At a depth of 1,300 meters in the Pacific Ocean, scientists have filmed a geological contradiction that wasn’t supposed to ...

Petroleum sheens on the ocean off a stretch of Southern California coast are consistent with oil from local natural seeps, but old abandoned oil wells could be a factor, authorities said Saturday. The ...

Natural gas in underground rock layers can seep to the surface—sometimes in quantities abundant enough to produce “eternal flames.” Researchers say much remains to be learned about these conditions ...

A research cruise has discovered 40 previously unknown gas seeps on the seafloor off the U.S. East Coast. The plumes of gas are almost certainly methane, also known as natural gas, according to ...

Beneath cold, high-pressure oceans, water and gas molecules clump together into crystalline solids called gas hydrates.

If you’ve been following the news lately then you’ve likely heard about the large-scale methane leak currently plaguing the city of Los Angeles. The months-long environmental disaster stemmed from an ...

The Okeanos Explorer was a U.S. Navy ship before becoming NOAA's only large vessel dedicated to exploring oceans and making discoveries. (Ellis Berry/KUCB) The Okeanos Explorer docked in Unalaska last ...

A technology commonly used to map the bottom of the deep ocean can also detect gas seeps in the water column with remarkably high fidelity, according to scientists. This finding, made onboard the NOAA ...

Table 1 Deep-seawater, methane data, DOC data and isotope mass-balance model results. Figure 1: Radiocarbon (14 C) and 13 C properties of DOC plotted versus DOC concentration from deep sea water ...

The hydrothermal vents and methane seeps on the ocean floor that were once thought to be geologic and biological oddities are now emerging as a major force in ocean ecosystems, marine life and global ...
