Descrição
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.

Métodos de Amostragem
Sampling was performed with a 0,1 m2 Smith-McIntyre grab by bathymetry level (10, 20, 40 and 50 m) along three transects perpendicular to the coast (distance between each 2 transects: 1/4 NM). In each of the 15 sampling sites, two grab samples were collected. The content of one grab was used for grain size and total organic matter analysis, while the content of the other grab was used for faunal analysis (composition and abundance). The samples for sediment analysis were kept refrigerated until moved to the laboratory. The samples for faunal analysis were gently washed on board over a 1 mm mesh size sieve. The sorted specimens were preserved in 4% buffered formalin or 70o alcohol (crustaceans).
Área de Estudo | Sampling was performed in May 2001 during one single campaign covering an area potentially suitable for beach nourishment in the infra and circalittoral sandy bottoms off Pulga Beach, Ericeira, located in central mainland Portugal. |
---|---|
Controle de Qualidade | The sampling procedures were carried out according to Gaudêncio et al (1991). |
Descrição dos passos do método:
- Two grab samples for abiotic and biotic characterisation respectively were collected in each of the 15 sampling sites.
