Researchers link ice-age climate-change records to ocean salinity from PhysOrg.com

Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean, according to research published Oct. 5, 2006, in the journal Nature. The results provide further evidence that ocean circulation and chemistry respond to changes in climate.

Using the tip of an Atomic Force Microscope (AFM), it is possible to map the wave pattern of light, trapped in a so called optical resonator, with unprecedented precision. Apart from that, the AFM is also capable of playing with the light, to optimize the performance of the resonator.
