Measuring and assessing the physical impact of beam trawling
Jochen Depestele,Ana Ivanovic,Koen Degrendele,Moosa Esmaeili,Hans Polet,Marc Roche,K. Summerbell,Lorna R. Teal,Bart Vanelslander,Finbarr G. O’Neill +9 more
TL;DR: In this paper, the authors measured the changes in seabed bathymetry following the passage of these gears using a Kongsberg EM2040 multi-beam echosounder and use a LISST 100X particle size analyser to measure the concentration and particle size distribution of the sediment mobilized into the water column.
Seafloor change detection using multibeam echosounder backscatter: case study on the Belgian part of the North Sea
Giacomo Montereale-Gavazzi,Giacomo Montereale-Gavazzi,Marc Roche,Xavier Lurton,Koen Degrendele,N. Terseleer,V. Van Lancker,V. Van Lancker +7 more
TL;DR: In this paper, pre-, ensemble and post-classification approaches were tested on an eight km2 study site within a Habitat Directive Area in the Belgian part of the North Sea.
Morphological evolution of the Kwinte Bank central depression before and after the cessation of aggregate extraction
TL;DR: In this paper, an analysis of the records of ships registers and Electronic Monitoring Systems of trailer suction hopper dredgers, operating on the Belgian Continental Shelf, reveal that 75% of the total extracted volume originates from only one sandbank, the Kwinte Bank.
Control of the repeatability of high frequency multibeam echosounder backscatter by using natural reference areas
Marc Roche,Koen Degrendele,Christophe Vrignaud,Sophie Loyer,Tim Le Bas,Jean-Marie Augustin,Xavier Lurton +6 more
TL;DR: In this article, the suitability of a natural area to provide a stable and uniform backscatter response must be carefully considered and demonstrated by a sufficiently long time-series of measurements.
Recommendations for the sustainable exploitation of tidal sandbanks
V. Van Lancker,Wendy Bonne,Erwan Garel,Koen Degrendele,Marc Roche,Dries Van den Eynde,Valérie K. Bellec,Christophe Briere,Michael Collins,Adonis F. Velegrakis +9 more
TL;DR: In this article, the authors synthesize the results of multidisciplinary research, which has taken place in the area and, on the basis of these findings, considers the need for an efficient management framework, in both the planning and monitoring stages of the extraction.
