heal.abstract	Human activities introduce noise, i.e., unwanted sound, into the marine environment either intentionally (e.g., seismic surveys) or unintentionally as a by-product of other activities (e.g., shipping or construction). Anthropogenic noise can be broadly categorized into two main types: pulsed and continuous. Over the last century, underwater noise from human activities has increased significantly, particularly in coastal areas. This is primarily due to construction activities, such as port development and maintenance, offshore wind farms, floating gas storage and transport facilities, dredging, and oil and gas platforms, combined with the growth of global shipping. These noise-generating activities expose marine life to sounds of varying intensity, ranging from very high to chronic lower levels. Recent scientific studies have demonstrated that the increasing prevalence of underwater noise can adversely affect marine animals, many of which rely on sound for essential functions such as communication, navigation, and foraging. To monitor noise and mitigate these effects, several countries have established comprehensive regulatory risk management frameworks, including associated noise thresholds and protocols. These frameworks are periodically updated and integrated into environmental studies, construction, and the operation of marine projects. They also align with more general policies for environmental protection, marine conservation and sustainability, such as the European Marine Strategy Framework Directive (MSFD). In Greece, procedures and protocols exist only for certain activities, such as seismic surveys, within the context of environmental impact assessments, but there is a significant legislative gap for all anthropogenic noise-generating activities and no noise thresholds related to the marine species of concern have been established. Furthermore, a standardized risk management protocol addressing noise monitoring and mitigation actions or measures for reducing the impacts of both pulsed or non- pulsed anthropogenic noise on marine animals is lacking for most noise-generating activities. This work aims to address this gap by proposing a national risk management protocol for underwater noise emissions resulting from specific anthropogenic activities: pile driving (both impact and vibratory) and dredging. Although this proposal can be enhanced and be more detailed, it is expected to contribute to the establishment of a framework for minimizing the impact of underwater noise on specific indicator species of the Greek waters, while at the same time aligning with international best practices, environmental objectives and policies.	en
