💁🏻‍♀️ TIL: 🌡️🌋 #Yellowstone spans roughly 24 km (15 mi) of #boardwalks around its scalding #hydrothermal features, all built by hand.

Park geologists use thermal #cameras to map the hottest zones and route around them, while botanists flag rare #plants and archaeologists check for buried #artifacts before any path is laid. The process keeps millions of visitors safe without disturbing the area’s fragile #ecosystem or #history.

Life Finds a Way, Even on Inactive Hydrothermal Vents https://www.biographic.com/life-finds-a-way-even-on-inactive-hydrothermal-vents/

Inactive #hydrothermal vent microbial communities are important contributors to deep ocean primary productivity: Amanda Achberger et al. https://www.nature.com/articles/s41564-024-01599-9

"Because of their similar primary productivity levels, it turns out that both hot and cold vents play an important role in sustaining the #DeepSea environment."

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.

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.

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."

Hydrothermal eruption in Yellowstone National Park sends sightseers fleeing

A surprise #hydrothermal #explosion in #Yellowstone national park has sent sightseers running for safety,
after steam and dark-coloured rock and dirt shot up high into the sky.

The eruption happened around 10am local time on Tuesday
in #Biscuit #Basin, a collection of hot springs a couple miles north of the famous Old Faithful Geyser.

https://www.theguardian.com/environment/article/2024/jul/24/yellowstone-national-park-hydrothermal-eruption-biscuit-basin-latest-today?CMP=Share_iOSApp_Other

#Hydrothermal eruption sends tourists running in #Yellowstone

Part of #BiscuitBasin, just north of #OldFaithful, is closed after a hydrothermal explosion Tues morning.

Hydrothermal explosions occur when hot water creates bubbles of steam, leading to underground pressure that eventually bursts through the surface. …It’s not unlike the steam that builds up inside a sealed pressure cooker.
