取樣方法

The two samples analyzed were collected using two different drags, a box corer for Master and a shipek for Maerl samples. Master sample was obtained from the first 5 cm of the sediment rendering a sample volume of 125 cm3. In the case of Maerl sample, the first 3 cm of the sediments were collected giving a sample volume of 75 cm3. Once on board, samples were stained with buffered 37% formaldehyde with Rose Bengal (1g/L) in order to distinguish between considered living (stained) foraminifera and dead (unstained) foraminifera. Samples were stored in a cool room until further processing in the laboratory.

方法步驟描述:

1. Samples were wet sieved through a 63 micrometer sieved to wash out fine particles. After sieving, samples were dried and weighted. Then, dried samples were dry-sieved into different size fractions: 1000-500, 500-250, 250-125 and 125-63 micrometers. A representative split was obtained to get a workable fraction of the whole sample using a microsplitter. Benthic foraminifera from stained and unstained assemblages were picked from each size fraction, identified and counted under a binocular microscope. Later, foraminiferal samples were stored at Marine Geosciences Department of Marine Science Faculty of Universidade de Vigo. Taxonomic identifications were validated with WoRMS (https://www.marinespecies.org/foraminifera/, Hayward et al., 2025). All data were stored in a database. The event, occurrence and measurement data were accommodated to fulfil the Darwin Core Standard. We used the Darwin Core Archive Validator tool (http://tools.gbif.org/dwca-validator/) to verify whether the dataset adhered to Darwin Core specifications. The Integrated Publishing Toolkit (IPT v3.1.7) of the Spanish node of the Global Biodiversity Information Facility (GBIF) (https://ipt.gbif.es/) was used to both upload the Darwin Core Archive and complete the metadata. Information regarding size fraction and assemblage type is available from MeasurementOrFact extension.
