Phytoplankton In The Southern Ocean
2013-09-19 04:45:00

[ Watch the Video: Phytoplankton Observed By NASA Satellites ] April Flowers for redOrbit.com - Your Universe Online Until now, NASA satellites might have missed as much as 50 percent of the phytoplankton in the Southern Ocean. This would make it far more difficult to estimate the potential carbon capture of this vast area of the sea. A new study from the University of Tasmania's Institute for Marine and Antarctic Studies (IMAS), published in the Journal of Geophysical Research, has...

ESA Astronauts Testing Sample Returns At Sea
2013-09-13 15:11:45

ESA ESA astronauts Andreas Mogensen and Thomas Pesquet are in Florida, USA for a five-day underwater adventure to test tools and practice spacewalks as part of the Seatest mission. Andreas will live in an underwater habitat with NASA astronauts Joa Acaba and Kate Rubins and Japanese astronaut Soichi Noguchi, while Thomas will stay on shore as flight director and crew communicator. Inside the Aquarius habitat, the ‘Space Environment Analog for Testing EVA Systems and Training’ –...

Tiny Plankton May Have Big Impact On Climate
2013-09-13 14:28:37

European Geosciences Union As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed. An international team of marine scientists has found that the smallest plankton groups thrive under elevated carbon dioxide (CO2) levels. This could cause an imbalance in the food web as well as decrease ocean CO2 uptake, an important regulator of global climate. The results of the study, conducted off the coast of Svalbard, Norway, in 2010, are now compiled in a special...

Receding Ice Exposes Seawater To Carbon Dioxide, Driving Ocean Acidification In The Arctic Ocean
2013-09-13 12:12:21

University of South Florida (USF Health) Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem. Ocean acidification is the process by which pH levels of seawater decrease due to greater amounts of carbon dioxide being absorbed by the oceans from the atmosphere....

Ocean Management Essential to Life and Our Future Generations (PRWEB) September 11, 2013 Accounting for seventy one percent of planet Earth, the ocean is a natural ecosystem that not only sustains marine life; it quintessentially supports a mammoth amount of the economy in America. Fisheries, tourism, and recreation all depend on the ocean for its resources. Without it, billions of dollars are at stake and the delicate dance of the economy’s balance is at risk. The ocean needs to be...

X Prize For Measuring Ocean Health
2013-09-10 11:15:29

Brett Smith for redOrbit.com - Your Universe Online Global warming alarmists and deniers alike can probably agree on at least one thing: Scientists need the most accurate data and tools to make their climate assessments. In pursuit of more accurate climate data, the X Prize Foundation has announced a $2-million competition designed to kick-start technology innovations surrounding the accurate measuring of oceanic pH. Climatologists have been warning that the world's oceans are...

Skyscraper-Size Waves Circulate Energy, Nutrients In Deep Ocean
2013-09-09 15:51:47

Brett Smith for redOrbit.com - Your Universe Online While massive waves are a surfer’s dream, they are also fascinating to oceanographers – particularly those waves breaking deep in the ocean. These deep ocean waves play a vital role in long-term climate cycles and a new study from scientists at the University of Washington has revealed waves the height of skyscrapers circulating energy and nutrients deep below the Southern Pacific Ocean. “Climate models are really sensitive...

Major players in the French tidal industry declare huge opportunity for marine energy development at the 7th International Tidal Energy Summit. London (PRWEB) September 03, 2013 This November, key companies in the French energy market will outline the opportunity and potential for development French coastal regions at the annual international meeting point for the tidal energy community. French industrial interests have weighed heavily into tidal technology in recent years with the...

Rising Sea Waters Threaten Hawaiian Shorelines
2013-08-31 08:19:16

April Flowers for redOrbit.com - Your Universe Online In Hawaii, sea-level rise (SLR) has been isolated as a principal cause of coastal erosion. After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on the islands of Oahu and Maui. A new study,...

Acoustic Wave Tsunami Warning System
2013-08-29 13:34:12

[ Watch the Video: What is a Tsunami? ] Peter Suciu for redOrbit.com – Your Universe Online While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger. Not much can be done to actually stop these natural disasters, but the earlier a warning goes out that a tsunami could strike the coast, the better the chances of effectively evacuating the area. Early warning systems play a critical role in ensuring that people reach safety,...

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...
