Summary: The study found that using fyke nets on the marsh platform of living shorelines can catch more fish and record higher species richness compared to natural marsh shorelines. However, there were no significant differences in fish abundance in the shallow unvegetated habitats seaward of the different shoreline types.

Summary: Multibeam forward-looking sonar (MFLS) plays a crucial role in underwater detection. However, there is a lack of available datasets and the sonar image processing methods are not suitable for research in artificial intelligence (AI) areas. To address these challenges, a new dataset called underwater acoustic target detection (UATD) is introduced, which consists of over 9000 MFLS images captured using Tritech Gemini 1200ik sonar. The dataset provides raw sonar image data with annotations of 10 categories of target objects and can be used to verify the practicality of state-of-the-art detectors.

Summary: Acoustic cameras are being increasingly used in monitoring diadromous fish populations, but identifying anguilliform fish automatically from the data is challenging. This study developed a computer vision-based method to automatically detect, identify, and count anguilliform fish using data from multiple models of acoustic cameras. Promising results were obtained for large eels, with over 75% being successfully identified, but the detection rate for smaller eels was only 42%, with the best performance observed at detection ranges of 4-9 m. Despite the need for improvements, the cross-camera method shows promise for automatically detecting and counting large eels in long-term monitoring studies in complex environments.

Summary: In this paper, a new method is proposed for calibrating a hybrid sonar-vision system using motion comparisons between images. The transformation matrix between the camera and the sonar can be computed and the camera's focal length can be estimated. The advantage of this method is that it does not require a specific calibration pattern.

Summary: The study aimed to improve underwater excavation imaging using acoustic survey methods. Scanning sonar was found to be more effective than other sonar devices in turbid underwater environments. When combined with high-frequency geophysical exploration techniques, scanning sonar can significantly increase the reliability of underwater relic investigations.

Summary: This study proposes an autonomous surface vehicle (ASV)-based structural monitoring system for inspecting power cable lines under the ocean surface. The system uses multimodal sonar sensors to generate maps of the target objects. A field test conducted in an ocean environment confirms the efficiency of the proposed monitoring system.

Summary: Only approximately 20% of the global seafloor topography has been finely modeled, with satellite altimetry and multibeam sonar bathymetry offering different levels of precision. Applying deep learning techniques can effectively improve the accuracy of bathymetry data obtained from satellite altimetry, providing a novel method for accurate modeling of the seafloor topography.

Summary: Understanding the behavior of marine animals around tidal turbines is crucial for assessing their impact on individuals and populations. A study using multibeam sonar data near an operational turbine in Scotland identified tracks of marine mammals, fish, and diving birds. The data is being analyzed to study species reactions to turbine rotors and improve automated detection and classification algorithms.

Summary: This study presents a framework for estimating the abundance of migrating fishes by combining count data from a sonar with movement data from acoustic telemetry. The framework utilizes a Bayesian integrated model to estimate spawning run abundance of lake sturgeon. This approach can be applied to other migratory fishes in riverine systems.

Summary: This study evaluates the performance of imaging sonars at different frequencies for small target detection. The results show that target detection quality decreases with increasing range, and the low-frequency mode has a longer detection range under shallow water conditions.

Summary: Entrainment and mortality of freshwater fish at hazardous pumping station intakes used for Flood Risk Management (FRM) are a global concern. This study investigated the diel movements of river-resident fish in response to various factors and proposed non-engineered management options to protect these fish from entrainment.

Summary: This study presents an efficient method for detecting and quantifying gas leaks using a 300 kHz multibeam sonar, which isolates interference objects based on the backscattering strength of gas bubbles and the characteristics of gas plumes. An optimization model for volume-scattering strength is proposed to estimate gas flux, and experimental results validate the effectiveness and accuracy of the method.
