QUESTION: Has the Polar Duke ever been surround by ice and had to wait a certain period of time to get free? Jeffery C., Mrs. Garvin's Science Class, Mauldin Elementary, Mauldin, SC ANSWER from Janet Barnes, Aboard the RV Polar Duke Sat, 5 Apr 1997 17:30:34 +0000 (GMT) Dear Jeffery, The Polar Duke has been surrounded by ice many times but can usually break free with no problem. However, one time the Duke was stuck for a week and had to wait until the wind and currents broke up the ice enough for the ship to push her way out! Thanks for your question! Janet
