Applicability of Information Theory to the Quantification of Responses to Anthropogenic Noise By Southeast Alaskan Humpback Whales
We assess the effectiveness of applying information theory to the characterization and quantification of the affects of anthropogenic vessel noise on humpback whale (Megaptera novaeangliae) vocal behavior in and around…

Using PFISR Measurements and Gravity Wave Dissipative Theory to Determine the Neutral, Background Thermospheric Winds
Understanding the propagation and dissipation of an atmospheric gravity wave (GW) in the thermosphere requires an accurate dissipative GW dispersion relation, the GW's horizontal wavelength and period, and the background…

Using Spectral Characteristics to Interpret Auroral Imaging in the 731.9 Nm O+ Line
Simultaneous observations were made of dynamic aurora during substorm activity on 26 January 2006 with three high spatial and temporal resolution instruments: the ASK (Auroral Structure and Kinetics) instrument, SIF…

Validation of OMI Tropospheric NO2 Column Data Using MAX-DOAS Measurements Deep Inside the North China Plain in June 2006: Mount Tai Experiment 2006
We performed observations of the tropospheric NO2 column using the ground-based Multi-Axis Differential Optical Absorption Spectroscopy technique in the North China Plain.

Cross Sections and Reaction Rates for Comparative Planetary Aeronomy
In this chapter we describe the current knowledge of a selection of collision processes and chemical reactions of importance to planetary aeronomy.

Independent Emission and Absorption Abundances for Planetary Nebulae
In this study we observe UV resonance line absorption in the central stars of PNe produced by the nebular gas and from the same ions that emit optical forbidden lines.

Semi-Empirical Formulas of Drag/Lift Coefficients for High Speed Rigid Body Manoeuvring in Water Column
Falling of rigid body through water column with high speed is investigated experimentally and theoretically. Several experiments were conducted to shoot rigid bodies with the density ratio higher than 1…

Enhanced Ion Acoustic Lines Due to Strong Ion Cyclotron Wave Fields
The Fast Auroral Snapshot Explorer (FAST) satellite detected intense and coherent 5–20 m electric field structures in the high-latitude topside auroral ionosphere between the altitudes of 350 km and 650…

PFISR Nightside Observations of Naturally Enhanced Ion Acoustic Lines, and Their Relation to Boundary Auroral Features
We present results from a coordinated camera and radar study of the auroral ionosphere conducted during March of 2006 from Poker Flat, Alaska.

Wavelength Dependence of the Es Layer Instability, and of Coupling to the F Layer, in the Nonlinear Regime
We show that longer wavelengths grow to larger amplitudes before eventual nonlinear saturation, and couple more effectively to the F-region.
