The optical modules are subject to motion in the presence of deep sea currents, and an acoustic triangulation system is needed to determine their positions to provide the required tracking precision and angular resolution for astronomical neutrino source searches.
Up until about 55 million years ago, carbon isotope ratios from samples taken from 14 sites around the globe show that deep sea currents had been generally forming in the Southern Ocean and South Atlantic Ocean and flowing northward to the Pacific Ocean.
It will set off on a mission to help map deep sea currents in Antarctica.
McCave, I. N., Thornalley, D. J. R. & Hall, I. R. Relation of sortable silt grain-size to deep-sea current speeds: calibration of the 'mud current meter'.
Essentially an extension of the Gulf Stream, that deep-sea current carries relatively warm salty water from the South Atlantic and the Caribbean to the northern reaches of the Atlantic.
This isolation may be the consequence of the formation of multiple transform faults ~1-2 Mya in the region reinforced by a strong transverse deep-sea current at the Equator [ 62].
Deep-sea currents are slower than surface currents, limiting the ability of the deeper plumes to spread extensively.
One possibility being investigated is that the species were able to travel between the poles along cold, deep-sea currents.
The idea that surface winds can influence deep-sea currents is surprising, and it suggests that the atmosphere's influence may extend far deeper into the oceans than previously thought.
Applied to deep-water underfilled basins, however, the sea-level assumption yields results that are unsatisfactory and in many cases misleading, reflecting the influence of additional controls, including tectonic movements, deep-sea currents and climate (e.g. glaciation) on stratal geometries and facies architecture.
The results could shed light on what might happen if deep-sea currents change because of global warming.
