In the STFC funded Epistemic Insight Initiativeproject, The Power of Light, a series of resources have been designed informed by co-creation activities,pilot lessons, and workshops that involved children in schools and with their families in community spaces.Through this project with Diamond, we brought into classrooms and community spaces how light can be used to help investigate the world around us, address real-world problems and inform our thinking about Big Questions. The resources we develop support teachers' and their students' sense of agency when exploring 'how knowledge works' and how knowledge is built through different disciplines (includingthe natural sciences, the arts, and the humanities). This 'zine', with its focus on how scientists have been working with historians and archaeologists to preserve the Mary Rose (Henry the Eighth's favourite ship that was sunk in the Solent in England's southern coast),has been developed through co-creative activities involving research scientists at Diamond Light Source (UK), academics, primary school teachers, STEM ambassadors, and Diamond's public engagement team. Zines use an appealing combination of text and images to create a concise comic-like narrative formatto generate enthusiasm about a particular area of interest - the series of zines designed for this project focuses onresearchtaking place at the Diamond facility.The Diamond Light Source facilityhouses a synchrotron which is used to conduct research in a variety of applied fields of science and technology. This zine is designed to be accessible to ages 8+, and works well with a short animation (available in both Zenodo and on the Epistemic Insight You Tube channel)that has been created with additional funding from STFC. Teaching notes are available for this zine, with guidance and activity sheets to support working with the Power of Light resources. This zine explores these discussion questions: 1) What are examples of changes we can observe? 2) What helps us to know more about the things around us? 3) What might we use to help us observe changes?

If left to dry uncontrollably following excavation, marine archaeological wood suffers significant and irreparable damage. Conservation treatments are required to consolidate degraded wood and to remove residual water. Drying must be controlled to eliminate erratic and heterogeneous water removal. Monitoring and understanding the drying process progression is invaluable information to garner real-time knowledge to correlate with chemical and physical material properties, and to develop future conservation strategies. Here, polyethylene glycol (PEG) consolidated marine archaeological wood was periodically sampled during drying to determine the moisture content as a function of location, time, and sample depth. The heterogeneous nature of the material leads to significant noise across spatial and temporal measurements, making it challenging to elucidate meaningful conclusions from visual observation of the raw data. Therefore, the spatiotemporal data was computationally analysed to produce a representative model of the ship’s drying, illustrated by a dynamic simulation. From this we can quantitatively predict the drying rate, determine the depth-dependence of drying, and estimate the resulting equilibrium moisture content. This is the first time such simulations have been carried out on this material and conservation process, demonstrating the power of applying numerical modelling to further our understanding of complex heritage data.

We report a microfocus X-ray absorption (XAS) investigation of a thin film sample from an iron contaminated wooden arrow tip raised from the seabed with the Mary Rose. The XAS studies were combined with optical and scanning electron microscopy measurements. The arrow tip had been treated with polyethylene glycol (PEG) soon after it had been raised and stored in a controlled environment. The measurements revealed a significant concentration of iron sulfide nanoparticles. This indicates that in this sample there was a reduction of the oxidative effects of the normal ambient atmosphere that is usually seen in untreated timbers. The film was treated overnight with an aqueous solution of diethylenetriaminepentaacetic acid (DTPA), which is normally very effective in sequestering iron. This had little effect in terms of removing iron from the film and possible explanations are discussed.

This master's thesis is intended as a foundation for further development of methods for digital marine osteoarchaeology. The main purpose of this thesis was to examine and problematise the process of locating, documenting, and analyzing skeletal remains in marine archaeological, and other hard to reach sites. Three forms of osteological analysis' was performed and assessed: one based on analysis of physical skeletal remains, another based on 2D documented skeletal remains, and a third on analysis on 3D reconstructed skeletal remains. The secondary purpose of this thesis was to problematise the taphonomic effects on bodies, body parts, and bones in marine environments, necessary for the evaluation of the different methods. The analysis' has been conducted on source material provided by the research projects for the naval ships Mars and Gribshunden, the National Maritime Museum of Sweden, the Sandby Borg project, and the Çatalhöyük project. In addition, a test was carried out, with eight volunteer osteology students at Campus Gotland, Uppsala University, during a seminar exercise. The results collected through the osteological analysis' performed on the three different formats and the students osteology exercise could be used in order to highlight a variation of data available in the different formats. The results was then used in order to create a basis for future digital documentation methods that may be applied in the field. The secondary aim of this thesis was addressed through the use of the naval ships Mars and Gribshunden as case examples in order to address the limited amount of skeletal remains located so far at the marine archaeological sites. Denna master uppsats är ämnad som grund för vidare utveckling av metoder för digital marinosteoarkeologi. Det huvudsakliga syftet med uppsatsen är att undersöka och problematisera problemen kring at lokalisera, dokumentera, och analysera skeletala kvarlevor vid marinarkeologiska, och andra svåråtkomliga lokaler. Tre olika slags osteologiska analyser utfördes: en baserad på analyser av skeletala kvarlevor, en annan baserad analyser av 2D dokumenterade skeletala kvarlevor, och en tredje baserat på analyser av 3D rekonstruerade skeletala kvarlevor. Det sekundära syftet uppsatsen var att problematisera den tafonomiska påverkan på kroppar, kroppsdelar, och ben i marina miljöer, nödvändiga för utvärderingen för de olika metoderna. Analyserna har utförts på källmaterial som tillgängliggjorts genom forskningsprojekten för skeppen Mars och Gribshunden, Statens Maritima Museer i Sverige, Sandby borg projektet, och Catalhöyük projektet. Utöver detta har även en studie utförts tillsammans med åtta frivilliga osteologistudenter vid Campus Gotland, Uppsala Universitet, under en seminarieövning. Resultaten som samlades in genom de osteologiska analyserna av de tre olika källmaterialen och student studien användes för att kunna understryka den datavariation som fanns tillgänglig för de olika källmaterialen. Resultaten användes för att skapa en grund för framtida digitala dokumentationsmetoder som kan appliceras i fält. Det sekundära syftet med studien besvarades genom att använda skeppen Mars och Gribshunden som exempel för att kunna diskutera den begränsade mängden skeletala kvarlevor som hittills hittats vid de marinarkeologiska lokalerna.

