Rubber Ducks
How do you chart water currents in the sea over very long distances?
''NASA robotics expert Alberto Behar released 90 yellow rubber ducks into the melt water flowing down a chasm in a Greenland glacier.
"Each duck was imprinted with an email address and, in three languages, the offer of a reward. If all goes well, Dr. Behar hopes that one day they will emerge 30 miles or so away at the glacier's edge in the open water of Disko Bay near Ilulissat, bobbing brightly amid the icebergs north of the Arctic Circle, each one a significant clue to just how warming temperatures may speed the glacier's slide to the sea."''

Plankton affects plate tectonics
''Common throughout Earth's waters today, photosynthetic plankton have been around almost since the planet formed. Perhaps as far back as 3.8 billion years ago, their carbon husks began piling high on the ocean floor as they died, until over time they became black shales many kilometers (several miles) thick.
...
Norm Sleep of Stanford University thinks these biologically-built rocks form huge weak areas in Earth's crust. And when plate tectonics begin stretching out a continent they are the first to break, encouraging the land mass to rip itself apart.
...
"The composition of Mt. Pinatubo and Mount St. Helens is partly biologically controlled," Sleep said.'' [source]
This is a test: the same news above are now repeated visually.
