A field trial in an ice-covered sea is one of the most important tasks in the design of icebreaking ships and offshore structures. To correctly estimate the ice load and ice resistance of a ship's hull, it is essential to understand the material properties of sea ice during ice field trials and to use the proper experimental procedure for gathering effective ice data. The first Korean-made icebreaking research vessel, "ARAON," had her second sea ice trial in the Arctic Ocean during the summer season of 2010. This paper describes the test procedures used to obtain proper sea ice data, which provides the basic information for the ship's performance in an ice-covered sea and is used to estimate the correct ice load and ice resistance of the IBRV ARAON. The data gathered from the sea ice in the Chukchi Sea and Beaufort Sea during the Arctic voyage of the ARAON includes the temperature, density, and salinity of the sea ice, which was believed to be from two-year old ice floes. This paper analyses the gathered sea ice data in comparison with data from the first voyage of the ARAON during her Antarctic Sea ice trial.

최근에는 대내외적 환경변화로 인하여 해양산업의 중요성은 높아지고 있다. 자원고갈, 기후변화, 북극해 개방 등으로 해양산업의 발전을 촉발하고 있다. IT와 융복합화가 요구되고 있는 신해양산업의 수요는 점차 높아지고 있다. 해양산업의 중요성에 대한 재인식이 필요한 시점이다. 따라서 국가차원의 해양산업 활동 수준을 평가하기 위해서는 해양산업에 대한 체계적인 분류체계가 구축되어야 한다.
