NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

ocean garbage

Chuck Bednar for redOrbit.com - Your Universe Online Scientists from the University of New South Wales in Australia have developed a new model which divides the world’s oceans into seven primary regions that experience little intermingling of water, but their research has also revealed the existence of flotillas of garbage located in large, circular ocean currents known as gyres. One of those trash flotillas, the Great Pacific Garbage Patch, is a region of environmental concern...

redOrbit Staff & Wire Reports - Your Universe Online Over four billion years ago, giant asteroid impacts collided with the Earth’s surface and gave the planet a facelift of sorts – mixing, burying and melting the landscape, according to a new terrestrial bombardment model devised by an international team of researchers from various academic and government institutions. The new model was based on existing lunar and terrestrial data, and according to the authors of a new paper...

Southern Ocean waves
2014-07-22 03:30:24

University of Southampton A new study has found that turbulent mixing in the deep waters of the Southern Ocean, which has a profound effect on global ocean circulation and climate, varies with the strength of surface eddies – the ocean equivalent of storms in the atmosphere – and possibly also wind speeds. It is the first study to link eddies at the surface to deep mixing on timescales of months to decades. This new insight into how the Southern Ocean behaves will allow...

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

With about 4.3 billion people, it hosts 60 percent of the world’s current human population. This continent has a high growth rate in the modern era. For example, during the 20th century, Asia’s population almost quadrupled. This continent is defined as making up the...

Ocean Analysis for November 17, 2012

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

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...
