Thriving Colonies Of Microbes Discovered In Ocean 'Plastisphere'
2013-06-27 15:28:13

Woods Hole Oceanographic Institution Scientists have discovered a diverse multitude of microbes colonizing and thriving on flecks of plastic that have polluted the oceans--a vast new human-made flotilla of microbial communities that they have dubbed the "plastisphere." In a study recently published online in Environmental Science & Technology, the scientists say the plastisphere represents a novel ecological habitat in the ocean and raises a host of questions: How will it change...

New Report Says Sea Level Along Maryland's Shorelines Could Rise Two Feet By 2050
2013-06-26 14:47:56

University of Maryland Center for Environmental Science A new report on sea level rise recommends that the State of Maryland should plan for a rise in sea level of as much as 2 feet by 2050. Led by the University of Maryland Center for Environmental Science, the report was prepared by a panel of scientific experts in response to Governor Martin O'Malley's Executive Order on Climate Change and "Coast Smart" Construction. The projections are based on an assessment of the latest climate...

Mixed News For Pacific Northwest Oyster Industry In World Oceans Month
2013-06-13 10:38:01

National Science Foundation Ocean acidification inhibits shell formation, but interventions at hatcheries may offset some effects, scientists find For the past several years, it has struggled with significant losses due to ocean acidification. Oyster larvae have had mortality rates high enough to render production no longer economically feasible. Now a new study documents why oysters appear so sensitive to increasing acidity, but also offers some hope for the future. It isn't...

Microbes are living more than 500 feet beneath the seafloor in 5 million-year-old sediment, according to new findings by researchers at the University of Delaware and Woods Hole Oceanographic Institution (WHOI). Genetic material in mud from the bottom of the ocean – called the deep biosphere –revealed an ecosystem of active bacteria, fungi and other microscopic organisms at depths deeper than a skyscraper is high. The findings were published in Nature on June 12. “This...

Earthquake Sounds Help Predict Tsunamis
2013-06-07 11:27:11

Brett Smith for redOrbit.com - Your Universe Online While seismologists have the ability to detect undersea earthquakes, they don´t know which ones will turn into tsunamis. Some ocean-based sensors are able to detect an approaching tsunami, but they can only provide a few minutes of advanced warning. According to a new report in The“¯Bulletin of the Seismological Society of America, two Stanford University researchers have identified key acoustic characteristics of 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

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...
