Troll with the subsurface current, in this case coming into the inside turn or coming into or along the tip of the point.
But both pockets can be moved by surface or subsurface current.
Conventional ROVs are therefore seen as being a key operating limitation in the design (and cost) of the marine operations for tidal energy installations, where subsurface current speeds of 5.
Beneath these legal protections are subsurface currents which relegate immigrants and foreigners, especially non-whites to marginal vocations and jobs.
Lagrangian-style surface and subsurface currents are addressed through drifter tracking; use of HF Doppler radar is for surface current characterization and remote sensing for imaging of seawater motion signatures are also discussed.
Faults are electromagnetic hot zones where electrical currents from the atmosphere are interacting with the subsurface currents called telluric or Earth currents.
Yin decided to figure out how much those subsurface currents would warm during this century and the next.
From the speed and direction of subsurface currents, Teague and his colleagues estimated the hurricane's wind speed and a parameter called the coefficient of drag, which describes how efficiently the wind's momentum transfers to surface waters.
Changes in subsurface currents, temperature, and salinity eventually change conditions at the surface, where the ocean interfaces with the atmosphere.
Our knowledge about many subsurface currents is even more rudimentary, which suggests that we will find many more surprises in our ocean-circulation studies.
