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
Mid-Atlantic Regional Council on the Ocean (MARCO) for which we share responsibility remain healthy, resilient and productive for our children and theirs." Sarah Chasis, Senior Attorney and Director, Ocean Initiative, New York of the Natural Resources Defense Council noted in a blog posting that with the initiative "the Mid-Atlantic jumps to being a regional player on the ocean protection scene, on par with ecosystem-wide efforts by bodies like the West Coast Governors' Agreement." Mid-Atlantic Regional Council on the Ocean (MARCO) Mid-Atlantic Regional Council on the Ocean is a regional initiative by states in the Mid-Atlantic States region "to maintain and improve the health of our ocean and
