Woods Hole Oceanographic Institute

The study is based on discovery of traces of helium with concentration that has never been detected before.

The San Jos, the largest galleon and the flagship of one group of Spanish ships that started sailing in the 16th century, was big and - thanks to 62 bronze cannons engraved with dolphins - deadly enough to deter or destroy ships, whether pirates or rival nations.

The mantle - the mostly solid, rocky part of Earth's interior - is about 60 degrees Celsius hotter than previously thought, a new study has found.

As Hermine worked its way up the East Coast, scientists deployed several underwater drones they say will help them better understand what sustains and strengthens hurricanes and tropical storms - and ultimately better protect life and property.

The blue water of Buzzards Bay glittered as boats bobbed on the gently undulating surface and gulls swooped among their sails. The seaside air at the Woods Hole Oceanographic Institution was thick with the sweet smell of grass and the tang of saltwater. This was late summer on Cape Cod - our ocean world at its most inviting.

Radiation from Japan's 2011 nuclear disaster has spread off North American shores and contamination is increasing at previously identified sites, although levels are still too low to threaten human or ocean life, scientists said on Thursday.

Never mind the sharks or the swirling ocean debris that await him, Benoit Lecomte is counting the days until his long-distance swim from Tokyo to San Francisco -- to raise awareness of environmental threats in the Pacific.

The breath samples provided scientists with DNA and hormone and bacteria measurements.
