This resource has not been registered with GBIF

The monitoring at the Château du Taureau station (north Brittany - France, Western English Channel) was designed to study the influence of trophic conditions on larval development of the invasive species Crepidula fornicata. From 2009 to 2011, phytoplankton communities were monitored twice a month in the frame of a research work on Crepidula fornicata larvae. :1/ Microphytoplankton - Species abundances (according to Utermöhl method microphytoplankton abundances - number of cells per liter) ; 2/ Microphytoplankton - Species occurrences (20µm net haul, occurrence code : "1" for present).

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 252 records. 2 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.

Sampling Methods

Seawater samples are collected at 1m depth using a 5 liters Niskin bottle.

Study Extent From 2009 to 2011, samples at Château du taureau Station have been collected twice a month in the frame of a research work on Crepidula fornicata larvae.

Method step description:

  1. Microphytoplankton - Species abundances Seawater samples are collected at 1m depth using a 5 liters Niskin bottle. 250 mL subsamples were fixed with acid Lugol's solution iodine according to Sournia (1978) back to the lab and stored in dark conditions at room temperature until analysis. For analysis, a sub-sample of lugol preserved water was gently poured into a 50 mL composite settling chamber (HYDRO-BIOS, Kiel), according to the standard Utermöhl settlement method described in Sournia (1978). Quantitative analyses based on the examination of lugol preserved samples were performed between 15 days and up to 1 year after sampling. Cell counts for either the whole chamber, or half a chamber, were obtained after sedimentation, under an inverted light microscope at 400x magnification. Abundance is expressed for each taxa in number of cells per liter. Reference citation to method - Sournia A. 1978. Phytoplankton manual.
