SIDAC-I is a digital analog simulator which permits analog as
well as hybrid simulations to be programmed on a digital computer.
FORTRAN, a scientific computer language, may be included as an
integral part of the SIDAC-I simulation language. The simulator
consists of a controller program and a set of predefined...
I have developed an analytical method for the determination of
molecular hydrogen in seawater. It is based on the change of hydrogen
concentration in a 30 cc. volume of air as it is equilibrated with a
one-liter sample of seawater. The change in hydrogen concentration in
the air is measured...
The interference of sulfide with the colorimetric determination of
nitrite, by the method of Bendschneider and Robinson (1952), can be
eliminated by passing the samples through a cationic exchange resin,
Dowex 50W-X8, in the zinc form. This resin retains sulfide without
affecting nitrite and the technique can be applied to...
Meridional fluxes of silica across the Southern Ocean polar front
are attributed to two different processes which generally act in opposite
directions. Equatorward low frequency fluxes of silica inferred from
ISOS current meter data in the Drake Passage are approximately balanced
by poleward meridional diffusion of silica along surfaces of...
