...-time information in the deep sea environment. Raman spectroscopy, which is a powerful tool to obtain in-situ "fingerprint" spectra from substances, is established as an attractive analytical method for deep ocean investigations due to the fact that water is a weak Raman scatterer. Furthermore, Raman...

... that a peak in low frequency shows swell component, and a peak in high frequency shows wind-wave component. Therefore, measured power spectrum can be expressed by the combination of swell and wind-wave spectra as shown in Fig. 7. [rad/s] Fig.6 Example of measured power spectrum of wave [rad/s] Swell...
