Steuer Ad., 1935. The fishery grounds near Alexandria. I Preliminary report. Notes and Memoirs No 8, Fisheries Research Directorate, Egypt

This digitized historical paper contains information about the floristical and faunistical survey of the coasts near Alexandria (Egypt) including lake Edku, lake Mareotis and Suez canal that was made by Adolf Steuer in summer and autumn of 1933. It contains specific information and description of the sampling protocol that was followed, for the collection of plankton and benthos. It is also contains detailed description of the habitats and the bionomic division at Alexandria and contains three charts that show the location of benthic and planktonic stations. The digitization of this report was made by LifewatchGreece team.
Sampling Methods: In general, all excursions were one-day trip. The motor-launch of the Marine Laboratory "El Hoot" about 15 meters long was used for dredging. The isobath of 200 meters was surpassed only at a few points. A rowing boat in shallow water and during favorable conditions was also used. For excursions along the coast, near Rosetta, Lake Mariout and Lake Edku the motor car of the Laboratory was used. For plankton samples only medium sized nets with celluloid buckets with gauze bottom were available. 19 stations were sampled for plankton once or several times. For bottom samples almost exclusively a dredge with 20x70 cm opening was used. A single catch was made in a depth of 20 m with a large otter trawl in the eastern part of the Bay of Abukir. Almost 150 stations were bottom sampled.

Modeled distribution map of discrete Lophelia pertusa colonies in the North East Atlantic in 2021

Species distribution models (GAM, Maxent and Random Forest ensemble) predicting the distribution of discrete Lophelia pertusa - Desmophylum pertusum colonies assemblage in the Celtic Sea. This community is considered ecologically coherent according to the cluster analysis conducted by Parry et al. (2015) on image samples. Modelling its distribution complements existing work on their definition and offers a representation of the extent of the areas of the North East Atlantic where they can occur based on the best available knowledge. This work was performed at the University of Plymouth in 2021.

Turbulence microstructure dataset from Slocum Glider Teresa (Western Mediterranean, 2015–2024)

We present a comprehensive dataset of turbulence microstructure measurements collected with a Micro Rider (MR-1000) from Rockland Scientific (RS) mounted on the Slocum Deep Glider “Teresa” across repeated transects between Sardinia and the Balearic Islands (SMART missions, 2015–2024). This dataset constitutes one of the most extensive autonomous glider-based microstructure archives to date for the Western Mediterranean, containing glider sections up to 1000m-depth and delivering quality-controlled vertical profiles of turbulent kinetic energy dissipation rate (e) and thermal variance dissipation rate (?) across seasonal cycles and diverse water masses. The data were processed through a rigorous multilevel workflow (L0–L4), following community best practices for processing, quality control, and uncertainty quantification. Final products include estimates of e from dual shear probes and ? from dual fast thermistor probes, aligned with co-located hydrographic and oxygen measurements. This dataset provides a high-resolution resource for investigating fine-scale mixing, validating parameterizations, improving turbulence representation in models, and modeling physical processes. All data and processing codes are openly provided to support reuse, reproducibility, and integration into global efforts advancing the inclusion of turbulence as an Essential Ocean Variable.

Depth profiles of 210Pb, 226Ra, 228Th, 137Cs and 40K in marine sediments of the West Gironde Mud Patch (Bay of Biscay) collected during the JERICObent7 cruise

The West Gironde Mud Patch (WGMP) is a mud deposit located 25 km from the mouth of the Gironde Estuary in the Bay of Biscay. This 4-metre-thick clay-silt feature, which extends over an area of 420 km2, is found at depths between 30 and 80 meters. The main objectives of the JERICObent7 cruise, in July 2019, were to characterise the evolution of the WGMP’s benthic ecosystem in terms of its sedimentary, biogeochemical and ecological properties and to reconstruct climate variations and identify potential anthropogenic impacts over the last few centuries. To this end, a precise chronological framework was established for the sedimentary archives of the last few decades using 210Pbxs (T1/2 = 22.3 years). Interface cores were collected at stations 1, 3 and 4 along a cross-shelf transect. Twin Kullenberg cores were collected at sites 3 and 4 for geochemical (KGL) and palaeoceanographic (JB7-ST) investigations. Each interface core was carefully extruded at 0.5 cm intervals from the top of the core to 4 cm, and then at 1 cm intervals until the bottom was reached. Kullenberg cores were only collected at sites 3 and 4. Depending on their intended use, the Kullenberg cores were sampled at different resolutions, the depth of each sediment layer corresponded to the depth from the top of the core. These layers were then used to determine the dry bulk density and radioisotope activities of interest (210Pb, 226Ra,  228Th, 137Cs, 40K). Excess 210Pb was used to establish the realignment and chronological framework of the interface and Kullenberg cores.

Fuzzy coded longevity dataset of European marine benthic invertebrates

The ICES Working Group on Fisheries Benthic Impact and Trade-offs (WGFBIT) has developed an assessment framework based on the life history trait longevity, to evaluate the benthic impact of fisheries at the regional scale. In order to apply this framework to the Mediterranean sea, several Mediterranean longevity databases were merged together with existing North-East Atlantic ones to develop a common database. Longevity was fuzzy coded into four longevity classes: <1, 1-3, 3-10 and >10 years. Both benthic mega and macrofauna organisms are included in this dataset. Further details about both the purpose and the methodology may be found in ICES (2022) and Cuyvers et al. (2023). The result of the final dataset merging is one dataset containing the fuzzy coded average longevity (and standard deviation) for 2264 taxa and for each, the number of databases used.

PIAF project: CTD data in Corsica, NW Mediterranean, may 2023.

This dataset contains the CTD data were collected during the PIAF project (Fish inventory using environmental DNA), between 30/04/2023 and 11/05/2023, around Corsica, western Mediterranean, jointly by the Andromède océanologie [https://www.andromede-ocean.com/] (France) and MARBEC MARine Biodiversity, Exploitation and Conservation [http://www.umr-marbec.fr/en/?lang=en] (France) teams. The CTD data were obtained using RBR concerto3 autonomous logger from Victoria IV trimaran belonging to Scopra, France and chartered by the University of Montpellier. 79 transects (16 were 2.5-km long and 63 were 5-km long) were performed along the -40m isobath (34,6 m in mean, 5 m above the seabed in mean), i.e. the lower limit of the Posidonia meadow, east, south and west Corsica between latitude 41.2-43°N and longitude 8.4-9.5°E. The sensors measured and recorded conductivity (mS/cm), temperature (°C), pressure (dBar), dissolved O2 concentration (µmol/L) and turbidity (NTU). Other parameters were derived from the previous measurements: sea pressure (dbar) removing atmospheric pressure, depth (m) simplifying and using density parameter, salinity (PSU) or Practical Salinity Scale (PSS-78), speed of sound (m/s) based on UNESCO algorithm, specific conductivity (µS/cm) and dissolved O2 saturation (%). All parameters were measured or calculated at depths ranging from -5 m to -49 m (Table 1). Recordings were made every 0.5 seconds (2 Hz frequency). The accuracy, specified by the manufacturer, were ±0.003mS/cm for conductivity, ±0.002°C for temperature, ±0,1 dbar for pressure (Depth), a maximum of ±2µmol/L or ±1.5% for dissolved O2 concentration and saturation.  RBR Concerto3 was factory calibrated before. The downloadable files are a csv of CTD probe data, a geopackage with the spatialized transects and a folder with a pdf showing the evolution of all the variables, accompanied by a text explaining the methodology and the meteorological parameters that influenced the measurements.
