Navigating through SPASE to heliospheric and magnetospheric data

Virtual observatories have been introduced by the astrophysics community as an environment connecting distributed data sources with a unified interface. The heliophysics community soon recognized that they faced a similar problem of many distributed data sets with varying amount of information about them and several discipline specific virtual observatories have been established. Two of them, the virtual heliospheric observatory (VHO) and the virtual magnetospheric observatory (VMO), share a common architecture design with development efforts oriented towards a structured data search. This paper describes the VHO/VMO middleware and its components from metadata preparation and processing to the user interface.     

Virtual observatories for space and solar physics research

As soon as the first data became available online over the Internet, it was obvious that different sites holding related datasets should appear to the end user as a single data system, even if the data itself is stored at multiple locations. To achieve this objective in the context of continuing parallel development of multiple data centres, in 2003 several actors in the realm of space plasmas created the international consortium Space Physics Archive Search and Extract (SPASE). Since 2005 US participation in SPASE has been supported by NASA, and early in 2006 NASA funded five new Virtual Observatories to cater for different aspects of solar system plasma science. This paper outlines the current status of the SPASE effort, the opportunities it offers, its specificities with respect to other parts of the astronomical virtual observatory, and the possibilities it offers for space weather.

High precision analysis of an embryonic extensional fault-related fold using 3D orthorectified virtual outcrops: The viewpoint importance in structural geology

Image-based 3D modeling has recently opened the way to the use of virtual outcrop models in geology. An intriguing application of this method involves the production of orthorectified images of outcrops using almost any user-defined point of view, so that photorealistic cross-sections suitable for numerous geological purposes and measurements can be easily generated. These purposes include the accurate quantitative analysis of fault-fold relationships starting from imperfectly oriented and partly inaccessible real outcrops. We applied the method of image-based 3D modeling and orthorectification to a case study from the northern Apennines, Italy, where an incipient extensional fault affecting well-layered limestones is exposed on a 10-m-high barely accessible cliff. Through a few simple steps, we constructed a high-quality image-based 3D model of the outcrop. In the model, we made a series of measurements including fault and bedding attitudes, which allowed us to derive the bedding-fault intersection direction. We then used this direction as viewpoint to obtain a distortion-free photorealistic cross-section, on which we measured bed dips and thicknesses as well as fault stratigraphic separations. These measurements allowed us to identify a slight difference (i.e. only 0.5°) between the hangingwall and footwall cutoff angles. We show that the hangingwall strain required to compensate the upward-decreasing displacement of the fault was accommodated by this 0.5° rotation (i.e. folding) and coeval 0.8% thickening of strata in the hangingwall relatively to footwall strata. This evidence is consistent with trishear fault-propagation folding. Our results emphasize the viewpoint importance in structural geology and therefore the potential of using orthorectified virtual outcrops.

Dynamic data integration for structural modeling: model screening approach using a distance-based model parameterization

This paper proposes a novel history-matching method where reservoir structure is inverted from dynamic fluid flow response. The proposed workflow consists of searching for models that match production history from a large set of prior structural model realizations. This prior set represents the reservoir structural uncertainty because of interpretation uncertainty on seismic sections. To make such a search effective, we introduce a parameter space defined with a “similarity distance” for accommodating this large set of realizations. The inverse solutions are found using a stochastic search method. Realistic reservoir examples are presented to prove the applicability of the proposed method.

New discoveries in dynamics of an M8 earthquake-phenomena and their implications from the 2003 Tokachi-oki earthquake using a long term monitoring cabled observatory

At the 2003 Tokachi-oki earthquake of M8, seafloor phenomena such as a generation process of tsunami, seafloor uplifts, turbidity current, etc., were observed using a cabled observatory installed on the seafloor. The turbidity current was observed as a benthic storm caused presumably by the mainshock. The seafloor uplifts were observed at the mainshock and continuously after the mainshock. The uplifts were 0.35, 0.37, and 0.12 m for epicentral distances of 25.5, 31.4, and 81.7 km, respectively. After the mainshock, a continuous uplift of the seafloor is observed at all three pressure gauge locations indicating that there was a change in the state of friction on the plate boundary interface by the mainshock. In this paper, we first show what was observed using the cabled observatory installed right above the focal area of the earthquake, and then we discuss to summarize these phenomena associated with the earthquake, its possible causes, and future directions in long term monitoring of seismogenic processes.     

