Ice with the smallest linear dimensions (less than 2 m) is called the brash ice. Such ice can be formed in natural conditions at water freezing and as a result of dynamic processes in ice cover, as well as due to human activities at sea. The latter type of ice is the one that has recently posed a serious problem to shipping in freezing sea areas. The paper describes the main properties of brash ice and considers the ways to meet the challenges of this phenomenon.</p></abstract><trans-abstract xml:lang="ru"><p>Ледяной покров на поверхности воды отличается большим разнообразием своего строения, включая линейные размеры ледяных образований. Лед с наименьшими линейными размерами (менее 2 м) называется тертым. Такой лед может образовываться как в естественных условиях при замерзании воды и при динамических процессах в ледяном покрове, так и из-за хозяйственной деятельности человека. Именно такой тертый лед в последнее время начинает создавать серьезные затруднения для породившего его судоходства в замерзающих акваториях. В статье описываются основные свойства тертого льда и рассматриваются способы борьбы с этим явлением.</p></trans-abstract><kwd-group xml:lang="en"><kwd>brash ice</kwd><kwd>porosity</kwd><kwd>cohesion</kwd><kwd>angle of internal friction</kwd><kwd>build-up</kwd><kwd>freeze-up</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тертый лед</kwd><kwd>пористость</kwd><kwd>сцепление</kwd><kwd>угол внутреннего трения</kwd><kwd>нарастание</kwd><kwd>смерзаемость</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Сазонов К.Е.
