The Hellenic Centre for Marine Research (HCMR) is a governmental research organisation operating under the supervision of the General Secretariat for Research and Innovation (GSRI) of the Ministry of Development and Investments. The HCMR comprises three Research Institutes: The Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC), the Institute of Marine Biological Resources and Inland Waters (IMBRIW) and the Institute of Oceanography (IO). The Hellenic Centre for Marine Research is the Greek national agency in charge of the study and the monitoring of the marine and freshwaters (physical oceanography and marine biology). Since its inception, a team was created in Crete to monitor marine biodiversity, and to develop databases for marine biodiversity. HCMR became the Regional OBIS Node for the Mediterranean and the Black Sea in 2006, providing about 140 datasets and 34017 occurrence records. Later, the datasets from the Black Sea were removed and managed by a dedicated Regional OBIS Node. In 2013, supported by the Ministry of Research, HCMR joined the European LifeWatch network that aims at developing a distributed research e-infrastructure for biodiversity data and data observatories under the ESFRI programme. LifeWatchGreece has constituted a large network of almost all institutions in Greece working on biodiversity including terrestrial ecosystems. Among other tasks, it has in charge to continue to maintain and develop the MedOBIS node, and also to establish the National GBIF node (in progress). MedOBIS provides access to data from a wide range of sources and time periods, including new and historical data sets. It actively contributes to global scientific effort for FAIR and OPEN data. When consulting and using information and data from MedOBIS, the general citation is as follows: MedOBIS data. Mediterranean node of the Ocean Biodiversity Information System (EurOBIS). Available online at ipt.medobis.eu . When using data from MedOBIS in reports, posters, publications etc., please cite the relevant data sources.

Biofouling of ship hulls in the Port of Algiers in 2021
This dataset originated from a specific bio-surveillance field study conducted in the fishing port of Algiers during spring 2021 (Kacimi, 2021). Data was collected by scraping biological material from hard substrates like floating structures and port structures at specific stations. The dataset contains records of identified fouling species, including their taxonomic classification (across Porifera, Bryozoa, Ascidiacea), status (indigenous, non-indigenous, or cryptogenic), and estimated abundance (visual assessment or frequency). Taxonomic nomenclature was verified using the World Register of Marine Species (WoRMS). This dataset serves as a baseline for future assessments of NIS in Algerian ports, though acknowledging limitations in taxonomic coverage and sampling extent.

Eastern Mediterranean Syllidae from three locations, in Crete and Israel.
This is a combined dataset originating from two projects: NaGISA (Natural Geography in Shore Areas, a long term monitoring project following a global protocol) and a study on the Benthos of Haifa Bay. Specimens from Israel were collected on 31.5.2009 and 11.10.2009 in Haifa Bay, (Israel, Eastern Mediterranean Sea) from soft sediments of mixed grain sizes in shallow waters. Sediment samples were taken with a Van-Veen grab (KAHLSICO, model WA265/SS214) 32x35cm, volume 20 l, penetration 20 cm. The sediment was preserved in buffered formalin 10% for 3–7 days, then sieved through a 250 µm mesh sieve and subsequently stored in 70% ethanol. Specimens from Crete were collected in September 2007 and June 2008 from two sites in northern Crete characterized by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure. At each site, two vertical transects with sampling depths at 1 m, 5 m, 10 m, 15 m and 20 m were defined and five replicates were taken from each transect and depth.Samples were collected by means of SCUBA diving according to the NaGISA protocol (Iken and Konar 2003). A plexiglas frame (25 x 25 cm) with a net of 0.5 mm mesh size attached to its top opening was placed onto the rock and the surface within the frame was scraped off. The sample was collected by a manually operated suction device, supplied by air from an extra scuba tank. Large particles (>2 cm) were collected manually after suction. The samples were subsequently washed through a 0.5 mm mesh sieve, fixed and preserved in 99% ethanol. Specimens were examined under an Olympus SZx12 stereomicroscope and an Olympus BX50 microscope and identified by employing the most recent literature on Syllidae (e.g. Nygren 2004, San Martín 2003, 2005, San Martín and Hutchings 2006).

Marine impactful cryptogenic and alien species in the Greek Seas: A georeferenced dataset (1893-2020)
The GreekMarineICAS geodataset was created as part of the project ALAS: Aliens in the Aegean – A Sea Under Siege project (https://alas.edu.gr/), with the aim to assess the spatial extent and potential impacts of alien species in the Aegean Sea, and to improve our understanding of the mechanisms driving the impacts of invasive alien species on native marine ecosystems. Methodology of data compilation: Initially, an ICAS catalogue was created, including species classified as of high impact in the European Alien Species Information Network (EASIN), or as invasive or of high impact in recent review papers. A thorough search was conducted to look for information on the presence of these species in the Greek Seas. Georeferenced data, along with information on the reported date / year of sighting, depth range, abundance and habitat type were compiled using all available types of data sources, including published scientific literature, grey literature (e.g., theses, technical reports, and newspaper reports), offline databases (including records from past projects of universities, research institutes, the ELNAIS database, and citizen science initiatives), online scientific or citizen science databases (Algaebase, GBIF, OBIS, iNaturalist - only research-grade data), social networks (e.g., Instagram and Facebook), as well as through field work involving scientific diving and interviews with marine scientists, fishers and divers that were carried out during the ALAS project. In situ underwater sampling during the ALAS project was carried out in 2020 at 156 sites, and all sampling was conducted using non-destructive visual sampling techniques via SCUBA or free diving, down to a maximum of 20 m depth. Moreover, an unstructured interview approach was applied during the respective interviews with marine scientists, fishers and divers, while a photographic guide of the targeted ICAS was produced and provided during the interviews to enhance the species verification process. Information from social networks was specifically retrieved from the websites of diving centers, which were thoroughly checked for images of ICAS, and once relevant images were found the corresponding information was further validated through direct communication. All data were organized within an Excel spreadsheet and all duplicate records were deleted.

