One of the world's most endangered whale species could have added protection from threats posed by human marine activity, through technology developed by the University of East Anglia (UEA).

Strathclyde researchers have developed a novel way of measuring underwater noise created by ships which poses a danger to marine life.

- Safety & Shipping Review 2021: 49 large ships lost worldwide last year. Total losses down 50% over 10 years. Number of shipping incidents (2,703) declines year-on-year. - Shipping industry resilient through pandemic, but crew change crisis has long-term consequences. Covid-19 delays and surge in demand for shipping increasing cost of claims. Inadequate ship maintenance could bring future claims. - Suez Canal incident shows ever-increasing vessel sizes continue to pose a disproportionately large risk with costly groundings and salvage operations. High number of fires and containers lost at sea. - South China, Indochina, Indonesia and Philippines maritime region is the global loss hotspot.

When a fire broke out on the deck of the M/V XPress Pearl cargo ship on May 20, 2021, an estimated 70-75 billion pellets of preproduction plastic material, known as nurdles, spilled into the ocean and along the Sri Lankan coastline. That spill of about 1,500 tons of nurdles, many of which were burnt by the fire, has threatened marine life and poses a complex clean-up challenge.

The significant uncertainty and complexity of vessels at sea poses challenges for regulatory bodies in the fishing industry. This paper presents a method for identifying fishing vessel trajectory characteristics involving the Fourier series transform. The model utilizes the FOURIERseries and Gaussian mixture clustering to address the complexity and uncertainty issues in fishing vessel trajectories. First, the vessel trajectories undergo a process of dimensionality expansion and projection along the temporal axis. The relationship between trajectories and complex plane projection was elucidated in this process. Second, a vessel trajectory identification model involving FOURIER transformation was constructed. Subsequently, the phase spectrum was assigned binary values using differentiation, and the phase spectrum characteristics of the transformed trajectories through FOURIER transformation were analyzed. Finally, six encoding formats for fishing vessel motion trajectories in phase spectrum encoding are introduced, along with the determination of uncertain vessel motion range through mixed Gaussian clustering. This method has been validated using a dataset comprising 7,000 fishing vessel trajectories collected from the Beidou satellite positioning system. The results demonstrate that the range of uncertain vessel motion was able to be obtained with the assistance of Gaussian mixture clustering, with an 80% probability position of approximately 1,000 m and a 50% probability position of around 2,000 m. Effective identification of fishing vessel operating and navigational states was achieved, leading to the determination of a safety distance for fishing vessels in the range of 1,000m-2,000 m. This research holds important reference value for fishery regulatory agencies in terms of supervising fishing vessels and maintaining a safe navigational distance.

Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica's pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study.

A major expansion of Europe's offshore wind capacity is on the horizon and Poland wants to be a leading player. The country aims to build 28 GW of new offshore wind capacity by 2050. A new report now finds that the upcoming global shortage of specialised offshore wind vessels might pose a risk for project execution in Poland and worldwide. Poland should see the shortage as an opportunity to build up a fleet of modern vessels to service national and international markets.
