Abstract
Analysis of temperature measurements at a mooring in the Norwegian Sea was performed. The buoy station operated for two years at 73°22′ N, 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 the M2 frequency. 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 caused by internal waves were noted. When a cyclonic eddy approached, the peaks disappeared, despite the buoy positioned south of the critical latitude.
