Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and...
A new study by National Science Foundation-funded researchers at the Woods Hole Oceanographic Institution and their colleagues found that freshwater runoff from rivers and continental s...
Salt is power. The energy in places where salty ocean water and freshwater mingle could provide a massive source of renewable power. Stanford University researchers have developed an affordable, durab...
Ray Schmitt's introduction to this issue underlines the importance of including the oceanic component of the hydrological cycle in considerations of Earth's climate. Spatial and temporal salinity vari...
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...
Irvine, Calif., Sept. 2, 2014 — Freshwater runoff from the Sierra Nevada may decrease by as much as one-quarter by 2100 due to climate warming on the high slopes, according to scientists at UC Irvine ...
The biochemical composition of dissolved organic matter (DOM) strongly influences its biogeochemical role in freshwater ecosystems, yet DOM composition measurements are not routinely incorporated int...
We tested the hypothesis that cladocerans with higher calcium (Ca) content are more susceptible to Ca limitation by conducting life table experiments using four cladoceran species with contrasting Ca ...
We examined the dispersal of larvae (glochidia) of a common unionid mussel species, Actinonaias ligamentina, which need to attach to a host fish in order to develop into juveniles, in a lowland river...
Molybdenum (Mo) is essential for the biological assimilation of inorganic nitrogen (N). We compared Mo requirements for N2 -fixation in two species of filamentous heterocystous cyanobacteria (HC) to...
Between February and October 2007, a time series of alkyl nitrate concentrations in the water column of a shallow freshwater lake, University of East Anglia Broad, located in southeastern England was ...
Green Bay, while representing only ~7% of the surface area and ~1.4% of the volume of Lake Michigan, contains one-third of the watershed of the lake, and receives approximately one-third of the total ...
We investigated the effect of food quality on somatic growth and reproduction of zooplankton at different temperatures (12uC, 15uC, 20uC, and 25uC). Standardized growth experiments of two cladocerans...
Chemical defenses have been hypothesized to be widespread among aquatic bacteria, but few studies have assessed the susceptibility of pelagic consumers to bacterial secondary metabolites. In this stu...
Green Bay, while representing only ,7% of the surface area and ,1.4% of the volume of Lake Michigan, contains one-third of the watershed of the lake, and receives approximately one-third of the total...
