Last Glacial Age Decimated Global Killer Whale Population
2014-02-05 09:53:07

[ Watch the Video: Ice Age Decimated Killer Whales ] Brett Smith for redOrbit.com - Your Universe Online 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. The study, which was published in the journal Molecular Biology and Evolution, is based on a genetic analysis of archival DNA that showed significant genetic diversity bottlenecks in orca...

Scientists Demonstrate Influence Of Eddies On The Oxygen Sustenance
2013-11-18 13:25:24

GEOMAR Helmholtz Centre for Ocean Research Kiel 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. First results of the project carried out in the context of the Collaborative Research Centre (SFB) 754 “Climate-biogeochemistry interactions in the tropical ocean” show, how eddies in the ocean influence the oxygen and nutrient distribution in the...

Wobble Of The Earth Rings The Ocean Dinner Bell For Tiny Ocean Creatures
2013-09-14 04:18:52

redOrbit Staff & Wire Reports - Your Universe Online 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, researchers from Princeton University and the Swiss Institute of Technology in Zurich (ETH) claim in research appearing in the journal Nature. According to the study authors, the discovery will give scientists new insight into how the ocean regulates its own life-support system,...

California Coastal Fog Contains Rising Levels Of Methylmercury
2012-12-05 10:58:48

Brett Smith for redOrbit.com - Your Universe Online Scientists from California have linked rising levels of methylmercury in their state´s coastal fog to upwelling from deep ocean water. Lead researcher Peter Weiss-Penzias, an environmental toxicologist at the University of California, Santa Cruz, was quick to point out that the amount of the toxic mercury compound detected in coastal fog is not a direct public health concern. "These are parts-per-trillion levels, so when we say...

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. ESA's CoastColour project is helping scientists develop techniques to take full advantage of the unique capabilities of the Medium Resolution Imaging Spectrometer (MERIS) sensor on its Envisat satellite. With a resolution of 300 m, MERIS provides the sharpest view of coastal waters to date, and includes spectral...

Research suggests that the amount of phytoplankton found in the top layers of the ocean has declined markedly over the last century. Scientists wrote in the journal Nature that the decline appears to be linked to rising water temperatures. The researchers looked at records of the transparency of sea water, which is affected by the plants.  The decline could be ecologically significant as plankton sit at the base of marine food chains. This is the first study that has attempted a...

The ongoing El Niño of 2010 is affecting north Pacific Ocean ecosystems in ways that could affect the West Coast fishing industry, according to scientists at NOAA and Scripps Institution of Oceanography, UC San Diego. Researchers with the California Cooperative Oceanic Fisheries Investigations (CalCOFI) at Scripps and NOAA's Southwest Fisheries Science Center report a stronger than normal northward movement of warm water up the Southern California coast, a high sea-level...

The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwelling. Now a research team headed by Brown University marine ecologist Jon Witman has found the opposite to be true: Barnacle populations thrive in vertical upwelling zones in moderately deep waters in the Galapagos Islands. The findings appear in Ecological Monographs. There's been a rich debate in marine ecological circles about what happens to a key food source along rocky...

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. However, a new study led by Professor Andreas Oschlies of the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, pours cold water on the idea. "Computer simulations show that climatic benefits of the proposed geo-engineering scheme would be modest, with the potential to...

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. Long associated with cold water, coastal upwelling is the mechanism responsible for California's productive waters. It draws cool, nutrient-rich water to the surface, promoting the growth of algae and boosting...

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...
