Mariner's Travels VI

As I stated before, swath bathymetry mapping can be totally boring. It apparently can make you sail around in circles, too. But we have some really good news: The Styrofoam cups made it to the bottom of the ocean and came back up *really* tiny and perfect. Ah, science. Also found on the seafloor were

• A tectonic mess
• Not a simple spreading center
  
• A stack of pancakes
• Some donuts, hopefully not Dunkin'
  
• A Lobster

These are all made of rocks, so I guess the last one would be a "Rock Lobster"
