Latest Upwelling Stories
A new study from an international team of researchers has found that killer whale populations around the world were decimated by the last Ice Age that occurred around 40,000 years ago.
More than four months from November 2012 to March 2013 Kiel ocean scientists investigated on the German research vessel METEOR the oxygen-poor upwelling regions in the tropical Pacific off Peru.
The nutrient known as “fixed” nitrogen, which is essential to the health of the ocean, is controlled by the cyclic wobble of the Earth on its axis.
Scientists from California have linked rising levels of methylmercury in their state’s coastal fog to upwelling from deep ocean water.
Our growing reliance on coastal waters for food, trade and tourism means that these delicate ecosystems need to be more closely monitored to guarantee their future sustainability.
Research suggests that the amount of phytoplankton found in the top layers of the ocean has declined markedly over the last century.
The ongoing El NiÃ±o of 2010 is affecting north Pacific Ocean ecosystems in ways that could affect the West Coast fishing industry.
The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwelling.
Pumping nutrient-rich water up from the deep ocean to boost algal growth in sunlit surface waters and draw carbon dioxide down from the atmosphere has been touted as a way of ameliorating global warming.
Using algae records from the early Pliocene, when earth's climate was warmer, scientists are finding evidence which suggests that coastal upwelling off the California coast was sustained in this period even though sea surface temperatures were several degrees higher than today.
The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...
Coastal Upwelling- this is defined as the moving of water from the deeper oceans upwards to the surface of the ocean very commonly found along our cold ocean currents, which are found along the West Coast of the United States and off the Peru coast. Coastal Sinking- this is defined as the warm waters moving in from the east and hitting the coastline and slowly filtering down towards the deeper ocean waters very slowly. This feature is common in our warm ocean currents such as the United...
