- Environmental archaeology is a complex mix of empirical analysis and qualitative interpretation.It is increasingly data science oriented, and databases and online resources are becoming increasinglyimportant in large scale synthesis research on changes in climate, environments and human activities.Research funders, journals and universities place much emphasis on the use of data repositories toensure transparency and reusability in the research process. Although these are important, researchersthemselves, however, may have more use for research databases which are oriented more towardsadvanced querying and exploratory data analysis than conforming to archiving standards. This paperexplores the pros and cons of these different approaches. It also discusses and problematizes somekey concepts in research data management, including the definitions of data and metadata, along withthe FAIR principles. Research examples are provided from a broad field of environmental archaeologyand palaeoecology. In contrast to most publications, the developer’s perspective is also included, anda worked example using the Strategic Environmental Archaeology Database (SEAD) to investigate fossilbeetle data demonstrates the implementation of some of this in the real world. This example may befollowed online using the SEAD browser, and all described data downloaded from there. After providingboth encouragement and warnings on the use of digital resources for synthesis research, some suggestionsare made for moving forward.

- A comprehensive study has been launched in the medieval fortress of Carcassonne involving a cooperation between the universities of Umeå and Rennes, and the research institute of IRSTEA of Montpellier. This study aims to combine several spectroscopic techniques in order to resolve archaeological problems related to which raw materials were used during the city wall construction, and also to improve our understanding of the different phases of construction and use of the city walls. This study was also used for elucidating the different qualities and weak points of the applied field methods.

- This article reports on a new project to investigate the activities of early Homo sapiens in the area of the Chotts ‘megalake’ in southernTunisia. Excavations in 2015 and 2019 at Oued el Akarit revealed one of a number of Middle Stone Age (MSA) horizons near the topof a long sequence of Upper Pleistocene deposits. The site identified as Oued el Akarit (Sondage 8) consists of lithic artefacts, bone fragmentsof large ungulates and pieces of ostrich eggshell. Many of the objects are burnt. Excavation of about nine square metres revealed thatthese were associated with a lightly trampled and combusted occupation surface. Amongst the identified artefacts were Levallois flakes someof which could be refitted, thereby indicating the generally undisturbed nature of the occupation. The lithic finds also included side scrapersand other tools diagnostic of the MSA but significantly no bifacial or tanged tools. OSL (Optically Stimulated Luminescence) dating of thesediments and AMS (Accelerator Mass Spectrometry) radiocarbon dating of ostrich eggshell have produced uncalibrated age determinationsin the range 37,000–40,000 years ago, one of the youngest ages for MSA sites in the region. This is the first example of a securely dated laterMSA occupation in a riparian environment in south-eastern Tunisia

Quantifying archaeo-organic degradation - A multiproxy approach to understand the accelerated deterioration of the ancient organic cultural heritage at the Swedish Mesolithic site Ageröd
- 2020

Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 15:9

Tidskriftsartikel (refereegranskat)abstract
- Despite a growing body of evidence concerning accelerated organic degradation at archaeological sites, there have been few follow-up investigations to examine the status of the remaining archaeological materials in the ground. To address the question of archaeo-organic preservation, we revisited the Swedish, Mesolithic key-site Ageröd and could show that the bone material had been subjected to an accelerated deterioration during the last 75 years, which had destroyed the bones in the areas where they had previously been best preserved. To understand why this has happened and to quantify and qualify the extent of the organic degradation, we here analyse the soil chemistry, bone histology, collagen preservation and palaeobotany at the site. Our results show that the soil at Ageröd is losing, or has already lost, its preservative and buffering qualities, and that pH-values in the still wet areas of the site have dropped to levels where no bone preservation is possible. Our results suggest that this acidification process is enhanced by the release of sulphuric acid as pyrite in the bones oxidizes. While we are still able to find well-preserved palaeobotanical remains, they are also starting to corrode through re-introduced oxygen into the archaeological layers. While some areas of the site have been more protected through redeposited soil on top of the archaeological layers, all areas of Ageröd are rapidly deteriorating. Lastly, while it is still possible to perform molecular analyses on the best-preserved bones from the most protected areas, this opportunity will likely be lost within a few decades. In conclusion, we find that if we, as a society, wish to keep this valuable climatic, environmental and cultural archive, both at Ageröd and elsewhere, the time to act is now and if we wait we will soon be in a situation where this record will be irretrievably lost forever.

Lago di Bargone, Liguria, N Italy : a reconstruction of Holocene environmental and land-use history

Tidskriftsartikel (refereegranskat)abstract
- Sediment micromorphology, chemistry and magnetic susceptibility of basin edge deposits at the small, mid-altitude peat site of Lago di Bargone, eastern Liguria, Italy, is compared with a full Holocene palynological sequence and radiocarbon dates from the central part of the peat bog. Micromorphology and MS550 results show that Neolithic to Copper Age forest disturbances and clearings as inferred from the pollen diagrams, occurred during a period of lower water-tables and intermittent drying out of the basin edge deposits. Extensive deforestation and expansion of heath and rassland during the Iron Age and Roman periods is associated with increases in soil erosion and in micromorphological indications of burning. It is argued that the very fine size range of the charred fragments seen in thin sections and the seeming absence of charcoal of coarser size range suggest a system of light, controlled burning, possibly akin to the local tradition of using fire to control weeds and to encourage new grass and herbaceous growth, and not local forest clearance by fire. Micromorphology of the late-Holocene peat contains herbivore dung possibly indicating the use of the site as a watering hole by domesticated stock. The overlying colluvium displays evidence of deep-seated erosion of the local soils and geology which is most likely to have been associated with local mining activities.
