title: Macroplastic ingestion in loggerhead turtles (Carretta caretta) stranded or bycaught in North Cyprus, eastern Mediterranean

description: Observations of investigations for plastic ingestion in loggerhead turtles (Caretta caretta), stranded or bycaught on the coastline of North Cyprus (Eastern Mediterranean). A total of 135 loggerhead turtles were sampled spanning a period of 11 years (2012-2022). During necropsy, the entire gastrointestinal tract was removed and initial contents weighed. The contents were grossly examined then rinsed through a 1 mm mesh sieve to separate and remove the plastic for classification and dietary items for storage and analysis. Ingested plastic was classified using a system outlined in Duncan et al. (2019, doi:10.1038/s41598-019-48086-4; 2021, doi:10.3389/fmars.2021.699521) which builds upon the Fulmar Protocol and MSFD (Marine Strategy Framework Directive) Marine Litter Report 2011 (Descriptor 10) toolkits (Galgani et al., 2014, doi:10.1016/j.marenvres.2014.02.003; van Franeker et al., 2011, doi:10.1016/j.envpol.2011.06.008).
description: Types of plastic (She, Thr, Foam, Frag, Poth, Ind): The type of plastic debris: Industrial plastic pellets or nurdles (IND) and user plastics (USE) which can be split into several sub-categories; sheetlike plastic (SHE e.g., plastic bags), threadlike/filamentous plastic (THR e.g., remains of rope), foamed plastics (FOAM e.g., polystyrene), fragments (FRAG e.g., hard plastic pieces) and other (POTH, e.g., rubber, elastics, items that are 'plastic-like', not clearly fitting into another category). Taken from Fulmar Protocol and MSFD (Marine Strategy Framework Directive) Marine Litter Report 2011 (Descriptor 10) toolkits. Counts observed in specific individual turtle. Colours of plastic: (Clear, White, Pink/Purple, Red, Orange, Yellow, Green, Blue, Bown, Black, Grey) Colour was recorded within 11 categories. Counts observed in specific individual turtle.

title: Swordfish bycatch data from tuna traps located at four sites in Italy, 1896-2010

description: The data set contains swordfish (Xiphias gladius) bycatches from artisanal bluefin tuna fishing traps located at four sites in Italy. Data records include the locations and dates for the catches and the catch in numbers and/or weight on given days during 1896-2010.The data have been recovered to increase understanding of the long-term dynamics of the population and its fisheries, including effects of exploitation and climate variability and change, and to provide baseline knowledge against which future variations can be compared. There are presently few other similarly long data sets for this species in this region. The data have been recovered from historical records, reports and archives associated with the traps.
description: Corresponding authors: Teresa Romeo (teresa.romeo@szn.it) and Brian R. MacKenzie (brm@aqua.dtu.dk)The project was supported by the participating institutes. An initial travel grant (Short Term Scientific Mission) was provided to BRM from the EU COST Action IS1403 (Oceans Past Platform: OPP) to visit colleagues (TR, PB, PC, FA) at Milazzo, Italy to discuss and plan project objectives and data recovery.The trap locations Favignana and Formica are close (ca. 10 km) to each other. The data for these two sites were only available as a combined sum for the 1970s and for a few single daily observations in other years. In years when only combined catch data from both traps were available, the event code is listed as "FavignanaFormica" and spatial coordinates are a simple average of latitudes and longitudes for the two individual sites. Similarly, the minimum and maximum depth of the rooms of the trap are averages of the minima and maxima.

title: Duration of a flood along a plant diversity gradient in the Jena Experiment (Main Experiment, June 2013)

description: The Jena Biodiversity Experiment is located on a Central European mesophilic floodplain on the banks of the Saale River (see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown in the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, or 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In June 2013, a natural 200-year flood event occurred at the field site. Rainfall in May 2013 in Jena was ~150mm, constituting &gt;25% of annual precipitation at the site that year. Overall the flood affected the entire Elbe River Basin and much of Europe and was one of the largest natural flooding events in the past two centuries. The flood lasted for a total of 24 days at the site (30 May–24 June) and led to anaerobic soil conditions. Due to small topographical differences among the plots in the experiment (&lt;1m), there was variation in the duration of flooding and the proportion of each plot that was flooded. This variation was well-distributed across the diversity gradient. To assess the importance of flood severity, the proportion of each plot that was flooded was estimated by eye (using five classes: 0 completely dry, 0.25 up to a quarter under water, 0.5 half, 0.75 up to three quarters under water, and 1 more than three quarters under water up to completely submerged). These values, for each of the 24 days that the flood lasted, were summed up to calculate a flooding index. The resulting flooding index is given for each plot of the Main Experiment.
description: This dataset is part of a collection of measurements on environmental conditions at the field site of the Jena Experiment. Data for other abiotic measurements, from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (doi:10.1594/PANGAEA.865134).

