Excerpt:

Even four times as deep as most scuba divers venture, the Great Barrier Reef blooms. A new exploration by a remote-operated submersible has found the reef's deepest coral yet. The common coral Acropora is living 410 feet (125 meters) below the ocean's surface, a discovery that expedition leader Pim Bongaerts of the University of Queensland called "mind-blowing." The group had previously seen the coral living in the reef at a depth of about 200 feet (60 m). Coral reefs are made of colonies of polyps which secret a rock-like exoskeleton. The polyps have a symbiotic relationship with algae that provide them nutrients using photosynthesis. Because this process requires light, coral reefs thrive in clear, relatively shallow water. "The discovery shows that there are coral communities on the Great Barrier Reef existing at considerably greater depths than we could have ever imagined," Bongaerts said in a statement.

"This poses lots of questions for us, but now we have specimens, we'll be able to analyze them much more closely and can expect our findings to reveal a far greater understanding of just what is going on to enable reef corals to survive at such extreme depths."

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
