The Study: «The Sequestration of Ethane on Titan in Smog Particles» by Donald M. Hunten, published in the journal Nature.

Hunten contends that molecules of ethane can't form droplets, so they instead cling to smog particles in Titan's atmosphere.

By also measuring levels of ethane (C2H6) and perchloroethylene, or perc, (C2Cl4) the researchers determined that these pulses in methane levels during this period could be linked to major forest fires, such as the massive burn in Indonesia from late 1997 to early 1998.

The oceans of ethane and methane found on Titan may be bubbling with nitrogen — which could explain a mysterious disappearing island spotted on its surface

In the new paper, published in the journal Environmental Research Letters, Höglund - Isaksson estimated global methane emissions from oil and gas systems in over 100 countries over a 32 - year period, using a variety of country - specific data ranging from reported volumes of associated gas to satellite imagery that can show flaring, as well as atmospheric measurements of ethane, a gas which is released along with methane and easier to link more directly to oil and gas activities.

Since 2006, he has worked with NOAA's air sampling system that uses glass flasks to collect atmospheric samples from 44 different sites around the world to track the annual increase of ethane and other so - called volatile organic compounds in the air.

There has been evidence to support this with the spectroscopic discovery of ethane and later the presence of ethylene and acetylene solids on Makemake's surface.

[76] They also note that the relatively low price of ethane would give United States manufacturers an essential advantage over many global competitors.

[75] The American Chemistry Council determined that a 25 % increase in the supply of ethane (a liquid derived from shale gas) could add over 400,000 jobs across the economy, provide over $ 4.4 billion annually in federal, state, and local tax revenue, and spur $ 16.2 billion in capital investment by the chemical industry.

The engineering is even trickier because, unlike the nearly homogeneous water in earth - based oceans, the concentration of ethane and methane can vary dramatically in the Titan oceans and change the liquid's density properties.
