Environmental change in Africa:Will it lead to a drying Lake Victoria?（图）
Environmental change Africa drying Lake Victoria
2019/11/21
Global climate change could cause Africa's Lake Victoria, the world's largest tropical lake and source of the Nile River, to dry up in the next 500 years, according to new NSF-funded findings by a tea...
How satellite data led to a breakthrough for Lake Erie toxic algal blooms
satellite data Lake Erie toxic algal blooms
2017/5/15
With the growing frequency and magnitude of toxic freshwater algal blooms becoming an increasingly worrisome public health concern, Carnegie scientists Jeff Ho and Anna Michalak, along with colleagues...
Coastal Sediment Dynamics and River Discharge as Key Factors Influencing Coastal Ecosystem Productivity in Southeastern Lake Michigan
Coastal Sediment Dynamics River Discharge Coastal Ecosystem Productivity Southeastern Lake Michigan
2015/7/22
A central question addressed by the Episodic Events in the Great Lakes Experiment (EEGLE) was the extent to which the spring phytoplankton bloom in southern Lake Michigan is influenced by a recurrent ...
Winter-Spring Storms and Their Influence on Sediment Resuspension,Transport,and Accumulation Patterns in Southern Lake Michigan
Winter-Spring Storms Sediment Resuspension Transport Accumulation Patterns Southern Lake Michigan
2015/7/22
The Episodic Events-Great Lakes Experiment was designed to quantify the impacts of major late winter-early spring storms on sediment-water exchange, sediment, and associated constituent transport and ...
Lake in a Bottle:A Laboratory Demonstration of the Unusual Stability Properties of Freshwater
Lake in a Bottle Unusual Stability Properties Freshwater
2015/7/13
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...
Each summer, Greenland’s ice sheet — the world’s second-largest expanse of ice, measuring three times the size of Texas — begins to melt. Pockets of melting ice form hundreds of large, “supraglacial” ...
Stable isotope estimates of evaporation : inflow and water residence time for lakes across the United States as a tool for national lake water quality assessments
inflow water residence
2014/11/28
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s
National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
Stratification and horizontal exchange in Lake Victoria, East Africa
Lake Victoria East Africa
2014/11/28
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...
A regime shift in Lake Superior ice cover, evaporation, and water temperature following the warm El Nin˜ o winter of 1997–1998
ice cover evaporation water temperature
2014/11/28
Significant trends in Lake Superior water temperature and ice cover have been observed in recent decades, and
these trends have typically been analyzed using standard linear regression techniques. Al...

Influence of bottom water anoxia on nitrogen isotopic ratios and amino acid contributions of recent sediments from small eutrophic Lonar Lake, central India
nitrogen isotopic ratios Influence
2014/4/2
Lonar Lake is a eutrophic, saline soda lake with permanently anoxic deep water. The high pH and
deoxygenation result in very elevated d15N of suspended particulate matter (SPM) and sediments due to
...
Anaerobic ammonium oxidation (anammox) bacteria and sulfide-dependent denitrifiers coexist in the water column of a meromictic south-alpine lake
Anaerobic ammonium oxidation bacteria sulfide-dependent denitrifiers coexist in the water column a meromictic south-alpine lake
2014/4/2
In addition to organotrophic denitrification, alternative pathways, such as anaerobic ammonium oxidation(anammox) or sulfide-dependent denitrification may be important modes for the removal of fixed n...
Using stable nitrogen isotopes to evaluate the relative importance of external and internal nitrogen loadings on phytoplankton production in a shallow eutrophic lake (Lake Mikata, Japan)
a shallow eutrophic lake phytoplankton production
2014/4/2
The seasonal variability of the stable nitrogen isotope (d15N) in phytoplankton and dissolved inorganic
nitrogen (DIN) in the shallow, eutrophic Lake Mikata was examined to assess the relative import...
Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.
lake districts of Alaska
2013/4/2
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of
climate change. In lake-rich regions, the loss of ice cover also plays a key role in landsca...
