Discovery of the first hydrothermal field along the 500-km-long Knipovich Ridge offshore #Svalbard (the Jøtul field) https://www.nature.com/articles/s41598-024-60802-3

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

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.

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.

#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.

Researchers have discovered a deep-sea hydrothermal vent field near Svalbard, a Norwegian archipelago within the Arctic Circle. The area was previously assumed to be geologically inactive, Live Science reports:

"The #worm is found on the sides of #hydrothermal vents, with its tube often reaching across the chimney to access some of the hottest fluids. The #worms can be briefly exposed to 100˚C waters, although temperatures adjacent to the worm’s tubes more often range between near freezing and 45˚C. The rear end likely experiences extreme heat while the front end experiences extreme cold"
