Descrição
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).
Registros de Dados
Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 140 registros.
Também existem 2 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
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.

Descrição dos passos do método:
- 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.
