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...

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

Brett Smith for redOrbit.com - Your Universe Online 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? According to a new paper in Science Express, the North American shoreline of over 3 million years ago sits more than 280 feet above the modern sea level from Virginia to Florida. Using computer modeling to account for sediment buildup...

Labrador Sea To Be The Subject Of New Ocean Study
2013-05-22 05:50:19

April Flowers for redOrbit.com - Your Universe Online The Natural Sciences and Engineering Research Council of Canada has awarded Paul Myers, a professor in the Department of Earth and Atmospheric Sciences at the University of Alberta, nearly $5 million for his study of deep ocean exchanges of carbon dioxide. The study, titled “Ventilation, Interactions and Transports Across the Labrador Sea,” will receive the award over the next five years. Myers says he chose the Labrador...

Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset. For the devastating Japan 2011 event, the team reveals that the analysis of the GPS data and issue of a detailed tsunami alert would have taken no more than three minutes. The results are published on 17 May in Natural Hazards and Earth System...

April Flowers for redOrbit.com - Your Universe Online According to the most recent Ecosystem Advisory issued by NOAA's Northeast Fisheries Science Center (NEFSC), sea surface temperatures (SSTs) for 2012 in the Northeast Shelf Large Marine Ecosystem were the highest recorded in 150 years. These record SSTs are the latest in a trend of above average temperatures observed during the spring and summer seasons and part of a pattern of elevated temperatures in the Northwest Atlantic. This trend...

In 2009, the North Carolina Coastal Resources Commission (CRC), a body that controls and regulates coastal development in North Carolina, asked 13 members of its advisory Science Panel to prepare a report on the state of sea-level rise in North Carolina. After the report was published, there was a subsequent maelstrom regarding its utility and validity. In this month's issue of EARTH Magazine, Orrin Pilkey and Alexander Glass from Duke University describe what happened. Based on the...

ESA’s SMOS And NASA’s Aquarius Missions Monitoring Ocean Salinity
2013-04-22 14:21:15

ESA [ Watch The Video Freshwater Plume From SMOS And Aquarius ] The saltiness of the oceans is being closely monitored from space by both ESA´s SMOS and NASA´s Aquarius missions, but in slightly different ways. By joining forces, researchers are exploiting these complementary missions to benefit climate science even further. Everyone knows that seawater is salty, but it isn´t that obvious that the concentration of salt — the salinity — of the surface waters...

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...
