Latest Physical oceanography Stories
Scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation (ENSO), a Pacific Ocean climate cycle that affects weather patterns worldwide, by examining a set of 7,000-year-old coral fossils.
The intense, small scale storms known as polar lows could have a tremendous impact on oceanic water circulation and climate predictions, a team of researchers from the US and UK have discovered.
An international group of oceanographers has published new observations that may improve our ability to predict future changes in ice sheet mass.
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.
A research team from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association has evaluated 23 current climate models to assess their ability to predict the weather conditions for the coming year or even the next decade.
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.
A new Endangered Species Act listings proposed by NOAA would cover 66 coral species found in the Pacific and in the Caribbean.
In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date.
World Meteorological Association (WMO) reports on a global warming trend experienced during the first 10 months of 2102.
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...
