Yale geology and geophysics professor Ruth Blake recently completed a tour of duty as lead scientist aboard the exploration vessel Nautilus, during the Windward Passage leg of the ship’s 2014 exploration season.

The Windward Passage is the body of water between Cuba and Haiti, where the Atlantic Ocean flows into and exchanges water with the Caribbean Sea. Blake’s stint as lead scientist lasted Aug. 18–28.

Blake spoke with YaleNews about the scientific mission at the heart of the journey. (more…)

Exoplanet study finds ‘super-Earths’ likely have oceans and continents

Massive terrestrial planets, called “super-Earths,” are known to be common in Earth’s galaxy, the Milky Way. Now a Northwestern University astrophysicist and a University of Chicago geophysicist report the odds of these planets having an Earth-like climate are much greater than previously thought.

Nicolas B. Cowan and Dorian Abbot’s new model challenges the conventional wisdom, which says super-Earths actually would be very unlike Earth—each would be a waterworld, with its surface completely covered in water. They conclude that most tectonically active super-Earths—regardless of mass—store most of their water in the mantle and will have both oceans and exposed continents, enabling a stable climate such as Earth’s.

*Projections for the future still loom large*

The seas are creeping higher as the planet warms. But how high could they go?

Projections for the year 2100 range from inches to several feet, or even more.

The sub-tropical islands of Bermuda and the Bahamas are two seemingly unlikely places scientists have gone looking for answers. (more…)
