Figure F7. Accumulation rates (solid line upper axes) and relative abundances (shaded area, lower axes) of the marine diatom groups present at Site 1077. Diatom groupings follow van Iperen et al. (1987) and Romero et al. (1999a). The scale for accumulation rates is valves 107/cm2/k.y. for the littoral and the warm groups; all other scales are valves 108/cm2/k.y.
