Pakistani geologists find mud volcanoes on island that arose from ocean emitting methane

September 13, 2011KARACHI – Scientists studying the water and sediment samples collected from the one-square-kilometer island that emerged off the Makran coast last year has found well-preserved shells of certain marine organisms that are known to survive on sulphur and methane. The island located at a distance of two kilometers from the Makran coast near the point where the Hingol River drains into the sea is reported to have been collapsed due to strong currents and winds in a similar way as happened in the case of the island that emerged in the same area in 1999. The recent appearance of the island was looked at as the re-emergence of the past island — Malan. The finding, according to the scientists, provides scientific evidence to the widely held belief that the specific area has marine reserves of methane gas. “This is the first time that we have found rocks and boulders with burrows and holes that indicates the forceful eruption of the mass. Also, the presence of huge rocks on the island led us to assume that this time the island had emerged with greater pressure, though we are not sure about the exact depth from where the mass has erupted,” said Dr A.R. Tabrez, the director general of the National Institute of Oceanography (NIO) where the samples were analyzed for dissolved oxygen, salinity, elemental composition, mineralogical composition and textural analyses. A strong correlation was found between the sediments of the offshore island and the onshore mud volcanoes,” said Dr Asif Inam, the director continental shelf project at the NIO. According to Dr Inam, the analysis of the gas sample taken from the water column of the offshore Malan Island showed that it contained methane, ethane, propane and butane. Explaining the topography of the area, Dr Inam said that it was an active seismic region where three tectonic plates — Indian, Eurasian and Arabian — were converging. “The area is required to be mapped in detail to ascertain the potentially hazardous parts. Besides, the area could be explored to overcome the energy crisis.” Explaining the significance of gas hydrates, Moin Raza Khan, the general manager (exploration) of the Pakistan Petroleum Limited (PPL), said the amount of natural gas in gas hydrate worldwide was estimated to be far greater than the entire world’s conventional natural gas resources. –Dawn

    A few degrees more increase in ocean temperature may cause a “methane-burp” as the hydrates turn into the gaseous form. This could engulf the world. Some believe that this has happened in the past and was responsible for one of the mass-extinctions.
