Powerful Magnitude 7.0 Earthquake Rocks Japan, Touches Off Small Tsunami
2012-12-07 09:00:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Japan, still reeling with the aftermath of a powerful earthquake and destructive tsunami in March 2011, has been hit again. A magnitude 7.3 earthquake struck off the coast at 5:18 p.m. local time Friday evening triggering a small 3-foot-high tsunami that swept against the Japanese mainland nearly 45 minutes later. Evacuation orders came streaming in over TV and radio channels shortly after the quake struck and countless coastal...

On December 6, NOAA will release a technical report that estimates global mean sea level rise over the next century based on a comprehensive synthesis of existing scientific literature. The report finds that there is very high confidence (greater than 90% chance) that global mean sea level will rise at least 8 inches (0.2 meters) and no more than 6.6 feet (2 meters) by 2100, depending upon uncertainties associated with ice sheet loss and ocean warming. The actual amount of sea level change...

Research Shows Sea-Level Rise Is Much Faster Than Previously Reported
2012-11-28 12:18:17

Lawrence LeBlond for redOrbit.com - Your Universe Online The Intergovernmental Panel on Climate Change (IPCC) has been keeping a close eye on rising sea levels and has released several reports outlining the forecasts for the future of our world´s oceans. In its fourth assessment report, released in 2007, the IPCC estimated sea levels were rising at a rate of 0.08 inches per year based on satellite data. But new research from the Potsdam Institute for Climate Impact Research, Tempo...

Ocean Acidification Threatens Antarctic Marine Wildlife
2012-11-26 05:01:08

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has uncovered the first evidence that marine creatures living in the Antarctic region are being affected by ocean acidification. That evidence was discovered in 2008, when researchers from the British Antarctic Survey (BAS), the University of East Anglia (UEA), the Woods Hole Oceanographic Institution (WHOI) and the National Oceanic and Atmospheric Administration (NOAA) observed that the shells...

Scientists Present Recent Findings On The Subsurface Biosphere
2012-11-19 14:27:31

National Science Foundation "Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?" So wrote Jules Verne almost 150 years ago in A Journey to the Center of the Earth. Verne probably couldn't have imagined the diversity of life that researchers observe today under the ocean floor. Scientists affiliated with the National Science Foundation (NSF) Center for Dark Energy...

Tropical Indo-Pacific Climate Changes To A More El Niño-like State
2012-11-15 11:57:55

University of Hawaii “‘ SOEST The Walker circulation determines much of the tropical Indo-Pacific climate and has a global impact as seen in the floods and droughts spawned by the El Niño-Southern Oscillation. Meteorological observations over the last 60 years show this atmospheric circulation has slowed: the trade winds have weakened and rainfall has shifted eastward toward the central Pacific. The immediate cause of this slowdown has puzzled climate...

Greenland Could Be Affected By Warming Temperatures
2012-11-14 09:01:27

April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...

The terms “gas” and “sea” for many will invoke associations of reserves, business, and a lot of money. Whatever the association, most of the efforts in Israel´s energy field are being directed at gas buried deep under the Mediterranean seabed. Now a new geophysical study, the first of its kind in Israel, has uncovered a system of active gas springs in the Haifa Bay seabed, at relatively shallow depths, only a few dozen meters below the surface. The study,...

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...
