Measurement of Submarine Daylight

A Discrepancy between Calculation and Measurement of Submarine Illumination.

SCRIPPS INSTITUTION OF OCEANOGRAPHY,* UNIVERSITY OF CALIFORNIA, LA JOLLA, CALIFORNIA Communicated by Carl L. Hubbs, August 5, 1955 An investigation of the behavior of the sonic-scattering layer in the region of the San Diego Trough has proved that it is closely associated with the degree of submarine illumination.' This finding could not have been predicted by extrapolating from light measureme...

Measurement of submarine groundwater discharge in Kahana Bay, O‘ahu, Hawai‘i

Submarine groundwater discharge (SGD) is neither well understood nor commonly investigated in Hawai‘i, but it is recognized as a potential pollution source to coastal environments. Between 1998 and 2000, this study located and quantified both total SGD and the terrestrial SGD fraction ( ftgw) in Kahana Bay, O‘ahu. CTD casts were used to profile the water structure and identify potential areas o...

The Chemistry of Daylight Vision

1. While several reports of photosensitive pigments from the retinas of animals possessing large numbers of cone cells have been published, the only study which could be confirmed was Wald's discovery of iodopsin, a red-sensitive pigment from chicken eyes. 2. In its chemical properties, such as the range of pH stability and the effect of polar organic solvents, iodopsin resembles rhodopsin but ...
