  • Seasonal production of siliceous phytoplankton and a seasonal flux of terrigenous clastic material produced varved sediments along the continental slope off California during the late Pleistocene to mid-Holocene. Distribution of diatoms in varves

  • The early and late Wisconsin maxima were times of prolonged annual sea-ice cover and a short cool period of phytoplankton productivity during the ice-free season. The middle Wisconsin interstade, at least in the southern Bering Sea, had greater
  • Trace metals, organics and nutrients that are adsorbed onto suspended particles affect the supply of these materials to phytoplankton and zooplankton. Fecal pellets are important in fjords, an aqueous environment that is dominated by the vertical
  • This paper evaluates the quantification of 4 types of water quality parameters : inorganic sediment particles, phytoplankton pigments, coloured dissolved organic material and Secchi disk depth. It concentrates on quantification requirements, as well