In recent years, there has been increased interest in examining alternative polymers for the conservation of archaeological artefacts, particularly waterlogged timbers, providing better, renewable, greener alternatives to poly(ethylene glycol) (PEG). The degradation of PEG consolidants in the timbers of the sixteenth century warship Mary Rose has been examined and the rheological and thermal properties of PEG have been compared with its monomethyl and dimethyl ethers and several polysaccharide consolidants (chitosan, guar, and 2-hydroxyethyl cellulose) in order to evaluate their potential as alternative consolidants for the conservation of waterlogged wooden artefacts. Additionally, the effect of the polymers on the archaeological wood was characterised by thermogravimetric analysis and solid-state nuclear magnetic resonance spectroscopy. The results suggest that the future of conservation technologies lies with polysaccharide consolidant materials, which show enhanced compatibility with wooden artefacts with no detectable side effects while also being cheap, with extremely low toxicity, renewable, and sustainably resourced.

The preservation of our cultural heritage is of great importance to future generations. Despite this, significant problems have arisen with the conservation of waterlogged wooden artifacts. Three major issues facing conservators are structural instability on drying, biological degradation, and chemical degradation on account of Fe 3+ -catalyzed production of sulfuric and oxalic acid in the waterlogged timbers. Currently, no conservation treatment exists that effectively addresses all three issues simultaneously. A new conservation treatment is reported here based on a supramolecular polymer network constructed from natural polymers with dynamic cross-linking formed by a combination of both host-guest complexation and a strong siderophore pendant from a polymer backbone. Consequently, the proposed consolidant has the ability to chelate and trap iron while enhancing structural stability. The incorporation of antibacterial moieties through a dynamic covalent linkage into the network provides the material with improved biological resistance. Exploiting an environmentally compatible natural material with completely reversible chemistries is a safer, greener alternative to current strategies and may extend the lifetime of many culturally relevant waterlogged artifacts around the world.

The Tudor warship the Mary Rose sank in the Solent waters between Portsmouth and the Isle of Wight on the 19th of July 1545, whilst engaging a French invasion fleet. The ship was rediscovered in 1971 and between 1979 and 1982 the entire contents of the ship were excavated resulting in the recovery of over 25,000 objects, including the skeleton of a small to medium sized dog referred to as the Mary Rose Dog (MRD). Here we report the extraction and analysis of both mitochondrial and genomic DNA from a tooth of this animal. Our results show that the MRD was a young male of a terrier type most closely related to modern Jack Russell Terriers with a light to dark brown coat colour. Interestingly, given the antiquity of the sample, the dog was heterozygotic for the SLC2A9 gene variant that leads to hyperuricosuria when found in modern homozygotic animals. These findings help shed light on a notable historical artefact from an important period in the development of modern dog breeds.

A comparison of ancient DNA (single-nucleotide polymorphisms) and carbon and nitrogen stable isotope evidence suggests that stored cod provisions recovered from the wreck of the Tudor warship Mary Rose, which sank in the Solent, southern England, in 1545, had been caught in northern and transatlantic waters such as the northern North Sea and the fishing grounds of Iceland and Newfoundland. This discovery, underpinned by control data from archaeological samples of cod bones from potential source regions, illuminates the role of naval provisioning in the early development of extensive sea fisheries, with their long-term economic and ecological impacts.

The Mary Rose was King Henry VIII's flagship before it sank in battle on the 19th July 1545. Over four hundred men went down with the ship and the environment of the Solent meant their remains were quickly covered in silt. Between 1979 and 1982 the remains of 179 individuals were recovered and examined as part of the excavation of the Mary Rose. The anaerobic environment created by the silt preserved the sailors' bones in remarkable condition and to date much has been learnt about life on the ship. In this study we used Raman spectroscopy (a non-destructive technique), to investigate the chemistry of the human bones, specifically for the identification of disease in archaeological specimens, for the first time. Raman data were collected from five anatomically normal tibiae and five tibiae that were bowed (individuals suspected to have suffered from bone disease in childhood). The data were processed using multivariate analysis (principal component analysis) and results showed the presence of chemical abnormalities in the bowed bones which resulted in the separation of the bones into two clearly defined groups, normal and bowed.
