This is a collection of photographs from a research expedition to the eastern Antarctic Peninsula in 2018. A group of international oceanographers and atmospheric scientists embarked on this journey in Lyttelton, New Zealand, where the researchers and crew boarded the South Korean icebreaking research vessel, ARAON. The vessel sailed across the Antarctic Circle and eventually arrived at its destination in the Weddell Sea region of the Antarctic Peninsula. During this expedition, research activities were carried out which included helicopter operations, anchoring near the King Sejong Station, and sea ice and water column sampling. Finally, the vessel crossed the Drake Passage and docked in Punta Arenas Chile where the expedition concluded.
