Cultural content on the Web is available in various domains (cultural objects, datasets, geospatial data, moving images, scholarly texts and visual resources), concerns various topics, is written in different languages, targeted to both laymen and experts, and provided by different communities (libraries, archives museums and information industry) and individuals (Figure 1). The integration of information technologies and cultural heritage content on the Web is expected to have an impact on everyday life from the point of view of institutions, communities and individuals. In particular, collaborative environment scan recreate 3D navigable worlds that can offer new insights into our cultural heritage (Chan 2007). However, the main barrier is to find and relate cultural heritage information by end-users of cultural contents, as well as by organisations and communities managing and producing them. In this paper, we explore several visualisation techniques for supporting cultural interfaces, where the role of metadata is essential for supporting the search and communication among end-users (Figure 2). A conceptual framework was developed to integrate the data, purpose, technology, impact, and form components of a collaborative environment, Our preliminary results show that collaborative environments can help with cultural heritage information sharing and communication tasks because of the way in which they provide a visual context to end-users. They can be regarded as distributed virtual reality systems that offer graphically realised, potentially infinite, digital information landscapes. Moreover, collaborative environments also provide a new way of interaction between an end-user and a cultural heritage data set. Finally, the visualisation of metadata of a dataset plays an important role in helping end-users in their search for heritage contents on the Web.

Fundación Ciudad de la Energía (CIUDEN) is carrying out a project of geological storage of CO2, where CO2 injection tests are planned in saline aquifers at a depth of 1500 m for scientific objectives and project demonstration. Before any CO2 is stored, it is necessary to determine the baseline flux of CO2 in order to detect potential leakage during injection and post-injection monitoring. In November 2009 diffuse flux measurements of CO2 using an accumulationchamber were made in the area selected by CIUDEN for geological storage, located in Hontomin province of Burgos (Spain). This paper presents the tests carried out in order to establish the optimum sampling methodology and the geostatistical analyses performed to determine the range, with which future field campaigns will be planned.

La normalización de los métodos de análisis y de los principales aspectos relacionados con la conservación de los bienes culturales ha empezado en 2004 con la creación del comité europeo de normalización, CEN/TC 346 Conservation of Cultural Property, que tiene la responsabilidad no solamente de redactar protocolos de ensayos en laboratorio, sino también proponer las recomendaciones más adecuadas para designarlos de forma consensual y conservarlos de la forma más apropiada. Se comentan los aspectos relacionados con el origen de estas normas, el trabajo desarrollado y que muchas de ellas, aunque no estén dirigidas específicamente a la piedra, tienen en cuenta la presencia de este material en objetos arqueológicos, obras de arte, estructuras de fábricas y elementos ornamentales.

Los títulos de los proyectos de intervención en el patrimonio cultural tangible, como resultado del análisis de una muestra del inventario del fondo documental de la asociación española de empresas de restauración del patrimonio histórico (ARESPA), aporta la evolución de la terminología aplicada en los procesos de conservación. La restauración es una intervención frecuente, aunque en los títulos es común mencionar dos intervenciones. Sin embargo, para facilitar el inventario, catalogación y la consulta de la documentación, y teniendo en cuenta la complejidad del patrimonio construido, se propone especificar en los títulos los ámbitos físicos y los sistemas constructivos relacionados los estudios previos, las obras de emergencia, las intervenciones y el mantenimiento

The 15th International Geological Congress was held in South Africa in 1929. Many interesting issues were tackled, thanks to the development of geophysical techniques, ideas about magmatic differentiation, and the origin of the Karroo System, among others. The importance of the Congress from the point of view of the history of geology lies in the fact that an ‘inflection point’ occurred as regards thinking about the continental drift theory that had been proposed by Wegener a few years earlier. It can be said that the contributions of Du Toit allowed a deepening in the theoretical bases of this scientific hypothesis, which celebrated its first hundred years in 2012.

The “Innovatio Educativa Tertio Millennio” group has been 10 years developing educational innovation techniques, actually has reached the level of teaching on the technical teachers has developed, and share them with other groups, that can implement them in their teaching activities. UNESCO Chair of Mining and Industrial Heritage has been years working on heritage, and on the one hand teaching in conservation and maintenance of heritage, and on the other doing raise awareness of the meaning of heritage, the social value and as must be managed effectively. Recently these two groups work together, thus is spreading in a much more effective manner the concepts of heritage, its meaning, its value, and how to manage it and provide effective protection. On one hand being a work of dissemination based on internet and on radio broadcasting, and on the other one of teaching based on educational innovation, and courses, conferences, and face-to-face seminars or distance platforms.

