Stories of subsistence People and Coast over the last 6000 years in the Limfjord, Denmark
The overarching aim of the project was to quantify environmental changes in the marine environment of the Limfjord and Kattegat from the Bronze Age (c. 4000 yBP) to the present day, and link these changes to cultural developments around the Limfjord. Diatom assemblages in the Limfjord and Kattegat were used as indicators of salinity changes and other previously published proxies such as pigments and mollusc assemblages from shell middens were also used to build a picture of the environmental changes. The cultural developments were especially evidenced in subsistence strategies as reflected in 15N and 13C dietary analyses of human bones from the area using 14C in a novel way in tooth increments to help to determine whether increased 15N was due to increased marine protein in the diet or breastfeeding. Hydrogen isotopes were used to distinguish whether high 15N in bone collagen was due to manuring practices or consumption of marine protein. Strontium isotopes were also used to show migration of some individuals into the region.

The project provided an understanding of coastal environmental change and established meaningful “baseline” conditions that have relevance to coastal populations and resources today. It also established changes to diet in Denmark from the Mesolithic to the Viking Age.
