Low frequency continuous active sonar
, 2011 Existing sonar systems are commonly deployed at a low duty cycle, i.e. a short transmit signal is used followed by a long listening time. As a result, the target is only illuminated during a short time resulting in only one detection opportunity per ping.

Acoustic Detection of Underwater Air Bubbles Generated by Breaking Waves in an Antarctic Polynya
Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.Abstract The Southern Ocean is a significant sink for anthropogenic CO2 in the atmosphere. The pelagic regions north of sea ice areas primarily absorb atmospheric CO2 via biological productivity and air‐sea gas exchange. The latter is enhanced by the bubbles generated by breaking waves.

Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Riparian landscapes support biodiverse and productive ecosystems that in turn provide valuable services like water filtration and flood attenuation. Extensive anthropogenic modifications to riparian environments have altered natural water connectivity patterns important for ecosystem health, leading to an increased effort to understand and ...

Marine Ecology, Volume 47, Issue 5, September/October 2026.ABSTRACT The Gulf of Maine is a geologically complex environment that supports a high diversity of plankton, invertebrates, and fish, including commercially important species. Its substrate heterogeneity is well known though existing high‐resolution substrate data are limited, hindering effective fisheries management.
