2013 Seventh Warmest Year On Record
2014-01-21 12:42:19

[ Watch The Video: Six Decades Of A Warming Earth ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Goddard Institute for Space Studies (GISS) in New York found that 2013 tied 2009 and 2006 for the seventh warmest year since 1880. GISS analyzes global surface temperatures and released an updated report on Tuesday on the 2013 temperatures from around the world. According to the report, the average temperature last year was 58.3 degree Fahrenheit, which is about 1.1 degrees...

Renewable tidal energy sufficient to power about half of Scotland could be harnessed from a single stretch of water off the north coast of the country, engineers say Renewable tidal energy sufficient to power about half of Scotland could be harnessed from a single stretch of water off the north coast of the country, engineers say. Researchers have completed the most detailed study yet of how much tidal power could be generated by turbines placed in the Pentland Firth, between mainland...

Measuring Earth’s Temperature
2014-01-14 08:16:14

ESA Like thermometers in the sky, satellite instruments can measure the temperatures of Earth’s surfaces. ESA’s new GlobTemperature project is merging these data from a variety of spaceborne sensors to provide scientists with a one-stop shop for land, lake and ice temperature data. Information on land surface temperature is a key parameter for studying the Earth system. It plays an important role in physical processes such as atmospheric convection and surface evaporation,...

Ocean Ecosystem Affected By Powerful Internal Waves: Study
2014-01-09 06:08:08

Gerard LeBlond for redOrbit.com - Your Universe Online New research on the ocean’s hidden waves was conducted in a lab and in the South China Sea. According to a January 8 report from MIT news, internal waves can be hundreds of feet tall and produce damaging effects to the climate and the ocean’s ecosystem. Experiments in laboratories and in the ocean have scientists claiming to have solved the mystery of what causes the largest internal waves in the world. The new findings,...

Projected Sea-Level Rise Could Land Coastal Los Angeles Underwater
2014-01-08 06:30:25

redOrbit Staff & Wire Reports - Your Universe Online Sea-level changes projected to occur around Los Angeles could increase the flood risk for the coastal city’s roads, wastewater systems and low-altitude communities, University of Southern California (USC) researchers claim in a new report. Current forecasts predict that Los Angeles, the most populous city in the state of California, could experience a sea-level increase of up to two feet by the year 2050, the study authors said...

Carbon Dioxide Emissions Keep Conch Snails From Escaping Predation
2014-01-07 13:18:57

Brett Smith for redOrbit.com - Your Universe Online New research from an international team of scientists has found that if more carbon dioxide makes its way into the ocean – conch snails will be more vulnerable to predation. Conch snails typically use a strong foot-like appendage to leap away from approaching predators. According to the team’s study, published in the Proceedings of the Royal Society B: Biological Sciences, when the snails are exposed to carbon dioxide levels...

Fluctuation 'adds insult to injury' for marine creatures A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary. "The natural short-term variability in acidity we observed over the course of one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms that are especially susceptible to changes in...

hydroid Corymorpha glacialis
2014-01-01 04:45:37

Ranjini Raghunath for redOrbit.com - Your Universe Online Climate change could cause a severe decline in plant and animal populations living on the ocean floor within the next hundred years, according to new research published in the journal Global Change Biology. The study predicts that ocean-bed life forms, from tiny bacteria to sponges and deep water lobsters and crabs, could decline by nearly 40 percent in the North Atlantic Ocean and over 5 percent worldwide. More than 80 percent...

NASA, JAXA Announce Launch Date For New Precipitation Satellite
2013-12-26 12:14:39

Brett Smith for redOrbit.com - Your Universe Online On Thursday, NASA and the Japan Aerospace Exploration Agency (JAXA) announced the date and window -- Feb. 27 from 1:07 pm to 3:07 pm EST -- for the launch of a new precipitation satellite. The Global Precipitation Measurement (GPM) Core Observatory satellite is slated to be launched from Japan’s Tanegashima Space Center. GPM is designed to conduct observations of rain and snowfall several times a day around the world. NASA said it...

Amphipod Species Moving Into Arctic Waters
2013-12-19 09:04:00

redOrbit Staff & Wire Reports - Your Universe Online Amphipods typically found in the Atlantic Ocean are now reproducing in the Arctic waters west of Spitsbergen, Norway, and according to research appearing in the journal Marine Ecology Progress Series, the discovery could signify a shift in the region’s zooplankton community. The presence of these creatures was discovered by biologists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), who...

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...
