Using simple laboratory gear, students can simulate the stratification properties of a freshwater lake and the impact of salt on the relationship between temperature and density. Because some students...
We characterize stratification patterns over diel, seasonal, and annual time scales in inshore and offshore regions of Lake Victoria, East Africa; determine conditions leading to horizontal exchanges;...
We analyzed complete geospatial data for the 3.5 million lakes and reservoirs larger than 0.001 km2, with a combined surface area of 131,000 km2, in the contiguous United States (excluding the Laurent...
Ultraviolet solar radiation (UVR) and atmospheric nutrient inputs associated with aerosols are major worldwide stressors that simultaneously affect species and the interaction among them. A 2 3 5 fie...
Pockmarks are well known in the marine environment but almost unreported from limnic systems. In Lake Constance we investigated pockmarks near the mouth of the main tributary, Alpine Rhine River, usi...
High-resolution thermistor chain data collected between 5 and 20 m in a large stratified freshwater lake (Lake Constance) at a water depth of 60 m reveal the frequent occurrence of large-amplitude ($...
Low dissolved oxygen during the summer and early fall controls profundal continental ostracode distribution in Crystal Lake (McHenry County), Illinois, favoring Cypria ophthalmica and Physocypria glo...
We studied three-dimensional distribution patterns of temperature, phyto- and zooplankton, and fish in the large, prealpine Lake Constance during spring 2007. A strong westerly wind induced an intens...
To assess the long-term (27 yr) effects of sediment aging on stable carbon and nitrogen isotope values (d13 C and d15N), we used a collection of eight freeze cores of annually laminated (varved) lak...
An iron-dependent cyanobacterial bioreporter (Synechococcus strain KAS101) was used in unison with sizefractionated iron content (.0.45, ,0.45, ,0.02 mm), and chemical characterization of iron complex...
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern Great Plains, but little is known of how the relative importance of these processes may vary...
We investigated the Ra isotope quartet in order to quantify the discharge of saline groundwater into a freshwater lake. The activities of 226Ra, 228Ra, 223Ra, and 224Ra were measured in the Sea of Ga...
In this study, we report on the ability of four one-dimensional lake models to simulate the water temperature profiles of Lake Geneva, the largest water body in Western Europe, over a 10-yr period fr...
The isotope composition of zinc (Zn) was determined in settling particles collected monthly over a year in the hypolimnion of the eutrophic Lake Greifen (Switzerland) in order to explore the potentia...
The effects of climatic variables on lake-water total organic carbon (TOC) concentrations and benthic and pelagic primary producers during the past 45 yr were assessed using the sediment records of t...
