Aerobic respiration and hypoxia in the Lower St. Lawrence Estuary: Stableisotope ratios of dissolved oxygen constrain oxygen sink partitioning
Aerobic respiration and hypoxia Lawrence Estuary dissolved oxygen constrain oxygen sink partitioning
2014/4/17
We measured the concentration and the stable isotope ratios of dissolved oxygen in the water column in the Estuary and Gulf of St. Lawrence to determine the relative importance of pelagic and benthic ...

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...
Simulations of climate effects on water temperature, dissolved oxygen, and ice and snow covers in lakes of the contiguous U.S. under past and future climate scenarios
Simulations of climate effects on water temperature, dissolved oxygen, and ice and snow covers in lakes of the contiguous U.S. under past and future climate scenarios
2014/4/17
Daily water temperature, dissolved oxygen (DO) profiles, and ice and snow covers (where applicable) were simulated for 27 types of small lakes (up to 10 km2 surface area) at 209 locations in the conti...
Coupling of surface pCO2 and dissolved oxygen in the northern South China Sea:impacts of contrasting coastal processes
surface pCO2 dissolved oxygen South China Sea coastal processes
2010/1/21
We examined the relationship between CO2 partial pressure (pCO2) and dissolved oxygen (DO) based on a cruise conducted in July 2004 to the northern South China Sea (111°–118° E 18°–23° N), spanning fr...
Relationship between dissolved oxygen concentration of bottom water and macrophyte biomass in the southern basin of Lake Biwa, Japan
dissolved oxygen submerged macrophyte southern basin of Lake Biwa
2009/4/2
The horizontal distribution of dissolved oxygen (DO) concentrations on the lake bottom was investigated on September 2-5, 2002. At 36 out of the 84 sites, DO concentrations were at less than 50% of sa...
Dissolved oxygen transfer to sediments by sweep and eject motions in aquatic environments
Dissolved oxygen transfer sediments sweep eject motions aquatic environments
2014/4/21
Dissolved oxygen (DO) concentrations were quantified near the sediment–water interface to evaluate DO transfer to sediments in a laboratory recirculating flume and open channel under varying fluid-flo...
Dissolved oxygen response to wind–inflow interactions in a stratified reservoir
Dissolved oxygen response wind–inflow interactions
2014/4/22
Results of a field campaign and numerical simulations are used to show how physical mechanisms impose
length scales and timescales that determine the dominant biogeochemical process. As an example, t...
Universal scaling of dissolved oxygen distribution at the sediment-water interface: A power law
Universal scaling dissolved oxygen distribution the sediment-water interface A power law
2014/5/13
Dissolved oxygen (DO) distribution at the sediment-water interface of a flow over a smooth bed is investigated for Reynolds numbers >360 and <4,090. These conditions are commonly encountered in stream...

macrobenthos sand-pit lake temperature dissolved oxygen and community structure
2010/3/30
Water temperature (°C), pH, dissolved oxygen concentration (mg/l) and the community structure of the macrobenthos of a small southeast Texas sand-pit (Barry's) lake were studied from June 1995 to Febr...
