Typical vertical distribution of Synechococcus in the Gulf of Mexico. Profile was obtained during a cruise on the R/V Pelican during July of 1999 at an oligotrophic site west of Tampa Bay and outside the Florida Shelf. Cells are abundant throughout the mixed layer (here ca. 40 m thick) yet concentrations rapidly decline below.

Electron migrograph of Synechococcus WH7803 grown under 12:12 light:dark cycles at 23ºC. Cells were fixed in 2% gluteraldehyde and 1% OsO4. Grids were stained with 5% alcoholic uranyl acetate and sTable lead. Magnification = 12000X. Cell wall (PM), DNA (N), thylacoids (T) and a number of carboxysomes (V) are seen.
