An '''icebreaker''' is a special-purpose ship or boat designed to move and navigate through [[ice]]-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom.
'''[[Quin Blackburn]]''' was a geologist on the First and Second Byrd Expeditions and leader of the geologic party that explored the [[Transantarctic Mountains]]. Blackburn served as a geologist and seaman—before—the mast on the [[Richard E. Byrd|First Byrd Expedition]] (1928-1930). During this expedition, Blackburn and 41 other explorers were forced to winter over in the Little America base due to their ship being stuck in the pack ice.


For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through [[sea ice]]. Icebreakers clear paths by pushing straight into ice pockets. The bending strength of sea ice is so low that usually the ice breaks without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. Because a buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, icebreakers have a specially designed hull to direct the broken ice around or under the vessel.

During this expedition, he led a three-man team on a 1,500 mile trek across [[Marie Byrd Land]], investigating the geology of the [[Queen Maud Mountains]] while also sledging the length of the [[Scott Glacier]] onto the Polar Plateau. His prowess as an explorer was evident by the fact that his team returned from their long polar traverse having gained weight.
