This legislation directs the Under Secretary of Commerce for Oceans and Atmosphere to undertake a significant project. The primary objective is to improve forecasts of coastal marine fog , thereby enhancing vessel safety and reducing the economic consequences associated with such events. To achieve this goal, the project will focus on several key areas. It aims to increase marine-based observations through various Federal and commercial platforms, including buoys, meteorological stations, vessels, and advanced remote sensing technologies. Furthermore, the initiative will work to advance the geographic coverage, resolution, and accuracy of marine fog modeling, including improvements in marine channel forecast capabilities. The bill also emphasizes the importance of effective communication. It requires the National Oceanic and Atmospheric Administration to improve the communication of marine fog advisories and ensure that risks posed by hazardous fog events are conveyed in a manner that supports informed decision-making by the public. Additionally, the project will provide actionable decision support services based on environmental information. Crucially, the Under Secretary is mandated to engage with both public and private stakeholders , as well as Indian tribes, throughout the planning, development, and implementation phases of the project. Within one year of enactment, a comprehensive project plan must be developed, detailing the specific research, development, technology transfer activities, resources, and timelines required to meet the project's objectives.
