Abstract

Bahamian whitings, floating patches of lime mud, are in part the result of biological precipitation of calcium carbonate induced by picoplankton and cellular components. The cells may act as nucleation sites for crystallization from seawater supersaturated with CaCO 3 . Mineralization occurs on the surfaces of picoplankton cells and degrading organic cellular components. The organic constituents include, but are not restricted to, whole and fragmented algal cells and composite structures ~20-30 μm in diameter. -from Authors
