With the advancing applications of deep-water echosounders involving moored, towed, profiling and autonomous instruments, calibration of echosounders at the operating depth is needed to ensure unbiased estimates of biomass and species identification. In this context, the deepwater calibration acoustic facility (DeCAF) was used to examine the depth-dependent variations in on-axis gain (<span class=\"inline-formula\">⁠<span class=\"mathFormula\"></span><span class=\"MathJax_Preview\" style=\"color: inherit; display: none;\"></span><span class=\"MathJax\" id=\"MathJax-Element-1-Frame\" tabindex=\"0\" style=\"position: relative;\" data-mathml=\"<math xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot;><msub xmlns=&quot;&quot;><mrow><mi>G</mi></mrow><mrow><mn>0</mn></mrow></msub></math>\" role=\"presentation\"><nobr aria-hidden=\"true\"><span class=\"math\" id=\"MathJax-Span-1\" style=\"width: 1.565em; display: inline-block;\"><span style=\"display: inline-block; position: relative; width: 1.228em; height: 0px; font-size: 128%;\"><span style=\"position: absolute; clip: rect(1.416em, 1001.23em, 2.621em, -1000em); top: -2.288em; left: 0em;\"><span class=\"mrow\" id=\"MathJax-Span-2\"><span class=\"msub\" id=\"MathJax-Span-3\"><span style=\"display: inline-block; position: relative; width: 1.215em; height: 0px;\"><span style=\"position: absolute; clip: rect(3.145em, 1000.76em, 4.207em, -1000em); top: -4.018em; left: 0em;\"><span class=\"mrow\" id=\"MathJax-Span-4\"><span class=\"mi\" id=\"MathJax-Span-5\" style=\"font-family: MathJax_Math; font-style: italic;\">G</span></span><span style=\"display: inline-block; width: 0px; height: 4.018em;\"></span></span><span style=\"position: absolute; top: -3.868em; left: 0.786em;\"><span class=\"mrow\" id=\"MathJax-Span-6\"><span class=\"mn\" id=\"MathJax-Span-7\" style=\"font-size: 70.7%; font-family: MathJax_Main;\">0</span></span><span style=\"display: inline-block; width: 0px; height: 4.018em;\"></span></span></span></span></span><span style=\"display: inline-block; width: 0px; height: 2.288em;\"></span></span></span><span style=\"display: inline-block; overflow: hidden; vertical-align: -0.283em; border-left: 0px solid; width: 0px; height: 1.257em;\"></span></span></nobr>","AbstractOtherLang":"acoustics, deep-water, echosounder, split-beam","BibLvlCode":"AS","StandardTitle":"Deep-water calibration of echosounders used for biomass surveys and species identification","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:41.804898","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"acoustics, deep-water, echosounder, split-beam","OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2022-05-17","DateCreate":"2022-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000434070900021","VABBcode":null,"OpenAcc":1,"DOI":"10.1093/icesjms/fsx206"},"refs":null,"anarec":{"AnaID":352032,"PubliDate":2017,"Pagination":"1117-1130","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44710,"SerRR":"ICES Journal of Marine Science.
