Fig. 3From: Discovery of a conical feature in Halmahera waters, Indonesia: traces of a late-stage hydrothermal activityThe conical feature: Yudo Sagoro Hill. a Multibeam bathymetry overlaid with magnetic profiles/wiggles. Black wiggles: surveyed magnetic profile in each survey line. White wiggles: surveyed magnetic profile in the middle of the feature, used in the 2.5-D magnetic modelling in Fig. 6. White arrow: survey direction of the centre line. b Multibeam bathymetry with interpreted faults. c Bathymetric slope. d Gridded magnetic anomaly. e RTE of the magnetic anomaly. f Analytic signal of the RTE magnetic anomalyBack to article page
