Current meter moorings maintained over the Oregon continental shelf in 1973 and 1975 clearly show the difference between winter and spring oceanographic regimes and the rapid transition between the regimes. In winter the mean alongshore current is northward at all depths and strongest near shore; there is no mean vertical...
Even slight terrain inhomogeneities can cause large horizontal variations in the clear, stably stratified, nocturnal boundary layer largely through cold air drainage. By early morning the valleys and depressions can be several degrees cooler than the adjacent slopes and plateaus. As surface heating begins in the morning, these horizontal variations...
A new continuous wave sonic anemometer was constructed using inexpensive ultrasonic transducers and phase-locked loop integrated circuitry. Vertical wind is measured by sensing the difference in phase between sound waves traveling in the +g and −z directions. The direction of sound travel is reversed 78 times per second, so the...
Polyethylene film controlled release packets utilizing ethylene dibromide (EDB) and pdichlorobenzene
(PDB) were designed and tested against late instar larvae of Galleria mellonella
(L.). EDB controlled release packets gave 100% control of larvae in 48 h under
experimental conditions at 26.6° and 32.3°C. PDB controlled release packets gave 13.3 and...
The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping bottom and with small-amplitude alongshore variations in topography is utilized. Perturbation methods and numerical inversion of Fourier transforms are employed. The effect...
We have developed a method for the determination of the orientational distribution function of partially ordered systems from the EPR line shape that is an alternative to the usual one of expansion in the elements of the Wigner rotation matrices. The method can be applied to distribution functions whose expansion...
An experimental investigation of a two·dimensional turbulent jet in a quiescent environment has been
carried out to determine the structural characteristics of the outer, intermittent turbulent motion. An
overall picture of this motion was deduced from the results which indicate that, on the average, the
turbulent bulges are of the...
The nonexponential phosphorescence decay of a highly folded form of poly-riboadenylic acid (poly rA) with noncovalently bound dye is explained by a novel application of a well-known theory of electronic excitation transfer based on the Förster mechanism. This theory, originally used to describe singlet-singlet energy transfer from donor molecules to...
Measurements of total irradiance versus depth and beam transmission versus depth were made at
stations near shore along the west coast of the North and South American continents. The water types at
each station were optically classified according to the system of Jerlov (1976), thus providing additional
information for the...
