Ocean Sciences:

1. A Comprehensive Estimate on the Entropy Budget in the Ocean

An analysis of the energy budget in the ocean estimates the Carnot work to be 110 terawatts and the ocean's Carnot efficiency to be 0.86%.

2. Huge Global Tsunami Followed Dinosaur-Killing Asteroid Impact

The cataclysmic Chicxulub impact roughly 66 million years ago spawned a tsunami that produced wave heights of several meters in distant waters, new simulations suggest.
