Subsurface investigation in the Belgian intertidal zone is severely complicated due to high heterogeneity and tides. Near-surface geophysical techniques can offer assistance since they allow fast surveying and collection of high spatial density data and frequency domain electromagnetic induction (EMI) was chosen for archaeological prospection on the Belgian shore. However, in the intertidal zone the effects of extreme salinity compromise validity of low-induction-number (LIN) approximated EMI data. In this paper, the effects of incursion of seawater on multi-receiver EMI data are investigated by means of survey results, field observations, cone penetration tests and in-situ electrical conductivity measurements. The consequences of LIN approximation breakdown were researched. Reduced depth of investigation of the quadrature-phase (Qu) response and a complex interpretation of the in-phase response were confirmed. Nonetheless, a high signal-to-noise ratio of the Qu response and viable data with regard to shallow subsurface investigation were also evidenced, allowing subsurface investigation in the intertidal zone. © 2013 Elsevier B.V.

An overview will be presented of stable isotope data (δ13C and δ15N) available from animal and human bones from Roman to post-Medieval Belgian sites. The data will be used to assess trends in the human diet and evaluate the possible impact of reservoir effects originating from the consumption of fish derived from marine or freshwater environments. Historical and archaeozoological data demonstrate drastic changes in fish consumption throughout the last 2 millennia and thus suggest that fluctuations through time of the impact of the reservoir effects can be expected. However, the present stable isotope data set does not support this suggestion. © 2014 by the Arizona Board of Regents on behalf of the University of Arizona. Source

In 2000, the remains of a cog, Doel 1, were found in Doel, Belgium. Wood species identification of all ship timbers and smaller elements was performed. European oak was the dominant species, followed by alder that was used for the fairings. In total 150 ring-width series were recorded. The construction date was set at AD 1325/26 and the timbers proved to originate from forests along the rivers Elbe and Weser. For the bottom strakes a strict symmetrical layout was observed. The keel plank was hewn from a trunk with a slightly earlier felling date. Repairs were performed with high-quality boards, some with a southern Baltic provenance. © 2013 The Nautical Archaeology Society. Source

Ocean and Coastal Management

Maritime and coastal cultural landscape, encompassing land and sea, and underwater is an important part of our cultural resources in the coastal areas. Although, integrated coastal zone management (ICZM) has theoretically addressed the importance of cultural ecosystems, cultural resources have mostly been overlooked in holistic coastal management plans. Overlooking cultural resources results in loss of cultural identity associated with certain habitats; loss of tourism, recreational and educational opportunities; decline in local ecological knowledge, skills and technology pertaining to habitat management; and loss of opportunities for social and cultural capital. Literature and practice show that there is no proper definition and evaluation of coastal cultural heritage is available and coastal cultural heritage has not been considered as a resource with high level of benefit for development and people. Acknowledging the importance of coastal cultural heritage as a resource in ICZM, and the role that ICZM can play in linking land and sea management approaches highlights the necessity of new methods for defining and evaluation of coastal cultural heritage. This paper proposes models and guidelines for defining and evaluating coastal cultural heritage to be included in Marine Spatial Planning (MSP) and ICZM as a resource through application of the integrative complexity theory and learning from the experiences in management of other coastal resources. The results will be an integrative evaluation method and a guideline for delineating coastal cultural areas. The method and tool will be examined through the case of Ostend in Belgium. © 2015 Elsevier Ltd. Source

Environmental Archaeology

Inspired by archaeological finds from Kilise Tepe in southern Turkey, this paper explains how the internal structure of nacreous shell can indicate which type of shell was its source. Previous work in the biological sciences demonstrated that it is possible to distinguish between gastropods/cephalopods and bivalves by observing the arrangement of the aragonite tablets in the nacreous layer, and that the thickness of these tablets is fairly constant within taxa but can differ between them. This study verifies these properties by scanning electron microscopy on modern and ancient material, and discusses the benefit in the field of archaeology. The text is not the result of full-scale research but rather a proof of concept to explore the potential of the topic. It is shown that the difference between gastropods/cephalopods and bivalves can indeed be established by looking at the internal architecture of their mother-of-pearl, but that it is problematic to further discriminate between taxa. The thickness of the aragonite tablets is not a reliable distinctive feature. The microstructure of the overlying prismatic layer is a useful parameter when it is preserved. © 2014 Association for Environmental Archaeology. Source
