Gas Hydrates on Alaska's North Slope
The USGS estimates that there are 85.4 trillion cubic feet of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. This is the first-ever resource estimate of technically recoverable natural gas hydrates in the world.

Magnitude 6.4s in Pakistan
Early this morning, October 29, 2008, a magnitude 6.4 earthquake struck near Quetta, Pakistan. Twelve hours later, a second 6.4 struck in the same area. Dr. Harley Benz, Scientist-in-Charge at the USGS National Earthquake Information Center, fills us in with the details.

Farming Carbon to Help the Atmosphere and the Land
Farming Carbon to Help the Atmosphere and the LandLong-standing farming practices in California's Sacramento-San Joaquin River Delta expose fragile peat soils to wind, rain and cultivation, emit carbon dioxide (CO2) and cause land subsidence. To capture or contain the carbon, farmers would ‘grow’ wetlands.

What You Otter Know About Sea Otters - Part 3
The last week in September is known as Sea Otter Awareness Week throughout California. To bring more attention to the issues surrounding the sea otter and its ongoing recovery from near extinction, we interviewed Tim Tinker, USGS lead sea-otter researcher. Video also provided in the Transcript/Links section.

Breaking Ice in the Arctic
Do you want to know what it sounds like to break ice in the Arctic Ocean? This audio file is of the U.S. Coast Guard Cutter Healy doing exactly that. This recording was taken outside on the ship's bow, so you can hear the ice breaking on the ship and the wind in the background.

Seafloor Mapping Sounds
The multibeam sends out a soft ping (12 kilohertz) and the sub-bottom profiler emits a chirp sound (3.5 kilohertz). These sound signals are sent from the ship into the seafloor and the return signals that bounce back are used to determine ocean depth. Some of you, but not all of you, will be able to hear the ping immediately (about half a second) before the chirp.
