Sea level rise causes devastating effects on coastal habitats. For example, coastal erosion and saltwater intrusion are major threats for the Black Sea coasts. So, determining sea level changes in the...

It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970). New geological data and the recognition of sudden population move...
The Black Sea is a deep (about 2 km) elliptic basin with zonal and meridional dimensions of approximately 1000 km and approximately 400 km, respectively, located roughly between 28° and 42°E longitude...
In this issue of Oceanography we have 10 papers that will introduce readers to the fascinating and exciting research that is being conducted in the Black Sea. I wrote my first Black Sea paper in 1973 ...
Determining the basic processes governing the biogeochemical structure of the water column is a key challenge for today's oceanographers. Knowledge of these basic processes for an aquatic system makes...
Nitrogen is an essential nutrient for living systems in the ocean; it is a component of proteins, chlorophyll, and nucleic acids. In the oceans, nitrogen exists as a dissolved gas (N2), dissolved orga...
The Black Sea is the world's largest marine anoxic basin. The Black Sea's water below a depth of ~100 m is enriched with hydrogen sulfide that formed after the intrusion of seawater as a result of sea...
The importance of the Black Sea extends far beyond its regional role as a mixing body where Mediterranean water is diluted. This sea's marine environment acts as a small-scale laboratory for investiga...
Gelatinous zooplankton are known to have a substantial effect on pelagic food webs by exerting top-down control on their ecosystems (Purcell and Decker, 2005), but their impact could be even greater w...
Uppermost Holocene (Unit 1) microlaminated sediments of the deep central Black Sea, which accumulate at ca. 0.02 cm/y, are a classic natural laboratory for exploring geochemical proxies used to identi...
The Black Sea, a nearly enclosed and isolated environment, has suffered from severe ecological changes during the last three decades. It has been converted from an oligotrophic (less than 100 grams of...
It was not until the late 1980s that the international community became aware of the magnitude of the ecological crisis underway in the Black Sea. Major components of the ecosystem had begun to collap...
Marine ecosystems respond to climate changes at all trophic levels, from primary producers to herbivores to higher predators, in terms of growth, life history traits, and population dynamics (Stensth ...
Between April 2007 and October 2008 we collected 1995 horse mackerel specimens from the territorial waters of the Bulgarian Black Sea. Age, length, and weight of these specimens were determined to est...
