THE view has been expressed that “the much-admired dark blue of the deep sea has nothing to do with the colour of water, but is simply the blue of the sky seen by reflection” (Rayleigh's “Scientific Papers,” vol. 5, p. 540, and NATURE, vol. 83, p. 48, 1910). Whether this is really true is shown to be questionable by a simple mode of observation used by the present writer, in which surface-reflection is eliminated, and the other factors remain the same. The method is to view the surface of the… 
Ocean-Colour Radiometry: Achievements and Future Perspectives
The era of ocean-colour remote sensing may be said to have begun in 1978, with the launch of the Coastal Zone Color Scanner (CZCS) by NASA. In the following three decades, ocean colour has grown in
Optical backscattering and submerged source techniques for characterizing the optical properties of the ocean
avDroved: J. Ronald V. Zaneveld Characterizing the optical properties of the ocean has traditionally involved measuring daylight submarine light-field quantities, most commonly plane irradiance and
Raman effect: History of the discovery
The paper gives a historical account of the discovery of the Raman Effect, starting from Raman's voyage to Europe through the Mediterranean Sea in the summer of 1921 to the observation of modified
C. V. Raman and Colonial Physics: Acoustics and the Quantum
Presenting the social and historical context of Chandrasekhara Venkata Raman, this paper clarifies the nature and development of his work in early twentieth-century colonial India. Raman’s early
Physical Oceanography in India: An Historical Sketch
Anthropologists and archaeologists agree that the beginning of civilization in India was around 4000 B.C. in the northwestern and central areas. Not much is known about the early period, but it is
Spectroscopic view of life and work of the Nobel Laureate Sir C.V. Raman.
The life and work of Sir C.V. Raman is presented and brief review of the uses of Raman spectroscopy in urology are reviewed.
Illuminating disease and enlightening biomedicine: Raman spectroscopy as a diagnostic tool.

Noninvasive Detection of Filaggrin Molecules by Raman Spectroscopy
The Raman effect consists of a shift in photon energy due to inelastic collisions of photons with molecules. These wavelength shifts are unique for each molecule, and they provide a fingerprint of
