A method is presented for determining the significant parameters, maximum wind speed and radius of maximum wind speed, of the surface winds associated with a hurricane. The method is based on Bayesian inversion, using Markov chain Monte Carlo sampling. Underwater acoustic measurements are used to estimate parameters in the axisymmetric Holland model for hurricane surface winds.

During the long course of evolution, fish have developed complex skin structures to adapt to the dynamic aquatic environment. These skin features not only reflect optimal adaptation to the aquatic environment but also play a key role in effectively reducing fluid drag and improving swimming efficiency, to reveal the intrinsic connection between the complex skin structure of fish and drag reduction performance and to provide new design ideas for the drag reduction surface of underwater vehicles. Based on the different drag reduction characteristics of fish skin structures, this paper divides existing biomimetic drag reduction technologies into three categories: riblet drag reduction, flexible drag reduction, and composite drag reduction.

Boat noise has been shown to distract and cause harm to many marine organisms. Most of the study effort has focused on fish & marine mammals, even though invertebrates represent over 92 % of all marine life. The few studies conducted on invertebrates have demonstrated clear negative effects of anthropogenic noise pollution.

Conventional techniques for underwater source localization have traditionally relied on optimization methods, matched-field processing, beamforming, and, more recently, deep learning. However, these methods often fall short to fully exploit the data correlation crucial for accurate source localization. This correlation can be effectively captured using graphs, which consider the spatial relationship among data points through edges.

The dwarf cuttlefish, (formerly ), is a coleoid cephalopod like octopus and squid, and an emerging model organism for scientific research. Dwarf cuttlefish can change the color, pattern, and texture of their skin in milliseconds to camouflage with their surroundings and communicate with conspecifics. Their skin displays are directly controlled by the brain.
