Impacts into marine and icy environments - A short review

In this review we discuss the current knowledge of impact events into marine and icy targets. This includes the major consequences of impact in marine depositional basins and on icy targets. We also discuss some of the future fields of research that could be of interest, in particular questions regarding triggering of volcanic activity, tsunami generation, and impact-associated petroleum reservoirs. In the discussion of the icy impact craters a summary of the exploration history is presented, both discussing comets and icy targets. An updated schedule for related missions is given, expressing the importance of knowing these processes also for understanding the development of the solar system.
