Mata Ua

one of the 7 volcanoes in the North Mata volcanic complex; classified here as arc volcano, but at the 2018 AGU Fall Meeting this tectonic setting was distinguished as rear-arc and the region was distinguished as NE Lau Basin; Baker et al. (2010): "The 25-km-long chain of Mata volcanoes lies ... separated from both the arc front and the spreading ridge"; 2012 cruise blog, accessed 24 April 2015, http://oceanexplorer.noaa.gov/explorations/12fire/logs/summary/summary.html: "September 20 (Q-328) discovered an extensive hydrothermal field on the steep slope. Prolific long-necked barnacles and other vent animals colonized the slope and older sulfide chimneys and several black smokers were discovered and sampled in a depth range of 2397-2356 m. At least two of the smokers appeared to be boiling. The maximum temperature recorded was 360 C... the hottest site in the NE Lau to date."; video of black smoker chimneys, dive Q328, accessed 24 April 2015, http://oceanexplorer.noaa.gov/explorations/12fire/media/12firestream_playlist.html#; WHOI YouTube video accessed 24 April 2015, https://www.youtube.com/watch?v=O5WAWe9XgA4&list=PL1CGd4Scv4GJsaaFRzItk-btFI757bH8f&index=5; Baker et al. 2019: site 38 in Table 2;
