  2. @tangledwing An amazing creature! 🌊 🌋 🐌
    Big-❤️ (physically), turns toxic chemicals into energy, & builds its own plated armour out of metal:

    A wondrous being, threatened by deep-sea mining 😡

  5. #Enceladus’ subsurface ocean 🌊 has #hydrothermal vents on its seafloor. Enceladus’ ocean contains molecular hydrogen — which #NASA has called “candy for microbes” 🦠 — as well as other building blocks for life, Iike carbon dioxide and methane. It’s pretty similar to the conditions that allowed ocean life to propagate on early Earth. planetary.org/articles/where-a

  6. Earlier we saw a map of hydrothermal sites around Tharsis suggested by James Dohm. The combination of warmth and water seemed promising in the search for life (or past life). Here are more of them, suggested in 2 studies in 2005 and 2007. These are not tied to a specific mission but could guide site selection. The 'crater sites' combined impact-generated heat with signs of water and included Gale and Gusev craters (crater sites A and B).

    Now... back to human missions.

  7. Life on Mars has always been a draw, so where should we look? 25 years ago a popular idea was hydrothermal sites. As the name suggests, they combine heat and water, so obvious candidates would be volcanic areas with evidence of water. James Dohm (then at U. Arizona) mapped two sets of them, shown on this map. 1998 sites were in Thaumasia where many channels indicate water. Sites in 2000 were more widely distributed around Tharsis. None of these have been visited yet.

  8. Life recovered rapidly at site of dino-killing asteroid. A hydrothermal system may have helped

    "the crater it left behind in the #GulfOfMexico was a literal hotbed for life, enriching the overlying #ocean for at least 700,000 years... a #hydrothermal system created by the #asteroid impact may have helped marine life flourish at the impact site by generating and circulating nutrients in the crater environment."

  9. Zircon trace element evidence for early hydrothermal activity on #Mars: science.org/doi/10.1126/sciadv -> Martian #Meteorite Points to Ancient #Hydrothermal Activity: eos.org/articles/martian-meteo - the Red Planet had water, in the form of a hydrothermal system, 4.45 billion years ago, new analyses of a Martian meteorite suggest.

  10. New #hydrothermal field in the #Arctic has intense geological activity

    Discovery of the first hydrothermal field along the 500-km-long Knipovich Ridge offshore #Svalbard (the Jøtul field) nature.com/articles/s41598-024

    The Jøtul Field’s intense #methane concentrations suggest an intense interaction between magma and oceanic sediments.

  11. Perseverance Rover to Begin Long Climb Up Martian Crater Rim

    Priority regions to study at the top of the crater are nicknamed “Witch Hazel Hill” and “Pico Turquino”, which contains ancient fractures that may have been caused by past hydrothermal activity.

  12. Complex life on Earth began around 1.5 billion years earlier than previously thought, new study claims phys.org/news/2024-07-complex-

    #Hydrothermal seawater eutrophication triggered local macrobiological experimentation in the 2100 Ma #Paleoproterozoic Francevillian sub-basin sciencedirect.com/science/arti

    The study describes an episode of unique underwater volcanic activity following the collision of 2 continents, which created a nutrient-rich laboratory for the earliest experiments in complex #evolution.

    The boardwalk was damaged, but there were no reports of injury. Biscuit Basin is temporarily closed.

  14. Environmental Impacts of #Geothermal Energy

    Published Mar 5, 2013
    Union of Concerned Scientists

    "The most widely developed type of geothermal power plant (known as #hydrothermal plants) are located near #geologic#HotSpots” where hot molten rock is close to the earth’s crust and produces hot water. In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into Earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy."

    [...]

    "Some geothermal plants also produce small amounts of #mercury emissions, which must be mitigated using mercury filter technology. Scrubbers can reduce air emissions, but they produce a watery #sludge composed of the captured materials, including #sulfur, #vanadium, #silica compounds, chlorides, #arsenic, mercury, #nickel, and other heavy metals. This #ToxicSludge often must be disposed of at hazardous waste sites."

    [...]

    "Land #subsidence, a phenomenon in which the land surface sinks, is sometimes caused by the removal of water from geothermal reservoirs. Most geothermal facilities address this risk by re-injecting wastewater back into geothermal reservoirs after the water’s heat has been captured.

    "Hydrothermal plants are sited on geological “hot spots," which tend to have higher levels of #earthquake risk. There is evidence that hydrothermal plants can lead to an even greater earthquake frequency. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes. In this process, water is pumped at high pressures to fracture underground hot rock reservoirs similar to technology used in natural gas hydraulic #fracturing. (See How Natural Gas Works for more information.) Earthquake risk associated with enhanced geothermal systems can be minimized by siting plants an appropriate distance away from major fault lines. When a geothermal system is sited near a heavily populated area, constant monitoring and transparent communication with local communities is also necessary."
