Oxygen Concentrations and Biological Fluxes in the Open Ocean
Oxygen Concentrations Biological Fluxes Open Ocean
2015/7/17
The oxygen concentration in the ocean is controlled by a delicate balance between the source from atmosphere-ocean interaction and net respiration of organic matter after the water leaves the surface ...
Patterns and Controls of Nutrient Concentrations in a Southeastern United States Tidal Creek
Nutrient Concentrations Southeastern United States
2015/7/16
Terrestrial inputs largely govern nutrient delivery to the coastal ocean, and subsequent processes transform these nutrients in the land-ocean transition zone. Here, we describe spatial and temporal p...
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 ...
Thalassia testudinum phosphate uptake kinetics at low in situ concentrations using a 33 P radioisotope technique
Thalassia testudinum phosphate uptake situ concentrations
2014/4/23
A new 33
P-tracer technique was used to define low-level phosphate (Pi) uptake kinetics for a dominant tropical
seagrass, Thalassia testudinum. We established seagrass Pi uptake kinetics at hi...
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...
Increased intracellular concentrations of DMSP and DMSO in iron-limited oceanic phytoplankton Thalassiosira oceanica and Trichodesmium erythraeum
Increased intracellular DMSO Trichodesmium erythraeum
2014/4/2
We investigated the link between iron (Fe) limitation and intracellular dimethylsulfoniopropionate (DMSP)
concentration in two oceanic phytoplankton species, the diatom Thalassiosira oceanica and the...
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...
The effects of elevated carbon dioxide concentrations on the metamorphosis, size, and survival of larval hard clams (Mercenaria mercenaria), bay scallops (Argopecten irradians), and Eastern oysters (Crassostrea virginica)
elevated carbon dioxide concentrations the metamorphosis size survival of larval hard clams bay scallops Eastern oysters
2014/4/17
We present experiments that examined the metamorphosis, growth, and survivorship of larvae from three species of commercially and ecologically valuable shellfish (Mercenaria mercenaria, Argopecten irr...
High concentrations of mycosporine-like amino acids and colored dissolved organic matter in the sea surface microlayer off the Iberian Peninsula
High concentrations of mycosporine-like amino acids colored dissolved organic matter the sea surface microlayer off Iberian Peninsula
2014/4/16
Mycosporine-like amino acids (MAAs), phytoplankton pigments, and inherent optical properties were analyzed in sea surface microlayer (SSM), near-surface (0–2 m), and subsurface (0–110 m) samples from ...
Seasonal variations in the concentrations of methyl and ethyl nitrate in ashallow freshwater lake
Seasonal variations in the concentrations methyl ethyl nitrate in a shallow freshwater lake
2014/4/16
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 ...
Probability Distribution of Concentrations Measured in the Wake of a Continuous Point Source in Coastal Currents
Continuous Point Source Coastal Currents
2009/3/7
A generalized statistical model is proposed to determine the probability density function of the concentration history measured at a fixed point in the wake of a continuous point source in coastal cur...
Concentrations of Sea-Spray Droplets at Various Wind Velocities: Separating Productions through Bubble Bursting and Wind Tearing
Sea-Spray Droplets Various Wind Velocities Bubble Bursting Wind Tearing
2008/6/26
There are two sets of comprehensive measurements of sea spray: de Leeuw and Smith et al. Their data are interpreted to describe similar productions of film and jet drops by bursting bubbles. For measu...
The interactive effects of calcium concentration and temperature on the survival and reproduction ofDaphnia pulexat high and low food concentrations
calcium concentration temperature on the survival Daphnia pul exat high low food concentrations
2014/4/21
We rearedDaphnia pulexin a fully defined medium at seven calcium (Ca) concentrations (0.1, 0.5, 1, 1.5, 2, 5, and 10 mg Ca L21), two mixed algal densities (high food: 30mg chlorophyllaL21 and low food...
