Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...

A Statistical Inference Method for Interpreting the CLASP Observations

, 2018
On 3rd September 2015, the Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP) successfully measured the linear polarization produced by scattering processes in the hydrogen Lyman-$\alpha$ line of the solar disk radiation, revealing conspicuous spatial ...

Spatiotemporal Variability in the Vertical Distribution of Phytoplankton Biomass in the Ice‐Free Southern Ocean: A Bioregionalization Approach

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract The Southern Ocean plays a major role in the global oceanic sink of carbon dioxide (CO2). However, substantial uncertainties remain regarding how phytoplankton production influences this carbon sink. Observations of the spatiotemporal variability in vertical phytoplankton biomass distribution are therefore essential to advance our ...

Modeling aeroacoustic excitations by subsonic wave packets in the Kirchhoff formalism [PDF]

, 2013
The present work aims at linking the shape of a wave packet to its acoustic e ciency through numerical integration of the homogeneous Helmholtz equation in the Kirchho formalism.

A New Orthogonal Geomagnetic Coordinate System: The Generalized Eccentric Dipole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The study of near‐Earth plasma environment relies heavily on accurate geomagnetic coordinate systems, mainly because the plasma motion is controlled by the E×B $\boldsymbol{E}\times \boldsymbol{B}$ drift and thus is constrained by the structure of the magnetic field.

Consistency of holonomy-corrected scalar, vector and tensor perturbations in Loop Quantum Cosmology

, 2012
Loop Quantum Cosmology yields two kinds of quantum corrections to the effective equations of motion for cosmological perturbations. Here we focus on the holonomy kind and we study the problem of the closure of the resulting algebra of constraints.

Design and construction of a Cherenkov imager for charge measurement of nuclear cosmic rays

, 2011
A proximity focusing Cherenkov imager called CHERCAM, has been built for the charge measurement of nuclear cosmic rays with the CREAM instrument. It consists of a silica aerogel radiator plane across from a detector plane equipped with 1,600 1" diameter ...
