We developed an environmentally adaptive under‐ice navigation framework that was
deployed in the Arctic Beaufort Sea during the United States Navy Ice Exercise in March …

The seabed data from the Kara Sea (a part of the Arctic Shelf) are used to build a low-
frequency (up to 250 Hz) acoustic waveguide model and study sound propagation in this …

Accurate modeling of sound propagation in ice-covered ocean environments can help with
interpreting discrepancies between predictions and experimental observations in the …

The Pacific Arctic Region has experienced decadal changes in atmospheric conditions,
seasonal sea-ice coverage, and thermohaline structure that have consequences for …

An ocean-ice-acoustic coupled model is configured for the Beaufort Sea. The model uses
outputs from a data assimilating global scale ice-ocean-atmosphere forecast to drive a …

Increased knowledge about marine mammal seasonal distribution and species assemblage
from the South Orkney Islands waters is needed for the development of management …

Complexities of acoustic propagation in ducts have long been known, eg, shallow water
environments and deep waters off Gibraltar. The “Beaufort Lens”(Lens) is a duct north of …

Climate induced changes in the Arctic Ocean have severely impacted underwater acoustic
communication and navigation; understanding underwater noise characteristics is critical to …

This work examines three-dimensional (3D) propagation caused by interaction with the sea
ice canopy using an approximate normal mode/parabolic equation hybrid model. The effects …

The Beaufort duct (BD) is a subsurface sound channel in the western Arctic Ocean formed
by cold Pacific Winter Water (PWW) sandwiched between warmer Pacific Summer Water …