Twelve years ago a group of teachers began to work in educational innovation. In 2002 we received an award for educational innovation, undergoing several stages. Recently, we have decided to focus on being teachers of educational innovation. We create a web scheduled in Joomla offering various services, among which we emphasize teaching courses of educational innovation. The “Instituto de Ciencias de la Educacion” in “Universidad Politécnica de Madrid” has recently incorporated two of these courses, which has been highly praised. These courses will be reissued in new calls, and we are going to offer them to more Universities. We are in contact with several institutions, radio programs, the UNESCO Chair of Mining and Industrial Heritage, and we are working with them in the creation of heritage courses using methods that we have developed.

Cultural heritage is a complex and diverse concept, which brings together a wide domain of information. Resources linked to a cultural heritage site may consist of physical artefacts, books, works of art, pictures, historical maps, aerial photographs, archaeological surveys and 3D models. Moreover, all these resources are listed and described by a set of a variety of metadata specifications that allow their online search and consultation on the most basic characteristics of them. Some examples include Norma ISO 19115, Dublin Core, AAT, CDWA, CCO, DACS, MARC, MoReq, MODS, MuseumDat, TGN, SPECTRUM, VRA Core and Z39.50. Gateways are in place to fit in these metadata standards into those used in a SDI (ISO 19115 or INSPIRE), but substantial work still remains to be done for the complete incorporation of cultural heritage information. Therefore, the aim of this paper is to demonstrate how the complexity of cultural heritage resources can be dealt with by a visual exploration of their metadata within a 3D collaborative environment. The 3D collaborative environments are promising tools that represent the new frontier of our capacity of learning, understanding, communicating and transmitting culture.

Geologic storage of carbon dioxide (CO2) has been proposed as a viable means for reducing anthropogenic CO2 emissions. Once injection begins, a program for measurement, monitoring, and verification (MMV) of CO2 distribution is required in order to: a) research key features, effects and processes needed for risk assessment; b) manage the injection process; c) delineate and identify leakage risk and surface escape; d) provide early warnings of failure near the reservoir; and f) verify storage for accounting and crediting. The selection of the methodology of monitoring (characterization of site and control and verification in the post-injection phase) is influenced by economic and technological variables. Multiple Criteria Decision Making (MCDM) refers to a methodology developed for making decisions in the presence of multiple criteria. MCDM as a discipline has only a relatively short history of 40 years, and it has been closely related to advancements on computer technology. Evaluation methods and multicriteria decisions include the selection of a set of feasible alternatives, the simultaneous optimization of several objective functions, and a decision-making process and evaluation procedures that must be rational and consistent. The application of a mathematical model of decision-making will help to find the best solution, establishing the mechanisms to facilitate the management of information generated by number of disciplines of knowledge. Those problems in which decision alternatives are finite are called Discrete Multicriteria Decision problems. Such problems are most common in reality and this case scenario will be applied in solving the problem of site selection for storing CO2. Discrete MCDM is used to assess and decide on issues that by nature or design support a finite number of alternative solutions. Recently, Multicriteria Decision Analysis has been applied to hierarchy policy incentives for CCS, to assess the role of CCS, and to select potential areas which could be suitable to store. For those reasons, MCDM have been considered in the monitoring phase of CO2 storage, in order to select suitable technologies which could be techno-economical viable. In this paper, we identify techniques of gas measurements in subsurface which are currently applying in the phase of characterization (pre-injection); MCDM will help decision-makers to hierarchy the most suitable technique which fit the purpose to monitor the specific physic-chemical parameter.

