ESSIC Research Associate Alek Petty participated in the Beaufort Gyre Exploration Project research cruise in the Beaufort Sea on-board the CCGS Louis S. St Laurent, Sept. 21st – Oct. 17th, 2014. Dr. Petty collected ship-based observations of the concentration, thickness and age of the sea ice pack. Petty authored an ongoing blog post during the cruise, which was published on the ESSIC Website. The blog provided a firsthand account of the trials and triumphs of the nearly month-long research adventure in the Beaufort Sea.
