Одним из способов получения упругих свойств осадков являются ультразвуковые исследования. В июне 2024 г. в губе Ругозерской Кандалакшского залива Белого моря были проведены ультразвуковые исследования на образцах слабо консолидированных донных осадков, представленных илами и глинами различного минерального состава. Отбор проб был выполнен при помощи гравитационной трубы на 11 станциях, предварительно выбранных по результатам анализа сейсмоакустических профилей. Всего было отобрано 25 проб (трубок), глубина отбора составила от 0,2 до 2 м. На 88 образцах из отобранных трубок были выполнены измерения скоростей продольных и поперечных волн ультразвуковым методом. Определение скорости продольной волны проводилось по времени первых вступлений при фиксированной базе измерения (длине исследуемого образца), поперечной — по годографу прямой поперечной волны на сейсмограмме, получаемой за счет изменения базы измерений. Ультразвуковые исследования выполнялись с помощью пьезокерамических датчиков продольной и поперечной волн частотой 60 кГц и 100 кГц соответственно. Полученные в результате исследования скорости поперечных волн в осадках, представленных глинами и илами, составили от 10 до 40 м/с, продольных волн — от 1000 до 1800 м/с.</p></abstract><trans-abstract xml:lang="en"><p>Assessment of the elastic properties of bottom sediments is necessary for studying the engineering-geological conditions of the investigated water area. One of the methods for obtaining the elastic properties of sediments is ultrasonic research. In June 2024, ultrasonic studies were conducted on samples of poorly consolidated bottom sediments, represented by silts and clays of various mineral compositions, in Rugozerskaya Bay of the Kandalaksha Gulf in the White Sea. Sampling was carried out using a gravity corer at 11 stations, preliminarily selected based on the analysis of seismic-acoustic profiles. A total of 25 samples (cores) were collected, with sampling depths ranging from 0.2 to 2 meters. Ultrasonic measurements of compressional and shear wave velocities were performed on 88 samples from the collected cores. The compressional wave velocity was determined based on the first arrival times at a fixed measurement base (length of the sample), while the shear wave velocity was determined using the travel-time curve of the direct shear wave on the seismogram obtained by varying the measurement base. Ultrasonic studies were conducted using piezoelectric ceramic transducers for compressional and shear waves with frequencies of 60 kHz and 100 kHz, respectively. The resulting shear wave velocities in the sediments, represented by clays and silts, ranged from 10 to 40 m/s, while compressional wave velocities ranged from 1000 to 1800 m/s.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>слабо консолидированные осадки</kwd><kwd>скорости продольных волн</kwd><kwd>скорости поперечных волн</kwd><kwd>УЗИ</kwd><kwd>Кандалакшский залив</kwd><kwd>Белое море</kwd></kwd-group><kwd-group xml:lang="en"><kwd>poorly consolidated sediment</kwd><kwd>compressional wave velocity</kwd><kwd>shear wave velocity</kwd><kwd>ultrasound</kwd><kwd>the Kandalaksha Bay</kwd><kwd>the White Sea</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Horn I.W.
