Notes on Vent Field Description: 
eruption observed with ROV Jason II in 2009; Resing et al. (2011): "At the summit, hydrothermal fluids vent diffusely from rocks located within 4 to 200 m of the ongoing eruption ... Despite the harsh chemical environment and regular renewal of substrate, active microbial populations at levels above ambient seawater were found in all low-temperature fluids, including those with pH less than or equal to 3."; Merle et al. (2008): tows t08c16 and t08c17; 2009 and 2010 cruise websites, accessed 24 April 2015,; 2012 cruise blog, accessed 24 April 2015, "September 19 (Q-327) was the first at West Mata volcano since the 2009 response cruise that discovered an active eruption ... No sign of eruptive activity was observed during the dive"; temperature categorized as Low based on observations during 2012 cruise; WHOI YouTube video, accessed 24 April 2015,
Notes Relevant to Biology: 
2009 cruise blog, accessed 24 April 2015, "the diffuse venting fluids (5 to 25 C), issuing through cracks and crevices around the eruptive vents, play host to only one type of vent fauna - shrimp"; Resing et al. (2011): "Two co-occurring vent-endemic alvinocarid shrimp species (Opaepele loihi and an unidentified species)"; 2012 cruise blog, accessed 24 April 2015, "ecosystem at West Mata was dramatically changed from the relatively sparse single shrimp species population observed in 2009 to multiple species of shrimp swarming in high- density clusters over the summit region. In addition, other motile species including scale worms and crabs had colonized the volcano"; video of shrimp, dive Q332, accessed 24 April 2015,; Baker et al. 2019: site 39 in Table 2;
