Latest Physical oceanography Stories
Boston, Miami, New York and 1,700 American cities are facing a greater risk from rising sea levels than had previously been estimated
Newly published research from Oregon State University has revealed new details on the forces behind El Nino and could lead to more refined predictions for global warming.
A team of scientists from the Universidad Carlos III of Madrid and the University of California - San Diego have created a static pipeline wave in a laboratory.
Large stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean in events over the coming decades that could aggravate sea level rise.
A large team of international researchers has looked millions of years into the Antarctic past and found evidence that massive sections of the continent's eastern ice sheet once melted to raise sea levels by around 66 feet.
According to a new study published in the Proceedings of the National Academy of Sciences, the greenhouse gases emitted today will cause the sea level to rise for centuries to come. It is estimated each degree of global warming will raise sea levels by more than two meters.
New research from a team of European scientists has found there isn't enough satellite data to determine the rate of polar ice cap melt very far into the future and warned against using current trends to predict sea level rise that might result from melting glaciers.
Greenland's ice sheet is considered an important potential contributor to future global sea-level rise over the next century or longer. It contains an amount of ice that could lead to a rise of global sea level by more than 22 feet if it completely melted.
One of the Earth's most watched glaciers, Pine Island Glacier (PIG), has released a massive iceberg about eight times the size of Manhattan Island, according to images released by the German Space Agency (DLR).
The El Nino Southern Oscillation (ENSO) is a tropical Pacific Ocean phenomenon that has important consequences for weather around the globe.
Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...
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...
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...
If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...
If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
