First Observations of Large-Scale Wave Structure and Equatorial Spread F Using Certo Radio Beaconon the C/NOFS Satellite
First observations of large-scale wave structure and the subsequent development of equatorial spread F, using total electron content derived from the ground based reception of beacon signals from the CERTO…

Community Structure of Archaea in the Water Column Above Gas Hydrates in the Gulf of Mexico
In this study, we presented the 16S rDNA sequences and lipid profiles in the context of water chemistry to characterize the archaeal community structure above a gas hydrate mound (MC…

C/NOFS and Radar Observations During a Convective Ionospheric Storm Event Over South America
Evidence for seeding by both gravity waves and the Kelvin-Helmholtz instability is presented.

Backscatter Lidar Observations of Lower Tropospheric Dynamics During Southern California Wildfires
Wavelike features suggesting gravity waves were revealed by lidar observations (from El Segundo, California) of smoke layers produced by large wildfires in the Southern California region during a Santa Ana…

Calculating Protoplanet Collisions in the Early Solar System
We study shock-synthesized high-pressure phases in meteorites in infer the conditions under which they formed. These phase are found in or adjacent to locally melted veins or pockets that formed…

Temperature Dependent Nonlinear Absorption in InSb
Temperature dependent two-photon and free-carrier absorption spectra of InSb are measured using femtosecond, picosecond, and nanosecond IR sources. Measurements over this substantial range of pulsewidths give results consistent with a…

Spectral and Temperature Dependence of Nonlinear Absorption in InSb
Temperature dependent two-photon and free-carrier absorption spectra of InSb are measured using a tunable picosecond source via temperature controlled Z-scan experiments and show good agreement with theoretical predictions.

On the Charging of Mesospheric Dust
We consider the charging of dust grains, taking into account charging by thermal plasma and possible high energy particles, for a range of grain sizes. We also consider the effect…

Radar and Rocket Comparison of UHF Radar Scattering from Auroral Electrojet Irregularities: Implications for a Nanosatellite Radar
This article presents the estimates for UHF radar volume scattering coefficient of auroral electrojet irregularities based on previous measurements of absolute radar scattering coefficients and in situ rocket spectra.

Pfisr Observations of Strong Azimuthal Flow Bursts in the Ionosphere and Their Relation to Nightside Aurora
We present two flow burst events observed by the new Poker Flat Advanced Modular Incoherent Scatter Radar (PFISR) in the pre-midnight auroral zone on 28 April 2007, one towards the…

Poker Flat Radar Observations of the Magnetosphere-Ionosphere Coupling Electrodynamics of the Earthward Penetrating Plasma Sheet Following Convection Enhancements
We have used PFISR observations associated with two relatively abrupt southward turnings of the IMF to provide an initial evaluation of aspects of this response.

Spectral Observations of Polar Mesospheric Summer Echoes at 33 Cm (450 Mhz) with the Poker Flat Incoherent Scatter Radar
We report on multi-beam spectral observations of polar mesospheric summer echoes (PMSE) at 450 MHz (Bragg scattering wavelength of ∼33cm) carried out with the Poker Flat Incoherent Scatter Radar (PFISR)…
