Acoustic Mapping of Submerged Stone Age Sites—A HALD Approach

Rostand Tayong Boumda

+13

Acoustic response from lithics knapped by humans has been demonstrated to facilitate effective detection of submerged Stone Age sites exposed on the seafloor or embedded within its sediments. This phenomenon has recently enabled the non-invasive detection of several hitherto unknown submerged Stone Age sites, as well as the registration of acoustic responses from already known localities. Investigation of the acoustic-response characteristics of knapped lithics, which appear not to be replicated in naturally cracked lithic pieces (geofacts), is presently on-going through laboratory experiments and finite element (FE) modelling of high-resolution 3D-scanned pieces. Experimental work is also being undertaken, employing chirp sub-bottom systems (reflection seismic) on known sites in marine areas and inland water bodies. Fieldwork has already yielded positive results in this initial stage of development of an optimised Human-Altered Lithic Detection (HALD) method for mapping submerged Stone Age sites. This paper reviews the maritime archaeological perspectives of this promising approach, which potentially facilitates new and improved practice, summarizes existing data, and reports on the present state of development. Its focus is not reflection seismics as such, but a useful resonance phenomenon induced by the use of high-resolution reflection seismic systems.

Comprehensive Review on the Use of Machine Learning Techniques Applied to the Ultrasound Data for the Characterisation of Porosity across Carbon Fibre Reinforced Polymer Layers

Carbon fibre reinforced polymers (CFRP) are increasingly being used in different industries, including the automotive and aerospace sectors. One important reason for this is because they have interesting structural and mechanical properties compared to metallic materials. Their high strength-to-weight ratio makes them a preferred choice for high-stress applications. However, CFRPs are often subjected to various defects during their manufacturing that can significantly alter their structural integrity and durability. Amongst these defects, the occurrence of void formation (known as porosity) is the most common. Many methods have been developed for the characterisation of porosity including the ones based on the use of ultrasound data. The present work aims at providing a comprehensive review of the application of machine learning (ML) techniques to the mapping and characterisation of porosity across CFRP composites. The types of ML used, and their potentials for improving the accuracy of porosity detection are presented and discussed. It is particularly noted that ML techniques can extract unique features from CFRP complex ultrasound data with a relatively good level of accuracy. This result suggests that these techniques, particularly the convolutional neural network (CNN), would overcome the limitations of traditional signal processing techniques.

Teledyne Chirp III high-resolution seismic data were acquired over a three-year period at a water depth of 6.0–9.0 m, with a clear concentration of acoustic “haystack” features, in the dredged Svanemøllen Harbor, Copenhagen. The recordings show haystacks related to preserved shallow basins and rivers in the paleo-coastal setting. Eleven short vibrocores were retrieved below these pronounced haystacks and a sandy interval, underlain by clayey till and overlain by harbor mud, which represent the basin configuration. Two cores contained four pieces of knapped flint in the sandy interval (statistical density of around 230 pieces per square meter), while the remaining cores did not reach the desired depth. Finite Element (FE) modeling revealed that the small pieces of knapped flint were resonant and that the acoustic impedance of the flint was high. The Svanemøllen Harbor site is a hitherto unknown buried Stone Age site, and this is the first time ever that an unknown submerged, buried Stone Age site has been acoustically detected (using Teledyne Chirp III), verified by means of coring and modeled using FE modeling. The Innomar and Geopulse data acquired at the site did not register any haystacks. Due to the global sea level rise after the Last Glacial Maximum, a significant part of the world’s submerged Stone Age sites must be expected to be buried in seafloor sediments.

About Me

Dr Rostand Tayong Boumda is a Senior Lecturer at the University of Bedfordshire since 2019. He got his Master of Science by Research at the Ecole Centrale de Lyon in France in 2007. He then completed a PhD thesis in 2010 Acoustics of porous media at the University of Burgundy (France) with a thesis entitled “Acoustical properties of systems incorporating Micro-Perforated Panels (MPP) and absorbing materials under high sound pressure levels of excitation”. His research experience encompasses various disciplines with an emphasis on materials testing, their numerical and analytical characterisation and also Finite Element modelling. His PhD thesis and various post-doctoral positions afterward aimed at investigating inhomogeneous, perforated and complex media when subjected to various mechanical conditions and excitations including high sound pressure levels. Rostand has been the Principal Investigator (PI) for some Engineering and Physical Sciences Research Council (EPSRC) projects which aimed at characterising 3D Woven Composite materials using ultrasound methods. He is the member of the Institution of Engineer and Technology (IET) and was awarded many grants and prizes including the young scientist grant 2012 from the European Acoustics Association (EAA), the international young scientist grant 2012 from the International Noise Control Engineering (INCE, InterNoise) and the 2018 best presentation at the Early Career Researcher Event organized by the RCND (UK)
