The refractive index of particulate matter suspended in seawater
is nonuniform and potentially is an indicator of composition and
origin. A method is described for determining the refractive index
distribution. The method requires the measurement of the volume
scattering function and assumes the total size distribution to be
capable of...
The equatorial front in the eastern Pacific Ocean observed during 14 October–7 December, 1971, from R/V Yaquina of Oregon State University is discussed. The front is clearly defined at the sea surface by a large horizontal gradient of temperature, salinity, σt and nitrate. Equatorial upwelling, which is believed to be...

It is shown that the complex index of refraction of a given particle-size distribution may be calculated if the particle extinction coefficient and the particle absorption coefficient are known. If the particles are assumed to be nonabsorbing, a real index of refraction may be calculated from the ratio of light...
Observations made during October and December 1971 on the Yaloc 71 Cruise of Oregon State University indicate the presence of the Cromwell Current on the east side of the Galapagos Islands. Light scattering, particle size distribution, nutrients, and standard hydrographic parameters were measured in water samples collected at 154 stations....
One hundred and seventy pairs of temperature and light transmission profiles were obtained by simultaneous conductivity-temperature-depth (CTD) and light transmissometer casts in three cruises on the R/V Yaquina over the continental shelf off Oregon. These were analyzed for bottom nepheloid layers (BNL) and bottom mixed layers layers (BML). Supplementing these...
