Theory of Hydrothermal Systems

Annual Review of Earth and Planetary Sciences, 1984
Hydrothermal systems are sets of processes that redistribute energy and mass in response to circulating H20 fluids. These systems are active today in the oceanic and continental crusts, and their fossilized equivalents constitute a substantial portion of the geologic record.

Eukaryotic organisms of continental hydrothermal systems

Extremophiles, 2019
Continental hydrothermal systems are a dynamic component of global thermal and geochemical cycles, exerting a pronounced impact on water chemistry and heat storage. As such, these environments are commonly classified by temperature, thermal fluid ionic concentration, and pH.

Biological Potential of Martian Hydrothermal Systems

Astrobiology, 2003
A source of energy to power metabolism may be a limiting factor in the abundance and spatial distribution of past or extant life on Mars. Although a global average of chemical energy available for microbial metabolism and biomass production on Mars has been estimated previously, issues of how the energy is distributed and which particular environments ...

Short-Term Operation of Hydrothermal Systems

IFAC Proceedings Volumes, 1987
Abstract The objective of short-term operation is to produce a daily schedule for each reservoir that meets the system operating constraints (water balance, bounds on volumes and outflows) and the generation targets established by longer-term scheduling models.
