Road salts threatening world freshwater supplies
2021/4/23
When winter storms threaten to make travel dangerous, people often turn to salt, spreading it liberally over highways, streets and sidewalks to melt snow and ice.However, a new study led by Sujay Kaus...
The Temporal Variability of the Freshwater Discharge and Water Levels at the Patos Lagoon, Brazil
Freshwater Discharge El Niñ o La Niñ a Wavelet Analyzes
2013/3/11
The direct influence of freshwater discharge along the coastal regions is observed in several processes following a wide spectrum on spatial and temporal variability. The knowledge of relative importa...
A macro-tidal freshwater ecosystem recovering from hypereutrophication: the Schelde case study
A macro-tidal freshwater ecosystem hypereutrophication the Schelde case study
2010/1/21
We report a 40 year record of eutrophication and hypoxia on an estuarine ecosystem and its recovery from hypereutrophication. After decades of high inorganic nutrient concentrations and recurring anox...
Taphonomy of freshwater molluscs in carbonate-poor deposits:a case study of the river pearl mussel in northeastern Finnish Lapland
Conservational palaeobiology Bivalvia Margaritifera preservation shell periostracum
2009/12/2
The river pearl mussel, Margaritifera margaritifera, is becoming an important tool in reconstructing past changes in climate because of its shell growth increments and longevity. Surveys of the Lutto ...

Calcium carbonate saturation surface water Arctic Ocean freshwater influenced shelves
2010/1/21
In the summer of 2005, we sampled surface water and measured pH and total alkalinity (AT) underway aboard IB Oden along the Northwest Passage from Cape Farewell (South Greenland) to the Chukchi Sea. W...
Different carbon isotope fractionation patterns during the development of phototrophic freshwater and marine biofilms
carbon isotope fractionation patterns phototrophic freshwater marine biofilms
2010/1/14
Natural phototrophic biofilms are influenced by a broad array of abiotic and biotic factors and vary over temporal and spatial scales. Different developmental stages can be distinguished and growth ra...
Nitrogen assimilation and short term retention in a nutrient-rich tidal freshwater marsh – a whole ecosystem 15N enrichment study
Nitrogen assimilation short term retention nutrient-rich tidal freshwater marsh
2010/1/14
An intact tidal freshwater marsh system (3477 m2) was labelled by adding 15N-ammonium as a tracer to the flood water inundating the ecosystem. The appearance and retention of 15N-label in different ma...
