"A lake is a landscape's most beautiful and expressive feature. It is Earth's eye; looking into which the beholder measures the depth of his own nature." ---Henry David Thoreau, Walden.Baikal, Biwa an...
In 2008 scientists from Woods Hole Oceanographic Institution (WHOI) and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack o...
Two Lakes Beneath the Ice in Greenland, Gone Within Weeks
Two Lakes Beneath the Ice Greenland Gone Within Weeks
2015/3/4
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly dr...
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...
Prediction of surface temperature in lakes with different morphology using air temperature
lakes air temperature
2014/11/28
Temperature of the surface layer of temperate lakes is reconstructed by means of a simplified model on the
basis of air temperature alone. The comparison between calculated and observed data shows a ...
Recent changes in production in oligotrophic Uinta Mountain lakes, Utah, identified using paleolimnology
oligotrophic Uinta Mountain lakes Utah
2014/11/28
We use multiple proxies from lake sediment records of six remote alpine lakes in the Uinta Mountains, Utah,
to investigate primary production and potential drivers of changes in trophic status over t...
Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes
The ecological system lakes

Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes。
Regional-scale variation of dissolved organic carbon concentrations in Swedish lakes
Organic carbon lakes
2014/10/16
We assessed spatial variability in dissolved organic carbon (DOC) concentrations measured in nearly 2000
Swedish lakes. Inter-lake variance peaked at two different scales, representing within-region ...

production in oligotrophic Mountain lakes Utah identified paleolimnology
2014/10/16
We use multiple proxies from lake sediment records of six remote alpine lakes in the Uinta Mountains, Utah, to investigate primary production and potential drivers of changes in trophic status over th...
Research shows declining levels of acidity in Sierra Nevada lakes
Sierra Nevada lakes declining levels
2014/9/12
RIVERSIDE, Calif. — California’s water supply depends on a clean snow pack and healthy mountain lakes. The lakes receive a large amount of runoff in the spring from the melting snowpack. If the snow...
Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
Phosphorus enrichment and carbon depletion contribute to high Microcystis biomass and microcystin concentrations in Ugandan lakes
Phosphorus enrichment carbon depletion contribute
2014/4/2
We investigated the factors influencing cyanobacterial biomass and microcystin (MC) concentrations in several
Ugandan lakes from September 2008 to February 2009. We characterized thermal structure, l...
Modeling wind waves and wave exposure of nearshore zones in medium-sized lakes
Modeling wind waves wave exposure nearshore zones medium-sized lakes
2014/4/2
We determine wind-wave properties and estimate the wave exposure along the entire shore of Lake U¨berlingen,a subbasin of Lake Constance, using a third-generation spectral wave model (SWAN), and compa...
Chemical diversity and spatial variability in myriad lakes in Nhecolaˆndia in the Pantanal wetlands of Brazil
Chemical diversity spatial variability Pantanal wetlands
2014/4/2
Nearly 15,000 shallow, saline or freshwater lakes and ponds coexist in close proximity in the Nhecolaˆndia, a
24,000 km2
subregion of the Pantanal wetland in Brazil. This study aims to understa...
Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
