This cooling effect on the ocean surface usually lasts for several years as the lifetime of sulfate aerosols is about 2–3 years. [1] However, in the subsurface ocean the cooling signal may persist for a longer time and may have impacts on some decadal variabilities, such as the Atlantic meridional overturning circulation (AMOC).

Satellite view of a pumice raft from an undersea eruption in Tonga. Volcanic eruptions can have various impacts on maritime transportation. When a volcano erupts, large amounts of noxious gases, steam, rock, and ash are released into the atmosphere; fine ash can be transported thousands of miles from the volcano, while high concentrations of coarse particles fall out of the air near the ...
Mid ocean ridges for example are the most active volcanic systems on Earth but roughly only 5% of their length has been studied in detail. [ 2 ] Initial knowledge of these eruptions came from volcanic rocks being recovered from the ocean floor when repairs were made to the Transatlantic telegraph cable in the 1800s. [ 3 ]

Photos show Icelandic volcano erupting for 10th time in 3 years Lava spurts and flows after the eruption of a volcano in the Reykjanes Peninsula near Grindavik, Iceland, in this handout picture ...
The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1] Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption.
Mount Kanlaon, a 2,435m volcano, has erupted over 40 times since 1866. It last erupted in June this year, sending hundreds of villagers to emergency shelters. Another eruption in 1996 killed at ...
A wide variety of volcanic processes can produce tsunamis. This includes volcanic earthquakes, caldera collapse, explosive submarine eruptions, the effects of pyroclastic flows and lahars on water, base surges with accompanying shock waves, lava avalanching into the sea, air waves from explosive subaerial eruptions, avalanches of cold rock, and avalanches of hot material.
