	abstract = {Observations at the submarine volcano NW Rota-1, Mariana arc, have provided a unique opportunity to study basaltic explosive eruptions at {\~{}}~550~m below sea level. In particular, during one week of observations in 2006, the active vent evolved from a region of diffuse gas venting and slow lava effusion to a focused vent that emitted a nearly continuous stream of gas with entrained juvenile pyroclasts. The eruptions were small, strombolian bursts that ejected bomb-sized pyroclasts meters above the vent and produced buoyant plumes that rose tens of meters above the vent and contained variable amounts of ash. Sampled pyroclasts are dominantly coarse ash and lapilli with fluidal textures that provide evidence of magmatic fragmentation. However, the blocky morphologies of some clasts, combined with visual evidence of secondary fragmentation, suggest that quench granulation due to rapid cooling was also important in pyroclast formation. Rapid cooling is also suggested by the slow rise of buoyant plumes (which indicates a low heat content and small density contrast with surrounding seawater). Rapid plume deceleration in seawater limited deposition of coarse ash, lapilli, and bombs to within a few meters of the vent, and allowed recycling of <={\~{}}15{\%} of the ejected clasts. Petrologic evidence for pyroclast recycling is provided by numerous microcrystalline inclusions incorporated within microlite-poor matrix glass. The matrix glass within these inclusions is strongly enriched in chlorine (},

	abstract = {Northwest Rota-1 Seamount is the first place on Earth where a submarine volcanic eruption was witnessed in 2004, and, remarkably, it appears that the volcano has been erupting continuously ever since. NW Rota-1 is located {\~{}} 100 km north of Guam in the western Pacific, within the newly designated Mariana Trench Marine National Monument (http://www.fws.gov/marianastrenchmarinemonument). With a summit depth of 520 m, it is a symmetrical cone of basaltic andesite composition (Figure 1) formed in the subduction zone setting of the Mariana volcanic arc. It was identified as a site of particular interest in 2003 when sampling of its overlying hydrothermal plume showed very high magmatic volatile input (Resing et al., 2007). Consequently, it was one of several seamounts targeted for dives with a remotely operated vehicle the following year. During these dives, an actively erupting vent was discovered at a depth of 550 m; lava, fluid, and gas samples were collected; and colonies of shrimp, limpets, and crabs (some of them new species) were found living in the volcano summit{\textquoteright}s harsh conditions (Embley et al., 2006; Lim{\'e}n et al., 2006).},
