Climate impact on long-term changeability of the black sea bioluminescence field and plankton community characteristics. IBSS Repository
Tokarev, Yu.; Mel'nikov, V.; Burmistrova, N.; Belokopytov, V.; Temnykh, A..
Researches in the bioluminescence field vertical structure, amplitude characteristics and spatial distribution in the Black Sea have been conducted in IBSS, NAS of Ukraine, from up to the present time. Enough evidencies are available to testify dramatic changes in different Black sea ecosystem components including bioluminescence field parameters, which took place last decades. But still there is no direct answer to the question about the reasons for such transformations, as variability of the Black Sea biophysical (bioluminescence) and biological characteristics at the climatic time scales, i.e. at the scale of decade periods are not sufficiently studied now. The most pronounced changes in vertical structure of the bioluminescence field are observed in...

Modelling subsurface dynamics in the Black Sea ArchiMer
Karakas, G; James, Alec; Al-barakati, A.
Dependency of major hydrophysical/chemical features of highly stratified basins on density surfaces in the vertical makes isopycnic models an attractive tool for simulating the dynamics of marginal marine environments such as the Black Sea because of the ability of these models to restrict vertical transport to some desirable degree. In the present work the seasonal variations of the subsurface dynamics of the Black Sea are investigated using an isopycnic model. Particular attention is given to the interfaces of the Cold inter-mediate layer and Suboxic layer and finally, the deep layer circulation in the basin is studied. It appears that although the depth range of the base of the Cold intermediate layer and the lower Soboxic layer interface do not change...
