Eyes on the water: How local mariners can accurately detect a submerged human proxy in shallow nearshore coastal water with modern recreational fish finders

Journal of Forensic Sciences, EarlyView.
Abstract It has recently been demonstrated that modern recreational fish finders with high‐frequency (800 kHz) Sidescan transducers can detect submerged human bodies. This ubiquitous technology is widely used on the water and has the potential to be utilized for the rapid detection of submerged decedents in any waterbody.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Enhancing underwater target detection: Fusion of spatio‐temporal incompletely‐aligned AIS and sonar information via DTW and multi‐head attention mechanism

IET Radar, Sonar & Navigation
In the field of underwater target detection, the passive sonar is an important means of long‐distance target detection. The sonar detection information typically includes both surface and underwater targets, whereas it is a great challenge on effectively

Common ground: Efficient, consistent, observer‐independent bioacoustic call density estimation with adjudicated ground truth and capture–recapture detection functions

Methods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic recording is a cost‐effective method for monitoring vocal animals. Within this field, there is an increasing focus on automated detection algorithms for counting calls and estimating call density (in space and time). For accurate interpretation of such results, it is important to understand and correct biases introduced by ...
