Tabacarie Lake – a model of urban pollution
Abstract. Tabacarie coastal lake has been surrounded, during the past century, by the fast developing city of Constanta. Consequently, the lake has directly suffered from human interventions, such as dredging, embankments and heavy pollution. The lake surface sediments are generally fine grained: clayey silts and silts, with sands appearing only on dredged bottoms. The review of the chemical composition of upper sediments pointed out the presence of large quantities of certain heavy metals, in particular: Zn, Ba, Cu and Pb, dispersed, mainly, near the discharge points of rainwater pipes
Contribution to the Knowledge of Recent Ostracod Fauna from Some Danube Delta Lakes
The limnic ostracod fauna from some Danube Delta lakes was investigated. Eighteen species were recorded, and a brief description including information on the ecology and the geographical distribution of the main species was provided. Cypria ophthalmica was the most frequent and abundant species, followed closely by Darwinula stevensoni. A brackish water assemblage, represented by Cyprideis littoralis, Tyrrhenocythere amnicola donetziensis and Cytheromorpha fuscata was identified only in the Razelm-Sinoe lagoon
Abundance and biomass of meiobenthos in the Black Sea during Mare Nigrum cruise S-RO1
Dataset containing meiobenthos data for samples collected during the September 2008 Sesame Cruise in the North-West Black Sea on board of the Romanian R/V Mare Nigrum. Meiobenthos samples were collected in 5 stations, using a multicorer MARK II-400. The dataset includes 5 samples analysed for meiobenthos species composition, abundance and biomass.
The entire washed sample was analyzed under the binocular stereomicroscope. Meiobenthic species were identified and enumerated; some meiobenthic species were identified and enumerated only at higher taxonomic level. Taxonomic identification was done at GEOECOMAR
Biogeophysical, geophysical and geochemical research on the western Black Sea shelf.
Abstract. Expeditionary research along the western Black Sea shelf took place in 1990 within the International INTER-GEO-ECO-MONITORING Programme. The programme included continuous bathymetric recordings, measurements of the electromagnetic field and emissions of atmospheric Mercury, and biogeophysical applications. The high degree of correlation between the results of the four methods used, which are very different, considering the parameters examined, reveals the existence of a common denominator. Thus, the fault planes represent the transmission paths of some elements (like Mercury) from the Earth’s Mantle to the surface, generate anomalies in the electromagnetic field and induce biogeophysical anomalies reflected in the microrelief of the sea floor
