Zooplankton Among First To Show Evidence Of Exposure To Deepwater Horizon Oil
2012-03-23 05:24:35

Ryan Parson for Redorbit.com Oil remnants from the Maconda-1 oil field have been discovered in animals in the northern Gulf of Mexico. Zooplankton samples collected from the Gulf of Mexico have shown positive evidence of exposure to oil that may have directly originated from the Deepwater Horizon oil spill. The effects of the deadly British Petroleum R/V Deepwater Horizon oilrig explosion that took place on April 20, 2010, will more than likely be present for many years to come....

Marine Protected Areas Prove To Be Vital Aspect Of Green Turtle Sustainability
2012-03-21 05:08:51

Ryan Parson for RedOrbit.com Some sea turtles appear to be reaping the benefits of government designated areas of bodies of water, known as Marine Protected Areas (MPAs). A recent study published in the journal Global Ecology and Biogeography suggests that the MPAs are playing a key role in the support and nourishment of the Green turtle. According to the National Marine Fisheries Service, all six species of sea turtles that inhabit US waters are currently listed under the Endangered...

Image 1 - Weather Forecasters Balance Experience With Technology
2012-03-21 04:33:26

When people talk about a meteorologist cooking up a weather forecast, they may be more right than they realize, said one of the forecasters NASA counts on to predict conditions ahead of a launch. "I compare forecasting a lot to cooking, to be honest," said Joel Tumbiolo, a meteorologist with the Air Force's 45th Weather Squadron, the unit that handles forecasting for rockets launched at the Eastern Range on the Atlantic Coast of the United States. "In cooking, you have recipes that you...

Image 1 - Global Sea Level Could Rise As Much As 70 Feet In The Future
2012-03-21 04:04:57

Scientists looked back in time - in the geologic record - to see the future Even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit)--as the Intergovernmental Panel on Climate Change (IPCC) recommends--future generations will likely have to deal with a completely different world. One with sea levels 40 to 70 feet higher than at present, according to research results published this week in the journal Geology. The scientists, led by Kenneth...

The most comprehensive dataset of surface water carbon dioxide (CO2) measurements for the world's oceans and coastal seas is launched today by an international team of scientists led by the University of East Anglia (UEA). The Surface Ocean CO2 Atlas (SOCAT) comprises 6.3 million global observations made from research vessels, commercial ships and moorings around the world since 1968. The dataset documents the changes in ocean carbon similar to the Mauna Loa record — or 'Keeling...

Rising Sea Levels Could Boost Storm Surges
2012-03-16 05:19:24

Sea level rise due to global warming has already doubled the annual risk of coastal flooding of historic proportions across widespread areas of the United States, according to a new report from Climate Central. By 2030, many locations are likely to see storm surges combining with sea level rise to raise waters at least 4 feet above the local high-tide line. Nearly 5 million U.S. residents live in 2.6 million homes on land below this level. More than 6 million people live on land below 5 feet;...

Evidence In Bahamas And Bermuda Suggests Increased Rise In Sea Levels
2012-03-15 11:45:55

Scientists are now predicting sea levels will climb another several inches -- or even a few feet -- by the year 2100, according to recent studies. Studying cliffs and ancient reefs on the sub-tropical islands of the Bahamas and Bermuda, scientists are investigating global sea rise and comparing these results against data from more than a century ago. The Bahamas and Bermuda have been attracting fossil hunters for many years. The land on the Bahamas, for example, is built on a foundation...

But projections for increase today still loom large The seas are creeping higher as the planet warms. But how high will they go? Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers; by pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level...

Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests. A new study, published today, 14 March, in IOP Publishing's journal Environmental Research Letters, asserts that around 32,000 km2 of US land lies within one vertical meter of the high tide line, encompassing 2.1 million housing units where 3.9 million people live. For this study, the...

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees global warming has been observed. Substantial...

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...

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...
