The signature of these sources differs significantly from each other and depends on the parameters of their operation in each case. In addition, the streamer towing depth affects the resulting waveform. Typically, such a signature includes a primary source pulse, ghost waves reflected from the water-air surface from the source and from the receiver, secondary bubble pulsations, and possibly other oscillations associated with the characteristics of the source. The resulting complex signature, if it cannot be suppressed by processing, significantly reduces the resolution of the seismic images. Even now, during g high-resolution seismic data processing, it is usually not possible to completely effectively suppress the signature, which leads to the loss of the potential advantages of high-resolution seismic surveys and a decrease the quality of the resulting images. In this article we will go through some examples of data acquired with different types of sources and discuss approaches to suppressing noise waves contained in the resulting signature.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Near-surface section (NSS) geological features were studied based on acquired data analysis on the example of three separated regions of Vostochno-Prinovozemelsky area. The main goal was clarification of NSS and geological hazards identification inside studied area. Gas-saturated sediments, paleovalleys and faults were distinguished in each region. Faults genesis and morphological traits issues, definition of deformation nature of NSS and geological hazards identification at the bottom and in near-bottom sediments were studied. Similarities and differences in studied section structure were found. In the first two regions Touronian-Santonian seismic sequence complicated by series of faults formed due to clay dehydration was defined. In the second region deformations inside Oligocene-Miocene seismic sequence were found. They were likely formed by glacial activity. Moreover, there were paleovalleys that had different nature compared to the one that depressions in the third region had. In general, glacial sediments wide spread was defined in the first two regions, which was unnatural for the third region. That means that Barentsevo-Kara glacial boundary, reviewed in the work ( Svendsen et al., 2004 ), is located between the second and the third regions.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124271997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The placement of any structure within the landslide leads to its activation. To design an engineering structures on the landslide slopes, the project’s designers are using the results of a complex engineering surveys, which are necessary for calculating the stability of soil masses, as well as assessing the risks of the development of landslide processes during the construction and operation of the engineering structures. Correct calculation of the landslide slopes stability requires a detailed study of structural features, as well as the research of soil properties within the landslide massif. Although the traditional methods used in engineering and geological surveys are accurate and constantly are being improved, they have one significant drawback - these methods are based on one-dimensional interpretation of drilling data and field methods for studying soils, which does not allow engineering and geological researches of heterogeneous landslide structures with the required detail. Moreover, steep landslide slopes make it difficult to conduct drilling operations, this creates additional difficulties in studying the structural features and identifying weakened zones in the landslide massif. In contrast to 1D methods of researching the slope by drilling wells and field methods of studying the strength properties of soils, modern 2D geophysical technologies allow getting a continuous section of a landslide slope showing the main structural elements of the landslide massif and localising zones of weakened rocks. In order to assess the significance of additional information about the structure of landslides, extracted using geophysical methods, for the value of slope stability, we performed calculations of the stability of the studied landslide slope both on the basis of engineering and geological survey data and taking into account additional geophysical information.","PeriodicalId":383927,"journal":{"name":"Engineering and Mining Geophysics 2021","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132112028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
