Notes

Schlindwein is packing up gear to bring back home. Seismometers usually record seismic waves generated by seafloor earthquakes or eruptions that travel through, and shake, the Earth. But in this case, Schlindwein's seismometers actually record seismic waves that travel up from the ocean bottom through the ocean and the ice floe. The seismometers were installed on foundations, then covered with a plastic bucket and buried in a mound of snow to reduce the amount of movement they would be exposed to. Over the course of this 40-day research cruise, Schlindwein has had to keep close track of the positions of the ice floes on which she has set up her temporary seismic stations. As the icebreaker Oden has moved and the ice pack has drifted, she has had to make sure that "her" floes do not drift more than 20 miles away from the ship. Again, the safety of helicopter pilots and passengers in case of emergency sets the limit. She had to take several helicopter trips to reposition her temporary seismic stations on suitable ice floes within range of the Oden.
