Nanyang Technological University, Singapore (NTU Singapore) today launched a new marine research laboratory to develop innovative eco-friendly technologies for Singapore's maritime and offshore industry Nanyang Technological University, Singapore (NTU Singapore) today launched a new marine research laboratory to develop innovative eco-friendly technologies for Singapore's maritime and offshore industry. The Sembcorp Marine Lab at NTU, named in appreciation of a $10 million endowment fund set up by Sembcorp Marine, aims to develop ground-breaking solutions in fuel emission management, energy efficiency, and green shipping. It is equipped with the Southeast Asia's first dual-fuel marine engine, which is supported by the Singapore Economic Development Board (EDB). NTU researchers will study ways to retrofit ships to operate using two fuel types simultaneously - one of it being clean fuel - in a bid to reduce harmful emissions while keeping costs low. Such solutions are also aimed at delivering competitive advantages, and help shipping companies better prepare for the stringent emission regulations that will come into effect in 2020. NTU Provost Professor Freddy Boey, said, "A global university with recognised strengths in sustainability research, NTU can play an important role in developing innovative eco-friendly technologies for Singapore's marine and offshore industry. "Our partnership with SembCorp Marine and the Singapore Economic Development Board combines our strengths and creates fresh synergies, allowing the lab to carry out cutting-edge research in fuel emission management, energy efficiency, and green shipping." Mr Tan Kong Hwee, Director for Transport Engineering at the EDB said, "NTU's focus on developing greener marine technologies is testament to the increasing interest in sustainable solutions for the marine and offshore engineering (M&OE) sector. The lab will also demonstrate Singapore's capabilities in industry-relevant M&OE research." The lab was officially opened this morning by Mr Wong Weng Sun, President & Chief Executive Officer, Sembcorp Marine. "With the opening of the Sembcorp Marine Lab @ NTU, the offshore and marine sector now has a new research venue for investigating eco-friendly energy solutions, including clean and renewable fuels for marine engines, and emission control technologies," Mr Wong said. "I am excited about the lab's potential and look forward to a close collaboration between Sembcorp Marine and NTU to drive the R&D activities forward." Overhauling ships to operate entirely on alternative or clean fuels is a costly endeavour as it requires a complete overhaul of the engine systems. To keep costs low, the Sembcorp Marine Lab at NTU will find ways to retrofit and modify ship systems to operate using both diesel and a clean fuel such as liquefied natural gas (LNG). Researchers will also study the emission levels of various clean fuels and the viability of using biofuels such as biodiesel in ship engines. These solutions will provide simpler and cheaper options for ship companies to go green and ensure that ships' emission levels comply with international standards. Professor Lua Aik Chong, Acting Executive Director of Maritime Institute @ NTU and professor-in-charge of the new lab, said, "This lab comes at an important time amid rising energy demands and environmental concerns about carbon emissions and global warming. With international bodies already taking action, the lab will help the industry prepare for the changes, by providing viable and cost effective solutions." The new lab will also serve as a testbed, and work with various industry partners and government agencies such as the Maritime and Port Authority of Singapore (MPA) on maritime-related research projects. A research-intensive public university, Nanyang Technological University, Singapore (NTU Singapore) has 33,500 undergraduate and postgraduate students in the colleges of Engineering, Business, Science, Humanities, Arts, & Social Sciences, and its Interdisciplinary Graduate School. It has a new medical school, the Lee Kong Chian School of Medicine, set up jointly with Imperial College London. NTU is also home to world-class autonomous institutes - the National Institute of Education, S Rajaratnam School of International Studies, Earth Observatory of Singapore, and Singapore Centre for Environmental Life Sciences Engineering - and various leading research centres such as the Nanyang Environment & Water Research Institute (NEWRI), Energy Research Institute @ NTU (ERI@N) and the Institute on Asian Consumer Insight (ACI). Ranked 13th in the world, NTU has also been ranked the world's top young university for the last two years running. The University's main campus has been named one of the Top 15 Most Beautiful in the World. NTU also has a campus in Novena, Singapore's medical district.

