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...

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

April Flowers for redOrbit.com - Your Universe Online When thick ice covered the Arctic during the last ice age, many scientists assumed that the deep currents below the ice that feed the North Atlantic Ocean and help drive the global ocean currents slowed or possibly even stopped. 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. These findings, published in the journal...

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

Rebekah Eliason for redOrbit.com — Your Universe Online Humans constantly produce carbon dioxide (CO2), both naturally and as a byproduct of industrial processes. The ocean absorbs about 25 percent of the carbon dioxide emitted by human activity. Tiny organisms called plankton live in the ocean and break down this natural greenhouse gas by converting itinto sugars and carbohydrates through photosynthesis. In order to understand the efficiency of the ocean´s carbon...

Researchers Map New Jersey Sea-Level Changes Over Last 10,000 Years
2013-05-29 09:07:40

April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...

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

Lee Rannals for redOrbit.com - Your Universe Online Ocean data collected over 135 years ago by the crew of the HMS Challenger oceanographic expedition has helped confirm global warming. Researchers from NASA and the University of Tasmania used the data to provide further confirmation that humans have played a part in today's changing global climate. The team combined the ship's measurements of ocean temperatures with modern observations from the international Argo array of ocean...

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

redOrbit Staff & Wire Reports - Your Universe Online Climate experts from the University of Hawai'i at Manoa Meteorology Department and International Pacific Research Center 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. As it turns out according to researchers, "An unusual wind pattern that straddles the equatorial Pacific during strong El Nino events and swings back...

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...