Distribution of macrobenthic communities of the coastal marine ecosystem of Chrysi island (Crete, Greece, Spring 2023)
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.

Polychaete fauna were sampled from bottom sediment during three seasons between autumn 2006 and spring 2007. Samples were taken during low tide from 7 stations at the eastern harbour of Alexandria (Egypt) at depths between 3 and 11 meters. 12 Polychaete species were encountered of which 3 are considered new in the Egyptian Mediterranean waters. The collected specimens were preserved at Marine Reference Collection Center of National Institute of Oceanography and Fisheries, Alexandria, Egypt.

H.Bachmann (1936) The fishery grounds near Alexandria. XIV. Phytoplankton from the Nile. Fisheries Research Directorate of Egypt, Notes and Memoirs No 22
Egyptian plankton samples for revision as to its phytoplankton content. First samples are dated in 1933 owned by Prof. Steuer, while the other samples are from the Nile area and collected by Dr. Hans Amberg, in 1904. The samples that come from the large district of the Nile prove that the Melosira in Prof. Steuer's material represents a real phytoplankton component of Nile water and not merely a passive swimming organism.

Decapods collected with epibenthic sledge from Rhodes Isl., north-eastern Aegean Sea, Greece, June 2018
The material listed here came from three sites of the Rhodian coastline, chosen according to their proximity to the Hydrobiological Station of Rhodes. It was obtained within June 2018 from the coastal shallow waters of the island, over a mixed substrate of patches of Posidonia oceanica and sand with an epibenthic sledge bearing a bag made of plankton net with 1 mm mesh size, towed from a fishing vessel of 8.25 m length and a 38 Kw engine. Most samplings took place during the early night hours.

Seagrass meadow and macrofauna communities in Southern coast of Algerian Basin (El Mellah Lagoon), 2019
This dataset is the main part of a study conducted monthly throughout 2019 at three stations selected due to their combined continental and marine influences. The study aimed to assess the health status of the El Mellah lagoon. The analysis of the spatio-temporal variation of angiosperms reveals significant changes in their distribution within the lagoon, which appear to be linked to fluctuations in the environmental conditions of El Mellah. It is observed that Zostera noltei (Hornemann, 1832) dominates the stations influenced by freshwater, while Ruppia maritima (Linnaeus, 1753) dominates the northern part of the lagoon, where the influence of marine waters is more pronounced. The invasive species Arcuatula senhousia, which was first observed in June 2019 in El Mellah, has been found attached to the leaves and rhizomes of Zostera noltei, and to a lesser extent, on the empty shells of the bivalve Cerastoderma glaucum. Since its introduction, it has dominated the bivalve community in El Mellah with a maximum density of 1321 ± 1167 ind.m-2. This phenomenon can lead to a decline in the biodiversity of the lagoon, particularly affecting the Zostera noltei seagrass and the threatened Cerastoderma glaucum species. It is necessary to conduct comprehensive studies to assess the impact of Arcuatula senhousia in the El Mellah lagoon to implement appropriate conservation and restoration measures to preserve the integrity of the ecosystem."

Polychaetes from two subtidal rocky shores of the North coast of Crete, collected for the NaGISA project 2007-2008
This dataset contains occurrence records of subtidal polychaetes (Annelida) from two midlittoral rocky shore sampling sites in northern Crete (Greece). Samples were collected for a monitoring project of midlittoral rocky shores in Crete, in the framework of the NaGISA project (Natural Geography in Shore Areas, http://www.coml.org/projects/natural-geography-shore-areas-nagisa). The two sampling sites are characterised by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure and are not impacted by detectable anthropogenic activity. At each site, five random replicate units were collected from each depth of 1m, 5m, 10m, 15m and 20m by placing a plexiglas frame (25x25 cm) on the substrate and scraping the framed area completely. The samples were then collected with an underwater suction device working with pressure from a diving bottle. Samples were washed through a 0.5 mm mesh sieve and fixed in 99% ethanol. In the laboratory, all samples were identified to the most precise taxonomic level possible, using the most recent literature for the taxon. This dataset does not contain the records for the syllid species collected during this sampling campaign. The syllid records are available as a separate dataset (together with other syllid occurrences in the Eastern Mediterranean) in the dataset "Eastern Mediterranean Syllidae", available at http://ipt.medobis.eu/manage/resource?r=easternmedsyllids.
