We quantify the uncertainty on TSM concentration estimation from each scattering property. We further quantify the variability of the total (b<sub>p</sub>), side (b<sub>s</sub>) and back scattering (b<sub>bp</sub>) to mass concentration ratio and explain this variability in terms of the physical (size) and chemical (apparent density, refractive index) properties of the particles. We show that bbp, bp and bs correlate well with TSM (correlation coefficients higher than 0.92), though with considerable scatter along the regression line. We find that 75% of the predicted TSM concentrations from a model based on b<sub>s</sub> are within 29% of the measured TSM concentration and within 38% and 48% for b<sub>bp</sub> and b<sub>p</sub> based models, respectively. The variability of mass specific total scattering (b<sub>p</sub>*) is mainly explained by total geometric cross section (PSA) and backscattering ratio ( <i>b<sub>bp</sub></i> ~ ), with observations above (below) the regression line having significantly higher (lower) <i>b<sub>bp</sub></i> ~ and lower (higher) PSA. Variability of mass specific backscattering (b<sub>bp</sub>*) was smaller and could not be explained by a single parameter. We do find that points below the regression line have significantly lower densities (?a), PSA, refractive index (n), <i>b<sub>bp</sub></i> ~ and chlorophyll a:TSM ratio than points near or above the line. After classification of observations in Case 1 and 2 water types, we find that Case 2 waters (N=149) show significantly higher values of b<sub>bp</sub>*, ?a, n, <i>b<sub>bp</sub></i> ~ and PSA and significantly lower values for b<sub>p</sub>* and chla:TSM than for Case 1 waters (N=123).","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Variability of total, back and side scattering to mass concentration of marine particles","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2012-12-19","DateCreate":"2012-12-19","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":221453,"PubliDate":2010,"Pagination":"10","XtraPublOfAnaID":null,"ISBN":null,"Volume":null,"Issue":null,"BRefMon":221451,"BRefMonRR":"(2010).
