Southern Ocean waves
2014-07-22 03:30:24

University of Southampton A new study has found that turbulent mixing in the deep waters of the Southern Ocean, which has a profound effect on global ocean circulation and climate, varies with the strength of surface eddies – the ocean equivalent of storms in the atmosphere – and possibly also wind speeds. It is the first study to link eddies at the surface to deep mixing on timescales of months to decades. This new insight into how the Southern Ocean behaves will allow...

NASA NASA embarks this week on a coordinated ship and aircraft observation campaign off the Atlantic coast of the United States, an effort to advance space-based capabilities for monitoring microscopic plants that form the base of the marine food chain. Phytoplankton, tiny ocean plants that absorb carbon dioxide and deliver oxygen to Earth’s atmosphere, play a major role in the global cycling of atmospheric carbon between the ocean and the atmosphere. NASA has long used satellites to...

Thirteen undergraduate students from colleges across the country join renowned science and policy experts in SEA Semester's unprecedented research voyage. Woods Hole, MA (PRWEB) July 16, 2014 Daily Eexpedition Blog Posts: http://www.sea.edu/PIPA_Blog New England-based SEA Semester's ocean research vessel arrived Monday night in the Phoenix Islands Protected Area (PIPA) of the remote central Pacific. The 134 foot brigantine tall ship departed Honolulu on July 1, sailing over 1,600...

Belize's no-take Zones Help Rebuild Lobster, Conch, And Fish Populations
2014-07-14 03:50:14

Wildlife Conservation Society A new report from the Wildlife Conservation Society shows that no-take zones in Belize can not only help economically valuable species such as lobster, conch, and fish recover from overfishing, but may also help re-colonize nearby reef areas. The report—titled "Review of the Benefits of No-Take Zones"—represents a systematic review of research literature from no-take areas around the world. The report was written by Dr. Craig Dahlgren, a recognized...

Ocean's Most Abundant Organisms Have Clear Daily Cycles
2014-07-11 03:04:06

University of Hawaiʻi at Mānoa Coordinated timing may have implications for energy transformation, ocean food web Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found.  Now scientists have discovered that communities of these ocean microbes have their own daily cycles—not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times....

Chilean Devil Rays Found To Be Among The Deepest Sea Divers
2014-07-02 07:30:09

April Flowers for redOrbit.com - Your Universe Online Researchers have always believed that Chilean devil rays (Mobula tarapacana) mostly lived near the ocean's surface because they are most often observed gliding through shallow, warm waters. According to a new study led by the Woods Hole Oceanographic Institute (WHOI), that might not be the case. Their findings, published in Nature Communications, show that these are actually among the deepest-diving ocean animals. "So little is known...

tsunami earthquakes
2014-06-28 05:08:15

redOrbit Staff & Wire Reports - Your Universe Online “Sticking points” in the Earth’s tectonic plates caused by extinct undersea volcanoes could be responsible for producing tsunami earthquakes, a discovery which could lead to improved detection of these rare seismic events. Tsunami earthquakes typically occur at relatively shallow ocean depths and are typically of lower magnitude. However, they can create extremely large tsunamis, with earthquakes measuring as little as 5.6...

NASA/NOAA Water Vapor Animations Show Where Water Vapor Is Moving Over Oceans
2014-06-26 03:07:03

Rob Gutro, NASA Knowing where water vapor is in the atmosphere is one of many factors forecasters use to identify weather features. The NASA/NOAA GOES Project has now created two new types of animations based on satellite data that indicate where water vapor is moving over the Atlantic and Eastern Pacific oceans. Observations from the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellites (GOES) measure the local air temperature in kelvins...

NEW YORK, June 24, 2014 /PRNewswire/ -- The health of the global ocean is in decline and an integrated rescue package needs to be applied over the next five years, according to an independent international commission that published its findings today. The Global Ocean Commission, made up of former Heads of State, Government, ministers and prominent business leaders, has spent 18 months investigating the decline of the global ocean and developed a rescue package of eight...

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...
