    Description: The SESAME dataset contains mesozooplankton data collected during April 2008 in the North-Western part of Black Sea (between 44°46' N and 42°29'N latitude and 28°64'E and 30°59'E longitude). Mesozooplankton sampling was undertaken at 9 stations where samples were collected using a Hensen net in the 0-10, 10-25, 25-50, 50-100, 100-150, 150-200 m layer. The dataset includes 29 samples analysed for mesozooplankton species composition and abundance. The entire sample or an aliquot (1/2 to 1/4) was analyzed under the binocular microscope. Calculations of zooplankton abundance are made by the following formulae, in accordance with the Report of the third ICES/HELCOM workshop on quality assurance of Biological measurements Warnemünde, Germany, 1996. M - number of counted specimens (ind.), Vf - volume of filtrated water (m³), and K - counted part of sample. (http://www2008.io-warnemuende.de/research/helcom_zp/documents/qa_zp_part.pdf)

    Description: Hybrid operation of wind farms has been in the limelight in recent years wherein the stochastic nature of wind causes market operators to choose an optimal strategy to maximize profit. The current work deals with a multi-criteria decision making approach to choose the best possible alternatives for a hybrid wind farm operation. A set of three, non-beneficial criteria, namely wind wakes, wind curtailment, and forced outages, were chosen to evaluate the best alternative. Three methods, (i) Simple Additive Weighting (SAW), (ii) the Technique for Order or Preference by Similarity to Ideal Solution (TOPSIS) and (iii) Complex Proportional Assessment (COPRAS), were applied to identify the best alternative, and the results revealed that for all three methods, borrowing deficit power from a neighboring wind farm is the best alternative. Comparative analyses in terms of the data requirement, the effect of dynamic decision matrices, and rank reversal in wind farm application have also been pioneered.

    Description: Four exploration license areas for manganese nodules (German, Inter Ocean Metal, Belgian, and French) and one Area of Particular Environmental Interest, located within Clarion-Clipperton Fracture Zone (north-eastern tropical Pacific Ocean) were investigated in terms of CTD, nutrients and chlorophyll data during the SONNE 239 cruise carried out in March-April 2015. Chlorophyll measured either in the surface layer (concentrations within 0.05-0.15 mg·m-3) or subsurface chlorophyll maximum layer (concentrations within 0.23-0.45 mg·m-3) showed a quite low primary productivity, strongly influenced by the thermocline position. The shallow thermocline (75-90 m depth) observed in the southern edge of the studied area (≈11°N) led to a shallow and moderate subsurface chlorophyll maximum layer (50-60 m depth and concentrations within 0.4-0.45 mg·m-3). Northwards, at ≈18°N, the thermocline dropped down to 120 m depth, resulting in a deeper (110 m depth) and weaker subsurface chlorophyll maximum (concentration of 0.23 mg·m-3). The oxygen minimum layer, characteristic to the eastern Pacific Ocean, showed a spatial variability in the studied area in terms of the depth of occurrence and thickness. Thus, shallower (80-90 m depth) and thicker (thickness within 1000-1050 m) oxygen minimum zones were observed in the southernmost license areas as compared to the northernmost area (280 m depth and thickness of 750 m).