Sea transport is increasing due to its environmental and economic benefits. The related expansion of ports and the development towards longer, wider and more deep-draught ships cause a huge need for dredging of sediments in fairways and ports. A large volume of these sediments are contaminated with heavy metals and organic contaminants. Millions of m3 of these sediments have to be dredged and handled in the coming years according to studies performed by the SMOCS/PortInfra network. The SMOCS project (Sustainable Management of Contaminated Sediments) within the Baltic Sea Region Programme 2007-2013 has developed a guideline on management of contaminated sediments based on a sustainability approach. This paper deals with important considerations and key experiences in the different phases in a project from characterisation of sediments to be dredged, basic risk assessment, feasibility study and selection of handling options, planning and permitting, execution incl. detailed design considerations and field test and serviceability stage incl. monitoring. The stabilization/solidification technology has been applied implying the beneficial use of such treated dredged contaminated sediments in port constructions reducing the use of natural resources. © The authors and ICE Publishing: All rights reserved, 2015.

The paper presents the results of toxicity determinations carried out on sediment samples collected in the vicinity of the wreck of the German s/s Stuttgart (the southern part of the Gulf of Gdańsk, off the Polish coast) in relation to the determination of polycyclic aromatic hydrocarbons (PAHs). The toxicity of surface and core sediment samples was assessed using two biotest organisms - the bioluminescent bacteria Vibrio fischeri and the ostracod Heterocypris incongruens. PAH levels in these samples were determined by GC-MS. The surface sediments collected at W2 (ca. 34 m north of the shipwreck) and W4 (ca. 415 m north-east of the wreck) as well as the core sediments collected at WR3 (ca. 400 m north-east of the wreck) were the most heavily polluted with substances toxic to the biotest organisms. The chronic and acute toxicities in the case of most of the surface sediment samples studied are correlated. This may suggest that not only hydrophobic chemicals (like PAHs from fuel residues) but also more polar chemicals (resulting from the conversion of aromatic hydrocarbons) are responsible for the toxicity levels found. There is a clear dependence between the levels of chronic toxicity and PAH concentrations in the core sediment samples. In addition, a simultaneous decrease in the PAH content and chronic toxicity was noted in all the core sediment samples at depths below 80 cm. © 2012 The Royal Society of Chemistry.

Basing on results of detailed hydroacoustic research, the geological structure of the bottom to 20-22 m b.s.l. has been studied. The palaeo-Slupia palaeo-valley, buried bya thin cover of marine sands, has been recognized and determined. Some stages of valley development may be distinguished. The deposits of the oldest valley are C14 dated at ca. 21 ka BP. But in the main stage, the valley was formed by action of the subglacial and thawing glacial waters during and after the so-called Gardno Phase. Most probably this valley was connected with the Pomeranian ice margin valley. The next stages ofthe valley's development were related with changes of the palaeo-Slupia under conditionsof the Litorina transgression. The youngest palaeo-Slupia valley is, in the authors' opinion, related with a shallow, long incision, weakly marked in the sea bottom in the central part of the studied area. Field investigations were carried out by the Department ofOperational Oceanography of the Maritime Institute in Gdalsk from the r/v Dr Lubecki. A DESO 15 echosounder, Subbottom Profilers model 3010 and the X Star system were used. Eight vibrocores (core length up to 3 m) were taken from the sea bottom and three borings (10-17 m depth) were executed on the shore. Accurate positioning was obtained using the DGPS and HYDRO and Track Point Systems. All data were digitally recorded and processed.

The present study applies an evolutionary resilience framework to complex socioecological systems in the coastal regions in Europe with a particular focus on lagoons. Despite their variations, lagoons share common challenges in achieving effective and sustainable ways of governing and managing economic, social, and environmental uncertainties. Our aim is to demonstrate that building resilience involves planning not only for recovery from shocks but also for cultivating preparedness and seeking potential transformative opportunities that emerge from change. The framework consists of 4 dimensions: persistence, adaptability, transformability, and preparedness. To illustrate how this 4-dimensional framework can be applied to the specific context of lagoons, we draw on examples of good and poor practices from the 10 lagoons studied as part of the ARCH project.

