Formazioni sottomarine · Frattura eruttiva

Unnamed submarine volcano in the Pacific Ocean

Northern EPR at 10.7°N

Tipo
Frattura eruttiva
Altitudine
2900 m (sottomarino)
Ultima eruzione
2003
A temperature probe from the submersible vehicle Alvin collects data at a low-temperature hydrothermal vent located in a collapse structure in the East Pacific Rise area. The maximum temperatures reached only 9.5°C. This lava flow was erupted within only a few weeks to a few months of this November 2003 expedition. The flow was covered by bacterial mats, had large amounts of bacterial floc issuing from diffuse vents, and was sparsely populated by small animals.
