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.

The second dataset was developed with the objective of the ecological status assessment in marine areas where sewage outfall discharges were projected. For this purpose, several field campaigns were carried out along the north coast of Spain (Avilés, Gijón, Saja-Besaya, Santander, Santoña, Urdaibai and San Sebastián-Pasajes) between 1998 and 2003. In each of these sites transects perpendicular to the coast were established. Then, samples were taken both in the intertidal and shallow subtidal to obtain the biomass of macroalgae taxa. The main characteristic and canopy taxa of the area were selected: Bifurcaria bifurcata, Cystoseira baccata, Cystoseira tamariscifolia, Gelidium corneum, Gelidium spinosum, Laminaria hyperborea, Laminaria ochroleuca, Saccorhiza polyschides and Stypocaulon scoparium.

<p>IHCantabria with the support of the Regional Government of Cantabria has been carried out since 2005 the monitoring of the coastal waters of Cantabria in accordance with the Water Framework Directive. Here is included the abundance and biomass of estuarine fishes obtained from field campaigns in all the estuaries of the region.</p>

<p>The number of marine seaweeds outside their natural boundaries has increased in the last decades generating impacts on biodiversity and economy. This makes the development of management tools necessary, where species distribution models (SDMs) play a crucial role. SDMs can help in the early detection of invasions and predict the extent of the potential spread. However, modelling non-native marine species distributions is still challenging in terms of model building, evaluation and selection. This product aims to predict the European distribution of four widespread introduced seaweed species (Asparagopsis armata, Caulerpa Taxifolia, Sargassum muticum and Undaria pinnatifida) selecting the best model building process.</p>

IHCantabria with the support of the Regional Government of Cantabria has been carried out since 2005 the monitoring of the coastal waters of Cantabria in accordance with the Water Framework Directive. Here is included the abundance and biomass of soft bottoms invertebrates obtained from field campaigns in the coast and the mouth of the two biggest estuaries.
