Coral reefs spread in the sea. These pictures remind us beautiful sight of shiny blue southern ocean are SE (Secondary Electron) images of Si-W-O whiskers using a STEM (Scanning Transmission Electron Microscope) (Fig.a). The whiskers with the size of several hundred nano meters grow all around (Fig.b). One of whiskers has a prism-shape and another has steps of several nano meters on the surface (Fig.c, d). The bright band which extends from the lower left to upper right in the image looks like the sunlight through the seawater.

At 60th photo contest hosted by the Japanese Society of Microscopy (8APEM) in 2004.
