Annual wrack biomass of the northern Portugal sandy beaches

Wrack accumulations are a source of nutrients on sandy beaches and host invertebrate species, increasing local biodiversity. The distribution of these important accumulations varies in space and time depending on the environmental conditions of the area and the biological factors of the species that compose it. Consequently, this spatio-temporal variability in the wrack accumulations remains poorly understood in some regions. This database compiles the monthly variability in dry weight biomass of six seaweed taxa(Saccorhiza polyschides, Fucus spp., Ascophyllum nodosum, Cystoseira spp., Ulva spp. and Sargassum muticum) which forming the wrack of four sandy beaches in the northern Portugal (Âncora, Cabedelo, Paramos and São Pedro de Maceda)through a year.

沙滩上的残骸积累是沙质海岸带的重要营养源，并成为多种无脊椎动物的栖息地，从而丰富了当地的生物多样性。这些关键积累物的分布随空间和时间的变化而有所不同，这取决于该地区的环境条件以及构成该积累物的物种的生物学因素。因此，在某些地区，残骸积累的这种时空变异性仍然没有得到充分理解。本数据库收集了葡萄牙北部四座沙滩（Âncora、Cabedelo、Paramos和São Pedro de Maceda）上由六种海藻类群（Saccorhiza polyschides、Fucus spp.、Ascophyllum nodosum、Cystoseira spp.、Ulva spp.和Sargassum muticum）形成的残骸在一年内的干重生物量月度变异性。
