Methane Maps Step One for Energy Prospectors

From Popular Mechanics:

A team of geologists recently found hundreds of plumes of methane gas—a potent greenhouse gas and potential energy source—in the Arctic Ocean, indicating there may be more methane being released from deep in the ocean than expected. Here is a look at the recent findings and the known sources of methane out today.

An international team of scientists has found hundreds of methane gas plumes in the depths of the Arctic Ocean. German and English researchers used sonar to detect 250 columns of bubbles pushing out of the seabed of West Spitsbergen and then sampled the water in those areas, finding that the gas was predominantly methane. The discovery indicates there may be more of the gas being released and from deeper areas of the Arctic seabed than expected.
