Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Unraveling the role of land use and microbial activity in shaping dissolved organic matter characteristics in stream ecosystems
role of land use microbial activity in shaping dissolved organic matter in stream ecosystems
2014/4/17
Surface water samples were collected from 43 streams distributed throughout watersheds of mixed land use in southern Ontario, Canada. Absorbance and fluorescence spectroscopy with parallel factor anal...
The Effect of Hydrostatic Pressure Fields on the Dispersion Characteristics of Fluid-shell Coupled System
hydrostatic pressure dispersion fluid-shell coupled system wave propagation
2011/9/9
The effect of hydrostatic pressure on the vibration dispersion characteristics of fluid-shell coupled structures was studied. Both fluid-loaded cylindrical shells and fluid-filled cylindrical shells w...
Hydrodynamic characteristics of the surface-piercing propellers for the planing craft
surface piercing propeller boundary element method hydrodynamic characteristics
2011/9/13
Demand for high-speed marine vehicles (HSMVs) is high among both commercial and naval users. It is the duty of the marine vessel’s designer to provide a hull and propulsion system that diminishes drag...
Lagrangian characteristics of continental shelf flows forced by periodic wind stress
Lagrangian characteristics continental shelf flows periodic wind stress
2009/11/11
The coastal ocean may experience periods of fluctuating along-shelf wind direction, causing shifts between upwelling and downwelling conditions with responses that are not symmetric. We seek to unders...

Statistical characteristics irreversible predictability time regional ocean models
2009/11/9
Probabilistic aspects of regional ocean model predictability is analyzed using the probability density function (PDF) of the irreversible predictability time (IPT) (called τ-PDF) computed from an unco...
Radiative characteristics of ice-covered freshand brackish-water bodies
ice optics albedo under-ice irradiance euphotic zone
2009/10/21
The structure and optics of ice and snow overlying bodies of water were studied in the
years 2000–2003. The data were collected in the northern temperate region (nine Estonian and
Finnish lakes...
On the Acoustic Characteristics of a Gulf Stream Cyclonic Ring
Acoustic Characteristics Gulf Stream Cyclonic Ring
2009/4/2
The acoustic properties of a cyclonic Gulf Stream ring have been studied with field data and ray computations. Cyclonic rings represent relatively low sound velocity regions with large horizontal grad...
Observed Anisotropy of Spectral Characteristics of Internal Waves Induced by Low-Frequency Currents
Spectral Characteristics Internal Waves Low-Frequency Currents
2009/3/26
The isotropy of the internal wave field is investigated from short-time spectra of horizontal current measured in the deep sea. A significant anisotropy is detected at high frequencies during most per...
Some Characteristics of Nearshore Currents along the North Shore of Lake Ontario
Nearshore Currents North Shore of Lake Ontario
2009/3/26
In three periods during 1970 representative of spring, summer and fall, the horizontal currents off Oshawa in Lake Ontario were measured at distances of 3, 6, 11 and 16 km offshore. All records were s...
