Topographic Rossby waves (TRWs) were observed with a period of approximately 35 h using a mooring observation on the shelf break of the Chukchi Sea in the Arctic Ocean. One mooring (CP14) was deployed at 74.80°N and 167.89°W during the Araon Cruise (ARA05B) by Korea Polar Research Institute (KOPRI). The mooring was equipped with an upward looking acoustic Doppler current profiler (ADCP, Workhorse sentinel [WHS] 600 kHz) at approximately 58 m, a downward looking ADCP (WHS 300 kHz) at approximately 63 m, 29 temperature sensors (Sea Bird Electronics [SBE] 56 and SBE 37-SM), and four salinity sensors (SBE 37-SM). Data were collected for approximately one year from 21 August 2014 to 5 August 2015. Observed TRW events coincided with local sea ice concentration (MASAM2: Daily 4-km Arctic Sea Ice Concentration) and wind-stress (ERA-Interim daily reanalysis dataset) events.
