Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere. The researchers' findings "“ published on-line today in Nature Geoscience "“ provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial...

Discovery, a First, Could Spur Exploration of Distant Mid-Ocean Ridge Scientists at Columbia's Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments. Hydrothermal vents spew volcanically heated seawater from the planet's underwater mountain ranges"”the vast mid-ocean ridge...

Climatologists have long known that human-produced greenhouse gases have been the dominant drivers of Earth's observed warming since the start of the Industrial Revolution. But other factors also affect our planet's temperature. Of these, the ocean plays a dominant role. Its effects helped nudge global temperatures slightly higher in 2009, and, according to NASA scientists, could well contribute to making 2010 the warmest year on record. Covering 71 percent of our planet's surface, the ocean...

Evidence from the Challenger Deep "“ the deepest surveyed point in the world's oceans "“ suggests that tiny single-celled creatures called foraminifera living at extreme depths of more than ten kilometers build their homes using material that sinks down from near the ocean surface. The Challenger Deep is located in the Mariana Trench in the western Pacific Ocean. It lies in the hadal zone beyond the abyssal zone, and plunges down to a water depth of around 11 kilometers. "The...

The increasing acidity of the world's oceans - and that acidity's growing threat to marine species - are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment, says world-renowned Antarctic marine biologist Jim McClintock, Ph.D., professor in the University of Alabama at Birmingham (UAB) Department of Biology. "The oceans are a sink for the carbon dioxide that is released into the atmosphere," says McClintock,...

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated. "Climate models must take this carbon sink into account," says Mario Lebrato, lead author of the study. The work was done when he was at the National Oceanography Centre, Southampton (NOCS) and affiliated with the University of Southampton's School of Ocean and Earth Science (SOES); he is now at the...

There is little doubt among scientists now that human carbon dioxide emissions are warming the planet. Another problem of rising atmospheric carbon dioxide (CO2) is that CO2 is being absorbed by the oceans, which increases seawater acidity (lowers the seawater pH). This process, termed 'ocean acidification', has received growing scientific and public interest because it threatens certain groups of marine organisms, including corals. Only recently have researchers realized that man-made carbon...

A study published by U.S. scientists on Sunday said pollution has caused the world's oceans to become noisier, causing more harmful effects to whales, dolphins, and other marine life. These effects include death and serious injury caused by brain hemorrhages or other tissue trauma, strandings and beachings, temporary and permanent hearing loss or impairment, displacement from preferred habitat and disruption of feeding, breeding, nursing, communication, sensing and other behaviors vital to...

New discoveries about the deep ocean's temperature variability and circulation system could help improve projections of future climate conditions. The deep ocean is affected more by surface warming than previously thought, and this understanding allows for more accurate predictions of factors such as sea level rise and ice volume changes. High ocean surface temperatures have also been found to result in a more vigorous deep ocean circulation system. This increase results in a faster transport...

High-resolution computer simulations performed by scientists at the National Oceanography Centre, Southampton (NOCS) are helping to understand the inflow of North Atlantic water to the Arctic Ocean and how this influences ocean climate. The summer of 2007 saw a record retreat in Arctic sea ice, and in general Arctic climate has become steadily warmer since the early 1990s. This has changed both sea ice drift and upper ocean circulation. The warm North Atlantic water intrudes into the central...

Arctic Ocean
2013-04-18 22:31:23

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...

Asia

Asia is the world’s largest and most populous continent. It is located mainly in the eastern and northern hemispheres covering 8.7 percent of the Earth’s whole surface area and making up 30 percent of its land area. 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...

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...
