title: Changes in the ice situation on the Northern Sea Route depending on the movement of the Solar system planets
abstract: The paper considers the progress in the hydrographic support for navigation in various parts of the Northern Sea Route in terms of improving the methods for developing tentative forecasts of interannual changes of ice conditions. Among the approaches to solve the task the authors take into account factors that do not depend on the uncertainty of regional climate changes in the future. One of such factors is the main mechanical process in the Solar System — the orbital planetary motion. The paper
