| The Fukushima nuclear accident resulted in the largest ever accidental release of artificial radionuclides in coastal waters. This accident has shown the importance of marine assessment capabilities for emergency response and the need to develop tools for adequately predicting the evolution and potential impact of radioactive releases to the marine environment. The French Institute for Radiological Protection and Nuclear Safety (IRSN) equips its emergency response centre with operational tools to assist experts and decision makers in the event of accidental atmospheric releases and contamination of the terrestrial environment. The on-going project aims to develop tools for the management of marine contamination events in French coastal areas. This should... |

| In 2009, following approval of the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission (EC) created task groups to develop guidance for eleven quality descriptors that form the basis for evaluating ecosystem function. The objective was to provide European countries with practical guidelines for implementing the MSFD, and to produce a Commission Decision that encapsulated key points of the work in a legal framework. This paper presents a review of work carried out by the eutrophication task group, and reports our main findings to the scientific community. On the basis of an operational, management-oriented definition, we discuss the main methodologies that could be used for coastal and marine eutrophication assessment.... |

| A new sand-dwelling dinoflagellate species, Cabra reticulata sp. nov., is described from sandy habitats in the south of Brittany (northwestern France). This new species possesses the characteristics of the 'unusual' genus, Cabra Murray et Patterson. The thecal plate formula is Po Pt 3' 1a 4'' 'x' 3c ?s 5''' 1'''' (or alternatively interpreted as Po Pt 4' 0a 4'' 'x' 3c ?s 5''' 1''''). Because of the strong lateral compression, cells of C. reticulata are frequently seen laterally and have a polygonal shape, with three prominent antapical pointed flanges and a dorsal spine in the anterior part of the hypotheca. The cingulum is ascending and incomplete. The thecal surface is ornamented with strong reticulations forming polygonal areolae, which differs from C.... |

| Polyurethanes are frequently used in underwater applications. They are required to resist the marine environment over long periods of immersion but the multiplicity of resin formulations makes material selection difficult. Accelerated tests are essential to guarantee long term integrity. This paper presents results from an experimental study in which polyurethane samples of two hardnesses, 40 and 90 Shore A, have been subjected to immersion in artificial sea water for periods up to two years at temperatures from 50 to 100 degrees C. In parallel samples have been immersed at sea in the Brest Estuary for up to five years. Mechanical properties have been measured on tensile specimens after ageing. The accelerated test results and FTIR analysis indicate that... |

| Oligonucleotide probes are increasingly being used to characterize natural microbial assemblages by Tyramide Signal Amplification-Fluorescent in situ Hybridization (TSA-FISH, or CAtalysed Reporter Deposition CARD-FISH). In view of the fast-growing rRNA databases, we re-evaluated the in silico specificity of eleven bacterial and eukaryotic probes and competitor frequently used for the quantification of marine picoplankton. We performed tests on cell cultures to decrease the risk for non-specific hybridization, before they are used on environmental samples. The probes were confronted to recent databases and hybridization conditions were tested against target strains matching perfectly with the probes, and against the closest non-target strains presenting one... |

| As most of the sea bottom in the Dutch part of the North Sea consists of sand, marine fauna that live in association with hard substrates are rarely monitored. We report here on the results of a species inventory in June 2011 done by scuba-diving while focusing on a wreck on the Dogger Bank and on rocky bottoms on the Cleaver Bank. This resulted in various new records of species for the Dutch part of the North Sea. This result appeared for a large part linked to the added value of monitoring with scuba-divers. It is therefore concluded that scuba-divers should be used in addition to the more traditional monitoring methods in which dredges and grabs are used, if one aims at getting an accurate view of the biodiversity present in marine regions like the... |

| The relative sensitivities of 309 common invertebrate species in Dutch marine waters are presented for environmental and anthropogenic pressures like organic enrichment, sedimentation and fisheries. The species were furthermore appointed to trophic groups like suspension and deposit feeders. The Dutch Ministry of Infrastructure and the Environment uses these data when calculating the Benthic Ecosystem Quality Index 2 and the Infaunal Trophic Index. These metrics aid in the mandatory monitoring of ecological quality for example for the European Water Framework Directive. The common Dutch species were selected based on their abundance according to, 1. the mwtl dataset including results of on-going monitoring programs issued by the Ministry, 2. the... |

| Open ocean zooplankton often have been viewed as slowly evolving species that have limited capacity to respond adaptively to changing ocean conditions. Hence, attention has focused on the ecological responses of zooplankton to current global change, including range shifts and changing phenology. Here, we argue that zooplankton also are well poised for evolutionary responses to global change. We present theoretical arguments that suggest plankton species may respond rapidly to selection on mildly beneficial mutations due to exceptionally large population size, and consider the circumstantial evidence that supports our inference that selection may be particularly important for these species. We also review all primary population genetic studies of open ocean... |

| The Training Course on Management of Marine Data and Information for the IOCINCWIO Region was held in Mombasa, Kenya, from 1 to 11 December, 1997. The Course was organized in cooperation with and kindly hosted by the Kenya Marine and Fisheries Research Institute, Mombasa. The course was designed within the continuing training programme of the IODE to familiarize marine data and information managers with current procedures and methods related to marine data and information management, with a special emphasis on newest microcomputer methods and software. Through such training courses the IOC aims to ensure increasing and sustained collaboration of Member States in the IODE programme, and to maintain a high level of competence in the National Oceanographic... |

| From the perspective of low carbon economy, the paper analyzes the factors that influencing the development of low carbon economy. It is showed that the damage of marine ecological environment results in the low ability of oceans in absorbing green gas; environmental pollution leads to lowering capacity of ocean to deal with the wastes; development of related marine industries brings deterioration of marine environment; changes of climate threat the healthy development of marine economy. The paper points out the development routines of marine low carbon economy: accelerating the innovation of energy techniques, exploring marine renewable green energies; planning scientifically and strengthening the protection and repairmen of marine environment; developing... |
