Ocean acoustic tomography water formation and the gyre circulation. Other applications include the measurement of ocean tides, and the estimation of ocean mesoscale dynamics by combining tomography, satellite altimetry, and in situ data with ocean dynamical models. In addition to the decade-long measurements obtained in the North Pacific, acoustic thermometry has been employed to measure temperature changes of the upper layers of the Arctic Ocean basins, which continues to be an area of active interest. using data from acoustic pulses sent from one end of the earth to the other. Acoustic thermometry is an idea to observe the world's ocean basins, and the
Ocean Girl is reunited with Neri. But PRAXIS sees this pyramid as a danger to the Earth. Much of the final season is thus concerned with PRAXIS' attempt to attack the pyramid, as well as with a "Red Virus" which is spreading in the oceans of Neri's homeworld, the Ocean Planet. Eventually, in the series finale, Jason, Brett, and Neri are able to repulse PRAXIS' efforts and the rebellion, and Earth is saved. Neri remains on Earth as the ambassador of the Ocean Planet, and she and Jason finally become a couple. The Bates family, Winston, Neri, Charley, and the ORCA computer
