Descripción
This study is the first to examine the species composition and population density of macrobenthic communities living in soft-bottom sediments within the sublittoral zone surrounding Chryssi and Mikronisi islands. Data were gathered from sediment samples taken during a baseline survey conducted between April 23rd and May 1st, 2023. A grid of eleven sampling stations was established around the two islands, covering water depths of roughly 10 to 30 meters, with samples collected using a Smith–McIntyre grab (0.1 m²). The sediments were predominantly coarse-to-medium and fine-to-very-fine sand, a characteristic linked to the intense hydrodynamic activity found on both the northern and southern sides of the islands. The resulting dataset offers an evaluation of soft-bottom macrobenthic community structure in the region, and forms part of a broader environmental baseline assessment conducted around Chryssi and Mikronisi islands under the project "Implementation of the Action Plan Measures for Chryssi Island," funded by the Region of Crete / Sub-Regional Unit of Lasithi.

Métodos de muestreo
At each station, one sediment sample was collected using a quantitative Smith–McIntyre grab with a sampling surface of 0.1 m². The location of each station was recorded with a FURUNO SFN-70 satellite navigator, and water depth was measured using a SIMRAD K-400 echo sounder of the research vessel PHILIA of the Hellenic Centre for Marine Research (HCMR). Samples were sieved on board through a 0.5 mm mesh and preserved in 75% ethanol buffered with seawater. Back to the laboratory, macrobenthic organisms were extracted from the sediment, counted, and identified to the lowest possible taxonomic level using both a stereoscope and a microscope.
| Área de Estudio | A grid of 11 stations at Chryssi island was established to assess the qualitative and quantitative composition of the main macrobenthic faunal groups inhabiting soft-bottom substrates. |
|---|---|
| Control de Calidad | All samples were processed following a consistent protocol, and species identifications were cross-validated by expert taxonomists. Data management adhered to the FAIR principles (Findable, Accessible, Interoperable, Reusable), ensuring that both metadata and datasets were machine-actionable and appropriately connected through persistent identifiers and established community standards (Wilkinson et al., 2016). Taxonomic and occurrence data were standardized using Darwin Core terms, a globally recognized framework for structuring and exchanging biodiversity information (Wieczorek et al., 2012). Scientific names were harmonized through the World Register of Marine Species (WoRMS) using the Taxon Match tool (WoRMS Editorial Board, 2025). Additional measurements and contextual information were standardized using controlled vocabularies from the NERC Vocabulary Server, improving interoperability across marine data repositories (BODC, 2025). Finally, the dataset underwent validation with the LifeWatch & EMODnet Biology Quality Control Tool (Perez et al., 2024), which assesses Darwin Core Archive files against EMODnet Biology data quality criteria. |
