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.
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.
New research of 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.
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.
New research from an international team of researchers has found that if more carbon dioxide makes its way into the ocean – conch snails will be more vulnerable to predation.
A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary.
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.
On Thursday, NASA and the Japan Aerospace Exploration Agency announced the date and window -- Feb. 27 from 1:07 pm to 3:07 pm EST -- for the launch of a new precipitation satellite.
Amphipods typically found in the Atlantic Ocean are now reproducing in the Arctic waters west of Spitsbergen, Norway.
Researchers at the National Oceanography Center say that the risk posed by tsunami waves generated by Canary Island landslides may need re-evaluation. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.
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...
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 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...
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...
