Learning more about the dynamic processes ongoing at this hydrothermal vent site will help scientists better understand the amazing creatures captured in the video, which thrive in one of the most extreme environments on Earth. Because hydrothermal vents, like the Mushroom vent, are too deep for sunlight to penetrate, the microbes have had to develop novel metabolisms that utilize gases (e.g. During the Aperuption of this volcano, over 8,000 earthquakes occurred over a 24 hr period! In addition, there are two Short-Period Ocean Bottom Seismometersthat monitor earthquakes within the volcano, and the plumbing system for the vents during rise of the near boiling fluids. Next to the vent is a novel system that streams real-time temperatures to shore of the diffusely flowing fluids known as the Diffuse Vent Fluid 3-D Temperature Array. Once recovered, laboratory analyses provide major and trace element chemistry of these hot spring fluids. These instruments include an Osmosis-Based Fluid Samplerthat provides long-term sampling of diffusely venting hydrothermal fluids. In addition to the HD video camera, there are other sensors and instruments positioned around the chimney at the Cabled Array ASHES Medium-Power Junction box to help researchers learn more information about the impact that earthquakes have on hydrothermal vent fluid temperatures, chemistry, and flow rates, and the changes and behavior of macrofaunal and microbial communities that inhabit these areas. It focuses in on key areas of interest that include a small, high-temperature spigot near the base of the main chimney, the boundary between the base of the chimney and the lava-covered seafloor with snails and sea spiders, and areas hosting extremely dense assemblages of tube worms, palm worms, and limpets. During this operation, the camera images the entire face of this animal-covered chimney.
Through the course of the 14-minute video the HD camera pans, tilts, and zooms to highlight different aspects of the south side of this metal-rich chimney that vents hot spring fluids at 260☌ (500☏!). Axial is the largest and most active volcano on the mid-ocean ridge spreading center that forms the western boundary of the Juan de Fuca tectonic plate. Radiating cracks in the flow are filled with white bacterial mats and small tube worms, marking sites of diffusely flowing fluids that issue from the fractures in the basalt. The HD video focuses on the 14-foot tall actively venting hot spring deposit called ‘Mushroom’ located within the ASHES vent field on Axial Seamount.

In addition, as of November 2016, the camera records for 24 hours non-stop on the 10th and 20th of every month, and 72 hours non-stop from the 1st to 3rd of every month, to examine animal behavior, diurnal/tidal cycles, and longer-duration changes in hydrothermal flow.
