“…Our oceans are responsible for the carriage of around 80% of world trade and are the lifeblood of many national economies which rely heavily on fishing and tourism 27,34,36,37 . Here, using electronic vessel monitoring systems we quantify and map changes in ship-based activities to provide a comprehensive overview of how multiple national lockdowns to counter COVID-19 have impacted maritime traffic.…”

“…The global ocean has historically played a key role in transport of goods and services and more recently oil and gas exploration and tourism. Prior to the COVID-19 outbreak, there was a longterm acceleration of maritime activities in intensity and occupancy, including shipping and cruise tourism among others 35,36 , with increasing rates of shipping in 92% of the EEZs 30 , and forecast increases of the global shipping network of 240-1,209% by 2050 17 . Our analyses thus provide an unparalleled opportunity to assess changes on the blue economy at global and regional scales.…”

The COVID-19 pandemic has resulted in unparalleled global impacts on human mobility. In the ocean, ship-based activities are thought to have decreased due to severe restrictions and changes in goods consumption, but little is known of the patterns of change, which sectors are most affected, in which regions, and for how long. Here, we map global change of marine traffic during the COVID-19 pandemic and assess its temporal variability at a fine-scale in one of the most affected regions, the Mediterranean Sea. Nearly 44.3% of the global ocean and 77.5% of national jurisdictions showed a decrease in traffic density during April 2020, when strictest confinement measures took place, showing a clear disruption in comparison with previous trends and future projections. Decreases mainly occurred in coastal areas and were more marked and longer lasting in sectors other than cargo and tanker shipping. Our results provide guidance for large-scale monitoring of the progress and potential effects of COVID-19, or other global shocks, on the blue economy and ocean health.

“…In conclusion, taking into account i) that the interest in the economic potential of the oceans is escalating (Bennett et al, 2019;Jouffray et al, 2020), ii) that many human activities at sea causing significant MNP as a by-product (e.g. maritime traffic) keep increasing (Sardain et al, 2019) and iii) that the Mediterranean Sea is densely populated and is a crucial crossroad for many maritime routes, there is no reason to expect that MNP will decrease in the next future, unless innovative technical solutions, specific rules/laws and/or good practices are systematically adopted.…”

Highlights (3 to 5 bullet points, maximum 85 characters, including spaces, per bullet point, to be submitted in a separate editable file in the online submission system, using 'Highlights' in the file name). • Marine noise is a widespread source of pollution in the Mediterranean Sea • Noise pollution produces a multitude of impacts on marine fish and invertebrates • Marine noise pollution impacts individuals to ecosystems • A variety of measures could be adopted to mitigate marine noise pollution Abstract (max 150 words): Marine noise pollution (MNP) can cause a multitude of impacts on many organisms, but information is often scattered and general outcomes difficult to assess. We systematically reviewed the available knowledgeliterature about MNP impacts on Mediterranean fish and invertebrates. Both chronic and acute MNP produced by several human activities-e.g. maritime traffic, pile driving, air guns-were found to cause detectable effects on intraspecific communication, vital processes, physiology, behavioral patterns, health status and survival. These individual-based effects can extend to induce population-and ecosystem-wide alterations, especially when MNP impacts functionally important species, such as keystone predators and habitat forming species. Curbing the threats of MNP in the Mediterranean Sea is not an easya challenging task, but a variety of measures should could be adopted to mitigate MNP impacts. Successful measures will require more precise accurate information on impacts, and that effective management of MNP actually becomes a priority in the policy makers' agenda.

“…The ocean, including coastal regions, represents a new economic frontier, covering more than two-thirds of the Earth's surface, spanning an increasingly diverse range of activities directed to exploit biological and abiotic resources and space (for traffic, tourism, cable/pipeline connections, energy or aquaculture platforms and waste disposal). The ocean will play a key role in the next decade, particularly in scenarios of accelerated exploitation to fuel a blue great acceleration (Jouffray et al, 2020). Coastal areas present diverse criticalities, ranging from those derived from the extreme effects of climate change to those induced by rapidly increasing anthropic sprawling witnessed in Europe by the presence of half the population within 50 km from the coast and substantially increasing during touristic seasons (Collet and Engelbert, 2017).…”

This article proposes a bioeconomy approach to the management of contaminated sites with the aim to identify actions for the development of a common policy framework for environmental protection and sustainable development. Among the policies addressing pollution on land and at sea, we identify four main gaps that hamper the implementation of measures for the prevention and management of contaminated sites from local to systemic scales. We introduce three concepts from bioeconomy-(i) value-chain, (ii) regional perspective, and (iii) multi-sector approach-that are potentially conducive to socioeconomic and environmental improvement of degraded areas in Europe.
