Synoptic Measurement of Dynamic Oceanic Features
Synoptic Measurement Dynamic Oceanic Features
2015/8/10
Shore-based radar systems operating at the high-frequency (HF) mode are becoming a widely used and accepted tool for measuring surface currents for coastal oceanographic research. Their history, theor...
Measurement Method of Turbidity Depth Profiles using ADCP for Monitoring of Coastal Sea Area
Turbidity Depth Profiles ADCP Coastal Sea Area
2009/4/8
At stormy weather, dredging and filling operation and so on, the water with high concentrations of solids arises in coastal sea area. Growth of seaweed and algae is obstructed to interrupt sunlight b...
Measurement method of the concentration of matter using optical property of seawater in visible wavelength range
concentration of matter optical property seawater visible wavelength range
2009/4/8
It is known that ocean color depends on contained materials in seawater. It is possible to use it for detecting significant information of sea. Since the reflection and absorbance of light can be ex...
Laboratory Measurement of Heat Transfer and Thermal Structure Near an Air-Water Interface
Laboratory Measuremen Air-Water Interface Thermal Structure Near Heat Transfer
2009/4/3
Experiments have been conducted in a wind-water tunnel to establish a quantitative relationship between wind profile parameters, heat flux through the air-water interface, and the temperature differen...
Measurement of the High-Frequency Spectrum of Ocean Surface Waves
High-Frequency Spectrum Ocean Surface Waves
2009/3/7
High-frequency spectra of wind-generated ocean waves were measured at an ocean research tower of Kyushu University using a fast-response wave recorder and an electronic differentiating circuit. Wind w...
A New Method for Measuring the Directional Wave Spectrum. Part II. Measurement of the Directional Spectrum and Phase Velocity of Laboratory Wind Waves
Directional Wave Spectrum Phase Velocity Directional Spectrum Laboratory Wind Waves
2009/2/23
A new method for measuring the directional spectrum, introduced in the preceding paper (Rikiishi, 1978), has been applied to actual wind waves in a large experimental tank 70 m × 8 m with the water 3 ...
The Mean Circulation East of the Bahamas as Determined from a Recent Measurement Program and Historical XBT Data
expendable-baththermograph Historical XBT Data Mean Circulation
2009/1/21
Observational evidence from a two-ship synoptic survey, from one-year-long current measurements at four sites, and from two independent long-term expendable-baththermograph (XBT) data sets is combined...
Direct measurement of thed13 C signature of carbon respired by bacteria in lakes: Linkages to potential carbon sources, ecosystem baseline metabolism, andCO2fluxes
the d13 C signature bacteria in lakes potential carbon sources ecosystem baseline metabolism CO2 fluxes
2014/4/18
Using a novel method to measure the isotopic signature (d13C) of respiratory CO2 produced by bacterioplankton, we determined the proportion of terrigenous vs. algal-derived organic carbon (OC) respire...
Direct measurement of diffusivity within diatom aggregates containing transparent exopolymer particles
Direct measurement of diffusivity diatom aggregates transparent exopolymer particles
2014/4/22
We present the first direct measurements of apparent diffusivity within diatom aggregates using a diffusivity microsensor. Transparent exopolymer particles (TEP) and aggregate dry mass (TEP and cells)...
