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).

West Australian Current on the Western Australian Coast, the Leeuwin Current and Southern Australian Countercurrent, also flow along this coast, with the former flowing in the opposite direction. These 3 currents together contribute greatly to the rainfall and climate in the southwest region of Western Australia. West Australian Current The West Australian Current (or the Western Australian Current), is a cool surface current of the Southern Ocean and Southern Indian Ocean. It starts as the Southern Indian Ocean Current, a part of the larger Antarctic Circumpolar Current (also known as the West Wind Drift). As the current approaches Western Australia, it turns north,
