.

Signatures of widespread Surtseyan volcanism at the northern Reykjanes ridge

Communications Earth & Environment
Submarine explosive volcanism shapes seafloor morphology, impacts marine ecosystems, and poses risks to maritime infrastructure and coastal communities. However, its occurrences and drivers remain poorly constrained, especially for basaltic systems. Here

Bathy-morphological setting of the Submarine Pausanias Volcanic Field, South Aegean Active Volcanic Arc [PDF]

Journal of Maps, 2018
High-resolution swath-bathymetry has been acquired during recent surveys in Saronikos Gulf, near the densely populated city of Athens. This paper presents the first detailed bathymetric map, at a scale of 1:12,000, of the active Submarine Pausanias Volcanic Field located offshore NW Methana Peninsula in Saronikos Gulf, Aegean Sea (Main Map).
