The the concept is capable of carrying a certain amount of material as long as its velocity remains fairly constant; however, any obstruction, such as a submarine rock ridge or a land point cutting across the path of the current, will cause loss of velocity and consequent loss of carrying power.
C. The western part of the subpolar gyre in the deep (western) part of the Bering Sea.
D. A transform plate boundary is where two lithospheric plates slide past each other and where crust is neither produced or destroyed. [Wikipedia]
