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 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, parallel to the western coast of Australia, and becomes the West Australian Current. The current is mainly seasonal, being weaker in winter and stronger in summer, and is affected by the winds in that area. In addition to the West Australian Current flowing
