地理的範囲

A study area of four different stations (St. 1 50, m; St. 2, 100 m; St. 3, 200 m; St. 4, 300 m isobaths) was selected. St. 1, Lat. 35.362000, Lon. 25.1000667; St. 2, Lat. 35.382883, Lon. 25.099350; St. 3, Lat. 35.422783, Lon. 25.094817; St. 4, Lat. 35.444033, Lon. 25.093717).

生物分類学的範囲

This dataset presents the identified hyperbenthic, (epi-)benthic and planktonic macrofaunal species belonging to the taxonomic groups of Crustacea, Polychaeta and Mollusca and their abundances in the different sampling periods and stations.

収集方法

As sampling apparatus, a modified hyperbenthic sledge Towed Trawl Simulator Sledge version 2, TTSS2) described in Koulouri et al. (2003), was used simulating the artificial resuspension of the sediment surface (total surface area of 0.45 m2, plankton nets with 0.5 mm mesh size). The sledge was towed from the research vessel “PHILIA” of the Hellenic Centre for Marine Research at a speed of two knots and with a length of wire paid out to depth ratio of 2:1. At station 1 (50 m isobath), three 50 m length tows were performed, while at each of the stations 2 (100 m isobath), 3 (200 m isobath) and 4 (300 m isobath), one 200 m length tow was carried out. Travelling distance of the sledge, while in contact with the seabed, was measured by an odometer and the whole process was monitored by a video-camera, both attached to the apparatus. On board, the samples were preserved in 10% formalin and sorted under a magnifying glass back in the laboratory. Furthermore, the macrofaunal organisms were identified to the lowest possible taxonomic level and counted using a stereoscope and a microscope.

Method step description:

1. 1. Two field surveys were carried out in early spring and early autumn. During daylight hours, three tows with 50 m length were performed at station 1 and one tow of 200 m length at stations 2,3 and 4. St. 4 was only sampled in early autumn. Samples were fixed in 10% formalin after collection. 2. The macrofauna was sorted out, classified to the major taxa and counted. Furthermore, the taxonomic groups (Crustacea, Polychaeta ,Mollusca) were identified to the lowest possible taxon level and counted. Macrofaunal densities from the three replicates from station 1 were averaged. Then, all densities estimated in the samples were standardized to the number of individuals per 100 m2 of sediment surface. 3. The data were standardized according to the FAIR principles (Findable, Accessible, Interoperable and Reusable) (Wilkinson MD. et al. 2016). To secure interoperability, the dataset was formatted according to Darwin Core Archive (Wieczorek et al. 2012). For scientific valid names, the World Register of Marine Species with its Taxon Match Tool (WoRMS Editorial Board 2026) was used and the additional measurements and associated facts were standardized with controlled terms from the NERC Vocabulary Server, enhancing interoperability across marine data repositories (BODC - British Oceanographic Data Centre 2026). In the end the dataset was tested using the LifeWatch & EMODnet Biology Quality Control tool (Perez et al. 2024).
