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

According to a new report, two researchers have identified key acoustic characteristics of the 2011 Japan earthquake that could be used to significantly improve tsunami warning systems.

Ice Age Did Not Stop The Arctic Current From Flowing
2013-05-30 05:30:24

A new study reveals that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times.

Absence Of Modern Day Greenhouse Gas Emissions Revealed By NRL Geochemistry Survey At Chatham Rise
2013-05-29 13:48:18

U.S. Naval Research Laboratory Geochemistry analysis conducted by the U.S. Naval Research Laboratory of fossil sediment injection structures off the New Zealand coast in February and March reveal no presence of modern day expulsions of methane gas, a potential contributor to global 'greenhouse effect' warming. The main focus of this most recent expedition was to investigate the geological origin of seafloor anomalies discovered during a 2007 marine-life survey on the Chatham Rise....

Dead Jellyfish Help Absorb Carbon Dioxide
2013-05-29 09:55:33

Along with other sea organisms, jellyfish are part of the ocean’s natural carbon recycling process. Jellyfish eat microscopic plankton and consequently ingest broken down carbon dioxide. Dead jellyfish then sink to the bottom of the ocean taking a large amount of carbon with them. This carbon becomes trapped in the deep sea water, allowing room for more carbon dioxide to dissolve into the ocean.

Researchers Map New Jersey Sea-Level Changes Over Last 10,000 Years

The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. But the majority of the destruction came from the storm surge and flooding that followed the storm.

Century Old Data Helps Study Climate Change
2013-05-28 15:27:51

Ocean data collected over 135 years ago by the crew of the HMS Challenger oceanographic expedition has helped confirm global warming.

El Nino Has A New Rhythm
2013-05-27 04:59:39

Climate experts have reportedly discovered why the weather phenomenon known as El Nino typically peaks around Christmas and ends sometime between the months of February and April.

Mantle Influences Long-Term Sea-Level Rise Estimates
2013-05-24 04:51:40

Many climate models that are based on ancient sea levels warn about the impending dangers of modern-day sea level rise, but what if the Earth beneath our shorelines has shifted over millions of years?

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...
