Explain by reference to actual examples the effects of ocean currents on climate, economy and fishing.

Some examples of the effects of ocean currents on climate, economy and fishing are as follows:

1. Newfoundland where Gulf Stream and Labrador current (cold and warm currents) meet is very important fishing ground as it provides ideal temperature conditions for the life of fish.
2. In 1912 Titanic, the largest ship of its time, off Newfoundland where Labrador Current (cold) meets Gulf Stream (warm), struck a huge iceberg and took less than 3 hours to sink. It happened due to extreme fog.
3. Winds passing over the warm currents pick up the moisture and give extra rains to British Columbia, British Isles, Japan and Queensland. Eastern margins of Australia and Africa have heavy rainfall due to the same reason.
4. Winds passing over cold currents do not rain at all, e.g., Kalahari and Atacama deserts are much drier because of cold currents.
5. The cold Labrador currents bring nearly nine months of winter and bad weather conditions prevailing over the rest of the year in Labrador and Eastern Newfoundland.
6. North Atlantic drift (warm current) has moderating effect on climate of western Europe.
7. Warm water of Tsushima current keeps the west coast of Japan warm.
8. Kuroshio current keeps the eastern coast of Japan warm.
9. Oyashio current has impact on the climate of the Russia Far East i.e. Kamchatka and Chukotka. It also forms one of the richest fishery in the world.
