Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Decadal‐Scale Bathymetric Change in a Shallow Coastal Bay
Abstract Coastal marshes and bays must accumulate sediment to maintain their position relative to mean sea level during periods of sea level rise (SLR). Resuspension of bay‐bottom sediment, which together with tidal inundation promotes marsh deposition, is sensitive to water depth, but quantitative measurements of bathymetric change across shallow bays

Active sonar performance modelling for Doppler-sensitive pulses
Accurate sonar performance modelling is essential to predict likely detection ranges that can be obtained by employing active anti-submarine warfare sonars. Reverberation forms an important source of interference for active sonar performance, the effects

Acoustic Detection of Underwater Air Bubbles Generated by Breaking Waves in an Antarctic Polynya
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.

Radical‐Mediated Dispersion Breaks Aggregation Limits in Carbon Thermoelectrics
We report a rationally designed small molecule (OTN) that effectively disperses SWCNTs via π–π and radical‐radical interactions, yielding hybrid films with a record power factor of 30.1 µW cm−1 K−2 and excellent flexibility. A nine‐leg device achieves a record normalized power density of 0.653 µW cm−2 K−2, setting a new benchmark for carbon‐based ...

Abstract Hydraulic transient‐based techniques are increasingly applied for non‐intrusive condition assessment of buried water pipelines. This study presents systematic field experiments comparing active and passive approaches within the asbestos cement water supply network at the University of Canterbury.

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 ...
