Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An opening in the sea floor out of which heated mineral-rich water flows.
- ‘It has even been identified in deep-sea hydrothermal vents on the eastern Pacific Ocean floor.’
- ‘The most well-known biological hot spots are hydrothermal vents, which spew black, mineral-enriched, scalding water from deep beneath the Earth's crust.’
- ‘Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents.’
- ‘It has been found that seeps have lower temperatures and lower flow rates than hydrothermal vents.’
- ‘If hydrothermal vents were closer to the surface, mining copper, manganese, and even gold from them could be quite profitable, but they are far too deep in the ocean for this to be profitable.’
- ‘His specialty involves one of the newest discoveries in ocean science: hydrothermal vents, where ocean water seeps through cracks in underwater-volcano lava, becomes heated, and releases back into the cold water above.’
- ‘One example is the current quest to identify deep-sea hydrothermal vents within the Arctic Ocean.’
- ‘I am talking about a series of hydrothermal vents on the floor of the deep ocean.’
- ‘In the dark ocean depths, kilometers beneath the waves, scalding water spews from hydrothermal vents as it has for billions of years.’
- ‘The purpose of the journey was to observe the life that masses around hydrothermal vents or black smokers.’
- ‘It's conceivable that whale worms first appeared on whales and later adapted to deep-sea hydrothermal vents,’ Smith explains.’
- ‘Analyses of mineral deposits in and around a unique set of hydrothermal vents beneath the Atlantic Ocean suggest that the site's tallest towers of minerals have been growing for at least 30,000 years.’
- ‘Reduced metals and sulphides are also a major source of energy for bacterial communities at hydrothermal vents at ocean ridges.’
- ‘When scientists last month tried to revisit an undersea hydrothermal vent that was first discovered nearly a quarter of a century ago, they were in for a shock.’
- ‘Furthermore, deep sea hydrothermal vents may have been protected from meteorite bombardment that could have made it difficult for very early life on the surface of Earth to survive.’
- ‘That raises the tantalizing possibility that life on Earth began at such hydrothermal vents in the early ocean, rather than in shallow waters at Earth's surface.’
- ‘Were they isolated from deep-sea hydrothermal vents?’
- ‘The circulation of fluids that forms this new class of hydrothermal vents apparently is driven by heat generated when seawater reacts with mantle rocks, not by volcanic heat.’
- ‘Earth's caves and deep ocean hydrothermal vents sustain rain forest-like biodiversity without the benefit of sunlight.’
- ‘The unusual composition of the lava is reflected in the chemistry of the water coming through the hydrothermal vents.’
