Documented sightings of harbour porpoises in the Mediterranean are rare, although the species is common in the neighbouring North Atlantic and Black Sea. However, in the past 2 decades, 4 harbour porpoises Phocoena phocoena have been recorded in the northern Aegean Sea in the eastern Mediterranean Basin. Samples were taken from 2 of these. Both have a genetic signature indicative of the Black S...

The Philippine Sea plate subducts beneath the Eurasia at Nankai Trough, northwestern Pacific, causing crustal deformation, mega-thrust earthquakes, and tsunami events. Shikoku Island, 150 km northwest of trough, experiences both coseismic interseismic deformation. Coastal sediments potentially record vertical movements as relative sea level (RSL) changes. We studied sedimentary facies microfoss...

Numerous planktonic species have disjunct distribution patterns in the world's oceans. However, it is unclear whether these are truly unconnected by gene flow, or whether they are composed of morphologically cryptic species. The marine planktonic chaetognath Sagitta setosa Müller has a discontinuous geographic distribution over the continental shelf in the northeastern Atlantic, Mediterranean S...

abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...

The ctenophore Bolinopsis vitrea is first reported from the Turkish and Bulgarian regions of the Black Sea. In Turkish waters, a considerable aggregation was found in Sile on the Asian side and at Kilyos on the European side in 2007. This appears to be the first record of this species in the Black Sea, which is known in the Mediterranean Sea including the Aegean Sea. Bolinopsis vitrea most like...

Concentration and electrophoretic properties of blood serum albumin of the round goby Neogobius melanostomus caught in Black Sea and Azov Sea were studied in relation to age, sex, maturation stage and season. Electrophoretic mobility of serum albumin in Black Sea fish increased with age, while in Azov Sea goby it varied less. No differences were observed in albumin characteristics between femal...

The lucrative and highly migratory Atlantic bluefin tuna, Thunnus thynnus (Linnaeus 1758; Scombridae), used to be distributed widely throughout the north Atlantic Ocean, Mediterranean Sea and Black Sea. Its migrations have supported sustainable fisheries and impacted local cultures since antiquity, but its biogeographic range has contracted since the 1950s. Most recently, the species disappeare...

The aim of this paper is to provide a survey on results and future perspectives of the project “Development an validation of a sea surface fractal model” approved by ESA in the framework of the “Opportunity of exploiting ENVISAT data”. The goal is to validate a sea surface fractal model, developed by the University of Pisa, trough the use of sea SAR images. New image fractal analysis techniques...

The relationships between total mercury (Hg) concentration and stable nitrogen isotope ratio (delta(15)N) were evaluated in Mullus barbatus barbatus and M. surmuletus from the Mediterranean Sea and M. barbatus ponticus from the Black Sea. Mercury concentration in fish muscle was six times higher in the two Mediterranean species than in the Black Sea one for similar sized animals. A positive cor...
