New deep-water methane reservoir found deep in the Arctic Ocean
March 31, 2015 07:57 AM - University of New Hampshire via EurekAlert.

Research led by a University of New Hampshire professor has identified a new source of methane for gas hydrates -- ice-like substances found in sediment that trap methane within the crystal structure of frozen water -- in the Arctic Ocean. The findings, published online now in the May 2015 journal Geology, point to a previously undiscovered, stable reservoir for abiotic methane -- methane not generated by decomposing carbon -- that is "locked" away from the atmosphere, where it could impact global climate change.

"We've found an example where methane produced at a mid-ocean ridge is locked up in stable, deep water gas hydrate, preventing it from possibly getting out of the seafloor," says lead author Joel Johnson, associate professor of geology at UNH and guest researcher at the Center for Arctic Gas Hydrate, Environment and Climate (CAGE) at UiT The Arctic University of Norway in Tromsø. Johnson notes that the findings, which pinpointed a source of abiotic methane ¬produced in seafloor crust, indicate gas hydrates throughout the Arctic may be supplied by a significant portion of abiotic gas.

SPOTLIGHT

The highlight of the "Green Knesset" Project: The unveiling of the largest solar field in any parliament in the world

Editor, ENN

In the past few weeks, giant cranes have unloaded some 1,500 solar panels onto the Knesset's (the Israeli parliament) roofs. These panels were created especially for the Knesset's solar field, which is laid out over 4,650 square meters of the Knesset roofs and will have an installed capacity of 450 kilowatts. The solar array, which cost the Knesset NIS 2.4 million, will create some 10% of the Knesset's electricity, and together with additional energy-saving measures, it will help reduce the Knesset's energy use by a third.

The solar array is expected to save the Knesset NIS 300,000 every year. It will operate according to the net-metering method, under which electric energy generated by an electric consumer from an eligible on-site generating facility and delivered to the local distribution facilities may be used to offset electric energy provided by the electric utility to the electric consumer during the applicable billing period. The Knesset's solar array will be the first of any national institution to operate according to this method. Director General of the Knesset, Mr. Ronen Plot, hopes that other government institutions and local authorities will follow suit and establish solar fields of their own.
