The experiment was designed to study long-term changes in communities strucutre in response to global change (climatic change) and local anthropogenis pressures (e.g. eutrophication). Fine sand macrobenthic communities are monitored two to five times a year at the "Pierre Noire" site. The different parameters wich are measured are (1) total and specific abundances, (2) specific richness
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 840 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.
- Event (核心)
- ExtendedMeasurementOrFact
- Occurrence
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.

取樣方法
Macrofauna is sampled using a Smith McIntyre grab covering a surface of 0.1 m2. Ten replicates are collected at each sampling date.

方法步驟描述:
- After collection, the sediment was sieved (1 mm circular mesh) and the retained material is fixed with 10 % neutralized formalin prior to analysis in the lab. In the laboratory, organisms are sorted, identified to species level and stored in a 70% ethanol solution.
