During times when we are moving through sea ice, we frequently feel “bumps” (and are many times compelled to go outside or at least look out the window). It is amazing to think that these bumps are not due to rough seas. It is the ship running through sea ice. Then from inside the lower decks you can hear deafening scraping and knocking as the ice moves along the sides of the ship. It’s an unreal thing to hear and feel, when you think about what is really happening.
