AB: The depth integrated ocean flow directly impacts the magnetic and electric field generation associated with the sea water movement. The implications are that (1) the ocean flow generates non-trivial magnetic fields, and these need to be considered while processing geomagnetic data and (2) the measured geomagnetic data contain signatures of ocean flow and the magnetic data can possibly be used to infer the flow strength and variability. This paper describes an overview of the recent efforts to study the motional induction due to ocean circulation, tides and tsunami. In addition we will also discuss the attempts to recover/extract the ocean magnetic fields from satellite magnetic data.
