Finite vertical oscillation of fluid parcel in a heterogeneous,incompressible sea water—Part II

Observations of temperature fluctuations and simultaneous observations of temperature and salinity fluctuations conducted in the sea are carefully analyzed on the theoretical basis developed in Part I. Observed remarkable fluctuations of about 10 minutes period are considered to agree with the unstable oscillations obtained from the theory. Actual oscillations observed in the sea are regarded to have small wave length such that they satisfy the condition (F) described in the Section 1 of Part I.
