Tiny bubbles talk photosynthesis.
- During photosynthesis, algae produces a symphony of little "pings."

There might be hope for our oceans, thanks to one clumsy moment in a coral tank.
- David Vaughan at the Mote Laboratory is growing coral 40 times faster than in the wild.
- It typically takes coral 25 to 75 years to reach sexual maturity. With a new coral fragmentation method, it takes just 3.
- Scientists and conservationists plan to plant 100,000 pieces of coral around the Florida Reef Tract by 2019 and millions more around the world in the years to come.

The modern ocean can be a dangerous place for whales.
- September 11th, 2001, offered researchers a unique opportunity to study whales' behavior in the absence of commercial shipping.
- Their findings contribute to a growing understanding of how hostile an ocean filled with ships can be for whales.
