Offshore platforms: Comparison of five benthic indicators for assessing the macrozoobenthic stress levels
Within the European Water Framework Directive, many studies have been conducted to evaluate the sensitivity/robustness of a variety of indices in relation to natural or anthropogenic disturbance events. However, these indices have rarely been applied to verify the impacts of disturbances in offshore environments, though the Marine Strategy Framework Directive recommends their use for assessing benthic community conditions and functionality.
Haplotype diversity in the mtDNA cyt b gene in round goby (Neogobius melanostomus (Pallas)) from the northwestern part of the Black Sea basin
To study the genetic causes of successful biological invasion, haplotype diversity in the mtDNA cyt b locus was examined in populations of the round goby Neogobius malanostomus (Pallas): (Gobidae, Piscs) from the Black Sea basin, which is considered to be the main source of irruption. It was demonstrated that the haplotype diversity of this species was much higher than was assessed earlier. At the population level, a statistically significant association of haplotype diversity with the individual variation of plastic characters was established.
Fisheries statistics provided by the Hellenic Statistical Authority (HELSTAT) have been often criticized for unusual estimates in landings and fishing effort data and for limitations in the sampling methodology, although there is no study on the identification of these biased and misreporting estimates. In the present study the landings per species and fishing subarea, as well as the fishing effort data per fishing gear reported by HELSTAT were analysed over the period 1982–2010.
The Mediterranean Sea is considered a “hot-spot” for climate change, being characterized by oligotrophic to ultra-oligotrophic waters and rapidly changing carbonate chemistry. Coccolithophores are considered a dominant phytoplankton group in these waters. As a marine calcifying organism they are expected to respond to the ongoing changes in seawater CO2 systems parameters. However, very few studies have covered the entire Mediterranean physiochemical gradients from the Strait of Gibraltar to the Eastern Mediterranean Levantine Basin.
RAMS-forecasts comparison of typical summer atmospheric conditions over the Western Mediterranean coast
The Regional Atmospheric Modeling System (RAMS) has been used in order to perform a high-resolution numerical simulation of two meteorological events related to the most common atmospheric environments during the summer over the Western Mediterranean coast: mesoscale circulations and western synoptic advections. In this regard, we take advantage of the operational RAMS configuration running within the real-time forecasting system environment already implemented over this Mediterranean area, precisely in the Valencia Region and nearby areas.
GC–ITMS analysis of PAH contamination levels in the marine sea urchin Paracentrotus lividus in Sardinia
This paper describes the results of a two-year monitoring study examining the pollution of the sea urchinParacentrotus lividus by polycyclic aromatic hydrocarbons (PAHs) in Sardinia. GC–ITMS analysis of sea urchin gonads showed the presence of 11 and 12 PAHs in the samples of Capo Pecora, and Capitana, respectively. Fluorene, naphthalene and its two degradation products, 1-methyl-naphthalene, and 2-methyl-naphthalene, were detected in all samples analyzed.
Characterization of a Potential CO2 Storage Site in a Carbonate Aquifer – Example From the South Adriatic Offshore
The Southern Adriatic Sea is one of the five perspective areas for CO2 storage being evaluated under the FP7 European SiteChar project. This site is the most challenging among those studied in this project, since the potential reservoir is hosted in a carbonate formation. In a first instance, the 3D geological static model at both regional and local scale, was constructed, based on the analysis and the interpretation of the available geological, geophysical and borehole data.
