Global carbon dioxide emissions from inland waters
Carbon dioxide (CO2) transfer from inland waters to the atmosphere, known as CO2 evasion, is a component of the global carbon cycle. Global estimates of CO2 evasion have been hampered, however, byExpand
Hypoxia in the Baltic Sea and basin-scale changes in phosphorus biogeochemistry.
Analysis of data from 1970 to 2000 at the basin scale shows that the estimated volume of water with oxygen was actually at a minimum at the end of the longest so-called stagnation period on record, and addresses the legacy of eutrophication on a basinwide scale. Expand
Second Assessment of Climate Change for the Baltic Sea Basin
BACC (BALTEX Assessment of Climate Change for the Baltic Sea Basin) integrates available knowledge of historical, current and expected future climate change. The unique feature of BACC is theExpand
Effect of Danube River dam on Black Sea biogeochemistry and ecosystem structure
Rivers contribute significantly to the pollution and eutrophication that have caused drastic changes to the ecosystem of the Black Sea1–3. Although damming is known to affect riverborne nutrientExpand
Long-term ecological changes in Romanian coastal Waters of the Black Sea
Measurements in the Sulina branch of the Danube reveal that there was a five- and two-fold increase, respectively, of the total inorganic nitrogen and phosphate loads of theDanube River, whereas the riverine input of silicate decreased to about one-third. Expand
Overview of eutrophication indicators to assess environmental status within the European Marine Strategy Framework Directive
In 2009, following approval of the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission (EC) created task groups to develop guidance for eleven quality descriptorsExpand
Nitrogen fluxes from the landscape are controlled by net anthropogenic nitrogen inputs and by climate
The flux of nitrogen (N) to coastal marine ecosystems is strongly correlated with the “net anthropogenic nitrogen inputs” (NANI) to the landscape across 154 watersheds, ranging in size from 16 km2 toExpand
Silicon Retention in River Basins: Far-reaching Effects on Biogeochemistry and Aquatic Food Webs in Coastal Marine Environments
Regulation of rivers by damming as well as eutrophication in river basins has substantially reduced dissolved silicon loads to the Black Sea and the Baltic Sea, resulting in changes in the nutrient composition of river discharges. Expand
Future changes in the Baltic Sea acid–base (pH) and oxygen balances
ABSTRACT Possible future changes in Baltic Sea acid–base (pH) and oxygen balances were studied using a catchment–sea coupled model system and numerical experiments based on meteorological andExpand
An extensive bloom of the N2-fixing cyanobacterium Trichodesmium erythraeum in the central Arabian Sea
A preliminary extrapolation based on observed, non-bloom rates of N, fixation from limited sampling in the spring intermonsoon suggest N2 fixation may account for an input of about 1 Tg N yr-I, which is substantial, but relatively minor compared to current estimates of the removal of N through denitrification in the basin.
