Abstract
  • Diatom floral analysis of 116 sediment surface samples obtained off Peru reveals a boundary in the sediments between coastal upwelling influenced sediments and sediments outside the highly productive realm. Sinuous patterns of relative abundance for meroplanktic species (Actinocyclus octonarius, Actinoptychus senarius, and Cyclotella striata/stilorum) may preserve the meander-like patterns of surface water parameters off Peru. The occurrence of loci of high abundance of diatom valves per gram of dry sediment, and the limited occurrence of Skeletonema costatam and of a species of the genus Delphineis are additional pieces of evidence that upwelled tongues of cold water have a correspondingly patchy sediment signal.
