A restricted area has been proposed to become a Marine Protected Area and for the definition and follow-up of its ecological value, an intensive and integrated biology-geology project was set up (HABITAT Project, Degraer et al. 2002). On a biological level, three macrobenthic communities and one species association were defined and from a geological point of view most attention was paid to the optimal use of remote sensing techniques. From this, time- and cost-efficient monitoring tools were put forward and are being evaluated within the present study. The simultaneous application of side-scan sonar and very-high resolution multibeam is regarded an important tool. Although they are established imaging techniques, their capability towards seafloor classification and especially to detect macrobenthic communities needs further investigation; hence ground-truthing remains essential. Based on the already known links between the sedimentology and the macrobenthos on the one side and between the sedimentology and the side-scan sonar recordings on the other hand, a macrobenthic interpretation of side-scan sonar images could be worked out; from this a sonar classification table with a prediction towards a community preference was established. Still, this approach remains qualitative and experience is needed for its interpretation. The acoustic backscatter of very-high resolution multibeam images can also be studied and since it is expressed in numerical values (decibel), it can be statistically treated and further processed to develop a quantitative automated seafloor classification. One of the aims of the present study is to evaluate the side-scan sonar based classification table in a very restricted area (Trapegeer sandbank-Westdiep swale) in the western Coastal Banks. Moreover, very-high resolution multibeam data was also available and was processed and classified using an automated seafloor classification programma. The predictions towards the occurrence of macrobenthic communities were ground-thruthed using Van Veen grab samples that were analysed for their macrobenthic content and their sedimentology.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Evaluation of sonar techniques for the detection of macrobenthic communities","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2002,"DateUpdate":"2011-12-12","DateCreate":"2002-10-14","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":28349,"ISBN":null,"PubliDate":2002,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"29","Place":"Gent","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":28349,"InsID":2048,"Acronym":"MARELAC","FullStandardName":"Universiteit Gent; Faculteit Wetenschappen; Vakgroep Biologie; Msc.
