Abstract Marine ecosystem-based management (EBM) is recognized as the best practice for managing multiple ocean-use sectors, explicitly addressing tradeoffs among them. However, implementation perceived challenging and often slow. A poll of over 150 international EBM experts revealed progress, challenges, solutions in worldwide. Subsequent follow-up discussions with 40 these identified remaining impediments to further EBM: governance; stakeholder engagement; support; uncertainty about...
Abstract The potential effect on surface water pH of emissions SO X and NO from global ship routes is assessed. results indicate that regional reductions the same order magnitude as CO 2 ‐driven acidification can occur in heavily trafficked waters. These findings have important consequences for ocean chemistry, since sulfuric nitric acids formed are strong contrast to weak carbonic acid by dissolution . Our also provide background discussion expanded controls mitigate due these shipping emissions.
In January 2020, new global regulations were implemented to limit the maximum sulphur content in marine fuels. As an alternative switch compliant fuels, allow for installations of exhaust gas cleaning systems, e.g. scrubbers, that enables a continued use less expensive heavy fuel oils (HFOs). Characterization scrubber discharge water shows acidified also becomes enriched with contaminants, and large quantities metals polyaromatic hydrocarbons (PAHs) are thus being discharged directly...
The Baltic Sea is a sensitive environment that affected by chemical pollution derived from multiple natural and anthropogenic sources. overall aim of this study was to estimate the load metals polycyclic aromatic hydrocarbons (PAHs) shipping leisure boating, relative other sources, identify possible measures could lead major reductions in loads hazardous substances maritime boating. use copper-based antifouling paints, operation scrubbers open loop mode, were two most dominant identified...
Abstract In response to stricter regulations on ship air emissions, many shipowners have installed exhaust gas cleaning systems, known as scrubbers, allowing for use of cheap residual heavy fuel oil. Scrubbers produce large volumes acidic and polluted water that is discharged the sea. Due environmental concerns, scrubbers being discussed within International Maritime Organization. Real-world simulations global scrubber-vessel activity, applying actual costs expenses related scrubber...
While shipping has long been recognised as a very carbon-efficient transport medium, there is an increasing focus on its broader environmental consequences. The International Maritime Organisation responsible for the regulation of ship emissions arising from fuel combustion. Their current regulations are, however, much less strict than those applying to land-based within European Union. Five different groups pollutant emission smokestacks are addressed in this paper: sulphur oxides, nitrogen...
Oil spills are serious environmental issues that potentially can cause adverse effects on marine ecosystems. In some areas, like the Baltic Sea, there is a large number of wrecks from first half 20th century, and recent monitoring field work have revealed release oil these wrecks. The risk posed by wreck governed its condition, hazardous substances contained in state surrounding environment. Therefore, need for common standard method estimating risks associated with different this...
Abstract. This paper describes the new developments of Ship Traffic Emission Assessment Model (STEAM) which enable modelling pollutant discharges to water from ships. These include nutrients black/grey as well food waste. Further, contaminants in ballast, black, grey and scrubber water, bilge discharges, stern tube oil leaks are also described releases antifouling paints. Each is regulated by different sections IMO MARPOL convention, emission patterns pollution vary significantly. The...
Marine environmental risk assessments rarely consider the cumulative from multiple contaminants and sources. Ships give rise to a range of contaminants, originating different onboard sources, resulting in contaminant loads marine environment. Here, Ship Traffic Emission Assessment Model (STEAM), combination with hydrodynamic chemical fate model MAMPEC, was used calculate predicted concentrations (PECs) metals polycyclic aromatic hydrocarbons, four ports. PECs were compared no effect (PNEC)...
Shipping is the cornerstone of international trade and thus a critical economic sector. However, ships predominantly use fossil fuels for propulsion electricity generation, which emit greenhouse gases such as carbon dioxide methane, air pollutants particulate matter, sulfur oxides, nitrogen volatile organic compounds. The availability Automatic Information System (AIS) data has helped to improve emission inventories from ship stacks. Recent laboratory, shipborne, satellite modeling studies...
Shipwrecks deteriorate and the probability of a release oil increases with time on sea floor. The potential leakage is risk to marine environment may also have social economic consequences. purpose this study was evaluate existing methods for assessment shipwrecks suggest generic framework. A necessary providing decision support remediation actions thus enabling an efficient use available resources. Existing aimed assessing were evaluated by comparison relevant parts international standard...
Marine pollution management requires identifying all sources of contaminants, yet shipping's role in marine contamination remains unexplored. To address this gap, we investigated shipping contribution to water and air pollutant loads the Northern Adriatic Sea 2018 under two future scenarios. The approach integrated (i) modelled data shipping-related emissions, (ii) load from tributaries, (iii) land-based emissions atmosphere. results showed that significantly contributes copper, zinc (from...
The Baltic Sea is a severely eutrophicated sea-area where intense shipping as an additional nutrient source potential contributor to changes in the ecosystem. impact of two most important shipborne nutrients, nitrogen and phosphorus, on overall nutrient-phytoplankton-oxygen dynamics was determined by using coupled physical biogeochemical model system General Estuarine Transport Model-Ecological Regional Ocean Model (GETM-ERGOM) cascade with Ship Traffic Emission Assessment (STEAM) Community...
Different factors influencing recycling and burial rates of organic carbon (OC) were investigated in the continental margin sediments Skagerrak (NE North Sea). Two different areas, one southern northeastern part visited shortly after a spring bloom (March 1999) late summer (August 2000). Results suggested that: (1) Organic oxidation (C ox ) (2.2-18 mmol C m -2 d -1 generally larger than O 2 uptake (1.9-25 ). Both measured situ using benthic lander. A mean apparent respiration ratio :O 2coor...
International regulation of the emission acidic sulphur and nitrogen oxides from commercial shipping has focused on risks to human health, with little attention paid consequences for marine environment. The introduction stricter regulations in northern Europe led substantial investment scrubbers that absorb a counterflow seawater. This paper examines smokestack scrubber release Baltic Sea according range scenarios coming decades. While is projected become major source strong acid deposition...
An extended suspect screening approach for the comprehensive chemical characterization of scrubber discharge waters from exhaust gas cleaning systems (EGCSs), used to reduce atmospheric shipping emissions sulphur oxides, was developed. The based on chromatography coupled with high-resolution mass spectrometry (GC-HRMS) and focused identification polycyclic aromatic hydrocarbons (PAHs) their alkylated derivatives (alkyl-PAHs), which are among most frequent potentially toxic organic...
Major sources of pollution from shipping to marine environments are antifouling paint residues and discharges bilge, black, grey ballast water scrubber discharge water. The dispersion copper, zinc, naphthalene, pyrene, dibromochloromethane have been studied using the Ship Traffic Emission Assessment Model, General Estuarine Transport Eulerian tracer transport model in Baltic Sea 2012. Annual loads contaminants ranged 10-2 tons for pyrene 100 s copper. is determined by surface kinetic energy...
Shipwrecks around the world contain unknown volumes of hazardous substances which, if discharged, could harm marine environment. can deteriorate for a number reasons, including corrosion and physical impact from trawling other activities, probability leakage increases with time. Before deciding on possible mitigation measures, there are currently few comprehensive methods assessing shipwrecks respect to pollution risks. A holistic method estimating environmental risks should be based...
