Moving 10-years analysis of chlorophyll-a at Mediterranean Sea for each season : - winter (January-March), - spring (April-June), - summer (July-September), - autumn (October-December). Every year of the time dimension corresponds to the 10-year centered average of each season. Decades span from 1972-1981 until 2006-2015. Observational data span from 1911 to 2015. Depth range (IODE standard depths): -2500.0, -2000.0, -1750.0, -1500.0, -1400.0, -1300.0, -1200.0, -1100.0, -1000.0, -900.0, -800.0, -700.0, -600.0, -500.0, -400.0, -300.0, -250.0, -200.0, -150.0, -125.0, -100.0, -75.0, -50.0, -30.0, -20.0, -10.0, -5.0, -0.0. Data Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network. Description of DIVA analysis: Geostatistical data analysis by DIVA (Data-Interpolating Variational Analysis) tool. Profiles were interpolated at standard depths using weighted parabolic interpolation algorithm (Reiniger and Ross, 1968). GEBCO 1min topography is used for the contouring preparation. Analyzed filed masked using relative error threshold 0.3 and 0.5. DIVA settings: A constant value for signal-to-noise ratio was used equal to 1. Correlation length was optimized and filtered vertically and a seasonally-averaged profile was used. Logarithmic transformation applied to the data prior to the analysis. Background field: the data mean value is subtracted from the data. Detrending of data: no. Advection constraint applied: no.

This dataset concerns marine species from six coasts awarded with a Blue Flag from northern Crete, Greece, Eastern Mediterranean. It includes species of benthic and pelagic mega- and macro-fauna and flora. Visual census and photo-identification were applied as non-invasive recording methods. This resource was created within the INTERREG V-A Greece - Cyprus 2014-2020 project "SocioCoast" co-funded by the European Union (ERDF) and national funds of Greece and Cyprus under the grant agreement No 5050709.

This is a historical dataset that forms part of the Report on the Danish Oceanographical Expeditions 1908-1910 to the Mediterranean and adjacent seas. It includes data for the fish of the genus Lepadogaster sampled from several sites of the North Atlantic Ocean, near the English and French coasts and the Strait of Gibraltar during the years 1904-1910. The infromation extraction was based on the Table 1 of the publication and included abundance data and metadata of location, date, depth and the sampling effort. Additional information, such as the life stage, was extracted from the main text of the publication. The dataset was curated by the citizen scientists of the Zooniverse platform within the efforts of incorporating citizen science in the management of historical datasets of EMODnet Biology project. Standard quality control steps followed after this process.

This is a historical dataset by Edward Forbes regarding species of the family Ophiuridae from the Eastern Mediterranean Sea within the years 1841 and 1843. Species occurrence data is provided while temporal and spatial data is not provided for every record. The datasets regards species of the family Ophiuridae. There are four newly described species.

The sampler for the benthic assemblages was a dredge with a 20*70 cm opening. Study Extent This digitised historical dataset is part of the bigger floristical and faunistical qualitative survey "The fishery grounds near Alexandria" coordinated by Adolf Steuer. It concerns the area along the coasts of the city of Alexandria in Egypt during the year 1938. Quality Control Taxonomy checked using WoRMS (match taxa tool). Method step description: The publication "Steuer Ad., 1935. The fishery grounds near Alexandria. I Preliminary report. Notes and Memoirs No 8, Fisheries Research Directorate, Egypt" http://ipt.medobis.eu/resource?r=egyptexpeditionpreliminaryrepor was used in order to determine the localities of the present dataset.

A netted frame and a suction sampler were used to collect the samples from 25*25cm dimensioned quadrats on artificial reefs (of concrete) and floating platforms. Study Extent Greece Major Ports (Heraklion, Patra, Rhodes, Pireaus) Quality Control WoRMS match taxa tool was used to validate the accepted scientific names, their authorships and their corresponding IDs. LifeWatch & EMODnet Biology QC tool was used to assess to what extend the dataset meets the EMODnet Biology Data Quality Criteria.

This is a historical dataset, published in 1940, regarding the marine algae of Alexandria. The survey was conducted by A. H. Nasr, Assistant Director of the Marine Biological Station in Ghardaqa, Egypt and it was facilitated by the Fuad I Institute of Hydrobiology and Fisheries in Alexandria, Egypt. The dataset contains occurrence data of the algae found in the wider marine region of Alexandria within the year 1933

A historical dataset, by Edward Forbes, Professor of Botany in King's College, London. This digitised report, requested by the British Association, refers to the Mollusca and Radiata inhabiting the Aegean and the Red Sea. The data upon which this report is founded have been entirely derived from a voyage of 18 months to the Aegean. The calculations have been based upon more than 100 fully recorded dredging operations in various depths and in many localities. The digitization process concerns the Appendix of the Report, which refers to the Examples of Dredging Papers, selected in order to show the associations of species in several regions. The numerous dredging operations on which this Report is founded were all registered in a similar manner.

This is a historical dataset regarding Turbellaria species collected by professor Steurer; during his three month's stay in Alexandria. It contains large forms only, all of them being Pollycladida. Some of them could not be well determined, as they were badly preserved and not yet mature.
