The stoichiometric model of organic decomposition in seawater
(Redfield, Ketchum, and Richards, 1963) was used to describe the
oceanic distribution of total carbon dioxide. It was assumed that the
concentration of total carbon dioxide was the sum of three terms:
(1) the initial concentration of carbon dioxide, (2) the increase...
Dissolved oxygen profiles made with an in situ polarographic
device reveal structure in the form of inversions and gradient
changes in the 100-600 meter depth zone off Oregon. Inversions
10-70 meters thick are traced over distances of 40 miles in some
cases and are bracketed by a distance of 8...
Manual and automatic solvent extraction techniques were used
to concentrate organic material from natural waters. Field and
laboratory extractions were compared to determine the most probable
method and best solvents for efficient concentration of organic
material from estuarine and sea waters.
The large scale extraction processes utilizing extractors made
from...