title: Monthly succession of marine biofouling communities in the Arabian Gulf

description: This study was undertaken as part of a collaborative project titled Biotechnological Applications of Marine Biofilms developing on solid surfaces in the Arabian Gulf funded by research grant (SQU-GCC/CL/17/02). The succession of marine biofouling communities (mature biofilms) on plastic panels were investigated over a period of six months in four locations in the Arabian Gulf (Fintas and Salmiya marinas in Kuwait, and Bandar Rowdha and Al Mouj marinas in Oman). Monthly assessment of the physico-chemical parameters of the seawater at each location was done using portable meters (thermometer, refractometer, pH meter, turbidity meter and conductivity/TDS meter). The concentrations of nutrients and elements were analysed using ion chromatography (IC) and inductively coupled plasma optical emission spectrometry (ICP-OES), respectively. After each month, the developed biofilm on each panel was quantitatively and qualitatively analyzed as follows; total wet weight, abundance of bacteria using epifluorescence microscopy, chlorophyll a concentrations using spectrophotometry, percent coverage of macrofoulers, and presence or absence of signs of grazing based on visual observations and/or photodocumentation (using Image J software), which was also used to assess the presence/absence and dominance of macrofouling species. Additionally, the composition of the microbial community was investigated using 16S amplicon sequencing, resulting in supplementary data sets for bacterial community composition, predicted bacterial metabolic pathways (Bowman and Ducklow 2015, doi:10.1371/journal.pone.0135868), and presence/absence of microalgae based on their chloroplast 16S.

title: Natural abundance of stable isotopes in micronekton fish species from the BATHYPELAGIC cruise (North Atlantic, June 2018): carbon and nitrogen values in bulk tissues and nitrogen values in amino acids

description: The values of natural abundance of stable isotopes were measured in 13 micronekton fish species sampled during the BATHYPELAGIC cruise (North Atlantic, June 2018). This dataset contains the values obtained for carbon and nitrogen in bulk tissues, and nitrogen values in amino acids. Length and biomass data for each individual analyzed are also provided. Fishes were collected using a ''Mesopelagos” net (5x7 m mouth opening, 58 m total lenght) equipped with graded-mesh netting (starting with 30 mm and ending with 4 mm) and a multi-sampler for collecting samples from 5 different depth layers (Olivar et al., 2017). Individual fish were eviscerated, freeze-dried and weighted. Aliquots of muscular tissue (or whole individuals for species of small size) were analyzed in an elemental analyzer (bulk tissues, Olivar et al., 2019) or a gas chromatograph (derivatized amino acids, Mompeán et al., 2016) coupled to isotope-ratio mass spectrometers. Carbon analyses were made before and after removal of lipids with a mixture of trichloromethane:methanol:water.

title: Diversity and abundance of deep-pelagic fish on the Bay of Biscay slope (North-East Atlantic) from 56 trawls hauls between 2002 and 2019

description: The dataset represents the number, the total and the standardized biomass (catch per unit effort) of 94 deep-pelagic fish species collected by pelagic trawling in submarine canyons of the Bay of Biscay slope during the EVHOE scientific cruises on R/V Thalassa in autumn between 2002 and 2019 (https://doi.org/10.18142/8). Fifty-six trawls were conducted at night between 20 m and 2000 m depth. The trawl net was 192 m long with a headline of 76 m and a foot rope of 70 m. The average vertical mean mouth opening was about 24 m and the horizontal opening of about 58 m. The mesh size gradually decreases from very large 8 m meshes at the mouth to 20 mm meshes in the codend. To allow the capture of very small specimens, the trawl is also equipped with a 7.5 m long sock with a 12 mm mesh. The trawl had an average vertical mouth opening of 24 m and a horizontal opening of 58 m. The duration of the haul was 1 hour at 4 kn. The trawl did not have an opening-closing mechanism. Therefore, some individuals might have been caught during the descent and ascent of the gear, however a higher trawl speed on deployment and a low speed on retrieval were implemented to reduce bycatch at shallower depths than the target depth. The biomass per unit effort is standardized by the volume hauled and was calculated by multiplying the vertical and horizontal trawl opening and the distance trawled. Individuals were identified by expert ichthyologists to the species level whenever possible, otherwise they were identified to the genus or family level, especially when individuals were too small or damaged. Species or taxa were counted and most often weighed. When weighing was not possible, an estimate of the average weight of individuals over the whole time series was calculated and the total weight per species was estimated.

title: Holocene diatom oxygen isotope record from Lake Khamra, Yakutia, Siberia

description: The dataset includes diatom oxygen isotope data of 22 samples from the sediment core EN20001, Lake Khamra, covering the Holocene. Contamination assessment, conducted on purified lake sediment samples, was performed by Energy-Dispersive X-ray Spectroscopy (EDS) measurements, carried out by a JEOL M-IT500HR analytical scanning electron microscope (SEM) with an integrated EDS-system supplied with a Peltier-element-cooled detector (SDD) at AWI Potsdam. The standardless procedure was used according to Chapligin et al. (2012), performing six repetitions with an acceleration voltage of 20.0 kV, magnification of 300 and a measuring time of 30 seconds. All detectable elements are given as oxides, with weight percentages (in %) and summed up to the total sum (total %) of each sample. The diatom oxygen isotope data was generated in the ISOLAB Facility at AWI Potsdam with a semi-automated laserfluorination line (Chapligin et al., 2010) in combination with a SERCON HS2022 mass spectrometer (https://hdl.handle.net/10013/sensor.4880f572-3c55-4e3e-a2e7-485d9bfa06b2). All δ18Odiatom values are given in per mill (‰) vs. Vienna Standard Mean Ocean Water (VSMOW). The dataset includes the mean of measured δ18Odiatom values (Diatom δ18O mean), its standard deviation (Diatom δ18O std dev) and number of replicates (Repl), as well as the calculated contamination (Contamination in %) and the δ18Odiatom corrected for contamination (Diatom δ18O corr).
