INTRODUCTION
The impacts of the Novel Coronavirus (COVID-19) on the marine transportation system are widely felt and evolving quickly. Public agencies at all levels of government with stewardship and regulatory responsibilities over the marine transportation system which includes ocean shipping, harbor operations, seaports, ferry systems, cruise ships, offshore industries, barge operations, and inland waterway systems, are scrambling to understand the current and potential effects on operations, workforce, supply chains, and the traveling public. Private sector marine transportation operators and service providers are looking to the government and science-based institutions for guidance and are seeking relevant research findings, best practices, lessons learned, information on the current state of marine transportation, and projections for what may be coming next as the effects of the Coronavirus pandemic intensify and induce systemic impacts. As part of the National Academies of Sciences, Engineering, and Medicine, the Transportation Research Board (TRB) provides leadership in transportation improvements and innovation through trusted, timely, impartial, and evidence-based information exchange, research, and advice regarding all modes of transportation. TRB has reach into the largest transportation researcher and practitioner pool in the world. We are responding to the urgent need for the rapid dissemination of existing research, research in progress, and the current state of understanding by curating lists of relevant resources from authoritative entities. This document includes links to authoritative and credible sources relevant to pandemic response and guidance that directly pertains to the maritime sector.
