Diatom migration and sediment armouring – an example from the Tagus Estuary, Portugal

  title={Diatom migration and sediment armouring – an example from the Tagus Estuary, Portugal},
  author={Trevor J. Tolhurst and Bruno Jesus and Vanda Brotas and David M. Paterson},
This study measured sediment stability, colloidal and total carbohydrate and chlorophyll a in the upper 2 mm of the sediment over a whole emersion period (0800–1140) in the Tagus estuary, Portugal on the 18th April 2000. Low-temperature scanning electron microscopy (LTSEM) time series images revealed the migration of microalgae throughout the emersion period, including their appearance at the sediment surface at the beginning of emersion and their subsequent return below the surface at the end… CONTINUE READING
