Cover of Intertidal Macroalgae along the N and NW Coast of the Iberian Peninsula in 2011

Description in English

Algae were identified to the species level in situ or assigned to higher taxonomic categories when species identification was not possible. The taxa cover was obtained by photographic analysis. For this purpose, at least one photo of the grid was taken at each station. Then, the photographs were georeferenced and adjusted to the actual size of the field of view in ARCGIS. Macroalgae taxa were identified and outlined to create polygons whose areas were measured and recorded.

Abstract in English

A standardized sampling methodology was carried out in 21 sites along the N and NW Iberian Peninsula. Field surveys were carried out during the low spring tides in April 2011. At each site, three transects perpendicular to the coast were selected. A stratified and systematic sampling procedure was carried out, dividing each transect into four areas: lower intertidal, middle intertidal, upper intertidal and supralittoral. The sampling stations were distributed at equal distances, three in the lower and middle intertidal and two in the upper intertidal and supralittoral. The sampling unit was standardized using a 50 x 50 cm grid.
