The International Maritime Organization (IMO) has adopted an action plan to enhance existing regulations and introduce new supporting measures to reduce marine plastic litter from ships. Discharging plastics into the sea is already prohibited under regulations for the prevention of pollution by garbage from ships in the International Convention for the Prevention of Pollution from Ships (MARPOL), which also obliges governments to ensure adequate port reception facilities to receive ship waste. Recognizing that more needs to be done to address the environmental and health problems posed by marine plastic litter, IMO member states agreed on actions to be completed by 2025, which relate to all ships, including fishing vessels. The action plan supports IMO's commitment to meeting the targets set in the UN 2030 Sustainable Development Goal 14 on the oceans. Measures include a proposed study on marine plastic litter from ships, enhancing public awareness and strengthening interna- tional cooperation. )) Seabed 2030 Project Advances. The first regional mapping meeting for The Nippon Foundation-GEBCO Seabed 2030 Project was held in Stockholm, covering the Arctic, Antarctic and North Pacific regions. The successful meet- ing brought together leading ocean-mapping experts, oceanographers, scientists and private companies to discuss technical elements, including data acquisition, visualization, expedition coordination and the role of future tech- nologies. With the goal of mapping the entirety of the world's ocean floor by 2030, the project divides responsibility for different areas of the ocean between four centers, located at the Alfred Wegener Institute, Germany, covering the Southern Ocean; the National Institute of Water and Atmospheric Research, New Zealand, covering the South and West Pacific Ocean; the Lamont-Doherty Earth Observatory, Columbia University, U.S., covering the Atlantic and Indian Oceans; and Stockholm University, Sweden, in partnership with the University of New Hampshire, U.S., for the Arctic and North Pacific Ocean. Regional products are fed to the Global Data and Coordination Centre hosted at the British Oceanographic Centre in the U.K. The meeting identified numerous sources of new bathymetric data. )) Subsea Market Rebounding. The Westwood's Subsea Vessels Operations & Hardware Market Forecast 2019 to 2023 report reveals that the subsea market is showing signs of recovery. The recovery in oil prices to above $70/ bbl continues to spur a new wave of offshore investment. Westwood is forecasting a rebound in offshore activity, with subsea vessel operations and hardware expenditure expected to amount to $152 billion over 2019 to 2023. The recovery in the subsea market has significantly supported project sanctioning, with the number of greenfield projects passing the final investment decision stage in 2018, increasing by 154 percent compared with 2016, at the low point of the downturn. This is supported by positive macro drivers in the near and long term, albeit the recovery remains dependent on geopolitics and OPEC. Supply-chain conditions remain challenging, and despite the strength of free-cash flow to operators, this has not yet translated to an improved commercial environment for services and equipment. Operators are also managing their risk exposure through phased developments and standardized solu- tions for equipment. )) Hurtigruten to Power Vessels with Dead Fish. Cutaways from fisheries and other organic waste will soon be used to power Hurtigruten's fleet of green cruise ships. With a growing fleet of 17 ships, Hurtigruten is the world's largest expedition cruise line. The company has invested heavily in green technology, including fueling ships with liquefied biogas (LBG), which is fossil-free, renewable gas produced from dead fish and other organic waste. By 2021, Hurti- gruten plans to operate at least six of its ships on a combination of biogas, LNG and large battery packs. )) AUV Sonar Supports San Juan Search. EdgeTech's side scan sonar technology was used to help find the miss- ing Argentine submarine ARA San Juan. The deepwater search was performed by Ocean Infinity and its fleet of 6,000-m-rated AUVs equipped with the sonar. The San Juan was imaged by the sonar operating at a frequency of 230 kHz and a 400-m-range scale. The submarine had been missing for a year before being discovered in more than 900 m of water. )) Live Broadcast from Belize Sinkhole. The Blue Hole Belize Expedition 2018 fleet went on a historic and scientif- ically important three-week mission to map the world's largest marine sinkhole. Led by Aquatica Submarines, the team of scientists, explorers and film makers included Ocean Unite co-founder and Virgin Group founder Sir Rich- ard Branson and oceanographic explorer and documentary filmmaker Fabien Cousteau, grandson of the pioneering conservationist Jacques Cousteau. A live broadcast from deep inside the blue hole took place in Aquatica's Stingray 500 submarine in December on Discovery Channel with Branson and Cousteau on board. Sonar expert Mark Ath- erton from Kongsberg Mesotech was a key member of the science-based sonar and scientific data collection team. He operated Kongsberg sonars aboard a research vessel, contributing to an invaluable high-resolution map of the entire sinkhole. The expedition aids understanding of the geological history and geometric structure of the blue hole, which contributes new data to the global scientific community studying sinkholes and cenotes. ST