El concepto de custodia del territorio sigue siendo desconocido para los defensores del patrimonio minero de nuestro país. La custodia del territorio es una estrategia más para conservar los valores naturales, culturales y paisajísticos de una zona determinada. Para conseguir la implicación de los propietarios, las entidades de custodia emplean distintas estrategias e instrumentos con el objetivo de pactar, de forma voluntaria, un acuerdo entre las dos partes. Cuando se habla de la custodia como estrategia, hay que pensar en herramientas y métodos para acceder a la propiedad del patrimonio o para que los propietarios, sin dejar de serlo, se involucren en la conservación. Los encargados de las acciones requeridas, los agentes que protagonizan las acciones de conservación son las denominadas entidades de custodia. Actualmente hay innumerables entidades de custodia en todo el Mundo, que se dedican al patrimonio natural o cultural, pero que se dediquen específicamente a la protección del patrimonio minero son más escasas. Sin embargo la Sociedad Española para la Defensa del Patrimonio Geológico y Minero es, de hecho, una entidad de custodia, en muchos casos sin que sus socios seamos conscientes de ello. En el presente trabajo se intenta definir el concepto de custodia del patrimonio, aplicándolo al caso concreto del patrimonio minero, y se estudian distintos ejemplos de iniciativas para adquirir bienes inmuebles con el fin de preservar un patrimonio minero que estaba en peligro de desaparición. ABSTRACT The concept of land stewardship remains unknown to the defenders of our country’s mining heritage. Land stewardship is a strategy to conserve the natural, cultural and landscape values of a particular area. To encourage the involvement of the owners, the custodians employ different strategies and tools with the aim of reaching, on a voluntary basis, an agreement between the two parties. When it comes to custody as a strategy, you have to come up with tools and methods to achieve the ownership of the property or to encourage the owners to be involved in its conservation. Those responsible for the actions required, the agents who lead conservation actions are known as Custody institutions. Currently there are innumerable custodians around the world, dedicated to natural or cultural heritage, but those specifically engaged in the protection of mining heritage are scarce. However, the Spanish Society for the Defence of the Geological and Mining Heritage is actually an entity of Custody, in many cases without its partners being aware of this fact. This paper attempts to define the concept of guardianship of a property, applied to the case of mining heritage, and explores different examples of Spanish entities that employ initiatives to acquire property for the purpose of preserving mining heritage in danger disappearing

Until recently, cinematographic film was largely cellulose-triacetate-based. However, this material is highly susceptible to biodeterioration, thus placing historic film collections, an important part of the cultural heritage of many countries, at risk. In the present study, samples taken from several biodeteriorated color cinematographic films belonging to the collection of the Cuban Institute for Cinematographic Industry and Arts (ICAIC) were investigated. Infrared spectroscopy showed that all films were of the same composition, i.e., a gelatin emulsion coating one side of a cellulose-triacetate-based film support. The films were analyzed by environmental scanning electron microscopy and scanning electron microscopy to determine the degree of biodeterioration and the type of colonizing microorganisms. Significant fungal colonization was found on both sides of the films in all samples, with a higher concentration of fungi on the gelatin emulsion side. Epifluorescence microscopy of fluorochrome-dyed films demonstrated that some of the fungi were still active, indicating that the films under study, and probably others at the ICAIC, are at risk of further deterioration. Fungi were identified by molecular biology techniques. The fungi mainly responsible for the observed biodeterioration were those belonging to the genera Aspergillus and Cladosporium, although other genera, such as Microascus and Penicillium, were identified as well. In accordance with the findings described herein, the existing guidelines for the prevention and control of film biodeterioration are discussed.

