Impact On Shellfish From Ocean Acidification
2012-08-06 14:24:57

redOrbit Staff & Wire Reports - Your Universe Online In the journal Global Change Biology, a worldwide study is published to understand and forecast the likely impact of ocean acidification on shellfish and other marine life living in seas from the tropics to the north and south poles. Ocean acidification is occurring because some of the increased carbon dioxide humans are adding to the atmosphere dissolves in the ocean and reacts with water to produce an acid. According to the...

As the famous saying goes “success breeds success” so it is no surprise that leading engineering, materials technology and composite processing firm Gurit have taken the proactive approach in 2012 to showcase their excellence as it relates to tidal energy LONDON (PRWEB) August 03, 2012 Recent increase in support for Wave & Tidal energy in the UK, up from 2 ROCs to 5 ROCs, will stimulate the marine sector. Smart companies are positioning themselves to succeed in this emerging...

Arctic Waters Invaded By Tropical Plankton
2012-07-25 08:29:52

Researchers see natural cycle; but questions arise on climate change For the first time, scientists have identified tropical and subtropical species of marine protozoa living in the Arctic Ocean. Apparently, they traveled thousands of miles on Atlantic currents and ended up above Norway with an unusual–but naturally cyclic–pulse of warm water, not as a direct result of overall warming climate, say the researchers. On the other hand: arctic waters are warming rapidly, and such...

Greenland Ice Melt Is "Unprecedented"
2012-07-25 06:04:10

Lee Rannals for redOrbit.com - Your Universe Online Satellites have revealed that Greenland's surface ice cover has melted this month more than any time in over 30 years of satellite observations. NASA said that nearly the entire ice cover of Greenland experienced some degree of melting at its surface this past month. Measurements from three independent satellites were analyzed by NASA and university scientists, who found that 97 percent of the ice sheet surface in Greenland thawed...

Hatches Close On Aquarius Lab, Possibly For The Last Time
2012-07-23 14:13:19

Lee Rannals for redOrbit.com - Your Universe Online Aquanauts could now officially be a thing of the past, as Sunday saw the doors of the undersea research lab Aquarius Reef Base close for the last time. The National Oceanic and Atmospheric Administration's (NOAA) lab was established in 1986, and operated around the U.S. Virgin Islands for over two decades at 60 feet below the surface of the ocean. Federal budget cuts have left the Aquarius lab without its $3 million annual funding,...

Past Climate Change Linked With Ancient Alteration of Seawater Chemistry
2012-07-20 15:41:27

Dissolution or creation of huge gypsum deposits changed sulfate content of the oceans Scientists have discovered a potential cause of Earth's "icehouse climate" cooling trend of the past 45 million years. It has everything to do with the chemistry of the world's oceans. "Seawater chemistry is characterized by long phases of stability, which are interrupted by short intervals of rapid change," says geoscientist Ulrich Wortmann of the University of Toronto, lead author of a paper...

Managers who have more -- and more subtle — tools may be able to generate more profit from a sustainable fishery than they can using marine protected areas alone As spatial planning is used increasingly to manage fisheries and other ocean resources, researchers are working to determine the best ways to use and refine the various spatial management tools. Among them are marine protected areas (MPAs), one of the most common methods, which limit or entirely curtail fishing in a given...

The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models. The process, named 'saddle-collapse', was found to be the cause of two rapid sea level rise events: the Meltwater pulse 1a (MWP1a) around 14,600 years ago and the '8,200 year' event. The research is published today in Nature. Using a climate model, Dr Lauren Gregoire of Bristol's School of Geographical Sciences and colleagues unearthed the series of...

UK scientists will measure the effect on the marine environment and wildlife of devices that harness tide and wave energy using sonar technology that has, for the first time, been successfully deployed on the seabed. Renewable energy from tidal currents can be generated using turbines in the tidal flow, and wave energy can be captured in a number of different ways. FLOWBEC (Flow and Benthic Ecology 4D) is a three-year, £1.2 million project that brings together a consortium of...

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

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...
