Hydrothermal edifices within the Endeavour vent system. (a) The Bastille structure, rising > 15 m above the seafloor, is typical of structures in the Main Endeavour, High Rise, and Salty Dawg hydrothermal fields, exhibiting numerous active flanges and black smoker orifices at its summit. Mixing of hydrothermal fluids and seawater in the porous outer walls supports dense communities of limpets, palm worms, scale worms, and tubeworms. This image shows one of the small pinnacles that forms the summit of Bastille. The scale bar in all images is ~ 1 m.

High-resolution (~ 5 m) bathymetry map of the Endeavour Integrated Study Site “bull’s-eye,”the Main Endeavour Field. The bathymetry was collected in 2005 as part of a joint project between the University of Washington, the W.M. Keck Foundation, and NEPTUNE Canada using the autonomous vehicle ABE. Venting in the southern cluster of chimneys, known as the Bastille complex, has been waning following the 1999–2000 intrusive event.

(a) The Endeavour Segment is located ~ 300 km off the coast of Vancouver Island and is a Canadian Marine Protected Area. It is bounded to the north by Middle Valley and West Valley, and to the south by the Cobb propagator. (b) The Main Endeavour Field was chosen as the Ridge 2000 Endeavour Integrated Study Site bull’s-eye because of its large and vigorously venting sulfide structures, because it was believed to be dominantly in a tectonic phase with significant seismic activity, and because it had a rich history of study by a diverse array of investigators.

Interdisciplinary lithosphere-to-hydrosphere representation of Endeavour Segment. This image shows the surface bathymetry underlain by multichannel seismic results from Carbotte et al. (2002) and Van Ark et al. (2007). For ease in viewing and graphical representation, the along-axis transect has been moved slightly to the east of the ridge axis; the white dashed line indicates the location of the along-axis survey line within the axial rift.

(A) The “Arches” area south of the Tubeworm Pillar location~one year after the 2005/2006 eruption(s), with diffuse vent flow, white staining, brachyuran crabs and Tevnia jerichonana tubeworm colonization at the base of eruptive lava remnants (2503 m depth). (B) Tevnia colonization following the 2005/6 eruption(s) in the TICA vent area with the outstretched Alvin manipulators imaging and collected in-situ fluid chemical data associated with this assemblage (2517 m depth).

Arenal volcano in Costa Rica has erupted nearly continuously since 1968. The volcanic edifice is often cited as providing our typical view of a volcano.

View of the volcanic mountains of northern Adka Island in the central Aleutians, looking to the northwest. There are three volcanoes in the picture. From right-to-left they are Korovin, Konia and Kliuchef. Kliuchef actually looks like two edifices due to glacial erosion. The Bering Sea is on the right. On the left, a USC graduate student collects volcanic rock samples. Picture courtesy of Gene Yogodzinski, University of South Carolina. Picture taken July, 2004.
