SULFUR GAS OF VOLCANIC ERUPTIONS AS A PROBABLE CAUSE OF ALTERATIONS AND CRISES IN THE MESOZOIC ECOSYSTEMS (Papers SGEM2018)

O. N. Zlobina, E. A. Predtechenskaya, A. A. Zlobin
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The role of sulfur gas of intense volcanic exhalations is considered as an important source of sulfur in sedimentation basins and as a probable cause of alterations and crises in the Mesozoic ecosystems. In the work sedimentary deposits of different ages and genesis are analyzed, (...)


THEORETICAL AND EXPERIMENTAL STUDY OF TURBULENT GAS FLOW THROUGH A PNEUMATIC MECHANISM (Papers SGEM2018)

T. Stanciu, A. Constantin
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The pressure regulators used in underwater breathing apparatuses determine the respiratory comfort of the diver. Our study focuses on the turbulent flow of gas through the series of valves and nozzles that are component elements of a pressure regulator. The pneumatic resistance, (...)


A CONCEPT OF A MODEL FOR THE MANAGEMENT OF SHIP-GENERATED WASTE AND CARGO RESIDUES IN A PORT AREA (Papers SGEM2018)

A. Deja, P. Kabulak, M. Kaup
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This paper presents the problems of ship-generated waste management in port areas. The first part contains a classification and characterisation of ship-generated pollution, with a particular focus on waste and cargo residues. Further to that, the legal and documentation aspects of (...)


ANALYSIS OF THE EXTREME EVENTS REPORTED IN THE PROXIMITY OF THE ROMANIAN HARBOUR AREAS (Papers SGEM2018)

V. Rata, Rusu, C. Gasparotti
Thursday 11 October 2018 by Libadmin2018
ABSTRACT From the perspective of the global climate changes, the aim of this paper is to analyse the extreme events that have taken place near the Romanian harbors in the last 30 years. In order to identify these extreme events, the hindcast data simulated by a wave modelling system (...)


ANALYSIS OF WASTE COLLECTED FROM PASSENGER-CARGO FERRIES AT THE PORT OF SWINOUJSCIE (Papers SGEM2018)

A. Deja, P. Kabulak, M. Kaup
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This paper presents the analysis of quantities and types of waste delivered to port reception facilities by passenger-cargo ferries at the Port of Świnoujście. The waste classification set out by applicable legal provisions, statistics on the numbers and sizes of vessels delivering (...)


BIOPHYSICAL AND BIOCHEMICAL METHODS AT THE COASTAL ZONE MONITORING (Papers SGEM2018)

E. Skuratovskaya, O. Mashukova, I. Sysoeva, O. Danilova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The examples of modern biophysical and biochemical methods used at the Black Sea coastal zone biotesting were presented. Their obvious advantages in precision, objectivity and efficiency of received information in comparison with other methods were shown. The bioluminescence analysis (...)


COMPARATIVE UV-VIS SPECTRAL STUDIES ON CHITOSAN FROM DIFFERENT MARINE ORGANISMS (Papers SGEM2018)

C. Paduretu, M. R. Apetroaei, S. I. Damian, M. G. Apetroaei, V. Schroder
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Chitosan is a natural polymer very widespread in the animal world, particularly in marine organisms. This biopolymer has three reactive groups in each glycoside unit of the polymeric chain: an amino group and two hydroxyl groups, which determine its characteristics. Between these (...)


DISTRIBUTION OF RADIOCAESIUM IN ARCTIC MARINE SEDIMENTS (Papers SGEM2018)

D. Alexeev, V. Shelutko, E. Mikhteeva, L. Dmitricheva
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The purpose of this research study is to identify the characteristics of marine sediments, which determine the accumulation of different radionuclides as a result of statistical analyses. The main attention is paid to the accumulation of radionuclides from the data on grain size and (...)


DISTRIBUTION OF THE ZOOPLANKTON ECOLOGICAL COMPLEXES IN THE EASTERN PART OF THE GULF OF FINLAND OF THE BALTIC SEA (Papers SGEM2018)

N. Silina, E. Kunaeva, M. Lebedeva
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The Gulf of Finland belongs to the large bays of the Baltic Sea. The eastern part of the Gulf of Finland is an estuary of the Neva River. The heterogeneity of its water masses is typical for the eastern part of the bay. The main reason of such issue is the significant spatial (...)


ECOSYSTEMS OF SUBARCTIC SEAS OF RUSSIA AS A LARGE RESERVOIR OF THE RUNOFF AND DEPOSITION OF ATMOSPHERIC CARBON (Papers SGEM2018)

E. Shirkova, E. Shirkov, V. Masnev
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Currently a sharp increase of carbon dioxide content in atmosphere of the Earth is one of the great environmental concerns. It could lead to negative (possibly catastrophic) changes of our planet climate. Experts attribute the rapid and significant increase in anthropogenic CO2 (...)
