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
Anywhere on Earth Anywhere on Earth Anywhere on Earth (AoE) is a calendar designation which indicates that a period expires when the date passes everywhere on Earth. The last place on Earth where any date exists is on Howland and Baker islands, in the time zone (the West side of the International Date Line), and so is the last spot on the globe for any day to exist. Therefore, the day ends AoE when it ends on Howland Island. The convention originated in IEEE 802.16 balloting procedures. At this point, many IEEE 802 ballot deadlines are established as the end of day using
