Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Perceptual strategies in active and passive hearing of neotropical bats [PDF]

open access: yes, 2008
Basic spectral and temporal sound properties, such as frequency content and timing, are evaluated by the auditory system to build an internal representation of the external world and to generate auditory guided behaviour. Using echolocating bats as model

Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate- and shallow diving toothed whales during exposure to naval sonar

open access: yesFrontiers in Physiology, 2012
Naval sonar has been accused of causing whale stranding by a mechanism which involves formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased decompression sickness (DCS) risk, is thought to result from changes in ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

open access: yesSedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

open access: yesTerra Nova, EarlyView.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Examination of time-reversal acoustic application to shallow water active sonar systems [PDF]

open access: yes, 2000
The ability to employ effectively an active sonar system in the littoral regions is of great interest to the United States Navy. Time-varying multipath propagation introduces significant problems that must be overcome in the employment of shallow water ...

High-Resolution Sonars: What Resolution Do We Need for Target Recognition?

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Target recognition in sonar imagery has long been an active research area in the maritime domain, especially in the mine-counter measure context. Recently it has received even more attention as new sensors with increased resolution have been developed ...

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.