La habitación rupestre en la Península Ibérica conforma un amplio conjunto de manifestaciones cuyos orígenes son difíciles de dilucidar. Existen conjuntos primitivos, posiblemente horadados durante la Antigüedad Clásica y Tardía, y otros que probablemente se originaron y excavaron en la Alta Edad Media, en los que se mezclan grupos de origen religioso y otros de probable uso defensivo. El conjunto peninsular es sin duda el más variado de Europa Occidental, pues recibió influencias árabes y usos de la cristiandad antigua, importados de Oriente Próximo, que por tanto relacionan estas manifestaciones con otras del arco mediterráneo. La supervivencia del uso de las cuevas a lo largo de la Baja Edad Media -una vez afianzada la Reconquista- es una incógnita, pero los usos rupestres volvieron a generalizarse en ciertos sectores de la Península durante la Edad Moderna, toda vez que el hábitat cuevero manifestó una eclosión relacionada con la peripecia de los moriscos, primero desterrados de sus habitaciones en el Sur y Este peninsular y luego expulsados en los albores del siglo XVII. Los que quedaron, nominalmente conversos, debieron habitar de nuevo cuevas en sus lugares de origen. Esos núcleos son los más abundantes, particularmente en la provincia de Granada y aledañas. Este substrato fue seguramente el punto de apoyo para la proliferación de las cuevas de habitación a partir del siglo XIX, en el cual un creciente proletariado agrícola y urbano necesitó de alojamientos baratos y no hizo sino imitar usos preexistentes, que se pueden rastrear en muchos de los núcleos rupestres que sobrevivieron mayoritariamente hasta bien entrado el siglo XX, y que se abandonaron gradualmente a partir de los años 60 de esa centuria. Para entonces, existían barrios de cuevas extensos en muchas provincias, destacando, aparte de las andaluzas, ciertas zonas de la Cuenca del Ebro (aragonesa, navarra y riojana), del arco periurbano de Valencia, del Sur de Madrid, de la Mancha toledana, o de las provincias de Albacete, Guadalajara, Murcia e incluso de Palencia. Los núcleos antiguos se excavaron -en razón de su origen dedicado a defensa y refugio- en lugares poco accesibles, que mayoritariamente se dan en relieves anfractuosos, en las orlas marginales detríticas y carbonatadas de las cuencas terciarias y en terrenos más antiguos de la geológicamente denominada Cuenca Vasco Cantábrica, en las cuales florecieron centros de eremitismo del primitivo condado de Castilla. También son lugares inaccesibles los riscos asomados a cantiles fluviales, cuya regularización morfológica natural ha sido causa de la ruina de múltiples hipogeos que se labraron con las mismas intenciones de refugio, defensa o retiro espiritual. Los núcleos modernos se han excavado ya en terrenos más propicios (los que componen las cuencas terciarias o "España arcillosa", mayoritariamente), y por ello observamos cómo abundan las litologías sedimentarias, que son aquellas en las que se horadaron casi todas las "colmenas" de habitación moderna en la Península. En unos casos y otros, existen rasgos comunes en lo relativo a la litología y comportamiento de los materiales excavados, y también en lo relativo a su evolución, meteorización y conservación. Se han estudiado por ello estas pautas comunes -como un posible avance para el establecimiento futuro de estudios de geoconservación del patrimonio rupestre habitado-, que se traducen en la determinación de los procesos de meteorización más característicos en los antros de la Península Ibérica -sean modernos o antiguos- y en la determinación de las relaciones más habituales entre geomorfología y tipología de las cuevas de habitación. También se exponen algunas conclusiones relativas a la resistencia de los tipos pétreos en relación a la antigüedad de los emplazamientos. Esta relación se explica bien si tenemos en cuenta que las cuevas antiguas trataban de ser lugares apartados en los que dominan rocas más resistentes -como se ha explicado- y que en las modernas se ha buscado la habitación permanente, en los materiales más blandos ocupan las depresiones terciarias del Centro, Este y Sur de la Península, colonizados no ya como refugios sino de modo seguro, y ya en arrabales "extramuros" de las ciudades. Geomorfológicamente, esta razón histórica tiene consecuencias sobre la posición de las cuevas, sobre su organización, y sobre su conservación. La extensión del dominio estudiado obliga prácticamente a bosquejar algunas de estas conclusiones geológicas, pero permite a su vez proporcionar una visión global acerca del patrimonio troglodítico desde una perspectiva geológica, y en ello radica la principal novedad de la investigación. Cave dwelling in the Iberian Peninsula comprises a great deal of examples whose origins are sometimes difficult to elucidate. There are primitive groups of caves, probably belonging to Classical and Late Antiquity, and other settlements that appear to have been created and excavated in the Early Middle Ages. Some of them are due to religious reasons and some others may probably have served for defensive uses. The Peninsular group is very likely the most diverse in Western Europe, for it was not only influenced by Arabs, but it also assimilated uses from the Antique Christendom, imported from the Middle East. In this sense, Iberian cave dwellings connect with those of the Mediterranean area. There is not total certainty about the survival of caves serving for dwelling throughout the Late Middle Ages, once the Reconquista was a fact. However, underground excavations for human habitation were once again dispread in certain zones of the Peninsula during the Early Modern period. This growth of underground habitats appears in connexion with Morisco’s vicissitudes; first of all, their removal from their settlements in South and Eastern Peninsula, and finally their expulsion from Spanish territory at the very beginning of XVII th century. Those of them who rested in Spain –and that were nominally “converts”- seem to have returned to cave dwelling in their places of origin, particularly in the province of Granada and its neighbouring zones. This substrate may have been the toehold for a new spreading of cave dwellings since XIX th century, when the increasing rural and urban proletariat returned to the pre-existent uses of caves in order to solve the necessity of affordable housing. This fact can still be detected in many of the rock settlements that have survived during a great part of the XX th century and which were gradually abandoned from the 60´s onwards. There were important cave dwelling districts in many Spanish territories by that time, and not only in Andalusia. We also find them in certain areas of the Ebro basin (those of Aragon, Navarra and La Rioja), in the peri-urban arc of Valencia, in the South of Madrid province and also in the provinces of Toledo (the so called “Mancha toledana”), Albacete, Guadalajara, Murcia or even Palencia as well. Due to their defensive and refuge uses, primitive underground habitats were dug in hardly accessible places. The majority of them are located in mountainous and rough areas, when not in the marginal borders of Tertiary basins, where coarse detritic and carbonate formations outcrop. Cave dwellings can also be found in more ancient rock masses, such as those of the Basque Cantabrian Mesozoic Basin, which is the area where hermit centres of the primitive County of Castile first flourished. Cliffs surrounding fluvial valleys are as well inaccessible places, but here we find that geological evolution has caused the destruction of many rock sanctuaries and cliff dwellings that were originally dug with the same purposes of defence, refuge and spiritual retreat. Later modern cave settlements were dug in quite more favourable terrains, mainly in the soils that compose the Tertiary basins, generally known as “España arcillosa” or “Clayey Spain”. Therefore, we find abundant sedimentary fine and medium grained lithologies, which are the ones that have hosted the majority of Modern Era warren cave dwellings in the Iberian Peninsula. Actually, both types of cave dwelling share some standards regarding the lithology of the excavated materials, and they share as well certain patterns that affect to their evolution, weathering and preservation. These common patterns have been studied here in order to determine the most characteristic weathering processes that affect the majority of the Iberian caves, both Antique and Modern. And also with a view to establish the most habitual relationships between geomorphology and typology of cave dwellings. The study may as well provide a first basis for future studies on geo-preservation of cave dwellings heritage. We also reach some conclusions about the strength of different rocks concerning the antiquity of the sites. As we have already pointed out, this relation comes from the fact that ancient caves were placed in remote or isolated locations, where harder rocks outcrop, while more modern ones result from people´s search of permanent dwelling. In this sense, the softer rocks of the Tertiary Basins of Middle, East and South Peninsula provided a secure colonization to this second and modern group. And moreover, considering geomorphological features, this historical reason has had an effect not only on the position and location of the caves, but also on their organisation/structure/distribution and preservation. The huge extension of our domain of interest almost forces to sketch out some of these geological conclusions. But at the same time it gives a global panorama of Spanish troglodyte heritage, seen from a geological perspective. And here is the main novelty of this research.

