Acoustic–gravity waves from multi-fault rupture [PDF]
Journal of Fluid Mechanics, 2021 The propagation of wave disturbances from a complex multi-fault submarine earthquake of slender rectangular segments in a sea of constant depth is discussed, accounting for both water compressibility and gravity effects.

Theory and analysis of acoustic-gravity waves in a free-surface compressible and stratified ocean [PDF]
Ocean Modelling, 2020 Waves propagate in a free-surface ocean due to compressibility and gravity (and surface tension at much smaller scale). Analytical solutions have long been derived independently for acoustic and gravity waves, i.e., acoustic waves or internal-gravity ...

Acoustic-Gravity Waves Interacting with a Rectangular Trench [PDF]
International Journal of Geophysics, 2015 A mathematical solution of the two-dimensional linear problem of an acoustic-gravity wave interacting with a rectangular trench, in a compressible ocean, is presented. Expressions for the flow field on both sides of the trench are derived.

Nonlinear interaction between acoustic gravity waves
Annales GeophysicaeThe resonant interaction between three acoustic gravity waves is considered. We improve on the results of previous authors and write the new coupling coefficients in a symmetric form. Particular attention is paid to the low-frequency limit.

Hydro-acoustic precursors of gravity waves generated by surface pressure disturbances localised in space and time [PDF]
, 2014 We consider the mechanics of coupled underwater-acoustic and surface-gravity waves generated by surface pressure disturbances in a slightly compressible fluid.

Habitat-Specific Design Strategies for Untethered Soft Robots. [PDF]
Adv Sci (Weinh)Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Electromagnetic oscillations of the Earth's upper atmosphere (review) [PDF]
Annales Geophysicae, 2010 A complete theory of low-frequency MHD oscillations of the Earth's weakly ionized ionosphere is formulated. Peculiarities of excitation and propagation of electromagnetic acoustic-gravity, MHD and planetary waves are considered in the Earth's ...

Brief communication "Seismic and acoustic-gravity signals from the source of the 2004 Indian Ocean Tsunami" [PDF]
Natural Hazards and Earth System Sciences, 2012 The great Sumatra-Andaman earthquake of 26 December 2004 caused seismic waves propagating through the solid Earth, tsunami waves propagating through the ocean and infrasound or acoustic-gravity waves propagating through the atmosphere.

Multistability for nonlinear acoustic-gravity waves in a rotating atmosphere.
Chaos, 2021 The multistable states of low-frequency, short-wavelength nonlinear acoustic-gravity waves propagating in a small slope with respect to the vertical ones are explored in a rotating atmosphere.
