moreThis scientific report presents the results of the research project Skeletons in the Closet – Investigations of Climate Change and the Degradation of Archaeological Cultural Environments in Svalbard (CLIMARCH, Part 1B: Osteological Analysis – Jensenvatnet). The project received funding
from the Svalbard Environmental Protection Fund to carry out new osteological analyses of skeletal material dating to the whaling period (17th–18th centuries), excavated from the burial ground at Jensenvatnet (ID 93826) on Danskøya in Smeerenburgfjorden in 1984. The aims of the
project were 1) to investigate the preservation conditions of the skeletons and grave material at Jensenvatnet, and assess how climate- and
erosion-related processes affect the cultural environment, and 2) to collect osteological data that may provide new knowledge about health, living
conditions, and biological variation among whalers and seafarers in an early modern European context that is rarely preserved elsewhere.
1) The review of excavation data and more recent documentation shows that the burial ground at Jensenvatnet was already heavily affected by
erosion in 1984. All 19 graves investigated in Burial Ground 2 were to varying degrees exposed to soil creep, slumping, and cracking of the
ground surface, and several graves had already partially or completely collapsed into the erosion scarp. Stone grave markers were often deformed or entirely missing, and the coffins were generally collapsed, crushed, or deformed. As a result, skeletons, textiles, and other organic remains had in many cases been exposed to sediments, water, and oxygen. At the same time, the osteological analyses show that the skeletons
are generally well preserved compared to other European contexts, despite such damage. A clear relationship was observed between location
and preservation: individuals situated close to the erosion edge are far more fragmented and affected by post-mortem damage than individuals
located further inland within the cemetery. A comparison of measurement data and documentation from 1984, 1998–1999, 2014, 2018–2019,
and 2025 further demonstrates that erosion at Jensenvatnet has changed character in recent years. After a long period of relative stability, new
data from 2025 document a clear acceleration, with losses of up to two metres in the most exposed parts of the site since 2018. This development now threatens previously undisturbed graves. The results indicate that preservation conditions at Jensenvatnet are being affected by the same processes documented elsewhere in the Arctic, particularly increased wave activity, reduced duration of protective sea ice, and
permafrost degradation, all of which weaken sediment stability and increase vulnerability to coastal erosion. Compared to Likneset, the material from Jensenvatnet appears to be generally more poorly preserved, likely due to the extensive impact of erosion.
2) The osteological analysis includes 18 individuals from 16 grave contexts in Burial Ground 2 (ID 93826). The assemblage is dominated by young adults, with a predominance of males: 72% of the individuals were assessed as male or probably male, while the remaining 28% were assessed as possibly male or indeterminate. Several of the sex assessments are therefore uncertain, and biological sex can only be securely established through aDNA analyses. Furthermore, 61% belong to the Young Adult age category (20–34 years). Four individuals were assessed as Middle Adult (35–50 years), while two individuals represent late juvenile/young adult age (16–20 years). Stature could be estimated for 12 of
the 18 individuals, with an average height of 165.4 cm, which is lower than at Likneset. Dental analyses show a high prevalence of enamel hypoplasia (78.6%), caries (50%), dental calculus (64%), and clay pipe wear (79%), indicating childhood stress, disease, and habitual behaviour. Evidence of scurvy was recorded in 46% of the assessable individuals (6 of 13), showing that vitamin deficiency and nutritional stress formed part
of the disease profile, though to a lesser extent than at Likneset. The assemblage also shows a high frequency of degenerative and activityrelated skeletal changes, recorded in 75% of the individuals (12 of 16), particularly in the spine, shoulder girdle, hips, and lower limbs. At least six individuals (38%) display characteristic changes in the region of the costoclavicular complex, also observed at Likneset, which may be linked to intense and repetitive use of the upper body. More generally, several individuals show clear evidence of heavy physical labour, repetitive
movements, and long-term mechanical stress from an early age. Some individuals differ in that they exhibit distinct pathological features. One individual presents with blunt-force trauma to the frontal bone and bony changes in the ear canal consistent with prolonged exposure to cold wind and sea spray, while another young individual shows extensive pathological changes in the spine, pelvis, and lower limbs, in whom tuberculosis cannot be ruled out. Taken together, the analyses show that the whalers buried at Jensenvatnet lived under demanding conditions, marked by
hard physical labour, disease, nutritional stress, and social variation. Compared with Likneset, the material points to differences in stature, disease patterns, and preservation, which may suggest that the burial grounds in Smeerenburgfjorden represent different groups, phases of use, and historical contexts. The results also underline the considerable potential of the burial material and the need for further studies of preservation, dating, textiles, isotopes, and aDNA.
