Description
Monitoring data from Flemish rivers and channels. The data contains phytoplankton counts of Flemish lakes and pools. Water bodies were monthly sampled during the growing season of a one-year period, from a bridge of the shore using a bucket. Each time, a 250ml subsample fixed using 125µl alcalic lugol, 6.25ml borax buffered formaldehyde (35%) and 250µm sodiumthiosulfaat (5 %).Samples were kept dark and cool until microscopic analysis, which was executed according to the European CEN-standard (EN 15204, 2006). In this method, a known volume of the sample was concentrated in a cuvet, after which different phytoplankton taxa were identified along a transect using an inverted microscope (Wild M40). When to much detritus was present, samples were coloured using Bengal red, to enable recognizing cells. For each sample, at least 250 individuals were counted, which was used to calculated to number of individuals per ml. Colonies were counted as one individual.
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 76 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
