Researcher Marine GeosciencesJoin our Research department as a geologist or geophysicist for the EU project “BASTA”, which aims to address challenges concerning the efficient identification of buried and exposed munition in the sea, within an ever-growing set of available data. You will perform research on detailed 3D sub-bottom imaging for munition detection, using a novel approach for cost-effective data acquisition.
Researcher marine geosciences: sub-bottom imaging for munition detectionOffshore dumped munitions constitute a serious safety risk for users of our coasts and seas. In the past decade, various European research projects have put the topic on the political agenda, but many challenges remain. One of the major challenges concerns the efficient identification of buried and exposed munition within an ever-growing set of available data. Several good sensing technologies exist, but the different data are seldom fully integrated into a consistent framework. Moreover, for subsurface investigation (i.e. buried objects) the available technologies are not sufficient with regard to spatial (x,y,z) resolution. The EU project ‘BASTA ‘ (2020-2022) aims to address these issues and is aimed at cost-efficient detection and recognition of sea-dumped munition, both for regional scale reconnaissance and for local scale surveys of known sites. Major objectives include development of cost-efficient data acquisition combing ship-based and Autonomous Underwater Vehicle (AUV)-based surveys, joint analysis of data using Artificial Intelligence (AI) methodologies and multi-sensor databases, and on-route AI algorithm learning. The final goal is to develop a model that (1) predicts buried munition and (2) predicts the type of munition for surficial munition. The project combines research institutes and industrial partners from Germany and Belgium for maximum valorization of the developed techniques. The main task of VLIZ in the BASTA project concerns detailed 3D sub-bottom imaging for munition detection. Systems using a narrow acoustic beam (such as the parametric echosounder) provide the (sub-decimeter) resolution needed for object detection, but any objects that lie outside the survey path remain undetected. Recently, a novel 3D approach was developed using a multitransducer parametric echosounder system (SES-2000 Quattro). The system consists of four individual transducers in a line array, which allows 3D imaging with very high data density. This 3D approach will be compared with a smart 2D (or pseudo-3D) approach for deeper water, where possible involving an autonomous vehicle or platform. Both approaches will be tested in different test sites in the North Sea and Baltic Sea where ample ground-truth data/information is available. Finally, the approach will be verified at a test site where no/little information is available. Our offer