Developing a community-based approach to urban redevelopment

The purpose of this paper is twofold: first, to analyze the Joint Redevelopment Project (JRP), a housing renewal program in low-income residential communities, and second, to develop a community-based approach to urban redevelopment in Korea. In urban areas of Korea, particularly in Seoul, housing renewal has systematically reduced the supply of substandard housing in the areas where low-income families have concentrated, thereby isolating and marginalizing the displaced tenants. Housing renewal or urban redevelopment projects are basically profit-oriented rather than upgrading-oriented for a community by means of community dynamics and residents' participation. Although many renewal projects have contributed to the increase of homeowners among middle-income families who had enough financial resources for the purchase of a house, there have been no programs giving sufficient consideration to tenants. In fact, most renewal projects displaced low-income residents affected by housing speculation and attracted more middle-income families into the projects.For local governments, a community-based approach to urban policy means encouraging comprehensive planning and cooperation between governments and communities. It is a holistic approach built around families and communities. We need to use a learning and enabling process in order to develop a community-based approach to redevelopment in urban areas of Korea.

4D-Var data assimilation system for a coupled physical-biological model

A 3-compartment model of phytoplankton growth dynamics has been coupled with a primitive-equation circulation model to better understand and quantify physical and biological processes in the Adriatic Sea. This paper presents the development and application of a data assimilation procedure based on optimal control theory. The aim of the procedure is to identify a set of model coefficient values that ensures the best fit between data and model results by minimizing a function that measures model and data discrepancies. In this sense, twin experiments have been successfully implemented in order to have a better estimation of biological model parameters and biological initial conditions.

Local, global and virtual buzz: The importance of face-to-face contact in economic interaction and possibilities to go beyond

Novel information and communication technologies have created new possibilities for transferring information and knowledge over distance. Although this might open up broad options for economic interaction, knowledge regarding the effects of these changes on the geographies of production and innovation is still incomplete. Under these circumstances, permanent co-location and face-to-face (F2F) interaction may be efficient in some contexts but not in others. Support by computer-mediated communication (CMC), temporary, and virtual interaction is increasingly becoming the basis for establishing trans-local production networks. By combining results from social psychology with economic geography, it is argued that there is no generally superior spatial fix for economic interaction. Different spatial configurations can be advantageous in different production and innovation contexts, even over large distances without permanent or even regular F2F contact. This paper systematically investigates the effects of new communication technologies and different organisational forms for economic interaction by emphasizing the potential of combining CMC with forms of temporary and permanent F2F interaction.

台湾金瓜石地质公园概念性规划之研究

1999年，联合国教科文组织推出“世界地质公园”(UNECO-Geopark)构想，与“世界遗产”同为国际上保护地球资产的重要概念。地质公园不仅保护特殊地质地形景点且鼓励科学研究，亦可作为推动地质旅游的基地，为地方创造经济发展的可能性。目前联合国教科文组织于2004年2月通过28个世界级的地质公园。地质公园逐渐成为世界各国推动地质地形保育的重要形式，其中以中国及欧盟国家发展最快。金瓜石地区是台湾31个优先推动设置地质公园的景点之一(王鑫、李光中，2003)。基隆山、本山及无耳茶壶山均是金瓜石地区重要的特殊地质地形景点，其成因与当地区域地质环境密切相关。金瓜石地区位于台湾基隆火山群分布区，以侵入式岩浆活动为主，是台湾金铜矿物高度聚集的地方(谭立平、魏稽生，1997；余炳盛、方建能，1995)。地下多样且高品位的经济矿物成为金瓜石地区的重要资产。1894年正式开采以来，开创了金瓜石九份地区繁华的年代。虽然今日矿业已停歇，但遗留下来的矿业遗迹及历史文化形塑了独特的地方特质，符合划设地质公园(以地质地形为主，以人文历史为辅)的条件。因此选择金瓜石地区作为研究区，进行地质公园概念性规划。本研究从“地球遗产保育”角度出发，就“分区管理”及“特殊地质地形景点保护”2个面向进行分析。首先透过“地势分析”将金瓜石地区分为4类10个景观同质单元，并进行地景特质描述。其次，以“叠慧法”对特殊地质地形景点进行“重要景点评选”、“景点评估”拟定“景点管理措施”，并取得专家群的共识及建议。最后提出3个管理分区，并将特殊景观区分为5个景区。
