Description
The dataset provides a quantitative list of the macrozoobenthic taxa collected in the infra and circalittoral sandy bottom off Ericeira (central Portugal) in May 2001. The fauna was identified to species or family level. The aim was to characterize the macrozoobenthic composition of sandy sediments potentially suitable for beach nourishment, in order to assess the environmental impact of the dredging operations on the benthic communities
The increasing erosion along the Portuguese coast led to the definition of priority areas for beach nourishment. In order to assess the impact of the dredging operations on the benthic communities off Ericeira (a potential area for sand extraction) IPMA was appointed by the National Institute of Water (INAG) to carry out a sampling survey in the infralittoral and upper circalittoral zones (10 to 50 m depth) in May 2001. The sampling gear was a 0,1 m2 Smith-McIntyre grab. Sampling was performed by bathymetry level (10, 20, 40 and 50 m) along three transects perpendicular to the coast (distance between each 2 transects: 1/4 NM). Two grab samples for abiotic and biotic characterisation respectively were collected in each of the 15 sampling sites. The macrozoobenthos was identified to species or family level and quantified. Addionally, sediment grain size distribution and organic matter content were determined.
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 19 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.
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.
