Unexpected Plume Challenges Iron Estimates
2013-08-20 08:47:27

April Flowers for redOrbit.com - Your Universe Online A vast plume of iron and other micronutrients more than 620 miles long has been discovered billowing from hydrothermal vents in the South Atlantic Ocean. Teams of scientists from Woods Hole Oceanographic Institute (WHOI) and the University of Liverpool, UK say their findings, published in an upcoming issue of Nature Geoscience, call into question past estimates of iron abundances and may challenge researchers’ previous assumptions...

Corals can survive the early stages of their development even under the tough conditions that rising carbon emissions will impose on them says a new study from the ARC Centre of Excellence for Coral Reef Studies. Globally, ocean acidification due to the burning of fossil fuels remains a major concern and scientists say it could have severe consequences for the health of adult corals, however, the evidence for negative effects on the early life stages of corals is less clear cut. Dr...

USGS Maps California Seafloor In Unprecedented Detail
2013-08-12 14:59:57

Peter Suciu for redOrbit.com - Your Universe Online While California offers an impressive shoreline, new research has been able to look beyond just the surface and has been used to reveal the hidden seafloor in unprecedented detail. Three new products in an ongoing series were released last week by the US Geological Survey (USGS), and include a map set for the area offshore of Carpinteria, a catalog of data layers for geographic information systems and even a collection of videos and...

Underwater Volcano System Proposed As National Park For Norway
2013-08-05 05:11:28

Susan Bowen for redOrbit.com - Your Universe Online Off the coast of Norway, on the floor of the Arctic Ocean, lies a largely unexplored world of undersea volcanoes. This system, with the fanciful name of Loki's Castle, contains rich metal deposits and unique wildlife. This field of five active hydrothermal vents was discovered in 2008. A team from the University of Bergen (UiB), led by Professor Rolf Birger Pedersen, continues to make discoveries at the site, which is thought to be the...

Coastal American Cities Threatened By Sea-Level Rise
2013-07-31 08:55:40

Michael Harper for redOrbit.com - Your Universe Online Boston, Miami, New York and more than 1,700 other coastal American cities are facing a greater risk from rising sea levels than had previously been estimated. A new study published in the Proceedings of the National Academy of Sciences (PNAS) claims at least 316 American cities will one day be overtaken by the sea if pollution continues to grow as it has been. More than 1,400 other cities will be "locked-in" by rising sea...

How Cold, Deep Ocean Waters Influence Sea Surface Temperatures
2013-07-26 06:04:28

Brett Smith for redOrbit.com - Your Universe Online Newly published research from Oregon State University has revealed new details on the forces behind El Nino and could lead to more refined predictions for global warming. According to their report in the journal Nature, OSU scientists have used new measurements of ocean mixing to record the first multi-year data set that will allow for a comprehensive analysis of how cold, deep ocean waters can influence sea surface temperatures on a...

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

National Oceanography Centre, Southampton (UK) The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the...

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

Russia Blocks Antarctic Sanctuary
2013-07-17 08:34:56

redOrbit Staff & Wire Reports - Your Universe Online Russia has blocked attempts to establish marine reserves in the Ross Sea and Eastern Antarctica, preventing the formation of what would have become the world's largest ocean sanctuary. According to BBC News, the Russian representative challenged the legality of a meeting that would have allowed for the creation of the reserves. The three-day-long conference, held in Bremerhaven, Germany was called by the Commission for the...

Baffin Bay
2013-04-18 13:21:50

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...

Current Sea Level Rise
2013-04-01 10:39:21

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
2013-04-01 10:32:20

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...

Basic Ocean Terms
2013-02-05 12:52:11

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...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

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...
