Concepts and instruments for sustainable management and presentation of a super archive for climate change, landscape formation and human habitation.
Don van den Biggelaar officially started as a PhD candidate on 1 January 2011 with the subproject The substratum of the New Land. Both the professional world (historians, geographers and archaeologists) and policy makers and administrators are not sufficiently aware that the substratum of Flevoland is a ‘super archive’ for climate change, landscape development and human habitation during the past 170,000 years.
Because Flevoland was covered by water for almost a millennium (until the reclamation in the 20th century), the information on landscape development and human habitation has been preserved exceptionally well. There is also, partly as a result of the New Monument Law, a growing number of archaeological and geological reports, which contain a wealth of data and offer good perspectives for synthesizing research on the substratum of the polders, but are all but inaccessible to the public.
Subproject 3 of Biography of the New Land has 4 objectives. It aims to demonstrate that:
- the substratum of Flevoland is a large archive of landscape development over a period of 170,000 years;
- a succession of well-preserved ‘relict landscapes’ can be found in this archive over large areas, containing valuable information about landscape development, hominin habitation and land use in the region;
- this archive is relatively very well preserved because of the sedimentary environment and the depth below ground level;
- insight into the geological composition of the subsurface is necessary to place known archaeological sites in the context of the landscape.
The objectives of this research are divided into two main themes:
- Landscape reconstructions of the past 170,000 years.
- The presence or absence of human habitation in a changing landscape. These traces could possibly be up to 220,000 years old.
From old to new, the four periods of investigation are as follows: Middle to Late Saalian; Younger Dryas; Mid-Holocene; Late Holocene.
Together, these periods cover the start of the biography of Flevoland (Middle to Late Saalian) up to AD 1942 (8 BP), the year that the reclamation of the first polder (Noordoostpolder, northern part of Flevoland) was completed.
Middle to Late Saalian (220 – 170 ka)
ka = thousands of years before AD 1950 (BP)
In the first period of investigation an overview is given of the landscape setting of the central Netherlands during the Middle to Late Saalian. Furthermore, an assessment is made of whether the gravel fraction of the Urk Formation along the line Rhenen – Almere (central Netherlands) is large enough for the production of artefacts (Van den Biggelaar et al., in review).
Younger Dryas (12.9 – 11.7 ka)
For the second period of investigation an inductive predictive modelling approach is used to select areas in southern Flevoland (central Netherlands) which are most likely to contain archaeological remains dating to the Younger Dryas (Van den Biggelaar et al., accepted).
Mid-Holocene (6000 – 5400 BP)
For the third period of investigation a geoarchaeological perspective on the adoption of crop cultivation in wetland areas is presented. To better understand the reason for this adoption in the Eem and IJssel/ Vecht valleys (Flevoland), the Mid-Holocene inundation history and soil condition of these valleys were investigated (Van den Biggelaar et al., 2015).
Late Holocene (1200 – 8 BP)
In the fourth period of investigation the clay sequence of Schokland was studied to reconstruct the island’s flooding history during the last 1200 years (Van den Biggelaar et al., 2014). In addition, OSL dates are provided for the sandy laminae of late Holocene storm surges in the clay deposit on the former island Schokland. These dates improve the age model of the island’s flooding history during the last 1200 years (Van den Biggelaar et al., in prep.).
