Effect of Sea Water on Concrete01:22

Effect of Sea Water on Concrete

Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.

Propagation of Waves01:07

Propagation of Waves

When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
Reflection of Waves01:07

Reflection of Waves

When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...
Potential Due to a Polarized Object01:29

Potential Due to a Polarized Object

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
Electrostatic Boundary Conditions01:16

Electrostatic Boundary Conditions

Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.
The surface integral of an electric field is given by Gauss's law in integral form and is related to...
Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance. Over a...

Summary

Variability in ocean color remote sensing reflectance was linked to inherent optical properties and particle size distribution. Particle type strongly influenced the f/Q ratio, with best optical model closure in mixed waters.

Area of Science:

  • Ocean optics
  • Remote sensing science
  • Inherent optical properties

Background:

  • In situ remote sensing reflectance [r(rs)(lambda,4 m)] and the f/Q ratio are key parameters in oceanographic studies.
  • Understanding variability sources is crucial for accurate ocean color data interpretation.

Purpose of the Study:

  • Investigate sources of variability in [r(rs)(lambda,4 m)] and f/Q ratio.
  • Evaluate the impact of particle characteristics on optical closure using a radiative transfer model.

Main Methods:

  • Collected an optical dataset on a mooring in the Santa Barbara Channel.
  • Employed radiative transfer modeling and statistical analyses.
  • Applied a semianalytical radiative transfer model.

Main Results:

  • Variability in inherent optical properties and particle size distribution slope (xi) strongly correlated with [r(rs)(lambda,4 m)] variability.
  • Particle type characteristics significantly affected f/Q ratio variability.
  • Optical closure was best achieved in waters with mixed biogenic and minerogenic particles.

Conclusions:

  • Inherent optical properties and particle size distribution are primary drivers of [r(rs)(lambda,4 m)] variability.
  • Particle composition is critical for understanding f/Q ratio dynamics.
  • Mixed particle assemblages enhance the accuracy of radiative transfer models in optical studies.
