(a) Time series variations of temperature, salinity, CTD-sensor depth, and Chl a concentration at stations K1 (CTD sensors were deployed at 160 m) and (b) K2 (CTD sensors were deployed at 180 m). Light blue dash lines in Fig. 2a show the temperature range of water which is not influenced by internal waves10. Note: Chl a sensor was not deployed at station K2.
