Description
The data presented in this dataset derives from visual surveys done along the Northwestern Iberian rocky intertidal in 2020 and 2021, focusing on 35 macroalgae species. To detect recent distributional shifts in Northwestern Iberia, we selected, based on literature available, cold-water species that historically had their southern distributional range in the western Iberian Peninsula, and, conversely, warm-water species that had their northern distributional range in the same region. In addition, invasive species were also surveyed.
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 78 records.
1 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.

Project Data
This work aims at providing a comprehensive picture of the distribution and abundance of a selected group of intertidal macro-algae along the Northwestern Iberia rocky coast in 2020/2021.

| Funding | This study was funded by FEDER through COMPETE (POCI-01-0145-FEDER-031088) and through POR Norte (NORTE-01-0145-FEDER-031053), by National Funds through FCT (PTDC/BIA-BMA/31088/2017 and PTDC/BIA-BMA/31053/2017), and by the European H2020 project FutureMARES (Grant No. 869300). |
| Study Area Description | Data were collected from the autumn of 2020 until the summer of 2021. Sampling was carried out at 71 wave-exposed rocky shore locations along the Northwestern Iberian coast, covering three major rocky stretches of shoreline in the Galicia, Northern Portugal and Central Portugal. |
| Design Description | Specimens in this dataset were observed during field work carried out between autumn of 2020 and summer of 2021. Observations derive from visual surveys done along the Northwestern Iberian coast. The occurrence and abundance of all taxa were recorded in situ. A semi-quantitative estimation of abundance was assigned to each taxa identified during the survey. We used a modified version of the scale established by Crisp and Southward 1958 — SACFOR, where abundances were encoded from 6 to 0 (where 6 means Superabundant; 5, Abundant; 4, Common; 3, Frequent; 2, Occasional ; 1, Rare; and 0, not found). |

Sampling Methods
Specimens in this dataset were collected in field work carried out between the autumns of 2020 and the summer of 2021. Observations derives from visual surveys done along the Northwestern Iberian coast. A semi-quantitative estimation of abundance was assigned to each taxa identified during the survey. We used a modified version of the scale established by Crisp and Southward 1958 — SACFOR, where abundances were encoded from 6 to 0 (where 6 means Superabundant; 5, Abundant; 4, Common; 3, Frequent; 2, Occasional; 1, Rare; and 0, not found).
| Study Extent | Data were collected between the autumn of 2020 and the summer of 2021. Sampling was carried out at 71 wave-exposed rocky shore locations along the Northwestern Iberian coast, covering the three major rocky stretches of shoreline in the Northern, Central Portuguese regions and in Galicia. |

| Quality Control | In addition to AlgaeBase (Guiry and Guiry 2021), authoritative identification guides and keys for the Eastern Atlantic and Mediterranean were used. Specifically, Araujo et al., 2009; Araújo et al., 2011; Aziza et al., 2008; Bárbara, 2009, 2013; Benita et al., 2018; Bunker et al., 2017; Campbell et al., 1994; Chapman & Goudey, 1983; M Edwards et al., 2012; Faes & Viejo, 2003; Molenaar et al., 1996; Poza et al., 2017; Stuart et al., 1999; Vieira et al., 2010. All scientific names were standardized against the WoRMS - The World Register of Marine Species using the Taxon Match tool available at http://www.marinespecies.org/aphia.php?p=match (accessed on: 2021-07-07). |
Method step description:
- The steps that led to the final release of the dataset were as follows: (1) In-situ identification of species and attribution of a semi-quantitative abundance SACFOR score; (2) standardisation of taxonomy against the World Register of Marine Species.