This manuscript is a continuation of the results presented in the earlier work by Dzierzbicka-Głowacka et al. (2013). Major purpose of this study is to characterize population dynamics of three major Baltic calanoid copepod species (Acartia spp., Temora longicornis and Pseudocalanus sp.) in the Gulf of Gdańsk during the years 2006-2007. This paper focuses mostly on biomass estimation, production and mortality rates. All three species had the highest observed biomass in summer 2007 and it was 12.62, 9.16 and 0.80 mg C m-3 for Acartia spp., T. longicornis and Pseudocalanus sp., respectively, while highest daily production rates for those species were 28.22, 18.47, 1.34 mg C m-2, all recorded in summer 2007. Mortality rates were calculated for all copepodite stages of selected species, and in most cases highest values were observed during summer seasons. © 2014 Institute of Oceanology of the Polish Academy of Sciences.

In Mediterranean seas and coastal zones, rivers can be the main source of mercury (Hg). Catchment management therefore affects the load of Hg reaching the sea with surface runoff. The major freshwater inflows to the Baltic Sea consist of large rivers. However, their systems are complex and identification of factors affecting the outflow of Hg from its catchments is difficult. For this reason, a study into the impact of watershed land use and season on mercury biogeochemistry and transport in rivers was performed along two small rivers which may be considered typical of the southern Baltic region. Neither of these rivers are currently impacted by industrial effluents, thus allowing assessment of the influence of catchment terrain and season on Hg geochemistry. The study was performed between June 2008 and May 2009 at 13 sampling points situated at different terrain types within the catchments (forest, wetland, agriculture and urban). Hg analyses were conducted by CVAFS. Arable land erosion was found to be an important source of Hg to the aquatic system, similar to urban areas. Furthermore, inflows of untreated storm water discharge resulted in a fivefold increase of Hg concentration in the rivers. The highest Hg concentration in the urban runoff was observed with the greatest amount of precipitation during summer. Moderate rainfalls enhance the inflow of bioavailable dissolved mercury into water bodies. Despite the lack of industrial effluents entering the rivers directly, the sub-catchments with anthropogenic land use were important sources of Hg in the rivers. This was caused by elution of metal, deposited in soils over the past decades, into the rivers. The obtained results are especially important in the light of recent environmental conscience regulations, enforcing the decrease of pollution by Baltic countries. © 2014, The Author(s).

The study presents changes in the total development time of Copepoda species, i.e. Pseudocalanus sp., Temora longicornis and Acartia spp. occurring in large numbers in the Southern Baltic Sea. The following factors were taken into account: temperature, salinity and concentration of food. The presented research involved simulations with greenhouse gas emissions scenarios A1B and B1. The analysis was performed for naupliar and copepodid stages combined together, and the results present the total development time of organisms from the naupliar stage to the adult form. The calculations were carried out using numerical methods based on the experimental data available in the literature. © 2016 Faculty of Oceanography and Geography, University of Gdañsk, Poland.

This article deals with the legal and practical recommendations for the management of dredged material in the riparian countries of the Baltic Sea. The recommendations are contained in three conventions: LC, 2000. London Convention (1972), Convention on the Protection of the Marine Environment of the Baltic Sea area (Helsinki Convention) (1992), the OSPAR Convention (1972). Different approaches to evaluating the contamination level of dredge spoils, used by the Baltic Sea riparian countries, have been characterized. The differences in those approaches manifest themselves by various concentration limits for contaminants, which form a basis for the classification of dredged material as either contaminated or non-contaminated, and thus determine how the spoils will be processed further. Based on the collected information about the concentration limits for contaminants of surface sediments in the coastal ports, it was pointed out that it is necessary to conduct routine monitoring of heavy metals, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, tributyltin, and petroleum hydrocarbons in dredged sediments in all the Baltic Sea states. On the other hand, the monitoring of polychlorinated dibenzo-p-dioxins/furans, organochlorine, and organophosphoric pesticides is only needed in locations that are suspected of historical or being the local contamination sources. Due to significant economic limitations of chemical determinations, it is important to consider a simple screening test of sediment that would say whether sediment may be contaminated and qualifies for more detailed and costly chemical research. It may be typical basic physical-chemical analysis of sediments or ecotoxicological classification of sediments.Despite environmentally friendly tendencies, the practical application of dredged material within the Baltic Sea area is very limited. Dredged material is most frequently stored at the specifically designated sites. From among the practical uses of dredge spoils, beach nourishment is of the highest significance.In the conclusion, the new proposed management procedure of dredged material was presented.
