They were able to take an accurate temperature reading of the active vent (the previous dive's thermometer had melted) and recorded a temperature of 350 °C (623 K; 662 °F). [11] They continued searching for more vents along the East Pacific Rise between 1980 and 1982. [citation needed]
In 1993, already more than 100 gastropod species were known to occur in hydrothermal vents. [33] Over 300 new species have been discovered at hydrothermal vents, [34] many of them "sister species" to others found in geographically separated vent areas.
A deep-diving robot that chiseled into the rocky Pacific seabed at a spot where two of the immense plates comprising Earth's outer shell meet has unearthed a previously unknown realm of animal ...
hydrothermal vent. Hydrothermal vents were discovered in 1977 by scientists from Scripps Institution of Oceanography. So far, the discovered hydrothermal vents are all located at the boundaries of plates: East Pacific, California, Mid-Atlantic ridge, China and Japan.
Samples from the Endeavour Hydrothermal Vents off the southwest coast of British Columbia showed that active venting black smokers had viral abundances from 1.45×10 5 to 9.90×10 7 per mL, with a drop-off in abundance found in the hydrothermal-vent plume (3.5×10 6 per mL) and outside the venting system (2.94×10 6 per mL).
In a series of eight dives conducted by Pisces IV, the scientists discovered a vibrant hydrothermal vent community on the leading edge of a 300 m (984 ft) fissure within the caldera. Vent temperatures were measured around 35 °C (95 °F), approximately 30 °C (54 °F) hotter than the surrounding environment. [16]
The bomb, found resting on a steep slope nearly 2,500 ft (760 m) deep, was located by Alvin but the submersible had difficulty raising it up, initially causing it to fall deeper to 2,800 ft (850 m). The bomb was eventually raised intact on April 7 by a Navy CURV-I and the experience gained by the Alvin crew's 34 dives with over 220 hours logged ...
In 1977, Corliss, Richard von Herzen, and Robert Ballard led a project using the DSV Alvin submersible to look for the presumed hydrothermal vents near the Galápagos Islands. Corliss, Tjeerd van Andel, [ 1 ] [ 2 ] and pilot Jack Donnelly were the crew of the Alvin to first discover the vents and the unexpected community of living creatures ...
