Caption: SEM photograph of a contourite sample showing clean planktonic formainiferal surface caused by winnowing away of muddy sediment by vigorous bottom currents (see Geology, v. 10, p. 231-235 and this issue p. 58). Growth of halite crystals is due to evaporation when sample was brought to surface from seafloor. Off Great Bahama Bank. University of North Carolina Collection. SEM photograph by G.
