PhD Thesis title: Seaweed as food, fodder, and fertiliser: Methods of identification, impacts, and implications of past seaweed use in archaeology

Supervisors: Dr Ingrid Mainland (UHI Archaeology Institute), Dr Mark Taggart (UHI ERI), Dr Philippa Ascough (SUERC) and Prof Jörg Feldmann (TESLA, University of Aberdeen).

Magdalena undertook her PhD studies at Orkney Archaeology Institute from 2016-2020, researching past seaweed consumption, and the implications that seaweed consumption by sheep holds for our understanding of the past. As part of this, she researched how the chemical and isotopic composition of skeletal material changes with the consumption of seaweed in modern material, and analysed archaeological material, including sheep from the Ness of Brodgar, to identify past seaweed consumption. Magdalena also studied the effects of fertilising barley with seaweed in a field trial (pictured) in partnership with our Agronomy Institute and the James Hutton Institute in Dundee.

At UHI research conferences, Magdalena received prizes for the best poster by a postgraduate student (2016), and best student presentation (2017) for her work on identifying seaweed-consumption from skeletal remains. At the UK Archaeological Science Conference 2017, her poster on the identification of seaweed-eating by analysis of sheep’s teeth was awarded the first prize for a student poster, and her presentation on the effects of seaweed fertilisation on grain crops at the AEA 2018 conference in Denmark was awarded the best student presentation prize. Since finishing her PhD, Magdalena has started a Postdoc position at the University of Vienna.
