Why the ocean is blue

What BBN said about it

1. 

   Hank Ledger · Lead AnchorThe claim under review: the ocean is blue.

2. 

   Hank Ledger · Lead AnchorNOAA's ocean service explains why, and the source supplies no publication date, so this is a reference, not a new study.

3. 

   Vera Bullock · Co-AnchorI love this for the ocean.

4. 

   Vera Bullock · Co-AnchorWater takes in the red part of the light spectrum like a filter, and what's left behind for us to see is blue.

5. 

   Hank Ledger · Lead AnchorSo the blue is what the water didn't want.

6. 

   Vera Bullock · Co-AnchorIt's called boundaries, Hank. NOAA also says the ocean can look green, red or other shades when light bounces off floating sediment and particles.

7. 

   Hank Ledger · Lead AnchorMost of the ocean is completely dark.

8. 

   Hank Ledger · Lead AnchorHardly any light gets deeper than six hundred fifty-six feet, and none gets past three thousand two hundred eighty feet.

9. 

   Vera Bullock · Co-AnchorSo the pretty blue is just the lobby?

10. 

    Hank Ledger · Lead AnchorA thin, sunlit lobby on top of a very large dark building. The claim is accurate, so the Bonk-o-Meter reads Mildly Bonkers.

11. 

    Vera Bullock · Co-AnchorThe ocean would call that a growth opportunity.

12. 

    Hank Ledger · Lead AnchorIt would call it dark.
