Latest Oceanography Stories
A leading group of scientists and experts recently released a report that emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change.
Residents of Alaska and parts of Canada were briefly under a tsunami warning on Saturday after a strong earthquake rocked the region, but the alert was later cancelled because no potentially destructive waves resulted from the trembler.
Scientists have discovered corals at Australia’s Great Barrier Reef at depths that were previously believed to be uninhabitable.
The most pressing issues that UK marine science needs to address over the next two decades are the subject of a prospectus published as a themed issue of the Philosophical Transactions of the Royal Society A last month.
A magnitude 7.3 earthquake struck off the coast at 5:18 p.m. local time Friday evening triggering a small 3-foot-high tsunami that swept against the Japanese mainland nearly 45 minutes later.
On December 6, NOAA will release a technical report that estimates global mean sea level rise over the next century based on a comprehensive synthesis of existing scientific literature.
The Intergovernmental Panel on Climate Change (IPCC) has been keeping a close eye on rising sea levels and has released several reports outlining the forecasts for the future of our world’s oceans.
An international team of researchers has uncovered the first evidence that marine creatures living in the Antarctic region are being affected by ocean acidification.
"Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?"
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...
