Normally an oceanographic phenomenon known as upwelling keeps the surface waters of the southeast Pacific Ocean cold and teeming with small pelagics that are fished by purse seiners. Upwelling occurs in this zone when southeasterly trade winds , produced by the South Pacific anti-cyclone, along with other facto rs drive coastal waters out to sea, forcing deep nutrient-rich waters to rise.
