Meteorological and sea surface water measurement data from Icebreaker Research Vessel ARAON for 2010-2019 Arctic research expeditions

Abstract

Despite of its economic and scientific significances with mineral resources, the Northern Sea Routes, and climate change, the Arctic Ocean has been a challenge for long-term continuous environmental observations. Since its inception in 2009, the ice-breaker research vessel ARAON has been conducting an annual expedition in the Arctic Ocean for the last 10 years from 2010. All the Arctic expeditions have been carried out mainly in August-September when the sea ice extent shrinks and the thickness becomes relatively thin around the Bering Sea, Chukchi Sea, Beaufort Sea, and high latitudes over the Russia, the US, and Canada. IBRV ARAON can conduct research activities through a variety of research equipment such as on-board meteorological data and surface temperature & salinity monitoring data of seawater. In this study, meteorological observation elements including solar radiation, air temperature, relative humidity, wind speed, and wind direction are presented. In addition, sea surface water temperature and salinity monitoring elements including water temperature, salinity, conductivity, and sound speed are presented.
