Phytoplankton dataset: microorganisms associated with estuarine flocs in the Scheldt estuary (November 1997 and June 1998) [Fytoplankton dataset: micro-organismen en estuariene vlokken in het Schelde-estuarium (November 1997 en Juni 1998)]

Description
The subsurface samples that were used to compile this dataset were collected at four different stations along the Scheldt. Oxygen, salinity, temperature and turbidity were measured and also SPM, POC and chl a were determined in the lab and Bacterial density, ciliate density and nannoflagellate (HNAN) density were determined. more

The subsurface samples that were used to compile this dataset were collected at four different stations along the longitudinal estuarine axis in autumn 1997 (November 17th: sites A and C, and November 28th: sites B and D) and summer 1998 (June 10th: sites C and D, and June 12th: sites A and B). Oxygen, salinity, temperature and turbidity were measured in situ using WTW meters. Samples were stored overnight at ambient temperature (November) or were processed within 3 hours of sampling (June). Macro-aggregates in the samples were artificially recreated. After 3 hours of incubation, the flocs were allowed to settle for 5 minutes and were seperated from the supernatans by decantation. After this, analysis was performed on the replicate incubations. SPM, POC and chl a were determined and Bacterial density, ciliate density and nannoflagellate (HNAN) density were determined. Details on the sampling and analyses procedures are described in the related publications. This dataset was compiled and used in the framework of the research that was conducted by Koenraad Muylaert, described in his Phd thesis: "Muylaert, K. (1999). Distribution and dynamics of protist communities in a freshwater tidal estuary. PhD Thesis. Universiteit Gent (RUG): Gent, Belgium. 192 pp." More specifically this dataset was used to study the association of microorganisms with estuarine flocs.
