Characterization of threats arising from climate change and identification of impacts on archaeological sites

Elena García Martinez, Marta Plaza Beltrán — Tue, 18 Feb 2025 00:00:00 +0000

In initial stages, the conservation of archaeological sites had a reactive nature, in which interventions were aimed at alleviating damage caused by different causes and returning them to their state closest to the original. Later, thanks to the incorporation of the discipline in preventive conservation, the interventions are preceded by an identification of the impacts produced and consist of measures that, proactively, aim to alleviate future deterioration. The threats derived from climate change represent a challenge in which, first of all, we have to anticipate the identification of the impacts with the help of projections; Secondly, it is necessary to study unknown vulnerabilities and finally, implement adaptive measures to face this new situation.

This article contemplates the first phase, with a review of the studies carried out that relate to the threats derived from climate change and the impacts identified on archaeological sites.

Protecting instrumental scientific heritage: the functionality and use versus conservation debate. Tools for preservation, recovery and dissemination

Laura Díaz Moreno — Tue, 18 Feb 2025 00:00:00 +0000

Lack of knowledge, lack of resources or the emergence of new technologies are just some of the factors that keep scientific and technical heritage in the shadows of other types of heritage. Functionality is presented as a new indispensable concept when studying both science-related objects and the most appropriate conservation and restoration processes in these collections. The aim of this article is, therefore, to highlight the value of scientific heritage, specifically the instruments, and to reflect the challenges faced by those responsible for this heritage with two examples: the CSIC instruments and the scientific university collections. Moreover, the creation of reproductions or replicas is a very useful tool for preserving and disseminating the scientific instrumental heritage.

Towards a better understanding of foxing in paper: precursors, sources and characteristics

Daniela Silvana Nitiu, Andrea Cecilia Mallo, Mario Carlos Nazareno Saparrat — Fri, 28 Feb 2025 00:00:00 +0000

Paper is the most commonly used medium for historical records, yet it is susceptible to aesthetic and mechanical transformations caused by biological, chemical, or physical factors. The effects of deterioration are often visible through foxing stains. The aim of this review is to provide an up-to-date overview of the various hypotheses regarding the origins of foxing on paper, given its complexity, destructive potential, and the mechanisms that remain unclear. This review proposes a multifactorial explanation for foxing, applying the concept of the “disease triangle” and attributing the phenomenon to the action of microorganisms, the conductive environment and interactions with the susceptible substrate. Understanding the nature of foxing is a key issue in paper preservation and should be considered a priority in conservation strategies for archives and museums. Multifactorial experimental studies are necessary to try to facilitate the precise identification of the genesis of this process.

Finding (Recognizing) immovable Modern Heritage. Comparative analysis of the accessibility and visibility in Immovable Cultural Heritage Information Systems in Spain

Mon, 07 Apr 2025 16:11:18 +0000

This article presents a comparative analysis of the Information Systems for Cultural Heritage (ISCH) designed and developed in Spain by the autonomous administrative regions. Specifically, the study focuses on the accessibility and visibility of modern immovable heritage within these systems. To this end, the research is developed in three phases: definition of the criteria and functions to be analysed; comparative analysis of immovable heritage in general within the ISCHs; diagnosis focused on the modern heritage of a series of selected cases.
The research concludes that there are significant gaps and deficiencies that hinder the use, accessibility, visibility and knowledge of modern heritage in the country as a whole. It also highlights the unevenness and lack of standardisation of criteria, terms, functions and resources among the various ISCHs. Finally, the study proposes strategies for improving the accessibility and functionality of the ISCHs, making a scientific and transfer-oriented contribution to the different regional institutions.

Management, evaluation of the conservation needs and hierarchization of a collection through its inventory

Tue, 06 May 2025 18:26:28 +0000

For the conservation of paleontological materials, it is essential to have all the information that affects each specimen in an orderly manner and based on the experience acquired in the conservation of the vertebrate collection from the Upper Cretaceous site of Lo Hueco (Fuentes, Cuenca), it has been designed a management-oriented database.

For data collection, information on the morphology and composition of the specimens and the state of conservation has been considered. All these data have been evaluated and calculated by combining in the same tool the valued information on the state of conservation, vulnerability to deterioration agents and the scientific, educational and historical value of the specimens, which facilitates the management of the collections. This information also allows to establish priorities in the strategies of conservation of the collection directed to the hierarchization of its needs.

Documentation of the current state of the temple of Our Lady of Candelaria: implementation of photogrammetry as an auxiliary technique.

Tue, 06 May 2025 19:00:09 +0000

A survey of the Temple of Our Lady of Candelaria in Villa Purificación, Jalisco, Mexico, was conducted with the objective of creating a detailed architectural representation that includes the identification of materials and pathologies. Digital photogrammetry was used to take organized photographs using a handheld camera and a drone. The result was a point cloud that was used to develop architectural drawings in CAD software, obtaining relevant information on dimensions and materials. Based on this, color mapping was performed on the south facade of the temple to identify different materials and pathologies. It is considered that the implementation of photogrammetry resulted in a reliable and useful technique, although it has some drawbacks that can be detailed later with the same photographic collection. The contextualization of the environment revealed possible causes of pathologies related to humidity in a semi-humid tropical environment, for example: bulky elements such as buttresses generate periods of sun and shade, reducing the evaporation of humidity necessary for the proliferation of organisms.
