Summary: The study aims to fill a knowledge gap by measuring the relative influence of perceived risk of sound and prey patch quality on decision-making and foraging success in grey seals. Results suggest that foraging context is important in interpreting avoidance behavior and predicting the effects of anthropogenic activities. Future studies should consider foraging context and other contextual factors such as behavioral state and habitat quality.

Summary: Estuaries worldwide have undergone modifications over centuries, impacting sediment dynamics. The Coos Bay Estuary in Oregon, a small estuary with complex geometry, has experienced significant changes since 1865, leading to alterations in tidal amplitudes, salinity intrusion, and estuarine flow. These changes have resulted in reduced current magnitudes, increased stratification, and the formation of an estuarine turbidity maximum supplying sediment to proximal embayments.

Summary: Global reductions in underwater radiated noise levels from cargo vessels are necessary to mitigate the accumulative impacts on marine wildlife. By utilizing a vessel exposure simulation model, we demonstrate that reducing vessel source levels through slowdowns and technological modifications can significantly decrease the area exposed to ship noise. Furthermore, despite the longer duration it takes for a slower vessel to pass an animal, slowdowns effectively mitigate all impacts to marine mammals. Hence, we suggest implementing speed reductions as an immediate solution to reduce cumulative noise impacts, which can be scalable from local areas to global ocean basins. Additionally, routing vessels away from critical habitats and employing technological modifications to minimize vessel noise can further supplement these efforts.

Summary: Landscape change has an impact on species distribution, and understanding these changes is crucial for ecology and conservation. In addition to landscape features, the presence of syntopic species plays a significant role in explaining species distribution, with synergistic effects observed for most species.

Summary: This study exposed small-spotted catshark specimens to different acoustic conditions and found that the animals tended to increase swimming time and avoid noisy areas when subjected to higher amplitude levels of noise. Despite the increasing interest in anthropogenic noise effects on marine wildlife, few studies have investigated the potential role of underwater noise on elasmobranch species.

Summary: Concerns about environmental impacts of air gun surveys drive research on marine vibroseis systems which produce lower acoustic pressure but longer duration signals compared to air guns. Studies show more behavioral disturbance for marine mammals with MV arrays than air gun arrays.

Summary: Bycatch is a major cause of marine mammal mortality worldwide, and computer-based procedures can help explore population dynamics and estimate removal levels under different scenarios. Potential Biological Removal (PBR) and Removals Limit Algorithm (RLA) are control rules tested in the Management Strategy Evaluation framework to ensure conservation objectives are met amidst uncertainties. The RLA package in R software was developed to assess removal limits in marine mammal conservation, with case studies conducted under the auspices of OSPAR Marine Mammal Expert Group.

Summary: This article presents a framework for assessing the relative risk of human activities on marine vertebrates, with emphasis on sound-producing activities. The objectives are to provide tool for managers to evaluate potential biological risk, identify data gaps, and suggest measures to reduce risk. Current regulatory assessments of human activities on marine mammals focus on generalized exposure and effects, while this framework considers spatial-temporal-spectral intersections and specific examples of offshore wind farms.

Summary: Reservoir sedimentation poses a significant threat to water supply, and this study explores an optimized approach to reservoir management using dynamic programming neural networks to minimize the gap between water releases and irrigation demands. The results demonstrate that dredging operations can effectively address reservoir sedimentation and enhance water demand satisfaction rates, highlighting the importance of incorporating dredging into holistic dam management strategies.

Summary: This paper discusses the increasing threat of anthropogenic noise to marine mammals and the mechanisms of auditory masking. Laboratory hearing experiments are conducted to study tone detection in different types of noise, mechanisms for controlling masking release, the role of temporal resolution, and the differences between energetic and informational masking.

Summary: The study investigated the trophic interaction between invasive pumpkinseed sunfish and Chaoborus larvae in response to motorboat noise, finding that the noise decreased the maximum feeding rate in fish that had not been previously exposed to it, but the distraction effect weakened with repeated exposure.

Summary: The study performed noise propagation modeling on six commercial ADD models and a 'fictional' ADD, exploring potential auditory impacts on marine mammals. It predicted that real ADDs could cause Temporary Threshold Shift (TTS) to Very High Frequency (VHF) cetaceans within ranges of 4-31 km.

Summary: This study analyzed data from detectors deployed at an offshore O&G production platform to investigate the acoustic activity of harbor porpoises. The results showed a decrease in porpoise detections following platform construction and drilling operations, but detections returned to baseline levels within a few months. The findings have important implications for Environmental Impact Assessments and the long-term effects of platform presence on marine mammals.
