The Mediterranean monk seal Monachus monachus (Hermann, 1779) is one of the critically endangered species in the world and in the northeast Mediterranean Sea there is a continuously breeding population. On 28 February 2014, 3-3.5 months old, male Mediterranean monk seal stranded near Yasilovacık Harbour, Mersin. Gross necropsy was carried out one day later. The seal was emaciated and lungs were pneumonic. This paper summarizes the preliminary findings of the gross necropsy.

Hydrozoan Geryonia proboscidalis (Forskål, 1775) was observed in July 2012 in Iskenderun Bay (Samandag), for the first time in the northeastern Mediterranean coast of Turkey. The presence of G. proboscidalis in the northeastern Mediterranean coast of Turkey may be due to transportation via ballast waters of ship or water currents.

First occurrence of Serranus hepatus in the Bulgarian Black Sea coast
Institute of Biodiversity and Ecosystem Research, Bulgarian Academy of Sciences, 2 Gagarin Street, 1113 Sofia, BULGARIA
The brown comber (Serranus hepatus) is a common representative of the Mediterranean fish fauna. Recently it had been reported for the first time in the Black Sea, near the Istanbul Strait (Bosphorus). Two additional specimens were registered in the southern Bulgarian Black Sea sector; one of them was measured and reported here, in order to establish some basic morphometric traits.

The presence and distribution of the 16 polycyclic aromatic hydrocarbons (PAHs) priority pollutant listed by US EPA (Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo[a]anthracene, Chrysene, Benzo[b]fluoranthene, Benzo[k]fluoranthene, Benzo[a]pyrene, Dibenzo[a,h]anthracene, Benzo[g,h,i]perylene, Indeno[1,2,3-c,d]pyrene) were investigated in sediments from 35 stations of the Ligurian coast (Northern Italy). Results were shown as total PAH concentrations (PAHs) and molecular indices based on ratios of selected PAH concentrations were used to differentiate PAHs from pyrogenic and petrogenic origin. Analysis was performed by gas/chromatography mass spectrometry (GC/MS) with selected ion monitoring (SIM). Total PAHs concentrations ranged from 1113 to 17006 ng/g of dry matrix. PAH profiles varied according to the nature of the site and its proximity to sources; in general, the contamination levels of total PAHs were similar to those observed in contaminated and slightly contaminated sediments of the Mediterranean Sea. In some cases the concentration of contaminants is influenced by physical circulation processes that raise the concentrations of anthropogenic pollutants offshore an order of magnitude higher than those near industrial and harbors activities.

Science in Antarctica and the role of the Scientific Committee on Antarctic Research (SCAR)

Scientific research in Antarctica requires international cooperation due to the magnitude of the objectives, the particular conditions of the Antarctic environment, and also because the Antarctic Treaty, signed in 1959 and entered into force in 1961, recognizes scientific research and international cooperation as important pillars. The Scientific Committee on Antarctic Research (SCAR), established in 1958, is the organisation responsible for promoting and coordinating scientific research in the Antarctic region (including the Southern Ocean) and for providing scientific advice to the Antarctic Treaty System and to other international bodies on Antarctica. This paper illustrates how SCAR operates to accomplish its mission and how it is organized to develop and coordinate the researches carried out by a large scientific community belonging to the – as of 2013 – 37 SCAR member countries. The five SCAR Scientific Research Programmes initiated in 2013 are a framework that will orientate a significant part of the research efforts during the next four to eight years. These programmes are highlighted in this paper, as well as other initiatives currently carried out by SCAR.

In this work phthalates pollution in red, brown and green algae in the Black Sea, Istanbul Starait and Çanakkale Strait were investigated. The detected phthalate derivatives were DEP, DIBP, DBP and DEHP. Very toxic phthalate DEHP was found only in the Istanbul Strait. Phthalates pollution of algae depends on the pollution of sea water.

The significant increase of the world population in recent years has encouraged researches to focus on the utilization of marine food resources together with the terrestrial ones for human consumption. Being an important source of protein and an effective source used not only as fertilizer but also in the industry with its useful chemical content makes Ulva rigida C.Agardh a target topic for research. In present study, seasonal and locational changes of the chemical compositions of U. rigida were investigated. The analyses were carried out in duplicate and seasonally (fall, winter, spring and summer). Significant differences were recorded in the findings obtained for the species collected in terms of seasons and stations.

Quantitative determination of fucoxanthin was made in the ontogenetic series of 1st order branches of the brown alga Cystoseira barbata (Stackh.) C. Agardh growing in upper sublittoral zone of Martyn Bay (Black Sea coast of Crimea). The greatest content (3 mg/g dry mass) was characteristic of the branches 2 – 3 months old. Total amount of this carotenoid which natural Cystoseira can hold is evaluated from 508 to 1810 mg per square meter of the sea bed.

Free-living marine nematodes inhabiting the shallow waters (3m) of Sinop Bay were analyzed to evaluate their usage as biological indicators. Their functional diversity was studied seasonally (August 2009, October 2009, January 2010 and April 2010). Life history strategies (c─p scaling) of nematode assemblages were examined. The Maturity Index (MI) based on c─p scale was calculated to test if it may be used for the interpretation of the environmental conditions and the determination of the ecological quality status of benthic habitats in the Black Sea ecosystem. Highest MI value was found at station C1 in April where the lowest organic matter concentration was recorded. The results indicated a possible utilization of MI and c–p class percentages to identify the ecological quality status of benthic environments according to Water Framework Directive.