The Cultural Heritage constitutes a way to generate social identities and play an important role in the development of the Spanish Mediterranean cities that opt to sustainable quality tourism. The reflection on the necessity of intervention on this heritage, in addition to establishing what should be done, brings up the need to define the reasons for taking action, why and what-for. These decisions are essential to establish if its maintenance and recovery are economically sustainable. The Project "Cartagena Port of Cultures", with support from the European Union, is an example of effective instrument for ensuring the sustainability of our built heritage conservation. Its main objective was to enable sustainable development of tourism in Cartagena based on sustainability and seasonality. This was achieved through a process of recovery of heritage resources and their optimum promotion and marketing.

The aim of this work is an approach using multisensor remote sensing techniques to recognize the potential remains and recreate the original landscape of three archaeological sites. We investigate the spectral characteristics of the reflectance parameter and emissivity in the pattern recognition of archaeological materials in several hyperspectral scenes of the prehispanic site in Palmar Sur (Costa Rica), the Jarama Valley site and the celtiberian city of Segeda in Spain. Spectral ranges of the visible-near infrared (VNIR), shortwave infrared (SWIR) and thermal infrared (TIR) from hyperspectral data cubes of HyMAP, AHS, MASTER and ATM have been used. Several experiments on natural scenarios of Costa Rica and Spain of different complexity, have been designed. Spectral patterns and thermal anomalies have been calculated as evidences of buried remains and change detection. First results, land cover change analyses and their consequences in the digital heritage registration are discussed.
