This study investigates the polarization and magnetooptic properties of single-mode fibers. These are important for the development of single-mode fiber applications such as interferometric and electromagnetic field sensors and coherent communication systems, which rely on the polarization state of the light. Various linear, circular and induced birefringence effects cause mode...
High-resolution measurements of salinity, temperature, and partial pressure of carbon dioxide (pCO2) taken at Whiskey Creek Shellfish Hatchery, Netarts Bay, Oregon, from 2014 - 2019 are provided in this data set. Briefly, a permanently submerged pipe draws in bay water to supply the shellfish hatchery tanks. Unmodified water is branched...
Much has been accomplished in the last few years
toward the conservation of natural resources, and in
this work the engineer has taken a leading part. The
prevention of unnecessary waste, the utilization of
hitherto useless by-products, and the economic production of the world's necessities are important features of this...
Netarts Bay is a shallow, temperate, tidal lagoon located on the northern coast of Oregon and site of the Whiskey Creek Shellfish Hatchery (WCSH). Data collected with an automated flow-through system installed at WCSH capable of high-resolution (1 Hz) pCO2 and hourly TCO2 measurements, with measurement uncertainties of <2.0% and...
Volcanism is an agent of major disturbance in many parts of the world. While the effects of volcanic disturbance are fairly well-known among some groups of species, few studies have been performed in bird communities. Likewise, few studies have attempted to compare how communities in temperate and tropical biomes respond...
The polarization state of light in a single mode optical fiber may
be changed by linear and circular birefringence intrinsic to the fiber
or introduced by stress in the fiber due to external pressure, bends or
twists. Rotation of polarization may also occur in the absence of any
intrinsic or...
The 4s³P₁ state of argon decays radiatively by a resonance
transition to the 3p⁶¹S₀ ground state; the wavelength of this radiation
is 1067A. By direct observation of the decay of the 1067A radiation
from excited argon gas, a value of 0.93±0.06 x 10⁻⁵ seconds
has been obtained for the natural...
In order to observe laser phase noise, this noise must be converted to
amplitude noise, which can be achieved using either an interferometer or an
absorption resonance in an atomic/molecular vapor or gas. When phase noise is
converted to amplitude noise, it is manifested as a heterodyne signal in the...
The atmospheric sodium daytime abundance was measured for
Corvallis, Oregon, using direct absorption of sunlight by atmospheric
sodium atoms, as observed with an optical waveguide spectrum analyzer.
The disadvantage of the spectrum analyzer is that it can't resolve the
sodium D-lines (Its resolving power is 0.5 nm, which is approximately...
