| A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. <i>In situ</i> measurements of cloud drop size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside-cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to remotely sensed measurements of cloud radiative properties. The authors examine the processes behind ship track formation in a polluted marine boundary layer as an example of the effects of anthropogenic particulate pollution on the albedo of marine stratiform clouds. |

| New coastal and marine management strategies have recently been developed in many countries and regions. From an ecosystem approach perspective, the aim of such strategies is the maintenance of ecosystem integrity while enabling the sustainable use of ecosystem goods and services. There is, however, a need for harmonized definitions and standardized processes to deal not only with the interjurisdictional and multidisciplinary complexities that are associated with such strategies but also with the extensive timelines and resources implicated in the planning and implementation of these strategies. The ecosystem-based management system proposed here is based on three pillars that facilitate the integration of an ecosystem approach to coastal and oceans policy... |

| This first issue is devoted to the use of indicators for ICAM, and is a direct result of the IOC-DFO-NOAA-CSMP International Workshop on the same topic, organised in May 2002, in Ottawa. Based on a background paper prepared by the Center for the Study of Marine Policy (University of Delaware) in preparation for the workshop, the aim of this Reference Guide is to present a literature review on the use of indicators around the world, from various programmes and projects, at global, regional, national and local scale.The need for indicators and reporting techniques which reflects the performance of coastal management projects and programmes and reveals the complex relationship that exist between coastal ecosystem health and anthropogenic activities,... |

| Ha sido demostrado, por otros autores, que el alga Ulva fasciata Delile posee una actividad antioxidante promisoria y en el presente trabajo evaluamos si la actividad antioxidante de muestras de esta alga puede ser influenciada por la adsorción de metales, pesados y otros por parte del alga. U. fasciata fue colectada en tres zonas de las costas de la Ciudad de la Habana que presentan diferentes niveles de eutrofización: 1) la desembocadura del Río Quibú, un río que atraviesa una importante zona industrial de la capital cubana y en la cual la concentración de metales acumulados por el alga fue mayor; 2) la zona del Malecón habanero, que recibe la contaminación de la bahía de la Habana y del Río Almendares pero no de forma directa, donde presentó valores... |

| En la Colección de Bacterias Marinas se conservan aislamientos procedentes de diferentes regiones del archipiélago cubano. Aquí se desarrollan actividades de investigación y servicios, entre las primeras se encuentran los estudios para la conservación de las cepas a mediano y largo plazo, la determinación taxonómica de sus componentes, la evaluación de bioactividades con aplicación en la industria médico-farmacéutica y en el saneamiento ambiental y la actualización de la base de datos asociada. Entre las actividades de servicios se encuentran el mantenimiento y caracterización de las cepas, así como el suministro a los usuarios. |

| Data obtained by observers on board of two fishing vessels during six trips carried out between January-April 2010 to catch tuna were analyzed. Thirty-four fishing days were completed and of the 59 trawls performed 37 turned out positive (with tuna catches). The fishing gear consisted of a purse seine net. Exploitation took place within the Argentine-Uruguayan Common Fishing Zone, between 36° S-39° S. The main landings occurred in March and consisted of slender tuna, Allothunnus fallai (57%), followed by albacore, Thunnus alalunga (28.5%), in January and bonito, Sarda sarda (14%), in April. Sea surface temperature ranged 16 °C-19 °C. A total of 25 length frequency samples allowed to measure individuals of the species above mentioned and those of skipjack... |

| The Red Sea and Gulf of Aden (Figure 1.1) constitute a unique ecosystem with high biological diversity. Their natural resources provide a substantial economic support for the region: in addition to the fishery industry, which has ensured food security to many people of the region and created jobs for others, tourism is an ever growing and increasingly important industry for commerce and other economic activities. Hence, the marine environment should be well protected from the adverse impacts of pollution to ensure the sustainable use of its resources and good health of its users. Continuous degradation of the marine environment poses a threat to public health through the contamination of seafood, direct contact and digestion of polluted water. Damage to... |

| Se estudia la biología y ecología reproductiva de las ocho especies de Bathyraja presentes en la plataforma continental argentina (Atlántico S.O.), a través del análisis del tamaño corporal, las cápsulas de huevos, el desarrollo de los embriones, la talla de madurez sexual, las variaciones en las condiciones reproductivas, las áreas de puesta y la segregación espacial de los individuos. El material examinado provino de campañas de investigación llevadas a cabo por el Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) entre 34º40'S y 54º30'S, desde septiembre 2003 hasta octubre 2007. La información presentada en el trabajo demuestra que las especies del Género Bathyraja en la plataforma argentina maduran a una talla alta en relación a la Lt... |

| Con el objetivo de determinar la factibilidad de reactivar la ostricultura al Norte de Villa Clara, Cuba, se realizaron dos cruceros de investigación en febrero y mayo de 2006, meses de seca y lluvia respectivamente. La temperatura del agua presentó valores entre 24,8 y 28,8˚ C; la salinidad mostró valores extremos entre 37 y 39,5; el oxígeno disuelto entre 4,62 y 6,34 mg/L; la transparencia del agua de 45 a 90%; la demanda química de oxígeno presentó extremos entre 1.48 y 3.84 mg/L, y el pH entre 7,98 y 8,28. El fitoplancton presentó variaciones espaciales entre las concentraciones de células de 0,2 a 0,9 x 106 cel/L, siendo las diatomeas el grupo más representativo; el género que mayor abundancia presentó fue Pseudonitzschia sp. A partir de... |

| Results of the investigation carried out in Lakes Mariut and Edku revealed that the trace metals concentrations in ceratophyllum demersum is relatively higher than that in Potamogeton pectinatus. The protein and trace metals in macrophytes collected from unpolluted areas is lower thjan that form polluted ones. Eichhornia crassipes can have a restricted role for the treatment of lake water. In Lake Edku, the results of chemical composition of sediments agree with the previous studies. The trace metal content of C. demersum was higher than that of P. pectinatus. The higher organic carbon level was recorded in stems of submerged plants and in leaves of floating ones. On the other hand, the high concentration of trace metal was observed in leaves of submerged... |

| Using time series analyses, some physical parameters of the continental shelf waters of the Gulf of Guinea were examined. Analysis of coastal sea surface temperatures from Ghana and Ivory Coast, and offshore sea surface temperatures from the Gulf of Guinea clearly shows spatial and inter-annual patterns of cooling in coastal waters of West Africa. The behaviour of the decomposed trend of coastal and offshore sea surface temperatures, sub-surface: temperature measured at 100 m depth off Ghana and salinity showed that the observational period (1963-1992) could be divided into three climatic periods: the period before 1972, from 1972 to 1982, and the period after 1982. In the first period, sea surface temperature at both coastal and offshore areas and bottom... |
