Climate Change Impacts Will Threaten Economy, Public Health
2013-01-29 10:53:50

April Flowers for redOrbit.com - Your Universe Online A leading group of scientists and experts from the United States Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) recently released a report that emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change. The report, titled "Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013...

Tsunami Warning Cancelled After Earthquake Off Alaska Coast
2013-01-06 05:09:45

redOrbit Staff & Wire Reports - Your Universe Online Residents of Alaska and parts of Canada were briefly under a tsunami warning on Saturday after a strong earthquake rocked the region, but the alert was later cancelled because no potentially destructive waves resulted from the trembler. According to the United States Geological Survey (USGS), the magnitude 7.5 seismic event took place approximately 58 miles west of Craig, Alaska at approximately midnight local time (08:58:19 UTC)....

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered corals at Australia´s Great Barrier Reef at depths that were previously believed to be uninhabitable. A team of researchers with the University of Queensland's Seaview Survey has been working on a multi-year project to map out the Great Barrier Reef, and they recently announced that they have found corals in waters nearly as dark as night. The newly discovered corals sit at 410 feet below the surface at...

Most Pressing Marine Science Questions Addressed
2012-12-10 13:45:17

National Oceanography Centre Southampton The most pressing issues that UK marine science needs to address over the next two decades are the subject of a prospectus published as a themed issue of the Philosophical Transactions of the Royal Society A last month. The volume is co-edited and carries contributions by scientists based at the National Oceanography Centre Southampton (NOCS). Human-induced changes in ocean processes are already being observed, and are projected to intensify as...

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...

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...
