North Atlantic Deep Water North Atlantic Deep Water formation has been dramatically reduced at times during the past (such as during the Younger Dryas or during Heinrich events), and that this might correlate with a decrease in the strength of the Gulf Stream and the North Atlantic drift, in turn cooling the climate of northwestern Europe. There is concern that global warming might cause this to happen again. It is also hypothesized that during the Last Glacial Maximum (LGM), NADW was replaced with an analogous watermass that occupied a shallower depth known as Glacial North Atlantic Intermediate Water (GNAIW).

Drift current through a square centimeter area perpendicular to the direction of flow. (i) Drift current density J, due to free electrons is given by: formula_1 (ii) Drift current density J, due to holes is given by: formula_2 Where: n - Number of free electrons per cubic centimeter. p - Number of holes per cubic centimeter formula_3 – Mobility of electrons in formula_4 formula_5 – Mobility of holes in formula_4 E – Applied Electric Field Intensity in V /cm q – Charge of an electron = 1.6 × 10 coulomb. Drift current In condensed matter physics and electrochemistry, drift current is the
