| Measurements at sea during fishing trials on bottom trawl have revealed that the geometry of the trawl is affected by the catch. A series of 37 hauls of around 3 h were carried out during the French EFFICHALUT project. The aim of this project was to carry out improvements on the fishing gear in order to reduce energy consumption. For this project, numerous sensors were used: for bridle tension, door spread, vertical opening, and door attitude. The measurements show quite clearly that the door spread decreases and the bridle tension increases during most of the hauls. The door spread decreased by 1.35 m/h, with a standard deviation of 1.98 m/h while the top bridle tension increased by 47 kg/h, with a standard deviation of 59 kg/h. The mean catch per haul... |

| The remote sensing data which are used by marine fishery forecast only can get the information of ocean surface, while Argo data can provide fishery forecast with temperature and saltinity data of deeper area. To use Argo data in cycle, we need to compute its circle to improve the quality of forecast. In 2001- 2008 , the longer circle was 62.7 days and 117.5 days , and the shorter circle was 4.9 days and 9.8 days, which were obtained by power spectrum estimation. And there was an unobvious circle of 7 days. There existed big changes in observed profile data amount between years and within a year. |

| This review presents a brief analysis and sources (including URLs for the Internet sources) of the most interesting and informative Black Sea oceanographic data sets (excluding satellite data) that are now available for the scientific community with the main attention on the long term data sets. The results of the analysis show that a number of the available Black Sea datasets is growing permanently. However, this process is still rather slow and insufficient. One can hope that new international projects that cover the Black Sea region will drastically improve the situation in nearest years. The attempts should be made as well to create the united reliable quality checked data time series especially for biological data for which long time series do not... |

| IFOP, as non profit marine research institute has the mission to provide to the Under Secretariat of Fisheries in Chile, the technical information and scientific basis for the regulation of Chilean Fisheries. For this purpose it has 150 Scientific Observers distributed throughout the Chilean coast. With the intention to improve the process of data production, a group of scientists has developed a new computer science system for data collection, data management, and automatic publication of fishing and biological indicators in Web Page. The system allow to collect data of: fishing trips; captures and species composition; length distribution and biological variables. For this is being carried out the following process. Collection of data in Pocket PC with... |

| This study investigates how the lionfish (Pterois sp.) invasion of the Western Atlantic Ocean has been socially constructed by natural scientists, the media, and stakeholders associated with various marine protected areas in the Caribbean. By examining the use of data and metaphors by these actors, I identify where invasion discourses converge and diverge. Although consensus exists regarding the non-nativeness, introduction vector, and successful establishment of lionfish throughout the region, I also identify uncertainty surrounding lionfish impact and controversies regarding lionfish management and control. The dominant discourse frames lionfish as a threat and control efforts as a war to keep the enemy at bay, and promotes lionfish hunting and... |

| After a brief reminder on general concepts used in data cataloguing activities, this chapter provides information concerning the architecture and design recommendations for the implementation of catalogue systems for the ENVRIplus community. The main objective of this catalogue is to offer a unified discovery service allowing cross-disciplinary search and access to data collections coming from Research Infrastructures (RIs). This catalogue focuses on metadata with a coarse level of granularity. It was decided to offer metadata representing different types of dataset series. Only metadata for so-called flagship products (as defined by each community) are covered by the scope of this catalogue. The data collections remain within each RI. For RIs, the aim is... |

| Data formatting is an important component of data Management technologies, which provides the structural basis for data sets ‘ creation as well as for software interfaces between data sets and procedures of data processing, analysis, visualization and dissemination. Data formatting is of particular importance for data exchange between subject - oriented technologies, between data centres, between a data centre and users. For a long time the Group of Experts on Technical Aspects of Data Exchange (IODE GETADE) has been responsible for providing the standardization of ocean data exchange. These activities resulted in development of the General Format (GF3) formatting system and, the GF3 subsets for various disciplines (oceanography,... |

| It is very important to work with data, information and knowledge correctly, when a decision model is used as a support for managerial decision-making. Unfortunately, these terms are understood differently in various branches; particularly, the definitions of knowledge are very different. It causes problems in praxis; it is not clear, in which case data processing, information or knowledge/expert systems are appropriate to use. In this paper we introduce modern approaches to indentifying these terms. The objective of the paper is to identify data, information and knowledge in decision-making process, particularly in multiple-criteria decision-making model, to help users of such models to better understand it. To reach this objective, we need to provide... |

| This paper traces the evolution of space-derived remote sensing data and data products from their initial dissemination to their impact on public policy related to climate change. We focus on the examples of renewable energy, public health, and ecosystem assessment. Our approach differs from previous studies that have characterized the value of data in terms of the fundamental scientific phenomena they describe. In our research we have sought to identify contributions of space-derived earth science in "making a difference" beyond scientific understanding, thereby providing at least a partial answer to questions about the utility of research posed by Congress, the Office of Management and Budget, managers at the National Aeronautics and Space... |

| Data are currently being used, and reused, in ecological research at an unprecedented rate. To ensure appropriate reuse however, we need to ask the question: “Are aggregated databases currently providing the right information to enable effective and unbiased reuse?” We investigate this question, with a focus on designs that purposefully favour the selection of sampling locations (upweighting the probability of selection of some locations). These designs are common and examples are those designs that have uneven inclusion probabilities or are stratified. We perform a simulation experiment by creating datasets with progressively more uneven inclusion probabilities, and examine the resulting estimates of the average number of individuals per unit area... |

| The GODAR Workshop for IOC Member States of the Caribbean and South America held at Cartagena, Colombia was the fifth in the series after 4 held at: Obninsk Russian Federation (17-20 May 1993) for Member States of Central and Eastern Europe; Tianjin, China (8-l 1 March 1994) for Member States of WESTPAC; Dona Paula, Goa, India (6-9 December 1994) for Member States of the Indian Ocean and Malta (25-28 April 1995) for Member States of the Mediterranean Sea. The purpose of the current Workshop was to identify relevant data in the region and to consider the steps necessary to make this data available to the wide international marine science community thus adding to the global oceanographic data archive. These archives are valuable for different fields of... |
