Description

This dataset includes species composition and abundances of macrobenthic faunal communities along three transects of Heraklion Bay (H2, H5, H7). The H2 transect is located in the wider marine area of the wastewater treatment plant of Heraklion city. Sampling was carried out during three different sampling surveys and periods — June 2010, June 2015, and August 2024 — at different depths (10, 20, 30, 40, 50, 100 and 200 m) along the soft-bottom continental shelf, as part of different research projects (MARBEFES, Marine Biology, Biotechnology & Aquaculture, monitoring program). A detailed comparison of species composition and abundance of macrobenthic faunal diversity among different depths and sampling periods is given, thus contributing to understanding the spatial and temporal trends and changes due to multiple environmental and human-induced stress.

Couverture géographique

Three transects of seven stations (10, 20, 30, 40, 50 100 and 200 m depth) were selected as a study site. The first two stations of H2 transect are located close to the marine area of the wastewater treatment plant of Heraklion city. The selection criteria for the specific stations were primarily based on the available data from different research projects and studies performed during previous years in order to investigate the bathymetric distribution of macrobenthic faunal communities in the wider marine area of the wastewater treatment plant of Heraklion city and along the continental shelf of Heraklion Bay (sampling surveys in June 2010 and 2015 within the framework of the monitoring program for the wastewater treatment plant of Heraklion city and Marine Biology, Biotechnology & Aquaculture, respectively).

Méthodes d'échantillonnage

Three or five replicates of sediment samples were collected from each station using a Smith McIntyre grab (SMI, sampling surface: 0.1 m²) operated by the research vessel “PHILIA” of the Hellenic Centre for Marine Research. The position of each station was calculated using a FURUNO SFN-70 satellite navigator and depth was measured by SIMRAD K-400 echo sounder. In the field, the samples were sieved through a 0.5 mm sieve and preserved in 95% ethanol buffered with seawater. In the laboratory, they were rinsed again through a 0.5 mm sieve to remove any remaining fine sediment. Benthic organisms were then sorted from the sediment under a magnifying glass and then counted and identified to the lowest possible taxonomic level using a stereoscope and a microscope.

Etendue de l'étude Three transects (H2,H5,H7) of seven stations (10, 20, 30, 40, 50 100 and 200 m depth) were selected as a study site. The first two stations of H2 transect are located close to the marine area of the wastewater treatment plant of Heraklion city. The selection criteria for the specific stations were primarily based on the available data from different research projects and studies performed during previous years in order to investigate the bathymetric distribution of macrobenthic faunal communities in the wider marine area of the wastewater treatment plant of Heraklion city and along the continental shelf of Heraklion Bay (sampling surveys in June 2010 and 2015 within the framework of the monitoring program for the wastewater treatment plant of Heraklion city and Marine Biology, Biotechnology & Aquaculture, respectively).
