Analysis of temperature measurements at a mooring in the Norwegian Sea was performed. The mooring operated for two years at 73°22′ N and 7°18′ E with the mooring replaced after a year of operation. The mooring was positioned south of the critical latitude (74°30′ N) for internal tides with a frequency of M2. Temperature variations which reflect fluctuations associated with internal waves varied depending on the vorticity at the measurement point. Cyclonic and anticyclonic eddies were alternately located in the study area. In the presence of anticyclonic eddies, peaks in the temperature spectra were noted caused by internal waves. When a cyclonic eddy approached, the peaks disappeared notwithstanding the fact that the buoy was positioned south of the critical latitude.
