Latest Oceanography Stories
Advancements in extraction technology have made minerals and other resources in the deep sea more accessible than ever, yet knowledge of how the pursuit of these resources might affect the surrounding deep-sea ecosystem is somewhat limited.
Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.
With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean. However, a team of researchers has found that their abundance could be at least 10 times higher.
More long-term research is necessary for an accurate determination of how marine species will cope with increasing ocean acidification, according to new research.
After a three-year overhaul and major upgrade, the United States' deepest-diving research submersible, Alvin, has been cleared to return to work exploring the ocean's depths.
Scientist at Woods Hole Oceanographic Institution requests the public's help in a West Coast-based Fukushima radiation study that uses Onset TidbiT® water temperature data loggers.

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.
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.
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...
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
