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
European Consortium for Ocean Research Drilling European Consortium for Ocean Research Drilling The European Consortium for Ocean Research Drilling (ECORD) is a consortium of 14 European countries and Canada that was formed in 2003 to join the Integrated Ocean Drilling Program (IODP) as a single member. ECORD is now part of the International Ocean Discovery Program, which addresses crucial questions in Earth, Ocean, Environmental and Life sciences based on drill cores, borehole imaging, observatory data, and related geophysical imaging obtained from beneath the ocean floor using specialized ocean-going drilling and research vessels and platforms. As a contributing member of IODP, ECORD is entitled to berths on
