Gravity anomalies and crustal section across the Tonga Trench The seismic structure determined by Raitt, Fisher, and Mason [1955] for the Tonga trench was projected to one of the gravity profiles. The gravity anomaly profile computed on the basis of the seismic structure is in fair agreement ....
It can autonomously adjust according to the water depth, achieving a balance between buoyancy and gravity. Firstly, we define the depth error of the UUV: ⎧⎩⎨ 𝑧𝑒=𝑧−𝑧d𝑧˙𝑒=𝑧˙−𝑧˙d𝑧¨𝑒=𝑧¨−𝑧¨d (17) Similarly, since it is also a second...
