redOrbit Staff & Wire Reports - Your Universe Online By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor. Scientists have known for several decades that the seafloor is formed throughout the major ocean basins at the linear chains of volcanoes known...
Lawrence LeBlond for redOrbit.com - Your Universe Online On the one-year anniversary of legendary filmmaker/director James Cameron’s descent to the bottom of the world, the submarine he used to make that solo descent – a nearly 7 mile journey to the bottom of the Mariana Trench in the Pacific Ocean – is being donated to science. Cameron, famed director of the blockbuster movies “Titanic” and “Avatar,” told BBC News that he would be donating his Deepsea Challenger to the...
Forms partnership with WHOI to accelerate technology development, ocean research and discovery WOODS HOLE, Mass., March 26, 2013 /PRNewswire/ -- Explorer and filmmaker James Cameron and Woods Hole Oceanographic Institution (WHOI) have formed a partnership to stimulate advances in ocean science and technology and build on the historic breakthroughs of the 2012 Cameron-?led DEEPSEA CHALLENGE expedition exploring deep-ocean trenches. The announcement comes on the one-year...
New mathematical tool developed by a Scripps scientist can help avoid misleading conclusions for species management In the early 1940s, California fishermen hauled in a historic bounty of sardine at a time that set the backdrop for John Steinbeck's "Cannery Row" novel. But by the end of the decade the nets came up empty and the fishery collapsed. Where did they all go? According to a new study led by scientists at Scripps Institution of Oceanography at UC San Diego, the forces behind the...
Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island just to the...
Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that warming oceans and ocean acidification threaten to destroy the ocean’s coral reefs. Now, a new study from Australian researchers published in the journal Global Change Biology suggests that yet another threat could decimate these delicate ecosystems. “Our research shows that when seawater is both acidic and warm – which is predicted to happen under future climate scenarios – coral reefs could be...
AlphaGalileo Foundation To study the effects of ocean acidification, ten huge plastic containers called mesocosms are placed in the Gullmar Fjord in Sweden. The project is unique: mesocosms of this size have never been used for such a long period of time. The experiment is part of a worldwide research project, and includes researchers from the University of Gothenburg, Sweden. This is the largest and longest experiment on the impact of climate change on marine ecosystems that have been...
Sentry Releases FAQs on GPO Prohibition Policy DEERFIELD BEACH, Fla., March 12, 2013 /PRNewswire/ -- Sentry Data Systems, Inc. is reaching out to the 340B community to address concerns regarding Covered Entities (CEs) meeting the requirements stated in the Health Resources and Services Administration's (HRSA's) recently released GPO Prohibition Policy guidance. Sentry has been consistently proactive in monitoring 340B policy updates and is dedicated ?to providing 340B software...
[ Watch the Video: Animation of a Tsunami Wave ] April Flowers for redOrbit.com - Your Universe Online An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis. These zones can produce a focusing point that creates massive and devastating tsunamis capable of breaking the rules by which scientists used to think tsunamis worked. Previously, scientists largely...
Research reveals importance of location, location, location Fishers near marine protected areas end up traveling farther to catch fish but maintain their social and economic well-being, according to a study by fisheries scientists at Washington State University and in Hawaii. The study, reported in the journal Biological Conservation, is one of the first to look closely at how protected areas in small nearshore fisheries can affect where fishers operate on the ocean and, as a...

Baffin Bay, which is located between Baffin Island and the southwest coast of Greenland, is a marginal sea of the North Atlantic Ocean. It’s connected to the Atlantic by Davis Strait and the Labrador Sea. A narrower Nares Strait connects the Baffin Bay with the Arctic Ocean. The Baffin Bay is an arm of the Atlantic Ocean that is bordered by Baffin Island towards the west, Greenland towards the east, and Ellesmere Island towards the north. It is connected to the Atlantic through the Davis...
The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...
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...
