Ледяные поля, вносят дополнительные отражения в сейсмограммы, которые трудно отличить от отражений, поступающих от месторождений углеводородов, имеющих большое значение для геологов. Для уменьшения влияния отражений от ледяного поля сейсмический источник импульса часто устанавливается глубоко в ледяном покрове, приближаясь к границе контакта льда и слоя воды. В данной работе представлены результаты математического моделирования распространения сейсмических волн в геологических слоях Арктики с помощью сеточно-характеристического метода. Проведен анализ влияния установления источника импульса на границе между льдом и водой на снижение скоростей сейсмических волн, на волновые поля. Модель с источником сейсмического импульса, расположенным на границе контакта между льдом и водой, дает худший конечный результат, в то время как модель с источником импульса на поверхности льда демонстрирует уменьшение скоростей сейсмических волн.</p></abstract><trans-abstract xml:lang="en"><p>Different ice constructions, such as ice fields, ice ridges, icebergs, are of great interest for the research, for example, in the seismic prospecting works. Ice constructions, especially ice fields, bring in lots of extra reflections into the seismograms, which are very difficult to differ from the reflections, coming from the hydrocarbon deposits, which are of great importance for the geologists. For the decrease of the influence of the reflections from the ice field, the seismic source of impulse is often established deep into the ice cover, approaching the contact border between the ice and the water layer. In this work, the results of mathematical modelling of the seismic waves spread through the geological layers of the Arctic region with the help of the grid-characteristic method are presented. The analysis of influence of establishing the source of impulse on the border between ice and water on the decrease of the seismic wave velocities, on the wave fields is carried out. The model with the seismic source of impulse, located on the contact border between ice and water, makes worse the final result, while the model with the source of impulse on the surface of ice demonstrates a decrease of the seismic wave velocities.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ледяные поля</kwd><kwd>ледяные гряды</kwd><kwd>айсберги</kwd><kwd>арктический регион</kwd><kwd>сейсмический источник импульса</kwd><kwd>сеточно-характеристический метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ice fields</kwd><kwd>ice ridges</kwd><kwd>icebergs</kwd><kwd>Arctic region</kwd><kwd>seismic source of impulse</kwd><kwd>grid-characteristic method</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">Petrov, Igor.
